Tradelab performs the calibration of hydraulic, electric and pneumatic screwdrivers of static torque with ENAC (ILAC) accreditation.
The calibration carried out by Tradelab consists in applying, with the screwdriver to be calibrated, pre-established torque values on a bench of standard torque measurement.
The correction value is determined in each calibrated torque, normally from 10% to 100% of the f.s., as well as its associated expanded uncertainty.
In the case that the applied torque values were referenced to a pressure value, indicated by the hydraulic pump monometer, determining the output torque according to the input pressure.
