Could you please tell me if i can treat the gage certificate as a calibration evidence when i first use the gage?or I need to calibrate the gage before I first use it?Thanks for kindlly help! :thanks:

Was the lab that calibrated the instrument accredited to do so? If yes, then you don't really need to, however, it doesn't hurt if you have the time and the resources. :)

One more thing - is the certificate traceable to the individual gage and to national or international standards? If not, I wouldn't accept it.

Also, do you have the measurement uncertainty?

I agree with the advice received on this post.

I am coming from an QS-9000 percepective where the mfg. "certification" wouldn't pass in my audits. But, as QS-9000 is obsolete, from an ISO-9001:2000 perspective, I agree with the other comments, as long as this "certification" from the OEM is traceable to a National Standards or say 17025 I would accept it.

Also, note that you should determine when somethingsneeds calibrating as to how "critical" this tool is to your process. Something like a CMM should be "Calibrated" in my opinion. Most calipers, micrometers, etc. that you use everyday for any critical measurments should also be calibrated in my opinion. Mics, calipers, etc. that are used for reference only, accept the "certification" cert, stick a reference only sticker on the tool and use it just for reference.
