Where did the question come from? Can mistake-proofing be bypassed under what circumstances? What's a "red part test"? What does ">FREQUENCY" mean? :confused:

Do you mean running a red (defective) part to check the test of a test machine?

the question came from my QSA audit report.

they(coustomer) want us to make a defective part and put it in the fixture and check weather non confirming part can be made and define the frequency for the same .

so i needed a format sample?:)

This is a standard test which is usually done at setup and change of shift.
Just add the check to your normal setup sheet.
Red part past test Yes/NO
You should also have a green part to check that this works as well

If Howard's assumption is correct - it is also known as a "rabbit test" and follows Howard's red and green samples being run through to verify the device is working properly.

Not really. It depends upon the specific test apparatus. As Howard pointed out, this is a simple matter of having a known good part and a known defective part and running both through the test apparatus to ensure the test apparatus if functioning correctly. Quite common and in general a good idea.
