Test Blocks


PTC® recommends aluminum verification blocks be used as a field check of the durometer. They provide an indication if the durometer is mechanically sound prior to use. The block is a combination depth gauge and spring force gauge designed to provide consistent results in a wider temperature range than rubber or plastic blocks. The value of each block is measured using a certified durometer. ASTM D2240 states that test blocks are not to be used as calibration standards. The calibration procedure for a durometer includes mechanical, dimensional and force curve measurements as stated in Section 7. For NIST traceable durometer calibration please contact PTC Metrology™.

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.
