The group worked on the reduction of categories as requested by GRRF. The group deleted all subclasses and renamed the main classes accordingly so that the name includes the diameter (E.g. Category “a” became “a80”, subcategories a80-1,2,… were deleted). The definition of class “I” has been ameliorated and class “j” was added to include the drawbar eyes which are fitted to trailer drawbars for connecting to a tractor drawbar. The definition of the open category “S” has been ameliorated because the definition was too open (‘for example for special applications“ was deleted and a reference to international standards was added. The group asked CEMA to investigate which existing national and international standards exist. A discussion has been held on the possibility for truck couplings to be interchanged, but it was decided not to discuss the issue within the group but to discuss it at ISO level first, and to follow it up.

The group went through the document. A discussion has been held on “testing”, the group decided to discuss further the issue with the whole group. If no consensus is reached next meeting, a dedicated small group will be created. Another remaining point are the requirements for speed > 40km/h (test procedures, load presumptions, …). The group stressed that better/more figures and drawing should be added for each class of components. The group mentioned some other issues: table 4 (dimensions of standard flanges) should be ameliorated, resistance calculations are missing, there are no requirements for class “e”.

It was decided to circulate the document (ACDC-01-03e-Rev 1) and the group will be requested to
comment/ameliorate/add requirements using a common template (Comments-Template.xls). Answers should be given at the latest 2 weeks before the next meeting.
