 Application Form for Tracker Sheet use

This is the form to complete if your centre does not use a thread gauge for checking diving cylinders or valves on a frequent basis.  IDEST allows centres to use a Tracker Sheet for each gauge that will not exceed 250 uses within a 3 year period.  Once a gauge has been used 250 times or three years have elapsed, whichever occurs first, then the gauge must be re-calibrated.  These gauges do not then need to be recalibrated every year.
