2. UN Global Technical Regulation No. 7 (Head restraints)

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.

GRSP-64-39/Rev.1 | GTR 7: Proposal for Amendment 1 (Phase 2 development) 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.
GRSP/2018/27 | GTR 7: Proposal for Amendment 1 Latest developments from the GTR 7 informal group to implement the Phase 2 development of the GTR. Phase 2 addresses a new measurement procedure for the effective height of the head restraint and introduction of the Biofidelic Rear Impact Device (BioRID).

5. In the same time, the expert from Japan introduced the eighth status report of the Informal Working Group (IWG) on Head Restraints. The expert from OICA suggested that both UN GTR No. 7 and UN Regulation No. 17 be kept aligned. However, he added that if, at this time, it was difficult to maintain alignment, he urged GRSP to at least amend UN Regulation No. 17 to include the outcome of the IWG work. The expert from CLEPA introduced GRSP-64-44, expressing concerns on repeatability and reproducibility of BioRID test results and suggesting permissible variations to the injury criteria. GRSP noted that a proposal for amendments to Mutual Resolution No. 1 (M.R.1), which incorporated drawings and specifications of the BioRID dummy would possibly be presented at the May 2019 session of GRSP.

GRSP-64-40 | GTR 7: Draft 8th progress report of the informal group on Phase 2
GRSP-64-44 | GTR 7: Dynamic criteria for the BioRID dummy Report on CLEPA assessments of the proposed GTR 7 Phase 2 BioRID criteria.

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.

GRSP-64-25 | UN R17: Proposal for a 10 series of amendments Proposal to clarify the application of GTR 7 Phase 2 static alternative provisions and to modify the allowed range of tolerances under the backset retention and energy dissipations test.
GRSP-64-39/Rev.1 | GTR 7: Proposal for Amendment 1 (Phase 2 development) 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.

3. UN Global Technical Regulation No. 9 (Pedestrian safety)
3. (a) Proposal for Amendment 2 (Phase 2)

7. The expert from Germany, on behalf of the Chair of the pedestrian safety IWG, informed GRSP that a proposal for the new Addendum 3 to M.R.1, incorporating drawings and specifications of the Flex Pedestrian Legform Impactor (FlexPLI), would be introduced at the May 2019 session of GRSP on the basis of a template that was being developed by the Phase 2 IWG on UN GTR No. 7 (see para. 5 above).

3. (b) UN Global Technical Regulation No. 9: Proposal for Amendment 3

8. The expert from the United States of America, informed GRSP that his administration had previously planned to issue a Notice of Proposed Rule-Making (NPRM) to adopt Phase 1 of GTR No. 9. However, he added that given higher priorities, the NPRM would be published in a foreseeable future. The expert from OICA expressed his intention to continue to work on harmonizing UN GTR No. 9 with UN Regulation No. 127 which had already incorporated the proposed amendment. He suggested that at the March 2019 session of the Executive Committee of the 1998 Agreement (AC.3), the Chair of GRSP could explain the current situation and explore the possibility that the amendment to the UN GTR can be submitted for vote by AC.3. The Chair of GRSP confirmed that this subject would be mentioned during his highlights of GRSP December 2018 session and that possible solutions would be explored.

3. (c) UN Global Technical Regulation No. 9: Proposal for Amendment 4

9. The expert from the Republic of Korea, Chair of the IWG on Deployable Pedestrian Protection Systems (DPPS) introduced GRSP-64-36 to inform GRSP about the status of the IWG work. He explained that the group had last convened in Geneva on 11 December 2018. He added that the group was working to develop new and more detailed requirements to ensure that deployable systems were correctly activated as designed to protect pedestrians and other vulnerable road users. He underlined that among the major issues was the validation of the Head Impact Time (HIT) determination procedure and that the group was considering both numerical simulation and physical dummy testing. The expert from OICA stated that when numerical simulation was conducted, the manufacturer should provide supporting evidence showing the appropriateness of the simulation tool and suitable biofidelity and kinematics of the chosen numerical models. Therefore, he recommended that the walking posture of the model should be in M.R.1. and be updated regularly. The expert from the Republic of Korea concluded that IWG also was considering the development of a corresponding proposal to amend UN Regulation No. 127. GRSP agreed to resume consideration on this agenda item at its May 2019 session.

4. UN Global Technical Regulation No. 13 (Hydrogen and Fuel Cell Vehicles)

10. The expert from the United States of America, on behalf of the co-sponsors (Japan, Republic of Korea, European Union) and the members of the IWG on UN Global Technical Regulation (UN GTR) No. 13 – Phase 2, informed GRSP about the group’s progress. He reported that the last IWG meeting had been held in Brussels from 9 to 11 October 2018, and had been attended by more than sixty representatives from various contracting parties, motor vehicle and container industries, standard organizations and academia. He added that experts had continued discussing major technical items for Phase 2, requirements for heavy vehicles and buses, material compatibility, tank stress rupture, fire test parameters and clarification of existing UN GTR test procedures. The next IWG meeting was scheduled for March 2019. He added that the five Task Forces (TF) had provided their state of progress and issues:

  1. TF No.1 – Heavy duty vehicles and buses, had an extended discussion as the fuel system is significantly different than those in light duty vehicles. The requirements needed to be well thought out due to differences in architecture, usage and application. TF had begun monthly web meetings to identify relevant topics and to hold discussions;
  2. TF No. 2 – Fuelling receptacle requirements, had planned to submit a draft proposal for fuelling receptacle requirements at the next working group meeting;
  3. TF No. 3 – Recommendations for test procedures, was progressing well and should complete its work by the summer of 2019;
  4. TF No. 4 – Fire test, was also progressing well and was scheduled to complete its work in 2019;
  5. TF No. 5 – Recommendations from ISO TC197, had recommended a technical information proposal for the rationale section.

5. Harmonization of side impact dummies

11. The Chair of GRSP reminded GRSP about the decision of the National Highway Transport Safety Administration (NHTSA) to no longer be IWG Chair due to lack of resources. He recalled the statement of the expert from Germany at the December 2017 session of GRSP (ECE/TRANS/WP.29/GRSP/62, para. 10) that the addenda of M.R.1 which incorporates anthropomorphic test device (crash test dummies) specifications, particularly of side impact dummies (e.g. World Side Impact Dummy fiftieth percentile), be completed as soon as possible. Therefore, he encouraged Germany finding a solution for the chairmanship of the group.

6. UN Global Technical Regulation No. 20 (Electric vehicle safety)

12. The expert of the United States of America, on behalf of the co-sponsors (European Union, China and Japan) and the members of the IWG GTR No. 20, Phase 2, reported on the work progress of the group. He said that the IWG had met in Sweden from 11 to 13 September 2018. He expressed that the IWG continued the discussions on major technical issues, such as thermal propagation, water immersion, toxicity and gas management, and 3D vibration. He noted that “The White Paper” on the topic of thermal propagation was discussed extensively and updated. He added that the IWG also discussed issues regarding water immersion and vibration of the battery system and raised fundamental concerns on: (a) lack of field data and justification for the water immersion requirement and (b) vibration requirement is mainly for reliability/durability instead of for safety purpose. He finally announced that IWG aimed to complete its work by 2021 and that the next meeting of the IWG was planned from 22 to 24 January 2019, in Detroit, United States of America.

13. The expert from OICA underlined the complexity of the work involved to cover all areas not strictly related to electric vehicles and urged participation from the experts on frontal and lateral collisions, with expertise from the different fields of UN Regulations annexed to the 1958 Agreement. The Chair of GRSP clarified that the aim of IWG was not to regulate crash tests of electric vehicles instead the aim is to develop pass/fail criteria after the crash tests. However, he clarified that in parallel to the framework of IWG activities, a subgroup had been established to align UN Regulation No. 100 with UN GTR No. 20. He suggested inviting experts on UN Regulations Nos. 94 and 95 to participate in the activities of that subgroup. The expert from Japan announced that he was closely working with the experts from OICA and EC to present an informal proposal for a new series of amendments to align UN Regulation No. 100 with Phase 1 of UN GTR No. 20 by the May 2019 session of GRSP.

7. UN Regulation No. 14 (Safety-belt anchorages)

14. The expert from France introduced GRSP-64-12 which corrected a typo error in the communication annex of UN Regulation No. 14. GRSP adopted GRSP-64-12 (reproduced in Annex II of the session report) and requested the secretariat to submit it as Corrigendum 1 to Supplement 6 to the 07 series of amendments to UN Regulation No. 14, for consideration and vote at the June 2019 sessions of WP.29 and AC.1.

GRSP-64-12 | UN R14: Proposal for Corrigendum 1 to Supplement 6 to the 07 series of amendments Proposal to update a reference regarding ISOFIX exemptions permitted under paragraph 5.3.8.8. (related to vehicles with one seat position per row). The reference should read 5.3.8.8. and 5.3.8.9.
8. UN Regulation No. 16 (Safety-belts)

15. The expert from the Netherlands introduced ECE/TRANS/WP.29/GRSP/2018/25 to correct the type approval communication to extend the requirements for the safety-belt reminder installation not only to the driver’s seat. Since, the proposed amendment would entail broader technical aspects, GRSP agreed to incorporate it in a further proposal of amendments to UN Regulation No. 16. Finally, GRSP agreed to resume discussion on this subject at its May 2019 session.

GRSP/2018/25 | UN R16: Proposal for a corrigendum 1 to the 07 series of amendments Proposal to update the Communication Form since from the 07 series of amendments rear safety belt reminders have been added.
9. UN Regulation No. 17 (Strength of seats)

16. The experts from Japan and EC introduced GRSP-64-37 on the proposal of amendments (ECE/TRANS/WP.29/GRSP/2018/34) to UN Regulation No. 17 (Strength of seats) that would align it with Phase 2 of UN GTR No. 7 (see para. 5 above). The expert from CLEPA introduced GRSP-64-25, to clarify static alternative provisions of UN GTR No. 7, Phase 2 and modifications to the allowed range of tolerances to backset retention and to the energy dissipation test. GRSP agreed to hand over GRSP-64-25 to the IWG for its possible integration in the proposal of amendments to UN Regulation No. 17 and to the draft amendment to UN GTR No. 7. GRSP agreed to resume discussion on this subject at its May 2019 session on the basis of the progress of the IWG work.

GRSP-64-25 | UN R17: Proposal for a 10 series of amendments Proposal to clarify the application of GTR 7 Phase 2 static alternative provisions and to modify the allowed range of tolerances under the backset retention and energy dissipations test.
GRSP-64-37 | UN R17: Presentation on the revision to align UN R17 with GTR 7 (document GRSP/2018/34)
GRSP/2018/34 | UN R17: Proposal for the 10 series of amendments Proposal transposing the provisions of the draft GTR 7-Amendment 1 (aka Phase 2) into UN R17. Phase 2 addresses a new measurement procedure for the effective height of the head restraint and introduction of the Biofidelic Rear Impact Device (BioRID).

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.

GRSP-64-21 | UN R17: Proposal for amendments Revised proposal (superseding GRSP-63-24) to clarify the possibility to install side-facing seats in buses of category M<sub>2</sub> and M<sub>3</sub> of classes A and I.
10. UN Regulation No. 22 (Protective helmets)

18. The expert from Italy, Chair of the IWG on Protective Helmets (IWG-PH), informed GRSP about the work progress of the group which had last convened on 10 December 2018 in Geneva. He explained that IWG had examined a first draft proposal that received support to explore specific items (e.g. electronic equipment, rotational testing and so on). The expert from Germany suggested a two-phase work plan on the draft amendments to the UN Regulation:

  1. Phase 1 introduces the most needed modifications and changes and
  2. Phase 2 introduces test technology that requires research and longer discussion.
The expert from the Netherlands expressed concerns on the tight deadline of the IWG mandate (December 2019). The expert from CI stated that the first priority of his organization was to improve safety and supported the proposal from the expert of Germany. Finally, GRSP agreed with the plan proposed by the IWG:
  1. provide an updated version of the proposal to its experts and receive comments by end of January 2019,
  2. organize a webex meeting during the first week of February 2019,
  3. submit an official proposal by 15 February 2019,
  4. receive new comments by April 2019 and
  5. possibly submit an informal document amending the official proposal by the GRSP May 2019 session.

11. UN Regulation No. 29 (Cabs of commercial vehicles)

19. GRSP resumed discussion of GRSP-62-11 on proposed tolerances for the position of the loading device during the test. GRSP noted that the proposal had already been agreed in principle during the sixty-second GRSP session (ECE/TRANS/WP.29/GRSP/62, para. 20). The expert from OICA requested further consultation on the proposal and GRSP requested the secretariat to distribute GRSP-62-11 with an official symbol at its May 2019 session.

GRSP-62-11 | UN R29: Proposal for Supplement 4 to the 03 series of amendments Proposal to introduce a tolerance for the position of the loading device during the test. The loading device is required to be parallel to the x-y plane of the chassis. This proposal would add a z dimension to the x-y plane and set a tolerance such that the loading device may not deviate by more than 5° along the z-axis.
12. UN Regulation No. 44 (Child Restraint Systems)

20. The expert from IC introduced GRSP-64-32 which explained that for the forthcoming entry into force of “Phase 3” of UN Regulation No. 129 (belted Enhanced Child Restraint Systems (ECRS)), all groups and categories except Group III on forward-facing non-integral CRS would be covered. Accordingly, he explained that belted CRS could be still approved according to UN Regulation No. 44 for an undefined period. He therefore proposed to phase out this category of CRS (ECE/TRANS/WP.29/GRSP/2018/26). The proposal received comments on the transitional provisions and GRSP considered GRSP-64-35-Rev.1. Finally, GRSP adopted ECE/TRANS/WP.29/GRSP/2018/26, as amended by Annex IV to the session report, and requested the secretariat to submit it as Supplement 16 to the 04 series of amendments to UN Regulation No.44, for consideration and vote at the June 2019 sessions of WP.29 and AC.1.

GRSP-64-32 | UN R44: Phase out of belted integral CRS approvals
GRSP-64-35/Rev.1 | UN R44: Proposal for Supplement 16 to the 04 series of amendments Proposal to cease new CRS approvals under UN Regulation No. 44 as of [1 September 2020], including amended transitional provisions.
GRSP/2018/26 | UN R44: Proposal for Supplement 16 to the 04 series of amendments Proposal to prohibit the granting of new approvals under UN R44 from [1 September 2020] and to amend the transitional provisions accordingly.

21. The expert from CI introduced GRSP-64-33 on the Child Restraint System Evaluation Programme (PESRI), conducted in Latin American countries and sponsored by FIA, Global NCAP and CI research and tests. He highlighted that from this programme had emerged several regulatory irregularities, poor market surveillance and easily-granted approvals. The experts from other contracting parties stated that in their countries, market surveillance was an issue for child restraint systems and protective helmets.

GRSP-64-33 | Child Restraint System Evaluation Programme (PESRI)
13. UN Regulation No. 80 (Strength of seats and their anchorages (buses))

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.

GRSP-64-19 | UN R80: Proposal for amendments to document GRSP/2018/10 Proposal to add injury criteria in relation to the neck bending moment along the lateral axis (not to exceed 57 Nm when stretched), clarify the distance between the seats to align with IN R107, and annulation of the proposal to delete paragraph 2.1.2 because the scope of UN R80 provides for testing of seats for vehicles of M<sub>2</sub> and M<sub>3</sub> categories of II, III and B classes where approval is allowed via testing without a vehicle and mounted rigidly on a test platform.
GRSP-64-19/Add.1 | Study of the passengers’ level of protection in a frontal collision for buses equipped with the seats with lap belts and lap-shoulder belts
GRSP-64-22 | UN R80: Proposal for the 04 series of amendments Proposal to delete Appendix 5 as a basis for type approval and thereby end static testing as a compliance option.
GRSP-64-23 | UN R80: Proposal for the 05 series of amendments 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.
14. UN Regulation No. 94 (Frontal collision)

23. No new information was provided under this agenda item.

15. UN Regulation No. 95 (Lateral collision)

24. No new information was provided under this agenda item.

16. UN Regulation No. 100 (Electric power trained vehicles)

25. GRSP noted GRSP-64-24, tabled by the expert from the Netherlands to extend the functional safety in UN Regulation No. 100 to other categories of vehicles. Referring to the work in progress of aligning UN Regulation No. 100 to UN GTR No. 20, the expert from OICA suggested to include this proposal in the programme of work of the IWG on UN GTR No. 20. Finally, GRSP agreed to resume discussion on this agenda item and requested the secretariat to distribute GRSP-64-24 with an official symbol at its May 2019 session.

GRSP-64-24 | UN R100: Proposal for the 02 series of amendments Proposal to explicitly state that functional safety requirements apply to categories of vehicles beyond M<sub>1</sub>.
17. UN Regulation No. 111 (Uniform provisions concerning the approval of tank vehicles of categories N and O with regard to rollover stability)

26. No new proposal was provided under this agenda item (see para. 46 below).

18. UN Regulation No. 127 (Pedestrian safety)

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.

GRSP-64-20 | UN R127: Proposal for collective amendments to 00, 01 and 02 series of amendments 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.
19. UN Regulation No. 129 (Enhanced Child Restraint Systems)

29. The expert from Spain introduced GRSP-64-06, GRSP-64-02-Rev.1, GRSP-64-03-Rev.1, GRSP-64-04-Rev.1 and GRSP-64-05-Rev.1 which aimed at providing better provisions for the dummy’s head displacement when surpassing the reference plane DE during frontal and rear impact tests of forward facing Enhanced Child Restraint Systems (ECRS). She explained that these documents were revised proposals and have already been introduced at the May 2018 session of GRSP (ECE/TRANS/WP.29/GRSP/63, para. 33) to provide better rationales for the sled test. GRSP adopted GRSP-64-02-Rev.1, GRSP-64-03-Rev.1, GRSP-64-04-Rev.1 and GRSP-64-05-Rev.1 as reproduced in Annex V to the session report. The secretariat was requested to submit GRSP-64-02-Rev.1 as draft Supplement 9 to the original version of UN Regulation No. 129, GRSP-64-03-Rev.1 as draft Supplement 6 to the 01 series of amendments, GRSP-64-04-Rev.1 as draft Supplement 5 to the 02 series of amendments and GRSP-64-05-Rev.1 as draft Supplement 2 to the 03 series of amendments to UN Regulation No. 129 for consideration and vote at the June 2019 sessions of WP.29 and AC.1.

GRSP-64-02/Rev.1 | UN R129: Proposal for Supplement 9 to the 00 series of amendments Proposal to clarify that assessment of the DE plane only applies to rearward-facing Child Restraint Systems (CRS) in UN Regulation No. 44 and therefore does not apply to forward-facing child restraints that maintain structure of the child restraint behind the head of the dummy.
GRSP-64-03/Rev.1 | UN R129: Proposal for Supplement 6 to the 01 series of amendments Proposal to clarify that assessment of the DE plane only applies to rearward-facing Child Restraint Systems (CRS) in UN Regulation No. 44 and therefore does not apply to forward-facing child restraints that maintain structure of the child restraint behind the head of the dummy.
GRSP-64-04/Rev.1 | UN R129: Proposal for Supplement 5 to the 02 series of amendments Proposal to clarify that assessment of the DE plane only applies to rearward-facing Child Restraint Systems (CRS) in UN Regulation No. 44 and therefore does not apply to forward-facing child restraints that maintain structure of the child restraint behind the head of the dummy.
GRSP-64-05/Rev.1 | UN R129: Proposal for Supplement 2 to the 03 series of amendments Proposal to clarify that assessment of the DE plane only applies to rearward-facing Child Restraint Systems (CRS) in UN Regulation No. 44 and therefore does not apply to forward-facing child restraints that maintain structure of the child restraint behind the head of the dummy.
GRSP-64-06 | UN R129: D-E Plane Assessment Explanatory notes related to formal documents GRSP/2018/19 to 22 Explanatory notes related to formal documents GRSP/2018/ 19 through 22 (superseded by informal documents GRSP-64-02 to GRSP-64-05) submitted by Spain for the 63rd GRSP session.

30. The expert from Spain also introduced GRSP-64-10 to present GRSP-64-07, GRSP-64-08-Rev.1 and GRSP-64-09 which aimed at updating the arrangements of the approval mark. GRSP adopted GRSP-64-07, GRSP-64-08-Rev.1, GRSP-64-09 and GRSP-64-31 as reproduced in Annex V to the session report. The secretariat was requested to submit GRSP-64-08-Rev.1 and GRSP-64-31 as part of (see para. 29) draft Supplement 5 to the 02 series of amendments, GRSP-64-07 and GRSP-64-09 as part of (see para. 29) draft Supplement 2 to the 03 series of amendments to UN Regulation No. 129 for consideration and vote at the June 2019 sessions of WP.29 and AC.1.

GRSP-64-07 | UN R129: Proposal for Supplement 2 to the 03 series of amendments Proposal to modify the approval markings:<ul><li>specify the dimensions of the approval number</li><li>update i-Size universal ISOFIX, Specific Vehicle ISOFIX, i-Size Booster seat and Specific Vehicle Booster seat numbering (omitted in WP29-2018-045)</li><li>rearrange the dimensions mark for arrangements of the approval mark where used in combination with the module mark</li><li>change the 145 cm stature of the Specific Vehicle Booster seat to 150 cm stature as this is the correct upper limit.</li></ul>
GRSP-64-08/Rev.1 | UN R129: Proposal for Supplement 5 to the 02 series of amendments Proposal to modify the approval markings for consistency between technical services and approval authorities and between the labels of products approved under the 02 and 03 series. Combinations of approval marks can be made as long as the categories are able to be combined (category-wise as given in paragraph 3.2.2 and as long as it is one approval number). By combining approval marks, space on the Enhanced Child Restraint can be saved and more space is available for clear installation and use instructions. The current layout of the module label in UN R129.02 is technically impossible because the example provides a rectangular shape, with the module and base placed next to each other and joined with a plus mark while the given symbols are on top of each other and joined with an arrow mark.
GRSP-64-09 | UN R129: Proposal for Supplement 2 to the 03 series of amendments Proposal to modify the approval markings for consistency between technical services and approval authorities and between the labels of products approved under the 02 and 03 series. Combinations of approval marks can be made as long as the categories are able to be combined (category-wise as given in paragraph 3.2.2 and as long as it is one approval number). By combining approval marks, space on the Enhanced Child Restraint can be saved and more space is available for clear installation and use instructions.
GRSP-64-10 | UN R129: Explanatory notes on the proposals to update approval mark arrangements Explanation of informal documents GRSP-64-07 to -09 regarding the rearrangement of approval markings.
GRSP-64-31 | UN R129: Proposal for Supplement 5 to the 02 series of amendments Proposal to specify the dimensions of the approval number, correct term from " Regulation No. 129-02" to "UN Regulation No. 129/02", and change the 145 cm stature of the Specific Vehicle Booster seat to the 150 cm stature as this is the upper limit.

31. The expert from CLEPA introduced ECE/TRANS/WP.29/GRSP/2018/24 to clarify the definition of “infant carrier” and ECE/TRANS/WP.29/GRSP/2018/28 to clarify that certain user information was displayed sufficiently. The expert from Spain introduced GRSP-64-28 to improve the consistency of the information. GRSP adopted ECE/TRANS/WP.29/GRSP/2018/24 and ECE/TRANS/WP.29/GRSP/2018/28 as amended by Annex V to the session report. The secretariat was requested to submit ECE/TRANS/WP.29/GRSP/2018/24 as part of (see paras. 29 and 30) draft Supplement 2 to the 03 series of amendments and ECE/TRANS/WP.29/GRSP/2018/28 as part of (see para. 29) draft Supplement 9 to the original version of UN Regulation No. 129, as part of (see paras. 29 and 30) Supplement 6 to the 01 series of amendments, as part of (see paras. 29 and 30) draft Supplement 5 to the 02 series of amendments and as part of (see paras. 29 and 30) draft Supplement 2 to the 03 series of amendments to UN Regulation No. 129 for consideration and vote at the June 2019 sessions of WP.29 and AC.1.

GRSP-64-28 | UN R129: Proposal of amendments to GRSP/2018/28 Labels under UN R129, paragraph 4.5. highlight that the ECRS should not be used by children under 15 months old. This proposal presents the same layout for rearward/forward-facing and for forward-only CRS.
GRSP/2018/24 | UN R129: Proposal for Supplement 2 to the 03 series of amendments Proposal to remove references to age limits in preference for limits based on stature in the definition of "infant carrier", to update the transitional provisions in line with the new guidelines on regulatory procedures (ECE/TRANS/WP.29/1044/Rev.2), especially concerning extensions of approvals, and to replace a reference in para. 16.11 to "vehicle approval" with "Enhanced Child Restraint Systems".
GRSP/2018/28 | UN R129: Proposal for Supplement 9 to the 00 series of amendments, Supplement 6 to the 01 series of amendments, Supplement 5 to the 02 series of amendments and Supplement 2 to the 03 series of amendments Proposal to introduce new and modified labeling and to clarify packaging information to distinguish between forward-facing-only, rear-facing-only, and convertible CRS in order to reduce the risk of users misusing these enhanced CRS.

32. The expert from CLEPA withdrew ECE/TRANS/WP.29/GRSP/2018/31 and introduced GRSP-64-42 to clarify that conformity of production (COP) testing should be conducted using the same requirements which were effective at the time of the initial approval or any later applicable extension. The expert from Italy suggested that a similar requirement could be handed over to other UN Regulations to ensure consistency of COP testing. GRSP adopted GRSP-64-42 as reproduced in Annex V to the session report. The secretariat was requested to submit GRSP-64-42 as part of (see paras. 29–31) draft Supplement 5 to the 02 series of amendments and as part of (see paras. 29–31) draft Supplement 2 to the 03 series of amendments to UN Regulation No. 129 for consideration and vote at the June 2019 sessions of WP.29 and AC.1.

GRSP-64-42 | UN R129: Proposal for Supplement 5 to the 02 series and Supplement 2 to the 03 series of amendments Proposal to clarify that Conformity of Production assessments shall be conducted under the same requirements as those of the original approval or, if applicable, the extension of the approval. This proposal supersedes the proposal to require testing of Integral ISOFIX ECRS to use the door panel geometry of the 00 series of UN R129 (document GRSP/2018/31).
GRSP/2018/31 | UN R129: Proposal for Supplement 5 to the 02 series of amendments and Supplement 2 to the 03 series of amendments The 01 series of amendments to UN R129 amended the door panel geometry to create a small opening close to the seat bight. This change protected the panel from interaction with the anchorage of the adult seat belt on the test bench (added subsequently in the 02 series). Although Integral ISOFIX Enhanced Child Restraint Systems (ECRS) do not use the belt, these CRS were also required to use this new door panel geometry. This proposal amends the 02 series of amendments to require Integral ISOFIX ECRS to use the original door panel geometry with no opening (except during extensions of approvals in which the new panel geometry was used). The proposal ensures that ISOFIX ECRS designs cannot use the opening to mitigate loads to the ECRS and dummy.

33. The expert from Spain introduced GRSP-64-30-Rev.1, to clarify the installation sequence of an infant carrier on the test bench. GRSP adopted GRSP-64-30-Rev.1 as reproduced in Annex V to the session report and requested the secretariat to submit it as part of (see paras. 29–32) draft Supplement 2 to the 03 series of amendments to UN Regulation No. 129 for consideration and vote at the June 2019 sessions of WP.29 and AC.1.

GRSP-64-30/Rev.1 | UN R129: Proposal for Supplement 2 to the 03 series of amendments Proposal to specify that, in the case of an infant carrier, the dummy shall be restrained in the Enhanced Child Restraint System before it is installed on the test bench.

34. The expert from the Netherlands introduced GRSP-64-34, amending ECE/TRANS/WP.29/GRSP/2018/33, aiming at achieving a proper legalized use of non-permanent fixed inserts in UN Regulation No. 129. GRSP adopted ECE/TRANS/WP.29/GRSP/2018/33 as amended by Annex V to the session report and requested the secretariat to submit it as part of (see paras. 29–33) draft Supplement 2 to the 03 series of amendments to UN Regulation No. 129 for consideration and vote at the June 2019 sessions of WP.29 and AC.1.

GRSP-64-34 | UN R129: Proposal for a Supplement 2 to the 03 series of amendments Proposal to specify usage requirements for unfixed CRS inserts.

35. The expert from CLEPA introduced a summary of all the documents that he had submitted (GRSP-64-29) and presented GRSP-64-16-Rev.1 on the draft 04 series of amendments to UN Regulation No. 129 (ECE/TRANS/WP.29/GRSP/2018/29 complemented by GRSP-64-15) aimed at including in the scope of the UN Regulation:

  1. non-integral Universal ECRS with no backrest (i-Size booster cushion) and
  2. non-integral Specific vehicle ECRS with no backrest (Specific vehicle booster cushion).
Moreover, the expert from CLEPA introduced a consolidated text of all the comments received (GRSP-64-43). The expert from Germany argued that the definition of i-Size was associated with an additional side-impact test to assess protection of children when the vehicle was involved in such a collision and to ensure that children under fifteen months travel in the rearward facing position. Therefore, he stated that he opposed associating the above proposed new categories of ECRS with the i-Size definition to avoid confusion among users. The expert from Japan supported the opinion of the expert from Germany. The experts from IC and EC endorsed the inclusion of such ECRS in the scope of UN Regulation No. 129 to definitively phase out UN Regulation No. 44. Finally, GRSP agreed to resume discussion on this subject at its May 2019 session. Therefore, GRSP agreed to defer the discussion on parallel amendments to other series of amendments affected by the draft 04 series of amendments (ECE/TRANS/WP.29/GRSP/2018/30, ECE/TRANS/WP.29/GRSP/2018/32 and GRSP-64-27) at its May 2019 session. Moreover, the secretariat was requested to keep GRSP-64-27 as a reference in the agenda and to distribute GRSP-64-43 with an official symbol at the next session of GRSP.

GRSP-64-15 | UN R129: Proposal for the 04 series of amendments Proposal of corrections to document GRSP/2018/29 (previously submitted by CLEPA) regarding the introduction of booster-cushion provisions into UN R129.

GRSP/2018/30 | UN R129: Proposal for Supplement 5 to the 02 series of amendments Proposal to clarify provisions for booster seats under the 02 series of amendments to avoid possible confusion with the provisions for booster cushions in the proposal for the 04 series of amendments (see document GRSP/2018/29). The proposal also adds a missing reference to Appendix 5 of UN R16 that defines envelopes for non-integral Enhanced Child Restraint Systems.
GRSP/2018/32 | UN R129: Proposal for Supplement 2 to the 03 series of amendments Proposal to clarify provisions for booster seats under the 02 series of amendments to avoid possible confusion with the provisions for booster cushions in the proposal for the 04 series of amendments (see document GRSP/2018/29). The proposal also adds a missing reference to Appendix 5 of UN R16 that defines envelopes for non-integral Enhanced Child Restraint Systems.

36. The expert from the Russian Federation introduced GRSP-64-01 to align the Russian text with the English version. The expert from France introduced a similar proposal (GRSP-64-11) to align the French text. GRSP adopted GRSP-64-01 and GRSP-64-11 as reproduced in Annex V to the session report. The secretariat was requested to submit GRSP-64-01 as draft Corrigendum 3 to the original text of UN Regulation No. 129 and GRSP-64-11 as draft Corrigendum 1 to the 03 series of amendments to UN Regulation No. 129 for consideration and vote at the June 2019 sessions of WP.29 and AC.1.

GRSP-64-01 | UN R129: Proposal for draft Corrigendum 3 (Russian text only) English wording “Upper neck tension force” corresponds to the following Russian wording “Сжимающая сила верхней части шеи”. English wording “Upper neck flexion moment” corresponds to the following Russian wording “Изгибающий момент верхней части шеи”.
GRSP-64-11 | UN R129: Proposal for Corrigendum 1 to 03 Series of amendments Proposal to align the French version with the adopted English version of the text (reference document WP.29/2018/45).

37. Finally, the Chair of GRSP recommended establishing a task force of interested experts to streamline discussions on draft amendments to the UN Regulation. GRSP agreed with the proposal of its Chair and agreed to resume discussion on the basis of the outcome of meetings of the above-mentioned task force.

20. UN Regulation No. 134 (Hydrogen and Fuel Cell Vehicles (HFCV))

38. No new information was provided under this agenda item.

21. UN Regulation No. 135 (Pole Side Impact (PSI))

39. The expert from France introduced GRSP-64-14, clarifying that rear doors on the impacted side which were not directly struck by the pole, might be subjected to heavy loads. He therefore proposed a similar amendment already adopted for UN Regulation No. 95. The expert from OICA requested a study reservation. Finally, GRSP agreed to resume discussion at its May 2019 session and requested the secretariat to distribute GRSP-64-14 with an official symbol.

GRSP-64-14 | UN R135: Proposal for Supplement 2 to the 00 and 01 series of amendments Proposal to introduce objective criteria for evaluating whether a door remains latched following the pole impact test. Under UN R135, rear doors on the impacted side of the vehicle not directly struck by the pole may nonetheless be subjected to heavy loads and therefore need to be assessed. This proposal corresponds to a similar clarification already introduced into UN R95 on side impacts.
22. UN Regulation No. 136 (Electric Vehicles of category L (EV-L))

40. No new information was provided under this agenda item.

23. UN Regulation No. 137 (Frontal impact with focus on restraint systems)

41. No new information was provided under this agenda item.

24. UN Regulation No. 145 (ISOFIX anchorage systems, ISOFIX top tether anchorages and i-Size seating positions)

42. The expert from France introduced GRSP-63-13-Rev.1, to correct a typo error in the communication annex of UN Regulation No. 145. GRSP adopted GRSP-63-13-Rev.1 as reproduced in Annex VI to the session report. The secretariat was requested to submit GRSP-64-13-Rev.1 as draft Corrigendum 1 to the original text of UN Regulation No. 145 for consideration and vote at the June 2019 sessions of WP.29 and AC.1

GRSP-64-13/Rev.1 | UN R145: Proposal for Corrigendum 1 to 00 series of amendments Proposal to update a reference regarding ISOFIX exemptions permitted under paragraph 5.3.8.8. (related to vehicles with one seat position per row). The reference should read 5.3.8.8. and 5.3.8.9.
25. Mutual Resolution No. 1

43. Discussion was concluded under agenda items 3(a) and 5 (see paras. 7 and 11).

26. Securing of children in buses and coaches

44. The expert from the Russian Federation encouraged a full discussion on how to secure children in buses. He indicated that possible solutions would be the widespread use of four- or three-points safety-belts, these last with flexible straps to move the height of the effective anchorages. However, he indicated that the use of CRS would be advisable. He encouraged the use of UN Regulation No. 129, with possible adaptations, to regulate the transport of children in buses. He suggested the possibility of establishing a group of interested expert on this subject to speed up solutions. The experts from France, Germany and Spain urged a solution. The Chair of GRSP stated that NHTSA had conducted research and testing on this topic and offered to share the results of the research at the May 2019 session of GRSP. The expert from the Russian Federation and Sweden also announced testing experience and statistics on this subject and their intention to also share results at the next session.

45. Finally, GRSP agreed on the relevance of this subject and encouraged its experts to develop a strategic plan on this subject.

27. Exchange of views on Vehicle Automation

46. GRSP noted GRSP-64-45 on the decision of WP.29 to convert the Working Party on Brakes and Running Gear (GRRF) into the Working Party on Automated/Autonomous and Connected Vehicles (GRVA) and to reallocate certain tasks of GRRF to other GRs (ECE/TRANS/WP.29/1139, para. 33). GRSP also noted the recommendation of WP.29 that GRSP should insert UN Regulation No. 111 into its programme of work. The Chair of GRSP suggested that the group start exploring which areas under the responsibility of GRSP should be revised by developing vehicle automation. Thus, he indicatively mentioned topics such as safety-belts, frontal impact and seat strength and volunteered to provide a more complete list at the May 2019 session of GRSP.

GRSP-64-45 | Highlights of the first GRVA session
28. The strategy of the Inland Transport Committee

47. No new information was provided under this agenda item.

29. Election of Officers

48. In compliance with Rule 37 of the Rules of Procedure (ECE/TRANS/WP.29/690/Rev.1), GRSP called for the election of officers. The representatives of the contracting parties, present and voting, unanimously re-elected Mr. N. Nguyen (United States of America) as Chair and Mr. J.W. Lee (Republic of Korea) as Vice-Chair for the sessions of GRSP scheduled in the year 2019.

30. Other business
30. (a) Exchange of information on national and international requirements on passive safety

49. The expert from Japan introduced GRSP-64-41 on the current research programme in his country on improving pedestrian safety. He added that notwithstanding successful national regulatory efforts, pedestrians still accounted for the largest proportion of recent fatal traffic accidents. He concluded that performance protection such as at A-pillar would be increased by airbag deployment.

GRSP-64-41 | Pedestrian safety in Japan

50. Finally, GRSP agreed to defer discussion on GRSP-64-26 to its May 2019 session due to the lack of time.

GRSP-64-26 | New Legislation for Systems to Prevent Small Children from Being Left Unattended in Vehicles Presentation on Italy's National Law No.117 of 1 October 2018 which makes the use systems to prevent children from being left unattended in vehicles mandatory from 1 July 2019 for M<sub>1</sub>, N<sub>1</sub>, N<sub>2</sub>, and N<sub>3</sub> vehicles.
30. (b) Definitions and acronyms in Regulations under GRSP responsibilities

51. No new information was provided under this agenda item.

30. (c) Development of the International Whole Vehicle Type Approval (IWVTA) system and involvement of the Working Parties

52. The expert from Japan, on behalf of the new IWVTA Ambassador of GRSP, informed GRSP about the progress of the IWVTA IWG. He added that IWG had started its work on Phase 2 in May and had conveyed some proposals to the November 2018 session of WP.29. He clarified that WP.29 had agreed on the proposed “road map for IWVTA Phase 2”, inviting all GRs to review “candidates of UN regulations to be added to Annex 4 of UN Regulation No. 0”. He clarified that GRSP was asked to decide on the priority of six candidate UN Regulations, Nos. 44, 129, 134, 135, 137, and 145. He reported that the new IWVTA Ambassador had already prepared a plan including priority of the candidate items to be discussed with interested parties of GRSP prior to the May 2019 session of GRSP. He finally encouraged GRSP experts to contact him to participate in the above-mentioned preparatory work.

30. (d) Highlights of the June and November 2018 sessions of WP.29

53. The Secretary reported on the highlights of the 175th and 176th sessions of WP.29 (ECE/TRANS/WP.29/1139 and ECE/TRANS/WP.29/1142).

30. (e) Three-dimensional H-point machine

54. The Chair of GRSP informed the group, on behalf of the Chair of the three-dimensional H-point machine IWG, by reiterating his statement (ECE/TRANS/WP.29/GRSP/63, para. 50), that since the IWG had not progressed as expected, the activity of this IWG could be eventually be handed over to a new group on the development of the M.R.1 (see para. 11).

30. (f) Intelligent transport systems

55. GRSP noted that the status of the implementation of the road map on intelligent transport systems would be discussed at the February 2019 session of the Inland Transport Committee.
