Rationale

OEMs are asking for compression curve data more often as engineers are using these curves to compare and identify materials to use in their applications. There is not a standard method for preparing compression curves and the associated data from them as current flexible cellular material methods only call for singe stress measurements at a specified strain. Foam producers are supplying curves to OEM’s but specimen dimensions, test speed and presentation of results are not consistent and may not provide good comparisons between products.
