Test N: Type-I Recovery performance
[Based on: ADR 31/01, Appendix A, Annex 3, Clause 1.5.4.]
This test is intended to check the performance of the brakes when hot.
The following general conditions apply:
• vehicles in Modification Category 16b shall be tested at 100 km/h
• vehicles in Modification Categories 17, 26 & 27 shall be tested at the lesser of 80% of
their maximum speed or 100 km/h
• vehicles in all other modifications categories shall be tested at 80 km/h
• the tests shall be done with the vehicle in the MLTM and LLTM conditions.
At the end of Test M (Type-I Recovery procedure) the recovery performance of the service
braking system shall be measured in the same conditions as for the Test J, Type-0 Engine
disconnected, (the temperature conditions may be different), using a mean force on the
Control, which is not more than the mean control force used in the corresponding Test J
(Type-0 Engine disconnected).
This recovery performance must not be less than 70%, nor more than 150%, of the figure
recorded for Test J.
