    If we screen and then qualify a part to the MIL-STD 883, do we have to qual every subsequent lot if nothing has changed in it's design or 883 std process flow?

    Look in your MIL-STD 883 Specifications book.

    The current standard is MIL-STD-883G, dated February 2006.
    It is available in PDF form here:
    http://www.dscc.dla.mil/Programs/MilSpec/listDocs.asp?BasicDoc=MIL-STD-883

    If you are not in compliance with any portion of the specification, you cannot claim that your components are within the specification.

    Without referring to the current document, I can tell you that you must test every lot to the specification in order to be within compliance guidelines.

    They are strict for good reasons.

    Every lot is screened to spec. My question was just on qualification - the added steps of taking a sample of parts and running them through group a,b,c,d. Must that be done every lot? What if you're lot is small? For example, HTOL is min 45 pcs, sometimes our demand from customers are far less than that, and it's build to order. While everything is screened according to 883 screening procedure, do we have to do a qual every time (which amounts to building and destroying more parts than customers order?).
