1. The Working Party on General Safety Provisions (GRSG) held its 110th session from 26 to 29 April 2016 in Geneva. The meeting was chaired by Mr. A. Erario (Italy). Experts from the following countries participated in the work, following Rule 1(a) of the Rules of Procedure of the World Forum for Harmonization of Vehicle Regulations (WP.29) (TRANS/WP.29/690, ECE/TRANS/WP.29/690/Amend.1 and Amend.2): Belgium, Canada, China, Finland, France, Germany, Hungary, Israel, Italy, Japan, Kuwait, Luxembourg, Netherlands, Norway, Poland, Republic of Korea, Romania, Russian Federation, Saudi Arabia, Spain, Sweden, Switzerland, Turkey and United Kingdom of Great Britain and Northern Ireland (UK). An expert from the European Commission (EC) also participated. Experts from the following non-governmental organizations participated: European Association of Automotive Suppliers (CLEPA), European Liquefied Petroleum Gas Association (AEGPL), International Motorcycle Manufacturers Association (IMMA), International Road Transport Union (IRU), International Organization of Motor Vehicle Manufacturers (OICA), International Organization for Standardization (ISO), International Road Transport Union (IRU), International Association for Natural Gas Vehicles (NGV Global) and the International Association of Public Transport (UITP). Upon the special invitation of the Chair, an expert from the Fédération Internationale de l’Automobile (FIA) and the International Association of the Body and Trailer Building Industry (CLCCR) participated.

2. GRSG considered and adopted the agenda proposed for the 110th session (ECE/TRANS/WP.29/GRSG/2016/1 and Add.1).

GRSG/2016/1 | Provisional agenda for the 110th GRSG session

GRSG/2016/1/Add.1 | Annotated provisional agenda for the 110th GRSG session

3. GRSG also adopted the running order for the session as proposed by the Chair in GRSG-110-01. GRSG noted the main decisions of the World Forum WP.29 taken during its sessions of November 2015 and March 2016 (reports ECE/TRANS/WP.29/1118 and ECE/TRANS/WP.29/1120). GRSG experts expressed their concerns about the cut of a G-post in the vehicle regulations section and underlined the importance of the secretariat services to the World Forum WP.29 and its six subsidiary bodies. GRSG requested the UNECE management to find a quick solution to ensure the proper administration of the three agreements under the responsibility of WP.29.

4. The informal documents distributed during the session are listed in Annex I to this report. The GRSG informal working groups are listed in Annex V of the 110th session report.

5. Recalling the discussion on ECE/TRANS/WP.29/GRSG/2015/21 at the previous GRSG session, the expert from Romania introduced GRSG-110-03 clarifying the requirements on seat spacing and superseding the official document. The expert from OICA introduced GRSG-110-09 amending the provisions on the use of the gaging devices in the case of monitor or display devices mounted at the ceiling of buses and coaches. The expert from Italy presented GRSG-110-21 to align the 05, 06 and 07 series of amendments of UN Regulation No. 107 with the requirements of Supplement 4 to the 04 series of amendments concerning barriers in the gangway and the amount of priority seats in buses and coaches. GRSG adopted the proposals as reproduced in Annex II to the report and requested the secretariat to submit them to WP.29 and AC.1 for consideration at their November 2016 sessions, as draft Supplements to the 04, 05, 06 and 07 series of amendments to UN Regulation No. 107.

GRSG-110-03 | Proposal for amendments to UN Regulation No. 107 Revised approach to resolving the issues raised in Romania's proposal GRSG/2015/21 to redefine the measurement criteria for determining appropriate seat spacing. This proposal has been developed collaboratively by Romania, OICA, and CCLCR with respect to discussions held by the type approval authorities of the member states of the European Union (TAAM). The proposal includes the use of a new testing gauge for the H dimension measurement.

GRSG-110-09 | Proposal for amendments to Series 04 to 07 of Regulation No. 107 Proposal to clarify paragraph 7.7.5.1. with regard to ceiling-mounted displays or monitors and simplify the testing procedure:<ul><li>The gauge shall be used only for the identification of the monitors to be tested.</li><li>The simplified way to apply the removal force corresponds to a passenger pushing the monitor/display with its hand, and in these conditions the acceptable force limit is adapted.</li><li>The test must be conducted in both directions.</li><li>The proposed wording for the last condition to fulfil is more technology neutral, the case of automatic redeployment is also considered and banned.</li></ul>

GRSG-110-21 | Proposal for supplements to the 05, 06 and 07 series of amendments to UN Regulation No. 107 Proposal to extend requirements introduced via Supplement 4 to the 04 series of amendments concerning barriers in the gangway and the amount of priority seats to the 05, the 06 and the 07 series of amendments.

GRSG/2015/21 | Proposal for amendments to the 05 and 06 series of amendments to Regulation No. 107 Proposal to redefine the measurement criteria for determining appropriate seat spacing in order to address observed cases where adequate spacing is not achieved even though the current criteria are fulfilled. The type approval authorities of the member states of the European Union (TAAM) discussed the proper interpretation of the text of the Regulation in the case of seats with a central recess (sunken area) and decided that the text of the Regulation needed to be modified in order to provide an adequate method to measure the H dimension.

6. The expert from Belgium presented ECE/TRANS/WP.29/GRSG/2016/5 proposing to remove the new safety prescriptions for trolleybuses from UN Regulation No. 107 and insert them into UN Regulation No. 100 on electric power trained vehicles. The expert from UK raised concerns about the differences in the scopes of both Regulations and their application to trolleybuses. GRSG noted the comments by the Working Party on Lighting and Light-Signalling (GRE) about possible alignments of UN Regulations Nos. 107 and 116 with UN Regulation No. 10 on electromagnetic-compatibility (GRSG-110-04). The expert from OICA introduced GRSG-110-08-Rev.1 on the applicability of UN Regulation No. 100 versus Annex 12 of UN Regulation No. 107 with respect to electrical safety provisions. The expert from France explained that the origin of the current problem of trolleybuses was linked to the application of the European Union (EU) legislation on whole vehicle type approval. The expert from Japan informed GRSG about the intention of the Chair of GRE to seek the advice of WP.29 on this subject at the forthcoming session in June 2016. The GRSG Chair questioned the need to also involve the experts of the Working Party on Passive Safety (GRSP) in charge of UN Regulation No. 100. A number of experts expressed their preference to keep the electric safety provisions within UN Regulation No. 107. Thus, GRSG agreed that the experts of the Working Parties concerned should work on a simple solution avoiding further burden for public transport operators. The expert from Belgium volunteered to conduct a more detailed analysis on the compatibility or incompatibility of the scopes and technical provisions for trolleybuses of UN Regulations Nos. 10, 100 and 107.

7. GRSG agreed to resume consideration of this subject at its next session in October 2016 awaiting the outcome of the analysis by Belgium. GRSG requested the secretariat to keep ECE/TRANS/WP.29/GRSG/2016/5 on the agenda as a reference document.

GRSG-110-04 | GRE comments regarding UN Regulations Nos. 107 and 121 Communication to GRSG of work within GRE concerning electromagnetic compatibility provisions for trolley buses (UN R10 and UN R107) and on approval of amendments to UN R7, 87, and 48 concerning lighting failure indicators that may impact UN R121 on telltales and indicators.

GRSG-110-08/Rev.1 | Applicability of UN Regulations to trolley buses Presentation of issues raised during discussions of the GRE Task Force on EMC requirements with regard to the application of several UN Regulations to trolley buses depending upon their configuration (e.g., dual-mode operation either connected to overhead cables or in standard bus mode).

GRSG/2016/5 | Proposal for amendment to Regulation No. 107 Proposal to transfer electrical safety provisions for trolleybuses (Annex 12) from UN R107 to UN R100. In 2006, the provisions of UN R36, UN R52, and UN R107 were merged through the 02 series of amendments to UN R107. In 2015, Annex 12 of UN R107 was amended to align additional safety prescriptions for electrical safety of trolleybuses with the corresponding electrical standards. However, UN R100 has evolved beyond its initial focus on battery electric vehicles and currently presents a more appropriate location for maintaining the trolleybus electrical safety provision of Annex 12. For the provisions of Annex 1 – Part 1 – Appendices 1, 2 and 3, where a list of characteristics of a trolleybus was added apart from the special environmental conditions, a reference will be inserted to Annex 6 – Part 1 and Annex 7 of UN Regulation No. 100. A corresponding proposal for amendments will be submitted as an official document to the Working Party on Passive Safety.

8. GRSG noted no new proposal under this item and agreed to remove it from the provisional agenda of the next session.

9. Recalling the purpose of ECE/TRANS/WP.29/GRSG/2015/16 presented at the previous session of GRSG, the expert from FIA reiterated his position on the need to protect odometer equipment against mileage fraud and, therefore, to place the subject in a broader context. He introduced GRSG-110-17 on the current status of the discussion on cybersecurity in the subgroup Autonomous Driving of the WP.29 informal working group on Intelligent Transport Systems (ITS-AD). He proposed to further discuss with OICA experts the security and functional safety specifications of ISO standards 26262 and 15408 on cybersecurity, data protection and remote access to in-vehicle data. The expert from OICA announced his intention to coordinate, in the near future, a common position from his stakeholder and volunteered to report back to GRSG at the forthcoming session.

10. The GRSG Chair suggested resuming consideration of this subject at the next session of GRSG and invited the expert from FIA to get in contact with OICA.

GRSG-110-17 | Protection against mileage fraud - Current status in ITS-AD Presentation on cybersecurity issues and ISO 26262 (functional safety of electronic systems).

GRSG/2015/15 | Proposal for draft 01 series of amendments to Regulation No. 39 Proposal to insert performance requirements for the installation of odometers on vehicles.

11. The expert from EC recalled the discussion of GRSG at its previous session on GRSG-109-13 proposing to amend the requirements for numeric displays of speedometers. The expert from France underlined the need to also indicate on the speedometer the corresponding speed units. The expert from OICA volunteered to prepare, together with the expert from EU, a joint proposal for consideration at the next GRSG session. The expert from IMMA reminded GRSG that some vehicles of category L should be added.

12. GRSG agreed to resume consideration of this subject at its next session on the basis of an official document to be jointly prepared by the experts from EC, IMMA and OICA taking into account the comments received.

GRSG-109-13 | Proposal for amendments to the 01 series of amendments to Regulation No. 39 Proposal to allow for the approval of speedometers and odometers that display figures either in km/h or mph (but not both simultaneously) provided that the driver is enabled to select between the metric or imperial measurement display modes.

13. The expert from CLEPA withdrew ECE/TRANS/WP.29/GRSG/2015/3.

GRSG/2015/3 | Proposal for amendments to Regulation No. 43 Proposal to define a reduced vision zone I for vehicles of categories M and N other than M₁.

14. The expert from Hungary introduced ECE/TRANS/WP.29/GRSG/2015/22 clarifying the technical requirements on the abrasion test machine. The expert from Germany informed GRSG about the status of work in ISO on abrasion test machines. He expected that the corresponding ISO standard would hopefully be published by the end of 2016. GRSG agreed to resume consideration of ECE/TRANS/WP.29/GRSG/2015/22 at its next session in October 2016, awaiting the publication of the ISO standard.

GRSG/2015/22 | Proposal for amendments to Regulation No. 43 Proposal to clarify the specification of the abrasion test machine.

15. The expert from the Russian Federation introduced ECE/TRANS/WP.29/GRSG/2016/12 proposing to correct editorial errors in the Russian version of UN Regulation No. 46. GRSG adopted the proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2016 sessions, as Corrigenda to the 03 and 04 series of amendments to UN Regulation No. 46.

GRSG/2016/12 | Proposal for the 04 series of amendments to Regulation No. 46 (Russian only) Proposal to harmonize the Russian text with the English-language version of the regulation.

16. The expert from Germany proposed to also correct the provisions of paragraph 6.2.1.2. on the latency of devices for indirect vision with those of paragraph 6.2.2.3.4.3. on camera monitor systems (GRSG-110-28). GRSG endorsed the proposed text as reproduced below:

Paragraph 6.2.1.2., amend to read:
“6.2.1.2. If a device for indirect vision …… the total process of scanning, rendering and reset to its initial position together shall not take more than 200 milliseconds at room temperature of 22 °C ±5 °C.”

17. The secretariat was requested to submit it to WP.29 and AC.1 for consideration at their November 2016 sessions, as draft Supplement 4 to the 04 series of amendments to UN Regulation No. 46, subject to a final review by GRSG at its next session in October 2016.

GRSG-110-28 | Proposal for a supplement to the 04 series of amendments to Regulation No. 46 Proposal to change the latency for scanning a field of vision (total process of scanning, rendering and reset to its initial position) from a maximum of 2 seconds to a maximum of 200 ms. This proposal corresponds to the current state of technology and removes a contradiction within the regulation between paragraphs 6.2.1.2. and 6.2.2.3.4.3. (the latter introduced via supplement 2 to the 04 series of amendments).

18. On behalf of the Task Force (TF) on UN Regulation No. 46, the expert from Japan reported on the progress made by the group during the recent meeting held prior to the GRSG session. He gave a presentation on detailed results of a national study on fatal accidents of pedestrians with motor vehicles at low speed (GRSG-110-10). He invited GRSG experts to provide the results of similar studies in their country, if available. He concluded that a possible solution to avoid such accidents could be new requirements to ensure the driver’s view on the proximity area of the front and rear surroundings of the vehicle (GRSG-110-11). He referred to GRSG-110-12 proposing a first set of amendments to UN Regulation No. 46. GRSG welcomed the detailed information from Japan.

GRSG-110-10 | Study of pedestrian fatal accidents (vs. motor vehicles at low speed) in Japan Presentation of data to supplement discussions on improvements to the driver field of view, especially with respect to indirect vision (rear, blind spot, mirrors, camera systems).

GRSG-110-11 | Requirement for the view of the vehicle's surroundings and rear Proposal for improvements to the driver rear field-of-view requirements towards reducing pedestrian accidents.

GRSG-110-12 | Proposal for amendments to Regulation No. 46 Proposal to introduce new requirements and test procedures for rear-view systems in order to reduce risks of pedestrian collisions while vehicles move in reverse.

19. The expert from Germany reported on some investigations in his country on such accident types and expressed his preference to address this problem through a driver warning system, such as the driver assist systems so as to avoid blind spot accidents referred to in item 22 (see paras. 60-61 below), instead of a close-proximity and rear-view device proposed in GRSG-110-12. The expert from UK informed GRSG about a study of his department on the detection of vulnerable road users by vehicle sensors. He underlined that there was still a challenge to give the driver enough time for reaction to avoid a collision. The expert from Canada reported on some investigations in his country during the last five years on accidents of heavy goods vehicles with pedestrians or cyclists and expressed his full support to the GRSG activities on this subject. The expert from France endorsed the comments received and expressed his preference for a detection and driver warning system. Taking a broader view on the discussion, the expert from OICA stated that the Working Party on Brakes and Running Gears (GRRF) had already detailed considerations of obstacle detection systems when developing provisions for UN Regulation No. 131 on Advanced Emergency Brake Systems (AEBS).

GRSG-110-12 | Proposal for amendments to Regulation No. 46 Proposal to introduce new requirements and test procedures for rear-view systems in order to reduce risks of pedestrian collisions while vehicles move in reverse.

20. Following the discussion, GRSG recommended the TF to go forward stepwise and to resume discussion on this subject in a broader view for light- and heavy-duty vehicles. Thus, the Chair of GRSG invited all experts to participate in the activities of the TF and to provide detailed data on accidents of such vehicles with pedestrians and cyclists in their country. GRSG agreed to resume consideration at its next session and to keep GRSG-110-12 on the agenda as a reference document.

21. The expert from Poland informed GRSG about the purpose of ECE/TRANS/WP.29/GRSG/2016/4, proposing to insert into UN Regulation No. 55 an amendment imposing a new general constraint for granting component type-approval for mechanical coupling devices dedicated to category M1 vehicles only if they were designed to tow trailers. He announced the submission of the document to GRRF for consideration at its next session in September. GRSG endorsed that position and agreed to remove the agenda item.

GRSG/2016/4 | Proposal for amendment to Regulation No. 55 At the May 2015 Type Approval Authorities Meeting (TAAM), Poland raised concerns (attached with this submission) over small M₁ vehicles being equipped with aftermarket coupling devices where the vehicle in question is not designed for towing a trailer. In effect, these vehicles are not permitted to tow trailers, but are nonetheless enabled to be equipped for such a purpose by the aftermarket devices. Therefore, Poland proposes to amend UN R55 to ensure that coupling devices are only approved for use on vehicles approved for towing trailers.

22. Recalling its decision at the previous session, GRSG reviewed the proposal by IMMA on the identification of controls, tell-tales and indicators on two-wheeled motorcycles and mopeds. GRSG reconfirmed the adoption of the proposed amendments to UN Regulation No. 60 as reproduced in ECE/TRANS/WP.29/2016/27 and its submission to WP.29 and AC.1 for consideration at their forthcoming sessions in June 2016.

WP.29/2016/27 | Proposal for Supplement 5 to Regulation No. 60 Proposal to allow for small variations in the presentation of motorcycle telltales and control symbols.

23. The expert from OICA introduced ECE/TRANS/WP.29/GRSG/2016/11 proposing to amend the provisions of UN Regulation No. 66 with respect to intrusion into residual space during the roll over test. The expert from UK presented GRSG-110-16 suggesting an alternative text.

24. GRSG endorsed in general the proposal but noted concerns about the wordings “no risk of contact”. GRSG invited the experts from UK and OICA to review the proposed text and agreed to resume consideration of ECE/TRANS/WP.29/GRSG/2016/11 at its next session and to keep both documents on the agenda as reference documents.

GRSG-110-16 | Proposal for the 02 series of amendments to Regulation No. 66 Proposal to specify that "handrails and handholds at doorways where the associated residual space is not designated for passengers positioned for travel, and where intrusion into the space presents no risk of contact with passengers, shall also be ignored."

GRSG/2016/11 | Proposal for the 02 series of amendments to Regulation No. 66 Proposal to define an exemption for handles from "residual/survival space" intrusion requirements for vehicle spaces not intended for occupants. Handles and handholds used to assist passengers in entering and exiting a bus are located outside of passenger seating and standing areas where OICA argues that they do not present a danger; however, the current rollover testing provisions could result in their inclusion in the area defined as "residual/survival space" where any intrusion is prohibited.

25. The expert from AEGPL introduced GRSG-110-13, superseding his proposal ECE/TRANS/WP.29/GRSG/2015/35 and proposing new provisions to prevent a flow of liquefied petroleum gas (LPG) into the petrol or diesel tank, and vice versa. GRSG noted general support on the updated proposal. Following a study reservation by the expert from France, GRSG decided to have a final review of the proposal at its next session in October 2016 and requested the secretariat to circulate GRSG-110-13 with an official symbol.

GRSG-110-13 | Proposal for amendments to the 01 series of amendments to Regulation No. 67 Proposal to insert new safety provisions with regard to LPG systems having hydraulic interconnections with the petrol or diesel fueling system through which inter-flows of fuels may occur.

GRSG/2015/35 | Proposal for amendments to the 01 series of amendments to Regulation No. 67 Proposal to amend UN R67 to allow for limited flows of petrol into the LPG tank of dual fuel vehicles.

26. Recalling the purpose of ECE/TRANS/WP.29/GRSG/2016/7, the expert from the Netherlands presented GRSG-110-25 amending the provisions of UN Regulation No. 67 on LPG vehicles to allow Class 0/I hoses with couplings using gas tubes other than seamless material. GRSG noted a number of comments on the need for detailed testing specifications for type approval purposes and for clarification of the responsibilities. The Chair of GRSG invited all experts to send their written comments to the expert from the Netherlands. GRSG agreed to resume consideration of this subject at its next session in October 2016 on the basis of an updated official document by the Netherlands taking into account the comments received.

GRSG-110-25 | Proposal for amendments to Regulation No. 67 Proposal of corrections to document GRSG/2016/7. The wording of the original proposal opens the possible interpretation that the regulation allows materials other than copper, stainless steel, or steel with corrosion-resistant coatings for gas tubes. The intention of the proposal was only to allow for "non-seamless" gas tubing. The original proposal is therefore modified to allow Class 0/I hoses with couplings using gas tubes of other than seamless material.

GRSG/2016/7 | Proposal for amendments to Regulation No. 67 Proposal to allow the use of Class 0 hoses with couplings using sealing technologies other than those with a 45° cone. Currently, non-seamless double and single wall tubes are used in brake and fuel tubing applications, allowing for the use of a variety of end forms and coupling techniques. Provided the tubing can withstand the applicable tests according to Annex 15, Table 1, such configurations should be permitted under UN R67 in order to remove an unwarranted design restriction.

27. The expert from UK reminded GRSG about the purpose of document ECE/TRANS/WP.29/GRSG/2016/2 (based on GRSG-109-17) amending the scope of the Regulation to ensure that as many vehicles as possible were fitted with a lateral protection device. The expert from CLCCR supported the proposal in principle, but preferred to insert derogations for some niche products (GRSG-110-20-Rev.1). GRSG noted a number of comments.

28. GRSG agreed to resume consideration of this subject at its next session and requested the secretariat to keep ECE/TRANS/WP.29/GRSG/2016/2 and GRSG-110-20-Rev.1 on the agenda as reference documents. Thus, the expert from UK volunteered to prepare a revised document for a final review at the forthcoming GRSG session, taking into account the comments received.

GRSG-110-20/Rev.1 | Revised proposal for amendments to Regulation No. 73 Updated proposal, revised for clarity, to amend document GRSG/2016/2 by replacing paragraph 1.2.2. rather than deleting it. Drawing from the recently approved amendment to UN R58 (document GRSG/2015/17), this proposal would amend paragraph 1.2.2. to read, “Vehicles where any LDP (e.g. fixed, removable, foldable, adjustable, etc.) is incompatible with their on-road use may be partly or fully exempted from this Regulation, subject to the decision of the Type Approval Authority.”

GRSG/2016/2 | Proposal for amendments to Regulation No. 73 Proposal to expand the scope of the regulation by deleting paragraph 1.2.2. which allows for the exclusion of “vehicles designed and constructed for special purposes where it is not possible, for practical reasons, to fit lateral protection devices” from the text. The UK submits that paragraphs 13 and 16 of the regulation provide specific provisions that address this situation whereas the exclusion clause allows for a broader interpretation that unnecessarily limits the use of lateral protection devices. Moreover, exemptions may still be accorded at the national level.

29. GRSG noted ECE/TRANS/WP.29/GRSG/2016/13 (tabled by the secretariat) to align the provisions of UN Regulation No. 105 with those of the new 2017 edition of the European Agreement concerning the International Carriage of Dangerous Goods by Road (ADR). The expert from the Netherlands presented GRSG-110-07 proposing some further corrections to ECE/TRANS/WP.29/GRSG/2016/13.

30. GRSG adopted the proposal as reproduced in Annex III to this report and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2016 sessions, as draft 06 series of amendments to UN Regulation No. 105, subject to a final review by the Working Party on the Transport of Dangerous Goods (WP.15) at its May 2016 session and GRSG at its next session in October 2016. (Note by the secretariat: WP.15 endorsed the proposed amendments.)

GRSG-110-07 | Draft Corrigendum to ECE/TRANS/WP.29/2106/13 Proposed corrections to the original proposal to align UN R105 with ADR 2017.

GRSG/2016/13 | Proposal for the 06 series of amendments to Regulation No. 105 Proposal prepared by the UNECE secretariat to align the provisions of UN Regulation No. 105 with those of the new 2017 edition of the European Agreement concerning the International Carriage of Dangerous Goods by Road (ADR).

31. The expert from OICA recalled the discussion at the previous GRSG session on ECE/TRANS/WP.29/GRSG/2015/36 proposing to amend the provisions of UN Regulation No. 67 to allow the installation of autonomous CNG heaters for the heating of the engine. The expert from Germany presented GRSG-110-27 further clarifying the text of paragraph 18.5.1.3.

32. GRSG adopted the proposal as reproduced below and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2016 sessions, as draft Supplement 5 to the 01 series of amendments to UN Regulation No. 110.

Paragraph 18.5.1.3., amend to read:
“18.5.1.3. Notwithstanding the provisions of paragraph 18.5.1.2.
(a) the automatic cylinder valve may stay in an open position during commanded stop phases, and
(b) in the case where a fire alarm system is installed in the compartment where a CNG combustion heater is located, the automatic cylinder valve(s) may be opened by an electronic control unit for the purpose of permitting its operation to warm the engine coolant.”

GRSG-110-27 | Proposal for amendments to Regulation No. 110 Proposal to amend GRSG/2015/36 introducing requirements for the operation of a CNG heater when the vehicle is stationary and before starting the engine. The limitation on the number of valves used to operate the CNG combustion heater will require technical changes without any significant benefit. The proposal therefore deletes the limitation and introduces additional clarifications.

GRSG/2015/36 | Proposal for amendments to Regulation No. 110 Proposal to enable the use of autonomous CNG heaters for the heating of engines before the vehicle is in service.

33. Reminding GRSG experts about the purpose of ECE/TRANS/WP.29/GRSG/2016/6, the expert from ISO introduced GRSG-110-05 proposing further amendments to UN Regulation No. 110 aimed at harmonizing the requirements for CNG cylinders with those of standard ISO 11439:2013. GRSG welcomed the work done by ISO. GRSG noted a number of study reservations and the request for a detailed justification of only referencing to ISO standards instead of reproducing the testing provisions. Following the recommendation by WP.29, GRSG underlined the need to have a static referencing of the international standards referred to in the proposal. A number of experts requested to have free access to these standards. The secretariat offered the possibility to make a copy of these standards available on the GRSG website, but protected by a password which will be circulated to the GRSG experts prior to the forthcoming GRSG session.

34. Following the discussion, the expert from ISO announced his intention to provide the secretariat with a copy of the most important standards referenced to in his proposal. He volunteered to submit in due time a revised official document for amending UN Regulation No. 110, taking into account the comments received.

GRSG-110-05 | Proposal for amendments to Regulation No. 110 Proposal to align the CNG cylinder requirements in Regulation No. 110 with requirements in ISO 11439: 2013.

GRSG/2016/6 | Proposal for amendments to Regulation No. 110 Proposal to harmonize UN R110 with standard ISO 11439:2013 on high pressure cylinders for the on-board storage of natural gas as a fuel for automotive vehicles.

35. The expert from the Netherlands introduced GRSG-110-26 (superseding ECE/TRANS/WP.29/GRSG/2016/8) proposing an amendment to UN Regulation No. 110 to allow Class 0 hoses with couplings using sealing technologies other than those with a 45° cone and, thus, to avoid design restrictive requirements. The proposal received a number of comments.

36. GRSG adopted the proposal as reproduced below and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2016 sessions, as part (see para. 32 above) of draft Supplement 5 to the 01 series of amendments to UN Regulation No. 110.

Annex 4B, paragraph 1.6.2.2., amend to read:

“1.6.2.2. The interface type for the hose coupling shall be:

(a) sealing cone of swivel-nut type of the type with a half vertical angle of 45°, or
(b) other couplings complying with the tests described in paragraph 1.7., as well as the tests mentioned in Annexes 5A and 5B.

In the case of an interface type using a soft seal body (e.g. O-ring), the type of material chosen shall be tested in accordance with Annexes 5D, 5F and 5G.

Couplings shall have complementary counterparts."

GRSG-110-26 | Proposal for amendments to Regulation No. 110 Editorial amendment to document GRSG/2016/8 for clarity. The original proposal would allow the use of Class 0 hoses with couplings using sealing technologies other than those with a 45° cone provided that the hose assembly can withstand the impulse test of paragraph 1.7. and the tests of Annexes 5A (overpressure test) and 5B (external leakage test). This proposal clarifies that the original sealing-cone specification or other compliant couplings, including designs with soft seals (e.g., O-ring) provided they pass testing described in Annexes 5D, 5F, and 5G.

GRSG/2016/8 | Proposal for amendments to Regulation No. 110 Proposal to allow the use of Class 0 hoses with couplings using sealing technologies other than those with a 45° cone. Currently, non-seamless double and single wall tubes are used in brake and fuel tubing applications, allowing for the use of a variety of end forms and coupling techniques. Provided the hose assembly can withstand the impulse test of paragraph 1.7. and the tests of Annexes 5A (overpressure test) and 5B (external leakage test), such configurations should be permitted under UN R67 in order to remove an unwarranted design restriction. In cases where a soft seal body (e.g. O-ring) is used, the compatibility of the material with use conditions must be demonstrated by testing according to Annexes 5D (CNG/LNG compatibility test), Annex 5F (resistance to dry heat) and Annex 5G (ozone aging).

37. The expert from the Netherlands presented ECE/TRANS/WP.29/GRSG/2016/9 aimed at correcting a typographical error and clarifying the current provisions of the Regulation. He also introduced ECE/TRANS/WP.29/GRSG/2016/10 proposing to insert provisions for LNG fuel connector as specified in ISO 12617:2015. Both documents received a number of comments. The expert from France raised a study reservation on the reference to the ISO standard in paragraph 2.2. of Annex 4J. Following the discussion, GRSG adopted both proposal as reproduced below and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2016 sessions, as part (see paras. 32 and 36 above) of draft Supplement 5 to the 01 series of amendments to UN Regulation No. 110:

Paragraph 7.1., correct “paragraphs 8.12. to 8.21.” to read “paragraphs 8.12. to 8.22.”.

Annex 4A, paragraph 4.2.4., correct “of Class 1 and Class 2” to read “of Class 2”.

Annex 4H, paragraph 2.2., correct “than 5 seconds” to read “than 2 seconds”.

Annex 4J
Paragraph 2.2., shall be deleted.

Paragraph 3.1.6., correct “shall be not be” to read “shall not be”.

Insert new paragraphs 4. and 4.1., to read:
“4. LNG filling receptacle dimensions
4.1. Figure 1 shows the dimensions of the LNG filling receptacle.

"

38. GRSG agreed to resume consideration at the next session of GRSG on the ISO reference on the basis of a revised proposal jointly prepared by the Netherlands and NGV Global, taking into account the comments received.

GRSG/2016/10 | Proposal for amendments to Regulation No. 110 Proposal to include the liquefied natural gas (LNG) fuel connector provisions as specified in ISO 12617:2015.

GRSG/2016/9 | Proposal for amendments to Regulation No. 110 Proposal to correct a typographical error in paragraph 7.1. where the reference should be to paragraph 8.22 rather than 8.21, to remove a duplicate and contradictory reference in Annex 4A to the requirements of Class 1 pressure relief valves, and to align paragraph 2.2. of Annex 4H with paragraph 18.6.1.2. limiting the delay in switching-off of the automatic valve after stalling of the engine to two seconds (rather than five as presently in the text).

39. The expert from France presented GRSG-110-23 introducing new provisions for the use of natural gas refrigeration systems to vehicles propelled by natural gas (CNG or LNG). GRSG noted general support on the proposal and agreed to resume consideration of this subject at its next session in October 2016. For that purpose, the secretariat was requested to circulate GRSG-110-23 with an official symbol.

GRSG-110-23 | Proposal for amendments to Regulation No. 110 Proposal to allow for the use of natural gas refrigeration systems to vehicles propelled by natural gas (CNG or LNG). This proposal addresses a new, environmentally friendly natural gas fuelled refrigeration system for trucks with refrigerated loads that already are propelled by natural gas. Currently paragraph 18.1.7.1 allows heating systems to be fitted on vehicles to heat the passenger compartment and/or the load area of a vehicle, however, the same provision omits cooling systems that are used on trucks for the carriage of loads requiring refrigeration.

40. Recalling the purpose of ECE/TRANS/WP.29/GRSG/2015/7, the expert from OICA informed GRSG that there was no new information on this subject. He suggested resuming consideration of this subject at the next session of GRSG and volunteered to prepare a revised document. GRSG endorsed that suggestion and agreed to keep document ECE/TRANS/WP.29/GRSG/2015/7 on the agenda as a reference document.

GRSG/2015/7 | Proposal for draft amendments to Regulation No. 116 UN R116 specifies operating voltages and voltage limits. Current technology and intelligent battery management systems allow for precise control and definition of these parameters. This includes “intelligent” operating ranges in order to optimize energy management (CO2 emission reduction). Fixed operating voltage ranges are therefore unnecessary or even may hinder efforts for CO2 emission reduction in the future. This proposal would allow varying operating voltage ranges according to the battery technology used to remove this restriction impact such advanced designs.

41. GRSG reconsidered GRSG-107-08 on the possible use of innovative system which enable opening of a vehicle via smartphone and on the question if a silent alarm to a security service via the internet might be subject to type approved system. The expert from OICA clarified that experts should differentiate between immobilizers and door locking systems. Following the discussion, GRSG endorsed the position of Germany that, according to the current definition of “key” in the provisions of UN Regulation No. 116, such systems could not yet be type approved. It was agreed that, in the case of evidence of the need to allow the use of such innovative systems for the purpose of activation or deactivation of immobilizers and door locking systems on vehicles, UN Regulation No. 116 would have to be amended first.

GRSG-106-38 | UN Regulation No. 116 and innovative vehicle alarm systems/ anti-theft systems European Commission request for input on the possible type approval of new systems that enable unlocking cars via smart phones and that send silent alarms to security services via the Internet.

GRSG-107-08 | UN Regulation No. 116 and innovative vehicle alarm systems/anti‐theft systems Input from Germany in response to the European Commission request (document GRSG-106-38) for input on the possible type approval of new systems that enable unlocking cars via smart phones and that send silent alarms to security services via the Internet.

42. Recalling the discussion on this subject at the previous GRSG session, the expert from Germany introduced ECE/TRANS/WP.29/GRSG/2016/3 proposing updated test requirements for electric cables sleeves and cable conduits. The expert from Finland suggested amending also the test provisions of Annex 8 on the test apparatus and the sample dimensions (GRSG-110-02).

43. Following the discussion, GRSG could not give full consent to the proposals and agreed to have a final review of the proposals at the next session of GRSG. Thus, the secretariat was requested to keep both documents on the agenda unless a revised proposal would be submitted.

GRSG-110-02 | Proposal for Supplement 3 to the 02 series of amendments and Supplement 1 to the 03 series of amendments to Regulation No. 118 Proposal to delete the volume and shape limits of the fume cupboard described in Annex 8 (Test to determine the vertical burning rate of materials) and replace these with the performance specification that the fume cupboard dimensions shall not affect the test results. The proposal also sets a minimum sample size of 375 x 170 mm under paragraph 3.1. of Annex 8.

GRSG/2016/3 | Proposal for the 03 series of amendments to Regulation No. 118 Proposal to clarify the scope and the application of the regulation. The proposal clarifies that the regulation applies to “the burning behaviour of electric cables and cable sleeves or cable conduits used in the vehicle” and it updates the reference to paragraph 5.22. of ISO 6722-1:2011. Specifically, the proposal would apply testing to electric cables, cable sleeves, and cable conduits that exceed a length of 100 mm.

44. The expert from the Russian Federation recalled that the purpose of documents ECE/TRANS/WP.29/GRSG/2015/24 and GRSG-110-14 was to insert into UN Regulation No. 121 a new symbol for the emergency call control and tell-tale. The proposal received the full support of GRSG. However, it was agreed to submit it in parallel with the new draft Regulation on AECS (para. 47 below). Thus, GRSG preferred to keep the document on the agenda and requested the secretariat to circulate GRSG-110-14 with an official symbol.

GRSG-110-14 | Proposal to amend ECE/TRANS/WP.29/GRSG/2015/24 Proposal to add a telltale and symbols for “Accident Emergency Call System (AECS)”.

GRSG/2015/24 | Proposal for amendments to Regulation No. 121 Proposal to add a telltale and symbols for “Accident Emergency Call System (AECS)”.

45. GRSG noted the outcome of the recent session of GRE (GRSG-110-04) and the request to align UN Regulation No. 121. In this respect, the expert from Italy presented GRSG-110-06 aimed at clarifying the provisions of UN Regulation No. 121 with respect to the indication of the failure of a light source.

46. GRSG adopted the proposal as reproduced in Annex IV to this report and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2016 sessions, as draft Supplement 9 to the original version of UN Regulation No. 121 and as draft Supplement 1 to the 01 series of amendments to UN Regulation No. 121.

GRSG-110-04 | GRE comments regarding UN Regulations Nos. 107 and 121 Communication to GRSG of work within GRE concerning electromagnetic compatibility provisions for trolley buses (UN R10 and UN R107) and on approval of amendments to UN R7, 87, and 48 concerning lighting failure indicators that may impact UN R121 on telltales and indicators.

GRSG-110-06 | Draft proposal for Supplement 1 to the 01 series of amendments to UN Regulation No. 121 Proposal to enable the use of alternate colors (per footnote 18 of Table 1 and in line with ISO Standard 2575) for certain lighting tell-tales in order to indicate light source failures in response to the proposals for light failure indicators under UN Regulations Nos. 7, 48 and 87 (GRE/2016/7, GRE/2016/12 and GRE/2016/17) as adopted by GRE. This proposal anticipates use of the same approach in response to plans for additional failure indication requirements for other lighting regulations.

47. The expert from the Russian Federation, chairing the IWG on AECS, reported on the progress of work made by the group (GRSG-110-22). He drew the attention of GRSG to the controversial discussion of the experts on the performance requirements in the case of testing the resistance of accident emergency call devices to mechanical impact (pulse test). He presented the new draft UN Regulation on AECS (GRSG-110-15) and stated that this proposal was not yet the final version. He informed GRSG about the group’s decision to go forward in a two-step approach and announced the intention of the IWG to finalize the basic proposal by mid-July 2016 for submission to and adoption by GRSG at its next session in October 2016 on the basis of an official document.

48. GRSG welcomed the proposal submitted by the IWG. The expert from EC informed GRSG that the EU legislation on emergency call systems (eCall) had been based on an acceleration/deceleration of 65g. The expert from the Netherlands underlined the importance of AECS as a vehicle safety feature and the need to ensure their functionality in case of severe crashes. Thus, he expressed his preference to align the performance requirements of draft UN Regulation on AECS with those of the EU regulation. The experts from Japan and the Russian Federation raised their concern about the considerable costs of test equipment performing such acceleration/declaration of 65g. They were of the opinion that GRSG should take into account the economic burden for technical services. As a compromise solution, the expert from OICA suggested going forward in a two-step approach and adopting the new UN Regulation with the 60g value and subsequently to adopt the more stringent performance value of 65g as new series of amendments to the Regulation. The expert from CLEPA endorsed that position.

49. As GRSG could not find an agreement on this subject, the Chair of GRSG invited all experts to check on their national level the feasibility and durability of the 65g pulse test equipment and to send their comments including justifications on GRSG-110-15 at the latest by the end of June 2016 to the Secretary/Chair of the IWG. He also invited the experts from the EC, Japan and the Russian Federation to find compromise agreement on the performance value for the pulse test considering the real benefit in life savings between the two pulses. GRSG endorsed that suggestion and agreed to resume discussion at the forthcoming session of GRSG on the basis of an official document.

GRSG-110-15 | Draft new regulation on uniform provisions concerning the approval of Accident Emergency Call Devices (AECD), vehicles with regard to the installation of an AECD of an approved type and vehicles with regard to their AECS Working draft prepared by the Informal Working Group on AECS as a discussion document for GRSG.

GRSG-110-22 | Progress report of GRSG informal group on Accident Emergency Call Systems

50. The expert from OICA, in his capacity of GRSG Ambassador to the IWG on IWVTA, informed GRSG about the progress made during the recent meetings of the IWGs (WP.29-168-12). As an outcome of the task force set up by GRSG at the previous session, he introduced GRSG-110-24 proposing several solutions to clarify the scope of UN Regulation No. 116. GRSG welcomed the document and noted a number of comments.

51. Following the discussion, GRSG agreed to follow the idea of having in future three separate UN Regulations on (i) anti-theft devices, (ii) alarm systems and (iii) immobilizers. GRSG agreed to resume consideration of this subject at its next session in October 2016 on the basis of concrete proposals and requested the secretariat to keep GRSG-110-24 on the agenda as a reference document.

GRSG-110-24 | Proposal for amendments to Regulation No. 116 Proposal from the informal working group on the International Whole Vehicle Type Approval to restructure UN R116 into two separate regulations. The regulation addresses anti-theft, alarm, and immobilizer aspects of theft prevention. Since these aspects may be mandatory or optional depending upon the country or market, the application of UN R116 to whole vehicle type approval becomes problematic. This proposal would extract the immobilizer provisions into a separate new regulation.

52. Recalling the purpose of ECE/TRANS/WP.29/GRSG/2015/30, the expert from IMMA announced his intention to submit, for consideration at the forthcoming GRSG session, a revised proposal on a definition of “twinned wheels”, taking into account the comments received by the members of his organization.

53. GRSG welcomed the information and agreed to resume consideration of this subject at its next session in October 2016 on the basis of an updated official document by IMMA.

GRSG/2015/30 | Proposal for amendments to the Consolidated Resolution on the Construction of Vehicles Proposal to introduce a definition for "twinned wheels".

54. Recalling the discussion on this subject at the previous GRSG session, the expert from UK reported that the IWG on Intelligent Transport Systems (ITS) and specifically its subgroup on Automated Driving (ITS/AD) had not yet discussed in detail the need to develop a new Regulation on the optional installation on vehicles of Event Data Recorder (EDR) taking into account technical parameters to be stored as well as the access and security of the data. The expert from Germany informed GRSG that the GRRF IWG on Automatically Commanded Steering Function (ACSF) had a preliminary discussion on the need of installation on automated vehicle of the so-called Data Storage System for ACSF (DSSA). The expert from OICA added that ACSF was currently considering the type of data necessary to be recorded and/or stored. He recommended distinguishing the data collected in the existing “regular” EDR, the data collected and sent out for AECS and those to be collected in the framework of ACSF.

55. GRSG reiterated its position to seek the advice of WP.29 on how to go forward with the coordination of the activities on data recording and data protection within the Working Parties subsidiary to WP.29 and their IWGs involved in automated driving, steering functions and emergency call systems. The Chair of GRSG announced his intention to seek the advice of WP.29 on this subject at the June 2016 session.

56. The expert from UK offered his commitment to prepare for the next GRSG session a proposal on a possible way forward, taking into account the advice of WP.29. GRSG welcomed that offer and agreed to resume consideration of this subject at its next session.

57. The expert from the Republic of Korea, chairing the IWG on Panoramic Sunroof Glazing (PSG), reported on the outcome of the fourth meeting held in Geneva prior to the GRSG session on 25 April 2016. He added that the IWG had decided to stop its research activities and had considered a first proposal for the limitation of ceramic printed areas. He announced the intention of the IWG to convene again in Gilching (Germany) on 28 June 2016 to finalize the proposal for amendments to the UN regulations on safety glazing.

58. GRSG welcomed the good progress of work done by the IWG and agreed to resume consideration of this subject at the next GRSG session on the basis of a concrete proposal for amendments to be submitted by the IWG.

59. The expert from Germany informed GRSG about outcome of the recent negotiations with the Society of Automotive Engineers (SAE) to obtain detailed drawings and technical specifications referred to in UN regulations. He added that he had already reported to WP.29 at the November 2015 session (see report ECE/TRANS/WP.29/1118, para. 42). GRSG welcomed the information and agreed to remove this item from the agenda.

60. The expert from Israel gave a presentation (GRSG-110-19) on the need and global support to develop new technical provisions for blind spot detection and warning systems as well as the installation of such collision avoidance systems on heavy duty vehicles. Referring to GRSG-109-19 presented at the previous session, the expert from Germany introduced GRSG-110-18-Rev.1 on the current status of development on test procedures for a new draft regulation on Advanced Driver Assist Systems (ADAS) to avoid such blind spot accidents through a driver information and warning system. He reported on the results of several test scenarios of a heavy goods vehicle with a proposed test dummy. He concluded that further investigations were still in progress. GRSG welcomed the presentations and noted a number of comments.

61. Following the discussion, GRSG decided to go forward in a two-step approach: (i) to develop new requirements for driver warning systems and (ii) to investigate subsequently the possibility to develop further requirements for automatic braking systems. GRSG agreed to resume consideration of this subject at its next session on the basis of first draft of the new UN Regulation on ADAS expected to be submitted by Germany.

GRSG-109-19 | Information on requirements for driver assistance systems for heavy goods vehicles addressing blind spot accidents Information on BASt research into heavy vehicle accidents and fatalities involving cyclists. Germany intends to propose the mandatory installation of blind-spot detection systems for such vehicles.

GRSG-110-18/Rev.1 | Draft Regulation on driver assist systems to avoid blind spot accidents Presentation on blind-spot accident data and work on the development of a test cycle to assess the effectiveness of blind-spot countermeasures to reduce the risk of VRU collisions.

GRSG-110-19 | VRU collision avoidance and blind-spot detection

62. Referring to the decision of WP.29 at its March 2016 session (ECE/TRANS/WP.29/1120, para. 38), the Secretary of GRRF reported on a discussion that took place at GRRF in the context of IWVTA (WP.29-168-15) and on the issue of the performance of automotive systems (e.g. Tyre Pressure Monitoring Systems) in conditions other than those tested according to the regulated test procedures. He added that some safety systems, especially those relying on software, could be designed to only work in limited conditions corresponding to those tested rather than in all the relevant driving conditions.

63. GRSG noted the information and agreed on the need to discuss in the Working Parties subsidiary to the World Forum the possible risks of such systems. However, GRSG was of the opinion that type approval authorities should rely on the test provisions of the UN Regulations in force and should not perform a “fishing expedition” during the type approval procedure.

WP.29-168-15 | The performance of automotive systems in conditions other than those tested in the framework of type-approval or self-certification Brief summary of GRRF discussions related to the performance of products in conditions outside the scope of test procedures (i.e., assuring satisfactory performance under all normal road conditions). GRRF agreed with Russia that this issue should be put before the full World Forum.

64. The secretariat informed GRSG about the notice of proposed rulemaking in the United States of America on the safety of buses and coaches initiated the National Highway Traffic Safety Administration.

65. GRSG welcomed the information and noted that more detailed information was available on the NHTSA website.

66. Learning that Dr. Klaus Preusser (Germany) was retiring, GRSG thanked him for his considerable contributions over the last decades to the activities of GRSG and especially his dedication, since 2011, as Chair of the GRSG IWG on Plastic Glazing.

67. GRSG noted that Mr. Louis-Sylvain Ayral (CLEPA) also decided to retire and no longer attend the sessions. GRSG acknowledged his continued support during all the years of participation in the sessions. GRSG recognized their commitments with a long applause and wished both of them a long and happy retirement.
