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.
