I have used a calibration company in Hove to get my Mitutoyo electronic guages and verniers calibrated , and he did check Petes generic half inch torque wrench similar to Clarkes or Halfords type and it was about 2% out which is within average tolerance ,
In the offshore work most systems Torque wrenches are calibrated every 3 years most fall within a 2-3% tolerance ,, they are mostly 3/4 size and 1/2'' size and are Norbar or Britool or expensive electronic ones .These are the critical ones for safety laoding and weight tests and readings are recorded ..
The rest are mostly smaller Red TENG ones and dont get called for calibration ,, most seem to go ''missing'' and are regularly replaced ,,Thats where my 3 Tengs came from all brand new when I went to a system that had 4 of each type 1/4 , 3/8 1/2 . most never get used by the teams ,, its ususally me who insists on using small torque wrenches ,, when rebulding pumps or motors or manipulators so the seals dont get over torqued ,
