NVLAP Accredited Torque Calibration Laboratory (Lab Code, 200596-0)

Norbar CalibrationOur torque calibration laboratory makes Norbar the first torque manufacturer to be accredited by NVLAP (Lab Code, 200596-0), the accreditation department of NIST. This gives you

  • International measurement traceability that mirrors the UKAS certification produced by the Norbar factory in the UK.
  • Accredited compliance with the BS EN ISO/IEC 17025:2000 calibration quality assurance standard.
  • Explanation of the calculation of measurement uncertainties that some other manufacturers hide.


Norbar Calibration ServicesOur NVLAP (Lab Code, 200596-0) accredited torque range for transducers is from 10 oz-in to 5,000 lb-ft., and to 1,100 lb-ft for torque wrenches.

Calibration and recalibration of transducers to 5,000 lb-ft can be quickly carried out internally, on Norbar calibration equipment, with international traceability. Transducers over 5,000 lb-ft are sent to an outside partner, for NVLAP-accredited calibration.

Most recently, Norbar Torque Tools, Inc. has earned NVLAP (Lab Code, 200596-0) accreditation for our torque wrench service and recalibration lab. This means every torque wrench we service and calibrate carries a fully accredited certificate of calibration.

Torque Multipliers are also calibrated using NIST-traceable transducers and purpose built calibration fixtures.

Use Our Calculators

Norbar has devised easy-to-use online calculators that support the correct application of torque in three key areas:

  1. Unit conversion to assist international measurement definitions.
  2. Torque extension for setting correct values
  3. Torque tension to identify precise levels of torque to be applied for individual applications.
