GRRF-78-23
Comparison of ISO 7641:1983 and ISO 7641:2012

The expert group on UN R55 submitted document GRRF/2014/14 to update the requirements for mechanical couplings, including a proposal to replace the references to IS0 7641:1983 with ISO 7641:2012. In response to issues raised within GRRF, the experts prepared a new proposal (document GRRF/2014/28). This document would supplement the proposal by providing additional information on the differences between the 1983 and 2012 versions of ISO 7641.
