Proposal to clarify the verification procedures after the strength test. The proposal addresses destruction of seat mounts, injury-causing objects entering the residual space and moving within it, and emergency hatches.

Proposal to add checks under the current tests:

• damage to seat attachments
• occupant compartment hazards (e.g., risk of impact by loose objects such as fire extinguisher) and
• post-crash functionality of escape hatches (including force required to open)

101. The representative of the Russian Federation presented the informal document WP.29-179-17/Rev.1 and described the results of the state surveillance and monitoring of buses. He concluded that work would continue with finding solutions to issues that arose during the tests and asked for support on the proposals to move forward. These findings would warrant reflection related to UN Regulations Nos. 66, 80 and 107. A completed report would be available early 2020.

102. The representative of France welcomed this work, especially on UN regulation No. 66.

Proposal to specify that “handrails and handholds at doorways where the associated residual space is not designated for passengers positioned for travel, and where intrusion into the space presents no risk of contact with passengers, shall also be ignored.”

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

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

22. The expert from OICA recalled ECE/TRANS/WP.29/GRSG/2016/11 and GRSG-110-16 which propose to amend the provisions of UN Regulation No. 66 with respect to intrusion into residual space during the roll over test.

23. GRSG noted a number of comments on the draft amendments and agreed on the need to reconsider the definition of “residual space”. The GRSG Chair recommended having a final review of an updated text at the next GRSG session. He invited the experts from France, the United Kingdom and OICA to work on a joint proposal.

19. The expert from OICA withdrew ECE/TRANS/WP.29/GRSG/2016/11 and informed GRSG that the concern with UN Regulation No. 66 was resolved with an interim solution. GRSG agreed to remove this item from the agenda of its next session.
