Product Code:SAE J2521
Title:Disc and Drum Brake Dynamometer Squeal Noise Matrix
Issuing Committee:Brake Nvh Standards Committee
Scope:This procedure is applicable to high frequency squeal type noise occurrences for passenger car and light truck type vehicles that are used under conventional operating conditions. The procedure does not encompass the consequences associate with changes in environment relate to temperature and humidity variations.PurposeThis recommended test practice is intended to establish a common universally recognized method for performing a series of screening test sequences that identify the propensity of a brake assembly to generate squeal noise under a variety of test conditions.
