The waiting list

According to the discussion on the future of this informal working group, the waiting list items are activated.

Item w1 (Approval based on worst case class B50x)(R55-07-19)
Mrs. Domagala presented document R55-10-19 as a proposal for this item. This was elaborated in the document R55-10-20. The French delegates argued that the last sentence of §1.1.1 might not be necessary. Mrs. Domagala was asked to rewrite the justification. (During a coffee break Mrs. Domagala and Mr. Svensson outlined an alternative justification as in R55-10-20. This was not reviewed by the group and Mrs. Domagala shall elaborate to the next meeting

Item w2 (Approval based on worst case class B50x)(R55-07-19)
This matter was dropped.

Item w3 (Alternative performance values)(R55-10-22)
KBA request a more stringent definition of alternative performance values. The base proposal assumed alternative values for a single component. However Mr. Westphäling showed that it is more to this than that. When broaden the scope to a family or range of products this becomes more complex. Mr. Hansen and Mr. Westphäling was assigned the task to outline a new proposal for the broader scope to the next meeting.

Item w7 (Class H50)( )
KBA requests to add a class H50 which seems missing. Considering the reference to the king-pin drawing in annex 5 Mr. Svensson argued that it might be such that the existing class H50-X is not really motivated. I.e. the class H50 –X shall be replaced by the class H50. Mr. Hansen will check this up to the next meeting.

Item w8 (Wedge angle)( R55-09-20)
Mr. Tagliaferri requested the drawing of the wedge in annex 5 §7.8.1. to changed. The changed drawing is shown in document R55-09-20. This was agreed.

Due to lack of time the remaining item were left to be processed later meetings.

Report from TFAC
Mr. Schauer made a report from the work in the TFAC.

First of all Mr. Schauer reported that compromises had been reached on all open technical issues.

Then he put forward a proposal from the taskforce that they considered to have the agricultural coupling regulation as a separate regulation. Mr. Westphäling was not at all in agreement with this proposal. The discussion on this item was long and intensive. The discussion resulted in an agreement that a fully elaborated proposal where the agricultural rules are integrated together with the rules for commercial vehicles. At least a sketch for a separate regulation shall be elaborated at the same time. These two documents shall be submitted to the GRRF for guidance. While elaborating the agricultural rules it should be born in mind that the number of coupling equipment classes shall be minimized. The concept from the commercial vehicles could serve as guidance in this effort. I.e. most of different installation alternatives can be handled in the annexes (for commercial vehicles annex 5) rather than in the definitions. Further the need for a new annex 1 resulting in annex 1A and 1B shall be challenged. May be a minor alteration to the existing annex 1 would be sufficient.

Approach towards the 80th session of the GRRF
Agreed items shall be put in a form such that a working document could be compiled to the deadline for the 80th session of the GRRF. Informal documents will be compiled to address agreed changes to the submitted working documents.
