8. The expert from Denmark presented documents relating to truck and trailer brake compatibility, coupling force control, and test points for Periodical Technical Inspections (PTI). The documents included GRRF-72-26 underlining the need to improve brake distribution between the truck and the trailer of heavy vehicle combinations. He introduced GRRF-72-07 supplementing his proposal ECE/TRANS/WP.29/GRRF/2012/12. GRRF noted a number of concerns raised the experts from CLCCR, CLEPA and OICA (GRRF-72-18, GRRF-72-19, GRRF-72-21 and GRRF-72-20). 9. Following the discussion, GRRF welcomed the initiative by the industry to hold an ad hoc expert meeting on this issue in order to consider the issues, jointly with the experts from Denmark and other interested experts, and to report back at the next session of GRRF. The expert from OICA offered to host the meeting in June 2012. |
