Description / Abstract:
Provide description of standard test methods, analysis methods,
and reporting methods for measuring the resonant modes of
automotive disc brake rotors and drums for purpose of design and
production verification of these components.
Purpose
This procedure may be used for verification of production
capability of a plant to produce brake rotors that are consistent
with Production Part Approval Process (PPAP). The procedure may be
used to fingerprint parts used for design validation process.
