ASTM D3574 X6 | Foam | Compression Testing
ASTM D3574 is a commonly used standard for tests involving flexible cellular foam materials. ASTM D3574 X6 specifies a method for measuring the hysteresis energy loss of foams. Hysteresis loss is defined as the difference between the loading energy and the unloading energy expressed as a percentage of the loading energy. This analysis will help to better characterize and compare various foams and determine their ideal applications. The test may be performed as either an Indentation Force Deflection (IFD) test, or as a Compression Force Deflection (CFD) test.
Prior to conducting ASTM D3574 X6, it is important to read the entire specification in the relevant ASTM publication.

- Prepare and preflex samples in accordance with ASTM D3574 Test B1 (IFD) for samples with area larger than the indenting platen. For samples with area smaller than the compression platen, prepare and preflex samples in accordance with ASTM D3574 Test C (CFD).
- Wait 6 ± 1 minutes after preflex to allow foam sample to rest.
- Indent the sample at the rate specified in the standard.
- Immediately remove the indentation force at the same rate as the initial indentation.
