- Scope
- This part of ISO 3386 specifies a method for the
determination of the compression stress-strain
characteristics of flexible cellular polymeric
materials of density greater than 250 kg/m3.
The compression stress-strain characteristic is a
measure of the load-bearing properties of the
material, though not necessarily of its capacity to
sustain a long-term load.
The compression stress-strain characteristic differs
from the indentation hardness characteristics
(as determined in accordance with ISO 2439) which
are known to be influenced by the thickness and the
tensile properties of the flexible cellular material
under test, the shape of the compression plate, and
the shape and size of the test piece.
ISO 3386-1 specifies a method for low-density
flexible materials, and differs from Part 2 in the
following ways:
- Part 1 is concerned with materials of density
up to 250 kg/m3, whilst Part 2 is mainly
concerned with materials of density
above 250 kg/m3;
- compression stress values have been deleted
from Part 2;
- Part 2 does not allow the use of a cylindrical
test piece.
This part of ISO 3386 is a general method for testing
denser flexible cellular materials
(i.e. expanded cellular rubbers), measurements
being made on one of more points on the steeply
rising part of the stress-strain curve. The shape
factor of the test piece is important and comparative
test results can only be obtained on test pieces
having the same shape factor.
