Rigid cellular plastics - Determination of compression properties (ISO 844:2014)

Status: Valid

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.
