Dynamometer Global Brake Effectiveness
J2522_201301
This SAE Recommended Practice defines an Inertia Dynamometer Test procedure that assesses the effectiveness behavior of a friction material with regard to pressure, temperature and speed for motor vehicles fitted with hydraulic brake actuation.
Rationale:
This revision includes changes to the cooling air speed for different sections in order to harmonize with other SAE inertia dynamometer test procedures, and to reflect standard testing practices from several laboratories which conduct the test on a regular basis. As this Recommended Practice is widely used in the industry, these changes will help increasing the test efficiency without compromising the technical consistency and relevance during product development, release, validation, and ongoing product monitoring.
