    Regarding equipment calibration and verifications: Testing Laboratory
    1. Acceptance Criteria - My understanding of an "acceptance criteria" in this case simply means that the item in question does not fall out of the tolerances set by the test method. What happens in the case that it is not specified by the test method the the equipment was intended for? I do understand that the manufacturers generally outline the min and max range of the apparatus.. any ideas guys?

    Brayden, can you give an example of a piece of equipment youre thinking of?
    for me its a mitutoyo caliper (150mm)
    its tolerance would be +-1% accurate to get a 17025 cal cert.
    I don't know when you would set an acceptance criteria for calibration? I have to do it for interlab testing.

    It sounds to me like tolerance would cover the min and max, from what I have seen as a 10 year ukas lab manager, acceptance criteria is related to interlaboratory tests, for instance if I sent the same screws to 10 labs and told them IF any lab gets a mean of 10 results that is outside an acceptance criteria of 10% (nominal), this would raise a "discussion thread".
    IF Charanjit runs a calibration house, then perhaps he should write on the cal cert;-
    a, requester specified 1%+- of an average of three readings
    b, the equipment manufacturer for 150mm calipers from Mitutoyo is 0.02mm, an, values outside of this range will flag a non conformance?
