1 SCOPE.

This specification covers the material properties and durability requirements of a flocked fabric, felt, or nonwoven sound abatement tape. These tapes are used for interior sound abatement applications where 2 similar or dissimilar substrate materials come into contact causing a rubbing, chaffing, itching, chattering, rattling, or squeaking noise. Typical areas of application are between interior trim parts, instrument panel components, and other areas depending on the origin of undesired sound. In most cases, the tape ends up being trapped between 2 surfaces.
