Rigid cellular plastics - Determination of compression properties
|Publication Date:||1 August 2014|
|ICS Code (Cellular materials):||83.100|
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.
