National Aerospace and Defense Contractors Accreditation Program (Nadcap)
What is Nadcap?
航空宇宙・防衛部品製造において、世界的に統一した基準による特殊工程管理を実施することで、全てのサプライヤーの品質を維持することを目的とした認証プログラム。Nadcap は、National Aerospace and Defense Contractors Accreditation Programの略称。
「製造およびサービス提供の過程で生じるアウトプットが、それ以降の審査及び測定で検証することが不可能な場合（製品が使用されサービスが提供された後でしか不具合が顕在化しない場合）」の作業工程を指し、具体的には機械加工、熱処理、表面処理、ショットピーニング、非破壊検査などが該当する。
