Proposal by the informal working group on Regulation No. 55 to amend the definition of Class S couplings.

Proposal draft by the informal group on UN Regulation No. 55 to update this regulation with respect to:
a) Requirements on remote indication;
b) Availability of information on coupling fixing points for A50X couplings;
c) On lateral strength of drawbars; and
d) a new class definition for fully automatic drawbar couplings.

Proposal to introduce amendments to the test procedure and installation requirements of couplings belonging to classes K and L.

Report of the task force on agricultural vehicle couplings.

Second revision of the draft text proposing to introduce amendments on the test procedure and installation of couplings belonging to classes K and L.

Report from the meeting of the Small Group for definition of Formulas and Test procedure for agricultural towing devices.

Class S couplings refer to non-standard national/regional couplings that remain in use despite the broad trend towards harmonization around an agreed set of couplings specifically covered by other UN R55 classes. The aim of this proposal is to tighten and clarify the requirements for such couplings while discouraging the development of new non-standard Class S couplings (such that new designs would result in new classes if needed).

Working draft proposal from the informal group on Regulation No. 55 to update the provisions concerning Class K hook-type couplings when coupled with class L toroidal drawbar eyes.
