Hello, As in title I have a question about material tests for PPAP. Maybe it will be obvious but please give me some answer because I'm stack with this I recieved test results form accredited laboratory and I prepared my report for customer but I dont relly know with what i should compare this results. for example result =5 and I am really happy for it... but is it OK or NOK? I should compare it with supplier statement or maybe (customer have GM requirements) customer have his own tolerance and if yes where can I find it? I looked at many places but still don't have clear answer. I am talking about plastics parts.
