1. OPERATION
a. The test specimen should be at least 6mm (0.25”) in thickness for the Shore A models and
at least 3mm (0.12”) in thickness for the Shore D models.
b. The lateral dimensions of the specimen should be sufficient to permit measurements at least
12mm (0.5”) from any edge.
c. The surface of the specimen should be flat and parallel over a sufficient area to permit
thepresser foot to contact the specimen over an area having a radius of at least 6mm
(0.25”)from the indentor point.
d. A specimen may be composed of plyed pieces to obtain the necessary thickness, but
determinations made on such specimens may not agree with those made on solid
specimens because the surface faces between plyes may not be in complete contact
1.1 Testing procedure
a. Ensure the tester is set to zero before commencing any tests.
b. Change to REF I mode when using the durometer.
c. Place the specimen on a hard, horizontal surface.
d. Hold the durometer in a vertical position with the point of the indentor a least 12mm (0.5”)
from any edge.
e. Apply the presser foot to the specimen as rapidly as possible, without shock, keeping the
foot parallel to the surface of the specimen. Apply just sufficient pressure to obtain firm
contactbetween presser foot and specimen.
f. The hardness should be read off 1 second after the presser foot of the durometer has made
contact.
g. In case of the specimen exhibiting a marked flow propensity, the reading may also be
taken after 15 seconds.
1.2 Using the supplied aluminium reference block
To check the tester has not been damaged simply place the
indentor of the tester in the slot of the test block. Apply gentle
pressure keeping the tester vertical, then simply read off the value
obtained. This should be within ±2 units.
Please note:
INNOVATEST Europe BV recommend that the unit is returned
annually for re-calibration.
