PTC Metrology™ Durometer Calibration Certification to ISO/IEC 17025 ANSI/NCSL Z540-1


PTC® manufactures, repairs and calibrates durometers to ISO 17025. Including Shore, Rex, Mitutoyo, and others.

A written calibration report for any durometer covered by current ASTM D2440 or ASTM F1957 specifications is available from PTC Metrology™ Certification provides "as received" and "as left" data. Calibration points for force curve and gage linearity are every 10 points over the scale (0-100) of the durometer.

All Calibration Standards are traceable to the National Institute of Standards and Technology (NIST). Durometer calibration services and reports are provided by PTC Metrology™ and will meet your ISO, ANSI, MIL, DoD, EuroNorm and other international standards including DIN 53505, ISO 868 and ISO 7619.

PTC® durometers type A, B, C, D, DO, E, M, O, OO, OOO and OOO-S are calibrated in accordance with ASTM D2240 section 7 which includes the following measurements:
  1. Indenter Geometry
  2. Indenter Extension
  3. Gage Linearity
  4. Force Curve Measurement
A2LA has MRAs (mutual recognition agreements) with NVLAP, NIST, EA, ILAC, IAAC, and NACLA (see http://www.a2la.org/recognition/cooplabs.cfm ) for details.
