Dear All
In our factories we metal detect all finished products leaving the
factories, in some cases we metal detect incoming raw material. We
verify that the metal detectors are functioning on an hourly basis using
test wands of set sizes obtained from the suppliers of our Metal
Detectors. These test wands are plastic strips with a metal ball of
predetermined sizes set in Perspex at one end.
At a recent regulatory HACCP audit we were asked about calibration of
these test wands, how often we do it and they wanted calibration
certificates. I have never been asked this by any other auditor and
have never heard of this being done, so my question is: Does anyone
have any information regarding this matter that would help clarify the
situation for me? If anybody has had their test wands calibrated, how
did you go about it?
