3.1 Review common proposal based on TFAC 03-06 from the small group (Doc. TFAC-04-04 and TFAC-03-06)

The small group held its first meeting on 18 December 2013 (minutes see TFAC-04-04). There are still some open issues which will be discussed and solved during a second meeting on 6 March 2014.

3.4 Discussion and decision on TFAC-03-13

Mr Duffy explained TFAC 04-07 with regard to the Sewdish proposals (TFAC-03-13). It was decided to continue the discussion in the IWG R55.

3.5 Review of present R 55.01 including Corr. 1 and Amend. 1–3 and the proposals for amendment and conclusions for these amendments (GRRF/2013/16, GRRF-75-21 and GRRF/2014/14)

    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.

5.2 Italian Proposal for Annex 5 (TFAC 04-09)

Mr Pagliarani explained the background and the Italian proposal on Annex 5. It was agreed to upload the document to the TFAC website and to ask for comments on it by the members of TFAC.

For information, the comments of Italy on the draft EU-Regulation RVFSR are given in TFAC 04-10.

5.3 Discussion static versus dynamic testing

With a presentation (TFAC 04-08) Mr Westphäling explained the reasons why according to his opinion a static testing of coupling devices should not be permitted.

Mr Rehm and Mr Pagliarani expressed the opinion that a static testing should be permitted for the “CUNA-Couplings” and the drawbar up to 40 km/h max. speed as these devices are tested statically for decades in Europe and no failures or accidents are known so far.

Mr Gunneriusson supported the opinion of Mr Westphäling.

After a detailed discussion, the majority of the participant could accept the position of Mr Rehm and Mr Pagliarani. It was decided that the IWG R 55 should discuss this topic during one of their next meetings.
