Hi all,
OK,
So I understand that items rejected by metal detection and x-ray are to be investigated. The purpose of this is to understand exactly what made the rejection take place. I am led to believe the need to know the true nature of the physical contaminate that caused the rejection is toward the value of it's possible relation as a precursor to other problems and in general how you got a physical contaminate in your product.
But does this investigation have to begin and be completed prior to shipment? Devil's advocate, if you find a piece of light blue plastic in a product, do you have to open and close the investigation, thereby identifying where this random light blue piece of plastic came from before final release? It feels improbable that you would have to complete the investigation prior to final release because the investigation could take time and be to disruptive to the industry.
AND,
What if instead of x-ray, the waste stream to be analyzed was a dud kickout? The dud kick out scenario is different in my opinion because the x-ray investigation one could argue may have implications in the rest of the lot that went undetected as x-ray does not always catch everything. I don't feel that the dud kickout investigation results present the same value as they do not have broader implications to the lot that may have went undetected.
So I don't believe either investigation should prevent the finished good that successfully passed all checks and testing from being released.
Thoughts please...
