Description / Abstract:
This test method is applicable for determining the relative
compression and recovery of fibrous insulation padding
materials.
Purpose
The purpose of this test method is to establish a means of
measuring the ability of fibrous insulation materials to resist
compression and recover after being compressed, dry or wet. It
should be noted that there are several test methods. These methods
have been found necessary for different loading applications,
variation in surface density of the padding materials and the
requirements of different vehicle manufacturers. The results of
these test methods cannot be correlated directly to each other. The
material specification should indicate which test is necessary for
a particular application.
