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).

Applicable to test pieces cut from products of cellular materials. Useful for two purposes: a) studying the structure of cellular products in connection with their physical properties and their method of manufacture and b) ensuring product quality (quality assurance). Describes principle, apparatus, test piece and conditions, procedure and calculation and expression of the results. Three figures deliver the details for testing.

Defines a method measuring the peak deceleration of a mass when it is dropped on a test piece. The test described is intended primarily for quality assurance; however, an annex contains notes to be considered if the test is used to obtain design data. Two figures show typical arrangements.

Specification of the characteristics and the choice of the measuring equipment and procedure for determination of the linear dimensions of sheets, blocks or test specimens of ceelular material (flexible and rigid). Depending on the range of the dimensions to be measured different measuring instruments are recommended.

Specifies the determination of loss in thickness and loss in hardness of materials intended for use in upholstery. Provides a means of assessing the service performance. The method is applicable both to standard size test pieces cut from stock material and to shaped components. Formulas are given to express the loss in thickness and the loss in hardness. Two figures show the details of a manually adjusted machine and an automatically adjusted. Constitutes a minor revision of the second edition (ISO 3385:1982).
