Description / Abstract:
Note: Nothing in this standard supercedes
applicable laws and regulations.
Note: In the event of conflict between the
English and domestic language, the English language shall take
precedence.
Purpose. This test procedure shall be used to
determine the indentation hardness of small elastic foam components
where the size of the component precludes the use of other standard
methods.
The results obtained by measurements on components of differing
shapes, or at different locations on the same component, or by the
use of different sized indentors are not necessarily
comparable.
Test results obtained by measurements on components of similar
shape, but of different structures (cellular, etc.), are comparable
provided measuring conditions are identical.
The indentation hardness is defined as the depth of penetration
(in millimeters) of a standard shaped indentor when pressed under
constant force into the foam component for 30 s, 60 s, or other
time as may be specified.
Applicability. Polyurethane (PUR) back foaming
Instrument panel, headrest, armrest, soft integral foam.
