DUROMETER SHORE A
Hardness is one of the most significant physical properties of elastomeric
compounds. In one manner or another, it reflects such other qualities as
resilience, durability, uniformity, tensile strength and resistance to abrasion.
The Durometer Shore A is designed to measure the penetration hardness of
rubber, elastomers and other rubber like substances such as neoprene, silicone,
and vinyl. It can also be used for soft plastics, felt, leather and similar
materials.
The Durometer Shore A is built for the most
rugged materials, with all parts machined to a high tolerance for precision
gauge movement. All working parts are totally enclosed. Each heat-treated,
high carbon steel spring is calibrated to specified tolerances. A special
cam permits a scale deflection of 100 points when the indenter is displaced
exactly .1". The non-glare, brushed aluminum dial scale is extended
over 240 circular degrees to provide a reading accuracy well within 1% of
the calibration curve.
The lazy hand (ancillary pointer) is held by a magnetic clutch at the highest
durometer reading and will hold this reading against all vibrations and
jarring met with normal use. An 8-32 threaded mounting knob permits test
stand emplacement. Each Durometer Shore A comes complete with a marked,
calibrated test block made of steel (far more independent of temperature
changes than a rubber block) and carrying case.
The Durometer Shore A may be checked for calibration in 2 ways. The indenter
pin protrudes from the foot of the instrument 2.46-2.54nm (.097"-.1".)
when the dial reads zero. When the pin is inserted into the hole on the
test block and the Durometer Shore A is pressed down until the foot is resting
on the test block, the dial reading should coincide with the number stamped
on the test block.
