I need some advice. I have been asked to put together a proposal for representative qualification of the equipment in our facility. Basically, we have alot of old, identical equipment that has not been qualified. We want to use specific equipment items to be “worst-case” representatives of a particular equipment grouping, test these and use their compliance to requirements (assumptions always) to cover the entire equipment group they represent. I have a clear idea in my head of what could be done (Example, IQ all 7 Grals, but OQ/PQ the 2 worst-case items based on age, performance, maintenance history, etc). However, I would like to know if there are any references that I could utilise to expand further on this.
Any assistance would be highly appreciated!!!
