Instructions for Calibration of Inspection and Test Equipment

1. Hydro-pressure, gas pressure gauges and torque wrenches are calibrated annually or when suspected to be in error with a standard deadweight tester or a calibrated Master gauge. The Master gauge is calibrated annually. Pressure gauges are believed to be in error if the pressure indicator reads different than the gauge being used.
2. Dial indicators are calibrated monthly, traceable to National Institute of Standards & Technology.
   The calibration test bars are in 25mm increments. A 125mm micrometer is used to check the I.D.
   Overall appearance and cleanliness is checked.
3. Micrometers are calibrated semi-annually with the same calibration test bars as the dial indicators, which are traceable to National Institute of Standards & Technology.
