Scope

This standard specifies three methods for determining the indentation hardness of flexible cellular
materials:
— Method A: indentation hardness index, which gives a single indentation measurement for
laboratory test purposes;
— Method B: indentation hardness characteristics, which provides information about the
shape of the hardness indentation curve;
— Method C: indentation hardness check, which is a quick procedure suitable for quality
control testing.
The methods are applicable only to latex, urethane foam and PVC foam of the open cell type.
The results obtained by these methods relate only to the test conditions specified and cannot, in
general, be used directly for design purposes.
Note: The indentation hardness of flexible cellular materials is a measure of their load-bearing properties. The
methods specified can be used for testing finished articles and for the characterization of bulk material.
