    The following results of TFAC are presently achieved:
  • TFAC 02-13 (Basic document)
  • TFAC 03-04 Rev. 1 (CUNA-Couplings, Class q and r)
  • TFAC 03-08 Rev. 1 (Drawbar, Class i)
  • TFAC 03-10 Rev. 1 (Class j to become a, Class k to become b, Towing brackets)
  • TFAC 03-14 (Mounting height of coupling on the tractor)
    Still open and further need for discussion concerns:
  • TFAC 03-13 (Swedish proposals)
  • TFAC 04-09 (Italian Proposal for Annex 5)
  • TFAC 04-04 and TFAC … (Results of the small group)

Mr Schauer is asked to prepare a complete document with the agreed changes on the basis on R 55 until End of April (to become TFAC 04-11). Members of TFAC are invited to submit their comments four weeks after submission of that document.

It was agreed to present the results of TFAC to the IWG R 55 in the next meeting to be held in Poznan beginning of June by Mr Schauer and Mr Pagliarani.

3.6 Vehicle approval according to Chapter 5 possible?

A vehicle approval for category T vehicle is possible. As R and S categories are not yet defined in R.E.3, vehicle approvals are currently not possible. As soon as those definitions are adopted, the scope of R 55 shall be extended accordingly. Mr Schauer will add the requirement for the mounting height of couplings on tractors to chapter 5 (already done, see TFAC-03-14).
