| Summary | The extension of UN R90 to include brake drums and discs introduced the concept of a part "identical" to the OE part. Because such parts would have been approved under UN R13/13-H, they were exempted from redundant approval under R90. This proposal would similarly define and exempt brake linings. | ||||||||

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. |
