Working draft of the regulation pursuant to the 11th AECS informal group session.

Proposal as prepared by the UN R55 informal group and approved by the GRRF to update UN R55 with respect to:
a) Requirements on remote indication;
b) Availability of information on coupling fixing points for A50X couplings;
c) On lateral strength of drawbars; and
d) a new class definition for fully automatic drawbar couplings.

Proposal to correct an oversight by aligning the “alternative procedures” provisions of the regulation with the previously adopted amendment of the regulation that raised the rear-impact speed to between 48 and 52 km/h (03 series of amendments).

Proposal to clarify that fully integrated surveillance mirrors may be mounted below 2 metres in cases where they are integrated in a housing including one or more Class II or III mirrors.

Proposal to

• extend requirements for exterior rear-view mirrors to camera monitor systems;
• reduce the speed threshold for deactivation of emergency controls from 5 km/h to 3 km/h;
• clarify the requirements concerning the height of steps in vehicles which comply with Annex 8;
• limit the mandatory application of the requirements for dedicated areas for prams and pushchairs to Class I vehicles;
• require activation of the alarm and fire suppression systems as soon as the heater is in function regardless of whether the engine is operating;
• extend requirements for exposed seats adjacent to step wells to apply to other exposed seats where there is a risk of the occupant being thrown forward; and
• correct the text of the Regulation.

1. extend requirements for exterior rear-view mirrors to camera monitor systems;
2. reduce the speed threshold for deactivation of emergency controls from 5 km/h to 3 km/h;
3. clarify the requirements concerning the height of steps in vehicles which comply with Annex 8;
4. limit the mandatory application of the requirements for dedicated areas for prams and pushchairs to Class I vehicles;
5. require activation of the alarm and fire suppression systems as soon as the heater is in function regardless of whether the engine is operating;
6. extend requirements for exposed seats adjacent to step wells to apply to other exposed seats where there is a risk of the occupant being thrown forward; and
7. correct the text of the Regulation.

Proposal to mandate fire suppression systems on Class I and II buses.

Proposal to remove the provisions for welded constructions of compressed natural gas (CNG) cylinders or metal liners, including high-strength steel CNG cylinders and consolidating the earlier proposal (from document WP.29/2015/90 that was adopted but set aside at the November 2015 WP.29 session pending the proposal on cylinder construction) to regulate the discharge direction of pressure relief devices on CNG containers.

This proposal clarifies that the provisions concern any cable used in the entire vehicle, not only to those in the interior compartment, engine compartment and separate heater compartment. The proposal also clarifies that the regulation applies not only to electric cables, but also to cable sleeves or cable conduits 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.

Proposal to modify UN R125 in line with the amendment to UN R46 (indirect vision) that introduces the use of camera-monitor systems (CMS) in place of rear-view mirrors. This proposal also ends the temporary exemption permitting CMS device obstruction of driver field of view from 1 September 2021.

Proposal to allow for small variations in the presentation of motorcycle telltales and control symbols.

Correction of the French text only of the 01 series of amendments to UN R73.

Pending requests and future items for changes to UN R55.

Chronology summarizing the discussions held on agricultural coupling requirements under UN R55 since 2011.

Proposal to allow for a vertical load up to 80 kg for drawbar coupling designs with a jaw that pivots about the horizontal transverse axis because such configurations are commonly used in fire trucks and other special use vehicles in Germany, Austria and Switzerland.

Proposal as developed by the UN R55 informal group during its 12th session. This proposal concerns a procedure to identify allowable combinations of performance values Dc and V for drawbar coupling equipment. This proposal would amend the Revision 2 proposal for UN R55.

Revised proposal developed by the UN R55 informal group to introduce provisions for mechanical couplings used in modular vehicle combinations (e.g., rigid truck + dolly + semi-trailer) presently not addressed within the regulation.

Proposal from the informal group on UN Regulation No. 55 to introduce provisions for coupling applications in multi-vehicle combinations ( e.g. rigid truck + dolly + semi-trailer) presently not addressed by the regulation.

Further refinements from the informal group on UN Regulation No. 55 to introduce provisions for modular vehicle combinations (e.g., rigid truck + semi-trailer + dolly). This proposal concerns a procedure to identify allowable combinations of performance values Dc and V for drawbar coupling equipment.

Quick review of the informal group’s anticipated schedule for completing its work on updating the regulation on mechanical couplings.

One of the outcomes of the work on updating UN R55 was the recognition that agricultural couplings present a set of challenges distinct from other vehicles. Therefore, Germany proposes the establishment of an informal working group to develop a new regulations (UN R55-A) to respond to the specific needs of agricultural vehicle couplings.

Request for task force views with regard to the work on automatic emergency call devices (AECD):

1. Does R10.04 (and any later version) fully cover the EMC aspects for AECD components to be fitted to vehicles and for vehicles with these systems installed/integrated?
2. If not, what amendments can be proposed to Regulation 10?
3. Are specific EMC provisions necessary within the Regulation on AECS?

Proposed text for determining worst case conditions for physical testing of couplings.

Informal group schedule for finalizing amendments to update UN R55.

Revised version of document GRRF-80-41 pursuant to the 12th UN R55 informal group session. GRRF-80-41 was the revised formal proposal to GRRF to update UN R55 with respect to:
a) Requirements on remote indication,
b) Availability of information on coupling fixing points for A50X couplings,
c) On lateral strength of drawbars, and
d) a new class definition for fully automatic drawbar couplings.

During its first session, the EMC Task Force considered proposal regarding the application of UN R10 to trolley buses (under UN R107), to UN R46 (indirect vision and camera monitor systems), and to the work on automatic emergency call systems (AECS), as well as a proposal to amend UN R10 itself. OICA provides the views of its EMC experts in this document.

Proposal discussing the need for addition of an objective test procedure for post-crash testing and improvement in currently described subjective HF audio
assessment procedure.

Proposal for AECS compliance validation based on ITU-T P.1140.

One of the outcomes of the work on updating UN R55 was the recognition that agricultural couplings present a set of challenges distinct from other vehicles. This revised proposal takes into account comments received during the February 2016 GRRF session for the establishment of an informal working group to develop a new regulation (UN R55-A) to respond to the specific needs of agricultural vehicle couplings.

Revised proposal to ensure that coupling balls do not block rear lighting and/or registration plates. In line with the EU General Safety Rule, Annex IV specification for application of UN R55, couplings that might block lighting or plates must be removable, repositionable, and unlockable in order to make it easier for users to remove them or reposition them when not in use (e.g., towing a trailer.) Coupling balls that are so designed as to be unable to block lighting or plates may still incorporate locks and/or require tools to remove or reposition.

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.

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.

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.

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.

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.

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.

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).

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).

Proposal to include the liquefied natural gas (LNG) fuel connector provisions as specified in ISO 12617:2015.

Review of work towards adapting and/or approving certain UN Regulations for use within the International Whole Vehicle Type Approval regulation.

WP.29 adoption of the new IWVTA regulation (UN Regulation No. 0) is anticipated for March 2017 with an entry-into-force the following October. This initial regulation (00 series of amendments) will include UN Regulations as they stand prior to September 2, 2017. However, a number of these regulations contain transitional provisions such that new versions will enter into force during the 12 months following this cut-off date. Therefore, this document proposes a list of such regulations that would be included in the 01 series of amendments to UN R0 to be submitted for adoption by WP.29 in November 2017. In concept, UN R0 would be updated with these “upgraded” versions of the UN Regulations.

Proposal to require the installation of a message routing function (per ISO 11992) on trailers that are:

• equipped with more than one brake electronic control unit,
• equipped with an electric control, and
• towing a trailer.

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.

Proposal to harmonize the Russian text with the English-language version of the regulation.

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.

Proposed corrections to the original proposal to align UN R105 with ADR 2017.

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).

Proposal to clarify paragraph 7.7.5.1. with regard to ceiling-mounted displays or monitors and simplify the testing procedure:

• The gauge shall be used only for the identification of the monitors to be tested.
• 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.
• The test must be conducted in both directions.
• The proposed wording for the last condition to fulfil is more technology neutral, the case of automatic redeployment is also considered and banned.

Proposal 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 use on [traffic] roads may be partly or fully exempted from this Regulation, subject to the decision of the Type Approval Authority.”

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.”

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.

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.

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.

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.

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.

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.

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).
