Rubber Test Block Kit Type A,B and O Durometer #400A
Product Details
The Test Block Kit consists of seven color-coded rubber test blocks for various Type A durometer hardness values ranging from 30 to 90. Instant identification of a specific hardness range is made easy because of the 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 D2240.
