Testing Procedure

1. Place the instrument on the material to
be tested. The durometer must be level
and perpendicular to the specimen.
Any angle other than perpendicular
(90°) may cause errors.
NOTE: If the gauge is equipped with the
Memory Pointer option make sure the
pointer is returned to zero before starting.
2. Press the foot of the gauge firmly
against the specimen, but not so
firmly as to imbed the foot into the
surface of the material.
3. Maintain pressure for 2 to 3 seconds.
The dial hand gives the reading in
durometer points.
ImPOrTaNT: After the initial reading has been noted, continue
maintaining pressure for several more seconds. Creep or cold-flow of the
specimen, if present, will be evident by receding action of the dial hand.
4. Repeat above steps for each use.
An example of a properly noted durometer reading:
"Durometer A 61, Creep 7 at 15 seconds, 73°F."
