Anti-Lock Brake System (Abs) Road Test Evaluation Procedure for Trucks, Truck-Tractors and Buses

2002-02-07
HISTORICAL
J2536_200202
Test procedure for Anti-Lock brake system (ABS/Anti-Lock) performance for on-highway commercial vehicles over 4536 kg (10 000 lb). This test procedure is intended to determine vehicle stability, maneuverability, stopping capability and system function on various road surface conditions including variable and uniform friction surfaces while brakes are modulated to obtain maximum performance with activation of ABS/Anti-Lock. This procedure does not cover radio frequency interference or power consumption testing. Reference SAE J46 Wheel-Slip Brake Control Road Test Code for passenger car and light truck test procedure.

J992_199812
This SAE Recommended Practice presents performance requirements for the brake systems of motor vehicles intended for roadway use and falling into the following classifications: Light trucks and buses: 6001-10 000 lb (2700-4500 kg) gvw; Truck and bus: Over 10 000 lb (4500 kg) gvw; combination of vehicles towing vehicles over 10 000 lb (4500 kg) gvw. Acceptable performance requirements are based on data obtained from applicable sections of SAE J786a (March, 1978). The purpose of this recommended practice is to establish the minimum brake system performance requirements with regard to: 3.1 Stopping ability--of cold brakes, as affected by vehicle speed. 3.2 Stopping ability--of hot brakes, as affected by vehicle speed and duty cycle. 3.3 Pedal force (air pressure) requirements--maximum allowable. 3.4 Brake stability. 3.5 stopping ability and recovery of wet brakes. 3.6 Stopping ability of emergency brake system. 3.7 Brake effectiveness distribution for vehicles in combination.
