GRSG | Session 116 | 8-12 Apr 2019

Agenda item 2. (a) UN Regulation No. 107 (M2 and M3 vehicles)

Proposal to refine the provisions on the number and position of emergency exits of vehicles of Classes A and B. The transition from 05-series to 06-series of amendments is based on the final proposal of the Informal Group for Service Doors, Windows, and Emergency Exits (SDWEE) adopted by GRSG as document GRSG/2012/15. One of the consequences of the new wording is that, if one escape hatch is fitted, it must be positioned in the middle third of the passenger compartment. For Class A and B vehicles with sometimes short passenger compartments (< 3 m), this can be problematic because the middle third position can overlap with the position of the service door, close to which lateral roof reinforcements are necessary to provide structural stability and meet provisions of UN R66. Given that the exact position on shorter vehicles is of lower relevance than for long compartments, this proposal would provide latitude on the exact placement for Class A and B vehicles.

GRSG | Session 103 | 2-5 Oct 2012

5. Referring to the discussion on ECE/TRANS/WP.29/GRSG/2012/2 at the previous session of GRSG, the expert from EC introduced ECE/TRANS/WP.29/GRSG/2012/23 proposing updated provisions for vehicles of Class I to provide a specific area for prams or pushchairs. The expert from IRU introduced GRSG-103-08 raising a number of concerns. The experts from Poland, the United Kingdom, CLCCR and OICA supported the concerns raised. GRSG noted a number of comments. Following the discussion, the expert from Germany volunteered to prepare, jointly with the experts from EC, France, Sweden and Switzerland, a revised proposal for consideration at the next GRSG session in April 2013 taking into account the comments received. GRSG agreed to keep ECE/TRANS/WP.29/GRSG/2012/2 and ECE/TRANS/WP.29/GRSG/2012/23 on the agenda as reference documents.

6. The expert from the Netherlands withdrew GRSG-103-05. The expert from IRU recalled the purpose of ECE/TRANS/WP.29/GRSG/2012/12 proposing to install in urban buses of Class I driver seats without suspension systems. GRSG noted no support for the proposal and agreed to remove it from the agenda.

7. The expert from CLCCR introduced GRSG-103-16 superseding ECE/TRANS/WP.29/GRSG/2012/14 on the lateral stability of rear facing wheelchairs. GRSG noted a number of concerns. As the document did not receive any support, GRSG agreed to remove it from the agenda.

8. The expert from the Russian Federation presented GRSG-103-09 amending the provisions of the installation height of interior emergency controls in Class B vehicles. GRSG agreed to resume consideration of the proposal at its next session in April 2013 on the basis of an official document.

9. The expert from Sweden introduced GRSG-103-12 justifying the installation of automatic fire suppression systems in the engine compartment of buses and coaches. GRSG followed with interest a presentation by the expert from Sweden (GRSG-103-22) on a method for testing the performance of fire suppression systems. Following the discussion, GRSG noted general support on this subject. The expert from Sweden volunteered to prepare a concrete proposal for consideration at the next session of GRSG.

GRSG | Session 116 | 8-12 Apr 2019

8. The expert from OICA presented GRSG-116-25 on specific concerns for the position of escape hatches on M2 buses of Class B in the transition from the 05 and 06 series of amendments to UN Regulation No. 107. She added that the location of such hatches was not relevant, particularly for short vehicles with a passenger compartment length of approximately 2.5 m. Thus, she proposed to amend the provisions of Annex 3 on the number and position of emergency exits of vehicles of Classes A and B (GRSG-116-24). GRSG noted general support for the proposal and some requests for clarification. The expert from OICA invited all interested experts to provide her with their comments. Thus, she volunteered to submit a revised proposal for consideration at the next session as an official document.

GRSG | Session 117 | 8-11 Oct 2019

8. The expert from OICA presented ECE/TRANS/WP.29/GRSG/2019/30 on the position of escape hatches on M2 buses of Classes A and B in the transition from the 05 and 06 series of amendments to UN Regulation No. 107. Following clarification on the positioning of escape hatches in the vehicles concerned and adjustment of language used (GRSG-117-54), GRSG adopted ECE/TRANS/WP.29/GRSG/2019/30 as amended and reproduced in Annex II to this report. The secretariat was requested to submit it to WP.29 and AC.1 as draft Supplement 7 to the 06 series of amendments, Supplement 2 to the 07 series of amendments and Supplement 2 to the 08 series of amendments to UN Regulation No. 107 for consideration at their March 2020 sessions.

GRSG | Session 104 | 15-19 Apr 2013

17. Referring to informal document GRSG-103-29 superseding ECE/TRANS/WP.29/GRSG/2012/15, the Chair recalled the outcome of discussion at the previous session of GRSG on the new requirements for service doors, windows and emergency exits. The Chair of the informal group on the informal group on Service Doors, Windows and Emergency Exits in buses and coaches (SDWEE) introduced GRSG-104-22 containing a revised text for the amendments to UN Regulation No. 107. The experts from Germany, the Russian Federation and OICA introduced GRSG-104-05, GRSG-104-23 and GRSG-104-17 proposing some improvements to the proposed text.

19. Finally, GRSG adopted ECE/TRANS/WP.29/GRSG/2012/15, as reproduced in Annex IV (based on GRSG-103-29-Rev.1), and requested the secretariat to submit the document to WP.29 and AC.1 for consideration at their November 2013 sessions, as draft 06 series of amendments to UN Regulation No. 107, subject to a final review at the next GRSG session in October 2013.
