Scope

This standard specifies two test methods for determining the hysteresis loss properties
of flexible cellular polymeric materials.
- Method A: Determination of hysteresis loss by compression method;
- Method B: Determination of hysteresis loss by depression method.
This standard applies to the determination of hysteresis loss of flexible cellular
polymeric materials. Method A and method B in this standard are applicable to standard
size specimens, which are cut from block materials or molded specimens with various
shapes; method B is also applicable to molded products with various shapes.
