PTC® recommends 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. | |||||||||||||||||||||||||||||||||
PTC Metrology is Accredited by A2LA for durometer calibration to ISO/IEC 17025, ANSI/NCSL Z540-1. NIST Traceable certification is available for all durometer types covered by current ASTM D2440, ASTM F1957, ISO 868, ISO 7619, or DIN 53505 standards. The Calibration Report will include both "as received" and "as left" data. Complete Durometer calibration includes: indenter geometry and extension, indicator linearity from 0 to 100 and mainspring force. |
