M10-94400-1
ASTM F-36 outlines a standard procedure. This test is
not designed to indicate long term (creep) behavior and
should not be confused with the plastometer test.
Compression-Deflection Test.
Nondestructive method for determining relationship be-
tween compressive load and deflection under load for
vulcanized rubber. (ASTM D-575).
Compression Fatigue.
Ability of rubber to sustain repeated fluctuating compres-
sive loads. (ASTM D-623).
Compression Set.
The extent to which rubber is permanently deformed by
a prolonged compressive load (ASTM D-395). This
should not be confused with low temperature compres-
sion set.
Compression Test.
Method for determining behavior of materials under
crushing loads. Specimen is compressed, and deforma-
tion at various loads is recorded. Compressive stress and
strain are calculated and plotted as a stress-strain dia-
gram which is used to determine elastic limit, propor-
tional limit, yield point, yield strength and (for some
materials) compressive strength. Standard compression
tests are given in ASTM C-773 (high strength ceramics),
ASTM E-9 (metals), ASTM E-209 (metals at elevated
temperatures) and ASTM D-695 (plastics).
