Rigid cellular plastics - Determination of compression properties

Organization: ISO
Publication Date: 1 August 2014
Status: active
Page Count: 16
ICS Code (Cellular materials): 83.100
scope:

This International Standard specifies a method of determining:

a) the compressive strength and corresponding relative deformation, or

b) the compressive stress at 10 % relative deformation, and

c) when desired, the compressive modulus of rigid cellular plastics.

There are two procedures:

- Procedure A employs crosshead motion for determination of compressive properties. Procedure A is intended to be used when compressive stress at 10 % relative deformation has to be determined.

- Procedure B employs strain measuring devices mounted on the specimen (contact extensometer) or similar device which measures directly sample deformation. Procedure B is intended to be used when compressive modulus has to be determined.

NOTE Compressive strength (at maximum load) can be determined either with Procedure A and B.
