UN / ECE R 69 Tests

UN ECE R69 tests cover a series of tests performed in accordance with the relevant regulation for the evaluation of M, N, O and T category vehicles in terms of rear marking plates.

ECE regulations define cross-border technical regulations for establishing approval or uniform approval procedures for motor vehicles and motor vehicle parts. Automated commercial vehicles are already fully eligible for approval only through appropriate individual measures in the country in which they will be used. What is missing is a set of rules at the international ECE level.

Regulation 69 of the United Nations Economic Commission for Europe (UN/ECE) — Covers the uniform provisions for the approval of rear marking plates for slow-moving vehicles (by construction) and their trailers, and the tests applied accordingly.

This Regulation applies to rear marking plates for vehicles of category M, N, O and T and for mobile machinery which by construction cannot travel faster than 40 km/h. Within the scope of the regulation, the relevant equipment must meet the following;

• SMV rear marking plates shall be constructed to function satisfactorily and function in normal use. In addition, they will be free of design or manufacturing defects that would impair their efficient operation or maintenance in good condition.
• Components of retroreflective/fluorescent SMV rear marking plates (class 1) or retroreflective only SMV rear marking plates (class 2) will not be easily removable.
• The means of attachment of the SMV rear marking plate must be such as to allow a stable and durable connection between the plate and the rear end of the vehicles, for example, with screws or rivets.
• The outer surface of the retroreflective/fluorescent SMV rear marking plate (class 1) or the retroreflective SMV only back marking plate (class 2) will be easy to clean. For this reason, the surface will not be rough and the protrusions it may exhibit will not prevent easy cleaning.
• SMV rear marking plates must also meet the requirements for dimensions, shape, pattern and colorimetric, photometric, physical and mechanical requirements set out in Annexes 5 to 12 of this Regulation.

Within the scope of the regulation, many mechanical, dynamic and environmental tests are carried out as well as measurements for the approval of the relevant equipment. For tests to be considered successful, test results must meet regulatory requirements.
