Description / Abstract:

This procedure describes a method for measurement of dust-out from fiber sound absorber pad. It applies to both needled and resin-bonded constructions, and to unfaced as well as coated and film-covered materials. The combined dust-out from material surface and cut edge is measured. This procedure is intended for use in assembly plants and/or for production quality control.

NOTE: Fiber sound absorber pad is inherently a variable, commodity product. Therefore, large variations in dust-out are to be expected from lot to lot and even part to part. These variations in dust result from raw material composition variability and handling of finished goods. Caution should be used in applying this procedure and ratings to minimization of dust. While continuous improvement in material dust-out can be expected through specification-driven process improvements, total freedom from dust is not feasible without significant material cost increase.
