Proposal to establish uniform provisions for gangway barriers in vehicles of Classes I and A, including a proposed 100N force limit for moving such barriers out of the way.
7. The expert from Germany introduced ECE/TRANS/WP.29/GRSG/2013/22 clarifying the technical provisions for gangway barriers in vehicles of Classes I and A. GRSG adopted the proposal, as reproduced below, and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their March 2014 sessions, as part (see para. 6 above) of draft Supplement 4 to the 04 series of
amendments to UN Regulation No. 107.
Annex 3, paragraph 220.127.116.11., amend to read:
The gangway(s) of a vehicle shall be so designed and constructed … the monitor or display device shall remain in the retracted position.
If a vehicle of Class I, II or A is fitted with a barrier, the gauging device according to Annex 4, Figure 6, may come into contact with the barrier provided that the maximum force necessary to move such barrier out of the way does not exceed 50 Newton measured at the point of contact between the gauging device according to Annex 4, Figure 6 and the barrier and applied perpendicular to the barrier.
The maximum force shall apply to both directions of movement of the gauging device.
If the vehicle is equipped with a lift adjacent to the barrier, the barrier may be temporarily blocked during the operation of the lift.”
