BRC Issue 7 section 6.4 Calibration and Control of Measuring and Monitoring Devices spells out the need to be "checked" and when necessary "adjusted" at a predetermined frequency, based on risk assessment . This means all your measuring devices, scales, thermometers, metal detectors, instruments used to test your products ( moisture meters/water activity ect), for product safety and legality should be calibrated at some pre-determined frequency...based on our risk assessment, we chose annually. We bring in a 3rd party company to perform these certifications and then we have documentation to prove it was done. For metal detector test piece validation, we retain all purchase records from the test piece manufacturer and our 3rd party certification company verifies that our test pieces work properly.
Yes It will be brought up in an audit as it shows that you have "control" of the devices that you are using to control your processes.
Hope that helps.
Thks for above.
Not sure about the red part though.
The certified test pieces afaik are intended to validate that the MD works properly, ie is "adequately" sensitive.
(I'm not a MD expert but I guess one could dig down to the actual intensity of the MD signal which i believe some MDs now auto-do as a set-up check but signal will presumably vary with instrument. I think the more typical operational calibration/validation simply involves a reject/no-reject action.
"Calibration/validation" of the test piece itself presumably involves measuring the diameter of sphere and analysing it's composition.
PS - @Bill, Sorry, i further elaborated before seeing yr next post
