Test Block Kits

"A" and "D" Scales

Durometer Hardness Standards

This kit will prove to be invaluable in helping to maintain durometer read-out accuracy for scientific, manufacturing, and research and development use. As a reference check, it will indicate if a durometer is operating within tolerances.

"A" scale consists of 7 color-coded rubber test blocks of various Type A durometer hardness values ranging from 30 durometer to 90 durometer, and are housed in a convenient, rigid, custom-fit protective box. "D" scale consists of 3 test blocks ranging from 20 to 80 durometer.

Instant identification of a particular hardness range is made fast and easy because of our advanced color identification.


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 D 2240.

The material (rubber) from which the test blocks are made is fairly stable, however, it is strongly recommended that calibration of these test blocks be verified annually.


Guarantee

Durometers and accessories are guaranteed for a period of one year against defective workmanship and/ or material. The guarantee does not apply to products that are mishandled, misused, etched, stamped or otherwise marked or damaged. We reserve the right to change the design without notice
