Proposal to introduce provisions for non-original replacement silencing systems (NORESS, independent aftermarket muffler systems) with multiple, manually or electronically adjustable, rider-selectable operating modes or variable geometries (NORESS with “flexibilities”). These "flexibilities enable the replacement systems to meet the requirements of Annex 3 (i.e., during testing) while producing much higher noise (sound pressure) outside the Annex 3 conditions. This amendment would require such NORESS to meet the ASEP requirements of UN R9 and UN R41. The amendment further introduces language taken from UN R51. In effect, NORESS with flexibilities performance under normal driving conditions would not be permitted to deviate from its performance under testing.

29. The expert from Germany presented an overview of issues with noise emissions of non-original replacement exhaust silencer systems (NORESS) for L-category vehicles (GRB-67-03), as well as a possible solution in the form of a Supplement 3 to the 01 series to UN Regulation No. 92 (GRB-67-02). Following a brief exchange of views, GRB generally supported the approach and agreed that the proposed modifications should become a new series of amendments. GRB experts were invited to transmit their comments, if any, directly to the expert of Germany, so that he would be able to submit an official document for consideration at the next session.

Discussion presentation especially concerning the regulation of lane-keeping systems corresponding to SAE Level 3 automation criteria (vehicle under system control with human driver as fallback).

17. The Chair of the IWG on the Agricultural Coupling Devices and Components reported on the activities of the group (GRRF-86-06) and presented GRRF-86-02, introducing ECE/TRANS/WP.29/GRRF/2018/4 with a draft Regulation on the Agricultural Coupling. GRRF received information on the texts of para. 4.5.

18. GRRF agreed that the stress weld limit should be qualified as absolute. It adopted the document and requested the secretariat make the necessary change and to submit the proposal as new draft UN Regulation on uniform provisions concerning the approval of mechanical coupling components of combinations of agricultural vehicles to WP.29 and AC.1 for consideration and vote at their June 2018 sessions.

Proposal to expand the scope of the regulation on unauthorized L-category vehicle use to include electronic devices such as keyless entry systems, similarly to what already exists in UN R116 on passenger car use.

51. The expert from Germany introduced GRSG-114-02 which inserts new provisions on electromechanical and electronic devices to prevent unauthorized use. He added that the type approval of such smart key systems could also be an option for UN Regulation No. 116. GRSG noted general support and agreed to resume consideration of this subject at its next session in October 2018 on the basis of an official document.

Proposal from Germany and the Republic of Korea to resolve measurement concerns in the test requirements for ACSF of Category B1 and C. The proposal addresses issues identified in Annex 8, improves reproducibility and robustness of the procedures, fills in gaps in the test cases, and provides additional details on measuring equipment and test execution.

48. The expert from Germany presented GRRF-86-13 tabled by the experts from Germany and from the Republic of Korea with a proposal for amendments to the ACSF testing provisions in Annex 8 of UN Regulation No. 79, based on the first experience gathered since the 02 series of amendments of UN Regulation No. 79 entered into force. GRRF welcomed the proposal and provided comments. The experts from Germany and the Republic of Korea volunteered to prepare a revised proposal aimed to avoid prescriptive requirements on the measurement instruments and providing more detailed justification e.g. on the sample rate and the filtering of the lateral acceleration data.

53. The expert from France introduced GRVA-01-38 (based on GRRF-86-13) addressing the accuracy of interpretation of data produced during system assessment. The expert from Germany welcomed the document and proposed to consider the filtering provisions together with the tolerances. Other experts welcomed the document and agreed to study it until the next session. GRVA agreed to resume consideration of this item at its January 2019 session.

35. The expert from France introduced ECE/TRANS/WP.29/GRVA/2019/9 based on GRRF-86-13 proposing clarifications of the Annex 8 testing provisions. The proposal received some comments from Japan, France, Germany and OICA. The expert from France agreed with the suggestion of GRVA to submit a revised proposal with more data for consideration at the September 2019 session. The experts from Japan, Germany and OICA were invited to share with GRVA their test data, supporting their positions.

Possible scenarios for developing regulatory provisions for snow tyres under UN tyre regulations.

41. The expert from Germany presented GRRF-86-09 with possible scenarios for developing snow tyre provisions for all tyres and vehicles categories as it is already existing for snow tyres of category C1, C2 and C3 for vehicles categories M and N. GRRF supported the scenario 2 proposed in the document and invited the expert from Germany and other interested experts to prepare snow tyre provisions according to this scenario.

Proposal to require seat belt components such as retractors to remain functional if damaged during the load-retention test according to Annex 9 of UN R17. Such components have occasionally been damaged during testing such that their functionality has been impaired. In order to ensure adequate occupant safety, this proposal would require all safety-belt components to be included in the test installation and require post-test inspection to confirm the continued functionality.

19. The expert from Germany introduced ECE/TRANS/WP.29/GRSP/2018/4, following the discussions at the December 2018 session of GRSP, which aimed to clarify that safety-belts and their components should continue to function after the load retention test. GRSP adopted the proposal as amended in Annex VI to the session report. The secretariat was requested to submit the proposal as draft 09 series of amendments to UN Regulation No. 17 for consideration and vote at the November 2018 sessions of WP.29 and AC.1.

Proposal to introduce installation specifications for securing a cab mounted on a vehicle to the test rig for tests B and C, as is currently provided for test A, under UN R29. This proposal aims to improve repeatability and reproducibility while allowing more flexibility in permitting the use of rigid composite blocks and/or (adjustable) metal brackets in securing the vehicle in the place of the wooden block presently prescribed in Figure 1.

22. GRSP resumed discussion on this subject on the basis of a revised proposal of Germany (ECE/TRANS/WP.29/GRSP/2018/5) on how to secure a cab mounted on a vehicle on the test rig that allowed the use of rigid composite blocks and/or metal brackets instead of the wooden blocks, and on the necessity to secure the vehicle with ropes or chains for test C. GRSP adopted the proposal not amended and requested the secretariat to submit ECE/TRANS/WP.29/GRSP/2018/5 as draft Supplement 4 to the 03 series of amendments to UN Regulation No. 29 for consideration and vote at the November 2018 sessions of WP.29 and AC.1. GRSP was informed about an issue raised during at the February 2018 session of Working Party on Brakes and Running Gears about road accidents involving trucks that point to the mechanical failure of the steering gear. The expert from Germany clarified that UN Regulation No. 29 did not include the steering gear mechanism in its testing provisions.

Proposal to delete Appendix 5 and thereby end static testing as a compliance option. In addition, this proposal amends Appendix 1 by reducing the forward movement of the head of the manikin to 1.2 m in alignment with UN Regulation No. 14. Further, the proposal would limit the movement of the seat anchorages to 100 mm to ensure a minimum residual space for the passenger between the seats. Lastly, to ensure that seat fixations are reliably fastened after relocation, the proposal would require the necessary information to be marked directly on the seat and provided in the owner’s manual.

24. GRSP resumed discussion on the proposal tabled by the expert from Germany (ECE/TRANS/WP.29/GRSP/2018/10), aimed at removing the static tests and improving the dynamic test on seat anchorages. The expert from Germany continued provide evidence to GRSP through a new presentation (GRSP-63-32 and a Video Presentation No. 1) to support his proposal. He stated that the current requirements of the UN Regulation allows the approval of seat systems in busses on the basis of a static test procedure which does not provide an adequate level of protection compared with the dynamic procedure. He added that tests with one seat model showed that occupants could be exposed to a high risk of death or serious injury in an accident from the collapse of the seat fixation. Finally, he informed GRSP that comparable seat fixations failure had been observed in bus accidents, and occupants had already been killed or seriously injured. He added that the German administration is concerned that these severe accidents could happen again in the future. The expert from the Russian Federation proposed to postpone the decision to the December 2018 session of GRSP. He justified his recommendation on the lack of research on the issue. He added that the Russian Federation considered it premature to exclude static tests from UN Regulation No. 80 and proposed to revise this type of test. He also suggested amending the dynamic test methodology according to ECE/TRANS/WP.29/GRSP/2018/10 and to the outcome of research conducted in the Russian Federation. Finally, he announced his intention to present these research results, accompanied with a draft amendment to UN Regulation No. 80 at the December 2018 session of GRSP. Several experts raised a study reservation to verify further statistical data. The expert from OICA also requested more time to prepare a revised proposal and requested to keeping GRSP-63-17 as a reference in the agenda of the next session.

25. GRSP agreed to resume discussion at the December 2018 session and invited experts to reach an agreement on this subject at that session.

26. The expert from Germany informed GRSP that TF on UN Regulation No. 80 had not started work due to the absence of new proposals as an alternative to the previous proposal ECE/TRANS/WP.29/GRSP/2018/10, that had aimed at removing Appendix 5 (static test requirements and procedure) from UN Regulation No. 80. The expert from OICA introduced GRSP-65-29-Rev.1 which proposed a compromise to the complete deletion of the static test as the static test will provide the basis for a simpler testing of small projects or Class I vehicles. He proposed a two-step approach: (a) the first step was presented with GRSP-65-29 Rev.1 with more stringent requirement for the attachments and fittings of the seat and (b) the second step would be a revision of the static and dynamic test. The expert from the United Kingdom acknowledged the need of small manufacturers to retain a static test as alternative and supported the proposal as a viable compromise. The experts from Finland, Italy and Russian Federation expressed similar views. The expert from Germany acknowledged that GRSP-65-29-Rev.1 had partially solved the problem of construction and fixation, and thus should be intended as a compromise that could be improved in the future. The expert from the Netherlands suggested that in the future, only the dynamic test should be used. Finally, GRSP adopted GRSP-65-29-Rev.1, as reproduced in Annex IV of the session report. The secretariat was requested to submit GRSP-65-29-Rev.1 as new 04 series of amendments to UN Regulation No. 80, for consideration and vote at the November 2019 sessions of WP.29 and AC.1.

Consolidated draft proposal for a blind spot information systems regulation as developed under the VRU Proxi informal group, based on GRSG/2017/11.

Working draft based on the proposal in document GRSG/2017/11 with marked revisions and comments.

The target of the meeting was to define essential periodic inspection requirements to be respected when installing gaseous fuel components into a vehicle, and to clarify the material requirements for components inside the LPG tank. The work addressed UN R67 and UN R110. No further meetings are planned at this time.

23. The expert from Germany introduced GRSG-114-08 on the recent meeting of the task force on gas-fuelled vehicle regulations held in Cologne (Germany) on 6 and 7 February 2018. He added that progress had been good on UN Regulation No. 110, but the amendments to UN Regulation No. 67 were still under considerations.

Proposal developed by the Gas-fueled Vehicle Regulations Task Force to facilitate periodic inspections of gas containers through better visibility. In addition, Germany suggests adding that paragraph to allow a Contracting Party or a regional organization of Contacting Parties like the EU to refuse national or regional type-approval and to refuse first registration of a vehicle type affected by the changes introduced by the 02 series of amendments but not meeting those stipulations. Paragraph 22.13 is an addition to paragraph 22.9. giving more stress to aspects of national and regional type-approval and of first registration of vehicles.

25. The expert from Germany recalled the outcome of the task force (para. 23 above) on ECE/TRANS/WP.29/GRSG/2017/16 and presented GRSG-114-09 proposing amendments to the Regulation. GRSG noted general support and some comments. Finally, GRSG considered a revised proposal (GRSG-114-09-Rev.1) and adopted ECE/TRANS/WP.29/GRSG/2017/16 as reproduced in Annex V to the session report. The secretariat was requested to submit the proposal to WP.29 and AC.1 as draft 02 series of amendments to UN Regulation No. 67 for consideration at their November 2018 sessions.

Proposal developed by the Gas-fueled Vehicle Regulations Task Force to facilitate periodic inspections of gas containers through better visibility. In addition, Germany suggests adding a paragraph to allow a Contracting Party or a regional organization of Contacting Parties like the EU to refuse national or regional type-approval and to refuse first registration of a vehicle type affected by the changes introduced by the 03 series of amendments but not meeting those stipulations. Paragraph 24.22. is an addition to paragraph 22.18. giving more stress to the aspects of national and regional type-approval and of first registration of vehicles.

28. The expert from Germany introduced GRSG-114-10 on the outcome of the task force on ECE/TRANS/WP.29/GRSG/2017/17 which was on improving the provisions for installing and inspecting Compressed Natural Gas (CNG) cylinders or Liquefied Natural Gas (LNG) tanks and their accessories. The expert from Italy preferred a more accurate inspection of such containers without the removal of structural parts (GRSG-114-19). After discussion, GRSG agreed to add design requirements that allow easy periodical technical inspections. The expert from the Netherlands requested that container manufacturers provide more detailed recommendations for periodical technical inspections and for periodic requalification tests, and requested that these recommendations be stored and made available for all inspections.

30. Finally, GRSG considered a revised proposal (GRSG-114-10-Rev.1) and adopted ECE/TRANS/WP.29/GRSG/2017/17 as reproduced below. The secretariat was requested to submit the proposal to WP.29 and AC.1 as draft Supplement 1 to the 03 series of amendments to UN Regulation No. 110 for consideration at their November 2018 sessions.

Insert a new paragraph 18.1.6.1., to read:

a) Proposal to amend UN R48 to clarify the DRL switching-off conditions (also aligning them with the existing switching-off conditions for front position lamps reciprocally incorporated with DI) and/or light intensity reduction when DRL and DI are totally or partially reciprocally incorporated and when their distance is equal or less than 40 mm.
b) Proposal to introduce into UN R87 the possibility of a supplemental verification and certification of the “reduced luminous intensity”, fulfilling the pertinent requirements in Regulation No. 48.

28. The experts of Germany and Italy proposed a new series of amendments to Regulation No. 48 to clarify the DRL switching-off conditions and/or light intensity reduction when DRL and front direction indicators were totally or partially reciprocally incorporated and when the distance between them was equal or less than 40 mm (GRE-79-25). The expert from OICA submitted a counter-proposal (GRE-79-30). GRE invited the proponents to prepare a consolidated document for the next session.

Proposal clarify that only a 3-point-belt shall be permitted for the driver seating position in order to address differing interpretations among Technical Services regarding which requirements apply for driver position seat-belt approval.

18. The expert from Germany introduced GRSP-63-23, to clarify which requirements should be applied to approve the safety-belt of the driver’s. GRSP endorsed the proposal and agreed to finalize its discussion by combining GRSP-63-23 with GRSP-63-01-Rev.1 under agenda item 24 (see para. 42 below).

Clarification with regard to the possibility to install side-facing seats in buses of category M₂ and M₃ of classes A and I.

20. The expert from Germany also introduced GRSP-63-24 clarifying the possibility of installing side-facing seats in buses of certain classes of vehicles. The expert from the Netherlands raised a study reservation. GRSP agreed to resume discussion on this subject at the December 2018 session of GRSP on the basis of a new proposal jointly prepared by the experts from Germany and EC.

Proposal to introduce references to specifications for the construction, preparation and certification of the Flexible Pedestrian Legform Impactor (FlexPLI).

53. The expert from Germany withdrew GRSP-63-25, explaining to GRSP that he would submit a more complete document at the December 2018 session of GRSP.

The video used during the presentation can be downloaded separately.

Comments and proposed changes to the draft text with regard to the general system classification, human driver priority, and information to the driver provisions.

Working draft document based on document TFCS-12-19.

Proposal to introduce requirements for non-original replacement exhaust silencing systems with multiple, manually or electronically adjustable, rider-selectable operating modes or variable geometries (NORESS with “flexibilities”). This is a consolidated version of the amended regulation with the changes marked in bold and strikethrough text.

10. The expert from Germany presented a new series of amendments to UN Regulation No. 92 which introduce requirements for non-original replacement exhaust silencing systems (NORESS). GRB adopted the proposals and requested the secretariat to submit them to WP.29 and AC.1 for consideration and vote at their March 2019 sessions as a draft 02 series of amendments to UN Regulation No. 92.

67. In particular, the GRBP Chair mentioned that GRBP had adopted new series of amendments to UN Regulations Nos. 9 (Noise of three-wheeled vehicles) and 92 (Replacement exhaust silencing systems for motorcycles).

Proposal to clearly exempt vehicle types without a coupling system to charge the REESS in order to avoid administrative and technical burdens on vehicles outside the intended scope of the 06 series amendments.

Working draft proposal updated by Germany for the VRU-Proxi informal group for a new Regulation on uniform provisions concerning the approval of motor vehicles with regard to the Blind Spot Information System for the Detection of Bicycles

Proposal to

1. delete the requirement limiting the speed reduction during the collision-imminent warning phase
2. define a time range for the warning function to ensure adequate warning at lower speeds
3. introduce specific requirements for the achievable speed reduction for the cases of dry roads and wet roads
4. introduce speed reduction requirements at 70 km/h and 40 km/h for dry and wet roads, respectively
5. restructure provisions under “Specifications” and “Test Procedure” to enable testing at different speeds
6. prevent unintended AEBS deactivation
7. delete certain exemptions (to be addressed at national levels)

42. The expert from Germany referred to UN Regulation No. 131 and presented GRVA-01-30 (and GRVA-01-31 with a calculation tool), introducing ECE/TRANS/WP.29/GRVA/2018/4 which addressed the issues presented during the last two sessions of GRRF concerning the performance of AEBS for heavy vehicles. He explained that this revised proposal was more far reaching than the previous one, not only addressing the manual deactivation switch provisions but also other provisions that would contribute to make AEBS requirements for heavy vehicles corresponding to state of the art vehicle technologies, by changing “the structure” of the Regulation, “the vehicle target” requirements, the “overriding requirements” and the “warning strategy”. He concluded his presentation stating that these changes would help to minimize the false positive activation risks mentioned by the experts from Nordic countries as initial reaction on the German proposals at the last sessions of GRRF.

43. The experts from OICA presented (GRVA-01-21) comments on ECE/TRANS/
WP.29/GRVA/2018/4. The experts from Sweden and Japan expressed reservations on the proposal as they were not in the position at this stage to assess the implications of such far reaching changes on the performance of AEBS systems for heavy vehicles. The experts from Australia, Japan, Netherlands, Norway and Sweden agreed to work with the expert from Germany to review the proposal until the next session of GRVA. The experts agreed to work on this item via virtual meetings and physical meetings around the meetings of the IWG on AEBS.

Proposal to expand the scope of the regulation on unauthorized L-category vehicle use to include electronic devices such as keyless entry systems, similarly to what already exists in UN R116 on passenger car use.

35. The expert from Germany presented a status report of the group of interested experts from Finland, France, Germany, Japan and Russian Federation, BIPAVER and ETRTO on snow tyre provisions (GRB-68-23).

42. The expert from Germany referred to UN Regulation No. 131 and presented GRVA-01-30 (and GRVA-01-31 with a calculation tool), introducing ECE/TRANS/WP.29/GRVA/2018/4 which addressed the issues presented during the last two sessions of GRRF concerning the performance of AEBS for heavy vehicles.

He concluded his presentation stating that these changes would help to minimize the false positive activation risks mentioned by the experts from Nordic countries as initial reaction on the German proposals at the last sessions of GRRF.

43. The experts from OICA presented (GRVA-01-21) comments on ECE/TRANS/
WP.29/GRVA/2018/4. The experts from Sweden and Japan expressed reservations on the proposal as they were not in the position at this stage to assess the implications of such far reaching changes on the performance of AEBS systems for heavy vehicles. The experts from Australia, Japan, Netherlands, Norway and Sweden agreed to work with the expert from Germany to review the proposal until the next session of GRVA. The experts agreed to work on this item via virtual meetings and physical meetings around the meetings of the IWG on AEBS.

42. The expert from Germany referred to UN Regulation No. 131 and presented GRVA-01-30 (and GRVA-01-31 with a calculation tool), introducing ECE/TRANS/WP.29/GRVA/2018/4 which addressed the issues presented during the last two sessions of GRRF concerning the performance of AEBS for heavy vehicles.

The experts agreed to work on this item via virtual meetings and physical meetings around the meetings of the IWG on AEBS.

Paper by Karl Manz, Karlsruhe Institute of Technology (KIT), to identify the basic rules of a performance-based description of lighting and light-signalling regarding the needs of visual performance.

25. The expert from EC reported on the outcome of IWG on VRU-Proxi on ECE/TRANS/WP.29/GRSG/2018/24 for a new UN Regulation on BSIS. He added that IWG experts had agreed on a number of further amendments to the proposal as reflected in GRSG-115-10. The experts from Germany presented GRSG-115-33 that summarizes the amendments proposed by IWG, and GRSG-115-37 that explains the psychological approach of the driver’s turning information concept. GRSG noted GRSG-115-13 on the draft ISO standard 19206:4 referred to in the new draft UN Regulation on BSIS. The expert from OICA introduced GRSG-115-24 on the need to limit, in a first step, the scope of the new UN Regulation to vehicles of categories N2 (with a permissible technical mass higher than 8 tons) and N3 only. GRSG endorsed that position and mandated IWG on VRU-Proxi to work further on a possible extension of the scope to other categories vehicles. The expert from Israel proposed to amend paragraph 5.5.3. on the conditions to activate the warning signal (GRSG-115-36). With respect to the testing procedure of BSIS, the expert from CLEPA presented GRSG-115-30 on the ambient light conditions and GRSG-115-31 on the distance between the vehicle and the bicycle.

26. As a result of the discussion on GRSG-115-10-Rev.1, GRSG adopted ECE/TRANS/WP.29/GRSG/2018/24 as amended by Annex II to this report. The secretariat was requested to submit it to WP.29 and AC.1 as a new draft UN Regulation on BSIS for consideration at their March 2019 sessions.

Initial proposal for discussion to introduce provisions to address risk of delayed response to a signal due to sun load impact on conspicuity.

36. The expert from Germany briefly mentioned draft amendments to the LSD Regulation on the sun load impact (phantom effect) (GRE-80-27) and stated that a formal proposal would be submitted to the next session of GRE.

37. The experts of France and Germany presented the preliminary results of their questionnaire on national treatment of evocative, suggestive or figurative apparent surfaces (GRE-80-28). GRE noted that the reported results seemed to indicate the need to harmonize national regulations on the issue. GRE decided to continue this discussion at the next session, based on a more detailed document to be prepared by the experts from France and Germany.

Proposal to address new active suspension technologies that can raise the height of the vehicle in motion up to a defined speed. Since the vehicle height has an influence on the headform test area (WAD) and on the test results for legform tests, all possible vehicle heights up to a driving speed of 11.1 m/s (40 km/h) should be considered to be relevant for the impact with a pedestrian. The proposal is a clarification on this issue.To ensure that such an active suspension system is considered for type approval, there should be a detailed description in the information document. Due to the fact that extensions for an existing vehicle type concerning UN Regulation No. 127 are still possible according to 00 and 01 series of amendments, the proposal is relevant for all series of amendments of the UN R127.

27. The expert from Germany introduced GRSP-64-20, to clarify different interpretations on vehicle configuration testing in the presence of active suspensions, which arose in off-road driving (SUVs mostly) or driving in a car park (sports cars). He concluded that since the vehicle height had an influence on the headform test area and on the test results for legform tests, all possible vehicle heights up to a driving speed of 11.1 m/s (40 km/h) should be considered relevant for impact with a pedestrian. The expert of OICA agreed that the issue raised by Germany was valid and that there was a need to avoid different interpretations, but this needs to be studied carefully, also in relation to the normal procedure of “worst case definition”. He added that this would entail new requirements, therefore needing a series of amendments and transitional provisions. He also added that this issue should be considered in the ongoing WP.29 discussions on the performance of vehicles outside the test boundaries defined in the various UN Regulations. The expert from the Netherlands suggested developing simulation models to check worst case testing. The expert from OICA stressed that testing a vehicle in all potential configurations would be unrealistic and therefore welcomed the statements from the Netherlands. He referred to the work on the certification of automated vehicles whereby an additional 3-pillar approach was considered to address automation:

1. test track,
2. road test and
3. simulation and audit of development process.

28. The Chair of GRSP suggested establishing a group of interested experts to further develop the proposal. GRSP agreed with the proposal of its Chair. The expert from Germany announced a possible meeting before 15 February 2019, to submit a new official proposal. Finally, GRSP requested the secretariat to keep GRSP-64-20 as a reference in the agenda of the May 2019 session.

Revised proposal (superseding GRSP-63-24) to clarify the possibility to install side-facing seats in buses of category M₂ and M₃ of classes A and I.

17. The expert from Germany introduced GRSP-64-21, to clarify the possibility of installing side facing seats in certain bus categories (M2 and M3 of Classes A and I). GRSP adopted the proposal as reproduced in Annex III to the session report and requested the secretariat to submit it as Supplement 1 to the 09 series of amendments to UN Regulation No. 17, for consideration and vote at the June 2019 sessions of WP.29 and AC.1.

Proposal to delete Appendix 5 as a basis for type approval and thereby end static testing as a compliance option.

22. The expert from Germany introduced GRSP-64-22 and
GRSP-64-23 superseding ECE/TRANS/WP.29/GRSP/2018/10, aimed at removing Appendix 5 (static test requirements and procedure) from UN Regulation No. 80 (GRSP-64-22) and at improving the dynamic test (GRSP-64-23) in two different series of amendments. The expert from OICA suggested that both tests be maintained as alternatives and that the static test be improved as a first step. The expert from Italy supported the approach of the expert from OICA. The expert from the Russian Federation introduced GRSP-64-19 and Add.1, proposing to include the assessment of the dummy neck injury criteria into the dynamic test of the UN Regulation. The Chair of GRSP suggested creating a task force of concerned parties led by Germany to provide a revised official document that would incorporate GRSP-64-19 and other comments submitted to the secretariat by 15 February 2019. The expert from Germany agreed with the Chair’s proposal and the expert from OICA offered his contribution in drafting the revised document.

Proposal to amend Appendix 1 by reducing the forward movement of the head of the manikin to 1.2 m in alignment with UN R14. The proposal would also limit the movement of the seat anchorages to 100 mm to ensure a minimum residual space for the passenger between the seats. Lastly, to ensure that seat fixations are reliably fastened after relocation, the proposal would require the necessary information to be marked directly on the seat and provided in the owner’s manual.

The expert from Germany agreed with the Chair’s proposal and the expert from OICA offered his contribution in drafting the revised document.

Proposal to introduce a new measurement procedure for the effective height of the head restraint and introduction of the Biofidelic Rear Impact Device (BioRID). This proposal eliminates the backset measurement test procedure using the HRMD method.

4. The expert from Germany introduced GRSP-64-38, to present the proposed Amendment 2 (GRSP-64-39-Rev.1 superseding ECE/TRANS/WP.29/GRSP/2018/27) to UN GTR No. 7 (Phase 2 of the UN GTR on head restraints), jointly prepared with the experts from Japan and the Netherlands. He explained that the proposal still has several items, in several square brackets, to be solved. However, he added that the draft amendment would introduced five main changes to the UN GTR:

1. Procedure for establishing the height of the head restraint base on the head contact rather than at its absolute height;
2. Height measurement test procedure;
3. Deletion of the backset measurement test procedure using the H-point machine method;
4. Introduction of the backset measurement test procedure using the R-point method; and
5. Introduction of the dynamic performance test procedure, by using the Biomechanical Rear Impact Dummy (BioRID) and empirical criteria instead of biomechanical (due to the absence of an absolute medical definition of whiplash) to establish seat performance.

6. Finally, GRSP experts were invited to provide comments to GRSP-64-39-Rev.1 and GRSP-64-40 to the expert from Japan by the end of January 2019. Moreover, it was agreed that IWG organize a webex meeting to allow the expert from Japan to submit an official proposal of amendments, which would also incorporate GRSP-64-25 (see para. 16 of this report) by 15 February 2019.
