Measuring Torque

Uniform realization of torque measurement is needed in the United States

From the tightening of nuts on automobiles and airplanes to the connections on wind generators and other structures, the accurate measurement of torque may be essential for safety and the financial future of many companies in North America. Unfortunately, unlike other countries such as Germany, Mexico, or the United Kingdom (UK), the United States has lacked a traceable torque standard against which companies can verify their torque instruments. Companies wishing to verify torque measurements must send capital and equipment to foreign countries for calibration. Companies not following this practice are making torque measurements based on an assumed length and force, which has proven to be inaccurate. These imprecise measurements may be caused by the calibrated beam deflecting and the introduction of side loads, both of which are not accounted for when the beam and masses are calibrated.

Torque Not Traceable through NIST

Is Henry saying that NIST is not providing traceable standards for torque calibrations?

In reply to Torque Not Traceable through NIST by jackdearing

NIST does not provide Torque Calibration Services

N.I.S.T traceability through length and force does not mean that the lab performing the torque calibration is doing it accurately.  

NIST cannot close the loop for verification of a torque system.  To do this you have to use another NMI such as PTB,CENAM or now that we(Morehouse) have the equipment from a NMI (NPL)  we can verify a torque transducer that a company can use to verify their torque equipment is accurate.
