3.1 Proposal for Class q and r (CUNA Couplings) (Doc. TFAC-03-04)

The slightly modified proposal was accepted. Modifications are indicated in red in document TFAC 03-04 Rev 1. The allocation tractor coupling/trailer coupling should be inserted in Annex 2.

There is a common agreement to reduce the number of different coupling devices at a later stage.

3.2 Proposal for Class I (Documents TFAC-03-08 and TFAC-03-07)

The slightly modified proposal was accepted. Modifications are indicated in red in document TFAC-03-08 Rev 1.

3.3 Proposal to transfer Class j to Class a and Class k to Class b (Document TFAC-03-10)

The proposal was accepted.

3.4 Proposal for the definition of tractor drawbars and their hitch rings in an own Class (Documents TFAC-03-08 and TFAC-03-07)

See 3.2. above.

3.5 Comparison of proposals Va and V (Documents TFAC-02-08 and TFAC-03-06)

The majority of the participants are in favor to keep the current formulas for D and Dc values.

It was agreed to establish a small group (Mr. Inverardi, Mr. Afflerbach, Mr. Conrads, Mr. Duffy and Mr. Stokreff) to make a common proposal based on document TFAC-03-06 for the next meeting.

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).

3.7 IT-Proposals for Annex 4 (Document TFAC-03-05)

The slightly modified proposal was accepted. Modifications are indicated in red in document TFAC-03-05/Rev 1.

3.8 Proposal for Chapter 6 of Annex 5 (Document TFAC-03-10)

The slightly modified proposal was accepted. Modifications are indicated in red in document TFAC-03-10/Rev1. Mr Westphäling will review 6.1 and will make a proposal for the next meeting.

3.10 arguments to keep current EU legislation (static test) (Document TFAC-03-03)

The group could not reach a consensus on this topic. It was voted on the following four options:

  1. Static test optional only for Classes i and q and a maximum speed not exceeding
    40 km/h: 1 in favor.
  2. No inclusion of the static test but allow to grant approvals based on static tests in a transitional period up to 01.01.20XY (tbd): 2 in favor.
  3. Static test optional for all Classes and a maximum speed not exceeding 40 km/h: 10 in favor.
  4. Static test optional only for “simple constructions” but without speed limit: 5 in favor.

It was agreed to report this result in GRRF and leave the decision up to GRRF.

5.1 Swedish proposal (Document TFAC-03-13)

Mr Gunneriusson explained the proposal and the background. It was agreed that the participants shall review TFAC-03-13 for discussion and decision at the next meeting.

The participants introduced themselves (see also Document TFAC-03-12).
