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.
17. The chair of the IWG on UN Regulation No. 55 introduced GRRF-78-23 explaining the differences between standards ISO 7641:1983 and ISO 7641:2012. He reported on the meeting minutes (GRRF‑78‑25) and on the meetings status on Task Force Agricultural Couplings (TFAC) (GRRF‑78‑26). Finally he presented GRRF‑78-24 as a complete revision of UN Regulation No. 55. GRRF agreed to resume consideration of this proposal at its February 2015 session.
