- This SAE Recommended Practice is intended for qualification testing for brake drums used on highway commercial vehicles with air brakes using an inertia-dynamometer procedure.This document consists of two distinct tests: Part A, durability and speed maintenance test, and Part B, heat check drag sequence test. Each test can be considered to be an independent evaluation of the brake drum which tests different properties.

- The previous version of this SAE Recommended Practice referenced a standard (FMVSS 121) that is out of date. This revision removes the date of the document, allowing the reference document to be the current level of FMVSS 121.
