ISO 3386-1 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).
Scope and field of application
— it is mainly concerned with materials of density above 250 kg/m3;
— compression stress values have been deleted;
— it does not permit the use of a cylindrical test piece.
- ISO 1923, Cellular materials — Determination of linear dimensions.
- ISO 2439, Polymeric materials, cellular flexible — Determination of hardness (indentation technique).
