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