Proposed text for determining worst case conditions for physical testing of couplings.

At the May 2015 Type Approval Authorities Meeting (TAAM), Poland raised concerns (attached with this submission) over small M₁ vehicles being equipped with aftermarket coupling devices where the vehicle in question is not designed for towing a trailer. In effect, these vehicles are not permitted to tow trailers, but are nonetheless enabled to be equipped for such a purpose by the aftermarket devices. Therefore, Poland proposes to amend UN R55 to ensure that coupling devices are only approved for use on vehicles approved for towing trailers.

Proposal to introduce a new optional “Class B1” headlamp. The proposal would establish photometric requirements for Class B1 based on average real performance of present Class B (halogen/LED) but would not include additional design restrictions such as the luminous flux of light source.

Proposal to restrict component type-approval for mechanical coupling devices dedicated to category M1 vehicles to use only on such M1 vehicles as are designed to tow trailers.

Proposal concerning document GRSG/2015/22 to clarify the specification of the abrasion test machine.

Proposal to clarify the definitions of LPG container accessories to facilitate coordination between the separate, independent approvals required for the LPG container and for its accessories. The proposal does not introduce any changes in technical requirements or changes in the test methodology. The proposed changes are intended to prevent the possibility of improper selection of accessories for the tank, which could arise due to lack of clear provisions of type-approval certificates issued for accessories fitted to the container.
