1.1 This practice covers the basic test procedures for determination of the physical properties and reporting of data for high-density rigid cellular plastics.

1.2 The values stated in SI units are to be regarded as standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Note 1This standard and ISO 9054 address the same subject matter, but differ in technical content.

This practice covers the basic test procedures for the determination of the physical properties and the reporting of data for high-density rigid cellular plastics. Samples shall be prepared by either processing samples directly into proper size specimens, or by preparing samples from larger sections as specified in each individual test. Since cellular plastics are often nonuniform in density distribution, a minimum of five specimens shall, therefore, be tested per testing method to obtain representative values. The test methods covered here are to examine the following material properties: apparent density; compressive strength; tensile properties; coefficient of linear thermal expansion; apparent flexural properties; deflection temperature; dielectric breakdown voltage and dielectric strength; thermal conductivity; and water absorption rate.
