| Summary | UN R90 unintentionally omits the bedding procedure for the brake drum high load test for M2, M3, N2 and N3 vehicles. CLEPA proposes using the same bedding procedure as already adopted for the thermal fatigue test for such vehicles and for the high load tests for trailers. | ||||||||

22. The expert from CLEPA presented GRRF-72-15, superseding ECE/TRANS/WP.29/GRRF/2012/3, on the “Bedding in” test procedure for brake drums. GRRF adopted the proposal as reproduced in Annex VI and requested the secretariat to submit it to WP.29 and AC.1, as a Corrigendum to ECE/TRANS/WP.29/2012/4, for consideration at their March 2012 sessions. 23. The expert from FEMFM introduced GRRF-72-05 superseding ECE/TRANS/WP.29/GRRF/2012/3 clarifying the meaning of “identical” brake linings. Following the discussion, he presented, jointly with the expert from Spain, a revised proposal (GRRF-72-05-Rev.1). GRRF supported the approach but noted some concerns and agreed to resume consideration of this subject at its next session. This will be on the basis of an official document to be prepared by FEMFM jointly with Spain, the Russian Federation and OICA. |
