Rubber Test Block Kits
While these test blocks are a
convenient form of comparative verification, they are not intended to be
used for the purpose of durometer calibration. Rather, they are a form
of "quick reference" to the operational status of the durometer being
used. A large variation would indicate the need for recalibration of the
durometer being utilized. This should be done in accordance with the
methods indicated in ASTM D2240.
