Proposal to remove the clause in annex 6 that stipulates different technical requirements for mechanical couplings to be used on agricultural tractors with a maximum speed in excess of 60 km/h in order to promote a common understanding of the technical requirements (i.e., reduce differences due to divergent interpretations of the clause).

Proposal to remove the possibility of different technical requirements being applied by Type Approval Authorities when mechanical couplings for agricultural tractors with a maximum speed in excess of 60 km/h are submitted for type approval testing. The amendment would align requirements with European Union approvals which are accepted to be technically correct in design and safe to use at all speeds. This is achieved by the removal of the clause in annex 6 that requires different technical requirements for mechanical couplings to be used on agricultural tractors with a maximum speed in excess of 60 km/h.

Proposal for a new UN Regulation on uniform provisions concerning the approval of mechanical coupling components of combinations of agricultural vehicles. [Regulation adopted with Australia and Japan abstaining.]

Report of the expert group on agricultural coupling devices and components on the development of a new UN Regulation.

Formal proposal from the ACDC informal group for consideration by GRRF for a new Regulation on uniform provisions concerning the approval of mechanical coupling components of combinations of agricultural vehicles.

Correction of a reference used in the original proposal for a new UN Regulation on agricultural vehicle couplings. In Annex 6, paragraph 1.7., 3.3.6. and 3.7.1.: The Term F_s is not needed and misleading. The vertical component of the test force is named F_v. This term should be used throughout the whole document concerning the vertical component of the test forces.

Comments on the draft as of 10 January 2017.

Incorporating editorial changes from the first ACDC informal group meeting.

One of the outcomes of the work on updating UN R55 was the recognition that agricultural couplings present a set of challenges distinct from other vehicles. This revised proposal takes into account comments received during the February 2016 GRRF session for the establishment of an informal working group to develop a new regulation (UN R55-A) to respond to the specific needs of agricultural vehicle couplings.

One of the outcomes of the work on updating UN R55 was the recognition that agricultural couplings present a set of challenges distinct from other vehicles. Therefore, Germany proposes the establishment of an informal working group to develop a new regulations (UN R55-A) to respond to the specific needs of agricultural vehicle couplings.
