made possible by our extensive laboratory solely devoted to precision torque transducer calibration. It contains 9 accredited* calibration stands including the 4,000,000 lbf-in stand shown in the video. That stand is one of three2 worldwide accredited for calibrations above 1,000,000 lbf‑in and has the lowest uncertainty of any. Available stands are listed below.

Calibrations include a NVLAP approved certificate of traceability to the NIST and verifying our laboratory (NVLAP Lab Code 200487-0) fulfills the management system, technical competence and quality requirements of ISO/IEC 17025:2005. Visit our website at www.himmelstein.com or use the “Laboratory Accreditation” link at www.nist.gov to download our NVLAP Certificate and Accreditation. NVLAP is an arm of the NIST (National Institute of Science and Technology).
- Does not apply where fixture modifications are needed to accommodate unusual configurations.
- Two others are in use; one at PTB (Physikalisch Technische Bundesanstalt, Germany) and one at LNE (Laboratoire national de metrologie et d’essais, France). Both are Government owned.
- Expanded uncertainty using a coverage factor, k=2, at an approximate 95% confidence level.
- Two of these stands are available; all others are a quantity of one.
