My company is preparing to upgrade our ISO system to QS-9000. There is difference of opinion as to whether process gauges (i.e. pressure, temperature, rpm, etc.) are to be included in the gauge control system (calibration / verification). We are a raw material compounder and all product is accepted or rejected in a laboratory. Has anyone experienced problems with registration to QS-9000 where process gauges were not in the gauge control system?
