Véhicules routiers — Véhicules à moteur et véhicules tractés disposant de systèmes de freinage d'endurance — Procédures d'essai

ISO 12161:2006 specifies methods for testing the endurance braking systems of vehicles of categories M, N and O (excluding M1, N1, O1 and O2), which are designed to comply with ECE-R 13/09 with supplements 1 to 6.

All endurance test procedures are based on the principle of equivalent energy absorption. Procedures which are not suitable to support this principle are not considered.

The principle of equivalent energy allows the base test parameters to be adapted to the variations occurring under real conditions compared to theoretical values.
