R55-12-05 | UN R55: Working draft proposal for allowable performance values
Proposal under preparation for the GRRF by the R55 informal group. This proposal concerns a procedure to identify allowable combinations of performance values Dc and V for drawbar coupling equipment. This proposal would amend the Revision 2 proposal for UN R55.
R55-12-19/Rev.1 | UN R55: Revised working draft proposal for allowable performance values
Proposal as developed by the UN R55 informal group during its 12th session. This proposal concerns a procedure to identify allowable combinations of performance values Dc and V for drawbar coupling equipment. This proposal would amend the Revision 2 proposal for UN R55.

|
| 5.7. | Item 25 (Articulation angles as installed) |
R55-12-06 | Minimum articulation angles for vehicle couplings
UN R55 does not include provisions for minimum articulation angles of couplings. However, couplings may be damaged if a vehicle combination takes a narrow curve or other maneuver that exceeds the coupling design. In order to prevent coupling failures, this proposal suggests minimum articulation requirements based partly upon ISO 1726-1 and 11407 for drawbar and fifth wheel couplings.

GRRF-80-29 | Proposal for a Supplement to the 01 series of amendments to Regulation No. 55
Proposal to ensure that coupling balls do not block rear lighting and/or registration plates. In line with the EU General Safety Rule, Annex IV specification for application of UN R55, couplings that might block lighting or plates must be removable, repositionable, and unlockable in order to make it easier for users to remove them or reposition them when not in use (e.g., towing a trailer.) Coupling balls that are so designed as to be unable to block lighting or plates may still incorporate locks and/or require tools to remove or reposition.
