This standard is primarily intended to apply to new parts and products, but can also be applied to parts currently in production. The standard shall be applicable to all production processes, that influence the variation of KCs, as well as maintenance processes in which KCs are identified. It applies to assemblies and all levels of parts within an assembly, down to the basic materials including castings and forgings, and to organizations that are responsible for producing the design characteristics of the product. It does not apply to lab-scale, pilot, or pre-production processes. However, particular management of some KCs might be required using other methods than those described in the standard, during these phases of a program, when required by the customer or deemed appropriate by the organization (e.g., Engineering department requirement).

This standard is primarily intended to apply to new parts and products intended to be produced in an on-going production phase, but can also be applied to parts currently in production (e.g., manufacturing, maintenance). The standard is applicable to all production processes that influence the variation of KCs, as well as maintenance and service processes in which KCs are identified. It applies to organizations for assemblies and all levels of parts within an assembly, down to the basic materials including castings and forgings, and to organizations that are responsible for producing the design characteristics of the product. The variation control process begins with product definition, typically stated in the design documentation (e.g., digital model, engineering drawing, specification) which identifies KCs, and leads to a variation management process for those KCs. This process may also be used for producer-identified KCs (e.g., process KCs, additional/substitute product KCs).

This document contains the minimum requirements for supplier Inspection and Test Quality System. It is emphasized that the quality system requirements specified in this standard are complementary (not alternative) to the contractual and applicable law and regulatory requirements.

This SAE Aerospace Recommended Practice (ARP) establishes the general requirements when implementing any of the statistical product acceptance methods as defined in ARP9013/1, ARP9013/2, ARP9013/3, and ARP9013/4. This recommended practice also establishes the minimum content required to be covered in an organization’s documented procedures that govern their application of statistical product acceptance methods. These general requirements and documented procedures apply the requirements of AS9100 plus requirements for retrievability, safety/critical characteristics, quality parameters, and that these parameters protect the customer. This recommended practice is to be used in conjunction with the variety of sampling strategies, statistical techniques, and process control methods of the ARP9013/1 through ARP9013/4 recommended practices as chosen by the organization.

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 "Zero Acceptance Number Sampling Plans " by Nicholas L. Squeglia.

The purpose of ARP9013/4 is to ensure conformance for each product characteristic being verified under these methods. ARP9013/4 provides the requirements for continuous sampling, skip-lot sampling, and for statistical methods for product acceptance that do not derive from industry standard tables.

The purpose of this SAE Aerospace Recommended Practice (ARP) is to ensure conformance for each product characteristic being verified in a lot, without maintaining information from previous lots. ARP9013/1 specifies a product acceptance system for isolated lots. For example, isolated lot sampling avoids keeping track of the normal, tightened, and reduced levels of sampling formerly used in MIL-STD-105 and currently used in ANSI/ASQC Z1.4. Because those switching rules provided significant long-term protection for product quality, these isolated lot tables replace that protection in other ways.

ARP9013/3 recommended practice specifies a product acceptance system using process control methods. Its purpose is to assure conformance for specified characteristics. Use of process control techniques for product acceptance requires maintaining process stability and capability. A stable and capable process is the best assurance of conforming hardware for the customer. There can be lower inspection costs associated with a process control acceptance approach.
