UN ECE R146 tests cover a series of tests carried out in accordance with the relevant regulation for the safety evaluation of hydrogen fueled vehicles in the categories specified in the regulation.
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 146 of the United Nations Economic Commission for Europe (UN/ECE) — Uniform provisions for the approval of motor vehicles and their components with respect to the safety-related performance of hydrogen fueled vehicles in categories L1, L2, L3, L4 and L5, and the corresponding applicable includes tests.
Hydrogen-fueled vehicle means any motor vehicle that uses compressed gaseous hydrogen as fuel to propel the vehicle, including fuel cell and internal combustion engine vehicles.
This Regulation does not cover post-collision safety requirements for road vehicles and applies to:
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.
