Compression Force Deflection (CFD) of Flexible Polyurethane Foam per ASTM D3574 Test C

ASTM D3574 Test C and ISO 3386 both measure the force deflection properties of flexible polyurethane foam at a constant test speed, or rate of extension (CRE). The test is setup to measure the force required to compress the test sample to a level of 50 per cent of thickness. The sample is placed between two compression platens that are larger than the sample size. Note that the two standards are similar but not the same. The Compression Force Deflection test type, CFD for short, involves a preflex
