This SAE Recommended Practice establishes a method of testing the structural integrity of the brake system of all new trucks, buses, and combination vehicles designed for roadway use and falling in the following classifications: aTruck and Bus—Over 4500 kg (10 000 lb) GVWR bCombination vehicle—Towing vehicle over 4500 kg (10 000 lb) GVWR The test consists of two distinct tests: a Structural Endurance Test followed by a Structural Ultimate Strength Test.

This SAE Recommended Practice establishes a method of testing the structural integrity of the brake system of all new trucks, buses, and combination vehicles designed for roadway use and falling in the following classifications:aTruck and Bus—Over 4500 kg (10 000 lb) GVWRbCombination vehicle—Towing vehicle over 4500 kg (10 000 lb) GVWRThe test consists of two distinct tests: a Structural Endurance Test followed by a Structural Ultimate Strength Test.NOTE—These two tests originated from separate procedures, and were combined in this Recommended Practice. Each test can be considered to be an independent evaluation of the service brake’s structure. Based on time available, cost limitations, and the desired evaluation and historical data available, either of these tests could be considered as a complete evaluation of the brake’s structure.
