ISO 3386 Flexible cellular Foam Compression Stress-Strain

ISO 3386-1 - Lower Density Materials

ISO 3386-1 covers materials with a density up to 250 kg/m3. It also indicates a method for the calculation of the compression stress value of such materials. The compression stress/strain characteristic is a measure of the load-bearing properties of the material. Two formulas allow the results to be calculated.

ISO 3386-2 - High Density Materials 

ISO 3386-2 specifies a method for the determination of the compression stress-strain characteristics of flexible cellular polymeric materials of density greater than 250 kg/(m*m*m).The compression stress/strain characteristic is a measure of the load-bearing properties of the material.

ISO 3386 requires a universal test machine capable of compressing the test piece by means of a compression plate moving at a uniform rate of (5 +- 1) mm/min.
