Brake System Rating Test Code-Commercial Vehicles

1980-02-01
HISTORICAL
J880_198002
This code is intended for commercial vehicles over 4500 kg (10 000 lb) with brake systems having typical service pressure ranges 0 to 14.1 mPa (0 to 2050 psi) hydraulic or 0 to 830 kPa (0 to 130 psi) air and is not directly applicable to vehicles with other systems. Air over hydraulic systems are to be tested as air systems.

J880_198503
This code is intended for commercial vehicles over 4500 kg (10 000 lb) with brake systems having typical service pressure ranges 0 to 14.1 MPa (0 to 2050 psi) hydraulic or 0 to 830 kPa (0 to 120 psi) air and is not directly applicable to vehicles with other systems. Air over hydraulic systems are to be tested as air systems. The code provides test procedures and instructions for: a. instrumentation and equipment; b. vehicle preparation; c. determining brake system energy absorption capacity; and d. calculation of brake rating. The purpose of this code is to provide a method for determining a brake system rating for new commercial highway vehicles, based on the energy absorption and dissipation capacity of the brake system as established by a repeated test procedure. For performance requirements, refer to SAE J257 (FEB97).
