Product Code:SAE ARP9013/2
Title:Statistical Product Acceptance Requirements Using Attribute Or Variable Lot Acceptance Sampling Plans
Issuing Committee:G-14 Americas Aerospace Quality Standards Committee (Aaqsc)
Scope:The purpose of ARP9013/2 is to ensure conformance for each product characteristic being verified in each lot in the series. ARP9013/2 document specifies a product acceptance system using either attribute or variable lot acceptance methods documented in ANSI/ASQC Z1.4, ANSI/ASQC Z1.9, and 驴Zero Acceptance Number Sampling Plans驴 by Nicholas L. Squeglia.
