Aluminum 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.
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.
Dimensions: 7/16" x 2.25" x 3/4"
