UN / ECE R 116 Tests

UN ECE R116 tests cover a series of tests carried out in accordance with the relevant regulation for the evaluation of vehicles in the categories specified in the regulation in terms of unauthorized use and vehicle alarm systems.

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 116 of the United Nations Economic Commission for Europe (UN/ECE) — It covers the uniform technical guidelines on the protection of motor vehicles against unauthorized use and the tests applied accordingly.

UN ECE R116 Regulation covers the following;

• Approval of an M1 and N1 category vehicle for their device to prevent unauthorized use
• Approval of vehicle alarm systems (VAS) intended to be permanently installed on vehicles of category M2 and category N1 with a maximum mass not exceeding 1 tons
• Approval of vehicles of category M1 and category N2 with a maximum mass not exceeding 1 tons in relation to the alarm system(s)
• Approval of immobilizers for vehicles of category M1 and vehicles of category N2 with a maximum mass not exceeding 1 tons.

The device preventing unauthorized use shall be designed so that it must be deactivated to:

• the engine to be started by means of normal control; and
• the vehicle to be steered, driven or moved forward under its own power.

The device preventing unauthorized use must be fitted to the vehicle as part of the original equipment. Mechanical locking systems must provide at least 1000 different key combinations or, if less than 1000, a number equal to the total number of vehicles produced annually. The frequency of occurrence of each combination in one type of vehicle will be approximately one in 1000.

Electrical/electronic locking systems, e.g. remote control, must have at least 50.000 variants and contain a rolling code and/or have a minimum scan time of ten days,

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.
