Recalibration should be 5000 cycles or every 12 months. However, the standard recognises that many businesses will have their own procedures for the control of test devices and, as a torque wrench can be considered a test device, a company’s own procedures must take precedence over the default 5000 cycles/12 months.
The reason that there is really no simple answer to the recalibration is that circumstances of use will vary widely and this will have a direct bearing on how long the torque wrench is likely to stay in calibration. Factors such as the frequency of use, setting of the wrench as a percentage of full scale, general care taken in use and storage, ambient conditions in use and storage will all have their effect.
