18. The expert from CLEPA introduced GRRF-81-07, proposing the procedure to identify allowable combinations of performance values Dc and V for drawbar coupling equipment. The expert from the UK noted that an editorial correction would be needed in paragraph 4.1.1. and proposed to assist the Secretary of the IWG to prepare an official document for consideration at the next GRRF session.

Mr. Lescail remarkerd that in the consolidated document the angle denomination on page 10 shall be in Greek characters. The formula on page 8 shall be stricken through.

There was a general discussion on consolidated documentation with respect to the different regulations and in our case specifically on regulation 55. It was noted that since our last meeting the secretary of GRRF had published a second revision of regulation 55. This was well received by the working group. It was challenged why that could not be done in general instead of issuing amendments.

There was also a short information that the secretary of our working group had made a further consolidation in the working documents R55-12-01 and R55-12-02 just in order to keep track of a correct numbering in forthcoming proposals.

This item was agreed at our Poznan meeting. To our October meeting it was included in the proposal for Item 21. In order to make each proposal easier to comprehend it was now separated out. It was subject to the same principle discussion as Item 20. It was agreed to submit this proposal as an informal document to the GRRF 81.
