The indentation hardness of flexible cellular materials is a measure of their load-bearing properties. This
International Standard specifies four methods (A to D) for the determination of indentation hardness and one
method (E) for determination of compressive deflection coefficient and hysteresis loss rate of flexible cellular
materials. Annex A provides a summary of test parameters and typical force-indentation graphs obtained with
these methods.
These five methods are applicable only to latex foam, urethane foam and PVC foam of the open-cell type. The
methods specified can be used for testing finished articles and for the characterization of bulk material.
