Do X-Ray Test Pieces Need to be Certified?

Can anyone clarify if test pieces used for daily checks of the X-Ray need to be certified?

If so what standard does it state that is the case, or is it just considered best practice?

Thanks 

Which standard are you working with? As I guess the regulation can vary between them.

We have test pieces that the manufacturer supplied to us with the machine. They are controlled at the same time as our annual calibration tests are done.

Don't think they are "certified" and none of the auditors that have been here have had any remarks on them.

I would pose the question to your metal detector manufacturer - what have they seen/heard within the food industry from other customers, in terms of complying with certification/audit requirements?

In my experience, documentation from the manufacturer that the pieces were verified to be correct (size, material, etc.) is sufficient, especially if the test material is enclosed in some way (inside of a card, which is common for Mettler-Toledo and others; or inside of a rod or sphere, which is also common)...if it's still enclosed as it was when it was new, there's really no way to have "adulterated" or modified it, so original documentation from the manufacturer should suffice...at least, it has in our past audits.

If you find out anything different from your metal detector manufacturer, would you kindly share what you learn with the rest of us?  I'm curious as to what they say!

Thanks for the replies....at a previous company I worked for our documentation stated that test pieces must be certified against:

"AFBMA (Anti Friction Bearing Manufacturers Association – USA standard), Din Metric (German) or ISO (international)"

I was just unsure whether there was a requirement for this to be the case, or if it was just the internal company policy? The company I currently work for has no real Foreign Matter Procedures which I am developing. The current company is ISO9001 certified and is deciding whether to move forward with either  BRC or FSSC22000.

Our test pieces are supplied by JIMA and are encased in plastic and are in good condition. I don't believe the engineers have any of the original documentation for them.
