Polymeric materials, cellular flexible - Determination of stress-strain characteristic in compression - Part 1: Low-density materials (ISO 3386-1:1986)
Covers the determination of material 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 to calculate the results. Part 2 refers to high density materials. Constitutes a minor revision of the first edition (ISO 3386/ 1-1979).
