Abstract / scope
This document specifies methods for determining the compressive strength, the corresponding compressive strain, the compressive stress at 10 % nominal compressive strain, and the compressive modulus of rigid cellular plastics.
Two procedures are specified. Procedure A and Procedure B.
Procedure A utilizes the compression plate displacement for the nominal property determination. It is used to determine:
- compressive strength and the corresponding nominal compressive strain;
- compressive stress at 10 % nominal compressive strain;
- nominal compressive modulus.
Procedure B uses an extensometer and determines the conventional properties. It is used to determine:
- compressive strength and the corresponding compressive strain;
- compressive modulus.
