At what frequency should the MSA be repeated? Our QS 9000 auditor (UL) has ask this question, & we do not have a stated frequency for repeating MSA. Can anyone provide guidelines or suggestions? IP: Logged |

Typically once a year or any time a change is made which will affect the gage or whatever. IP: Logged |

Once a year sound too gross to me. Shouldn't you conduct R&R after every calibration? Help ... IP: Logged |

Atul, We have over 2,000 variable gauges on site, to do GR&R studies on all of them once a year is an impossible task. We handle the problem by working to an 'audit schedule' where each TYPE of gauge is reviewed at least once per year. The gauge to be reviewed for the audit period is selected at random. We also carry out two GR&R studies as part of our 6 Sigma projects. These are over and above the one carried out as per the schedule. Geoff IP: Logged |

quote:You really have to look at the over all use of the gage, its stability and such. For example - If you have a fairly stable gage and your cal cycle is every 6 months I'm not sure an R&R after each calibration will buy you anything. The R&R should not change after a calibration. If you wanted some useful info, you might do an R&R just after a calibration and then another one just prior to the next calibration. Are you currently doing an R&R after every calibration?

Geoff , Marc Yes, i would like to agree with what you are saying. Actually, i'd much prefer to calibrate an instrument based on stability study. And since calibraton involves some adjustments to the instrument, i thought r&r is in order. I have come across customers who insist on submitting r&r results with each consignment. So, the original question remains: Are there any definitive guidelines? At least any thumb rules? IP: Logged |
