Rigid cellular plastics - Determination of compressive properties

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.
