Introduction
Note: Nothing in this standard supercedes
applicable laws and regulations.
Note: In the event of conflict between the
English and domestic language, the English language shall take
precedence.
Purpose. To implement a worldwide uniform
process for evaluating the Squeak and Rattle (SR) performance
of a complete vehicle. This includes the detection, the evaluation
(by subjective rating of SR complaints), as well as some root
source analysis. Furthermore, the documentation of SR
complaints and the results of the root source analysis are
described for initiation of problem resolution. This procedure
consists of three (3) parts: Quasi-static evaluation(s), dynamic
road simulation evaluation(s) (where available) and dynamic on-road
evaluation(s).
This procedure also provides detailed instructions for
temperature evaluations using an environmental road simulator.
Applicability. For all passenger cars, light
commercial trucks and medium duty trucks.
Remarks. This procedure will guide an evaluator
through full vehicle SR evaluations. SR performance shall
be evaluated according to the GMW14264 subjective rating scale.
