control of measurement devices
(OP)
Pertaining to control of measurement devices. I just started work for a new company which is ISO 9001 certified and they are trying to get away without calibrating measuring instruments by labeling everything but a few micrometers and calipers "For Reference Only". I can't find a clear statement in the 9001 standard. I thought all measuring devices that determined an object meets customer requirements must be calibrated and traceable to NIST.
Can anyone point me in the right direction if this statement exist, where can I find it in writing?
Thanks,

I did not specifically see NIST but what does your customer say?

To decrease calibration costs you can't simply mark everything as for reference only.. But you can reduce the number of tools used or decrease the frequency of calibration or move calibration to be done internal with master blocks,etc..
RE: control of measurement devices
......Where necessary to ensure valid results, measuring equipment shall
a) be calibrated or verified, or both, at specified intervals, or prior to use, against measurement standards traceable to international or national measurement standards; where no such standards exist, the basis used for calibration or verification shall be recorded (see 4.2.4);
c) have identification in order to determine its calibration status .....
Records of the results of calibration and verification shall be maintained (see 4.2.4).

Thanks Again!

If it on your control plan it needs to be calibrated is my simple answer!
