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. The gauge is equipped with the Memory Pointer 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.”
