Document GRRF/2017/3

14 November 2016

83rd GRRF session (23-27 Jan 2017)

UN R55 informal group proposal for:

An amendment for the separation of the procedures to verify towable mass from the procedure of setting and certifying performance values;
An amendment that adds procedures to verify towable mass for vehicle combinations that have hitherto not been accounted for in the Regulation;
Amendments that adds integrated fixing points for secondary couplings;
An amendment that clarifies the procedure to identify worst cases for certification testing;
Amendments that removes typos in the current Regulation.

Please note that, under paragraph 3.4 regarding “Combination 4”, the Clevis coupling formula should read “D_C” rather than “D” as shown.
