    Good day QFO community;
    Modern manufacturing equipment is often complex digitally controlled machinery. We have all seen situations where even a brief power outage can cause significant challenges with regard to restart-verification-clearing/containing "in process" product from machinery, etc..etc...

    The auditable clause in the standard (8.5.1.4) makes no reference to the amount of time required to be called a "shutdown" .
    However, section 3.1 "Terms and abbreviations..." attempts (poorly) to quantify exactly what can be considered as a "shutdown" as follows...

    "Condition where manufacturing processes are idle; time span may be a few hours to a few months"


    It is indeed an extremely "loose" explanation, and I for one believe the standard/we would all be better off if the IATF team had NOT attempted to define it. Seems to me "planned or unplanned shutdown" is pretty self explanatory.

    So. As ridiculous of a question as this seems to be, what say all of you with regard to what is considered a planned or unplanned shutdown.

    Thoughts?

    Be well.

    Unplanned, to me is when an incident occurs such as machinery breakage or a process or product characteristic not being met. Planned would be end of shift, tooling change over, maintenance. As you say, pretty explanatory.
