The company I intern for has a NADCAP (National Aerospace and Defense Contractors Accreditation Program) certification for some of their tanks. This certification is an industry-managed approach to conformity assessment of special processes that brings together technical experts from prime contractors, suppliers and establish requirements for approval of suppliers using standardized approach. The Performance Review Institute (PRI) administers the NADCAP program. PRI will schedule an audit and assign an approved auditor who will conduct the audit against an industry agreed standard using an industry agreed checklist. To everyone that answered yes it is stressful, yes it is stressful. When the government comes into the building its always a serious tone within the lab. I found myself not worrying so much because I was in charge of keeping the lab clean and since I was an intern theirs not much they can I ask me.
