This recommended practice’s series of documents establishes the general requirements
applicable to any of the methods of statistical product acceptance to reduce inspection costs
while still assuring acceptable quality. There is no single specific plan that can be considered
best suited for all applications or processes. This ARP9013 document contains the basic
requirements needed to implement the statistical methods described in ARP9013/1 through
ARP9013/4 series to control outgoing quality. All applicable requirements of this ARP9013
document shall be met when using one or more of the ARP9013/1 through ARP9013/4
recommended practices.
This document does not apply to statistical methods that are separate from product acceptance.
Many companies use excellent statistical methods solely to monitor and improve their product
quality, and those methods are not subject to the requirements of this document. This
document applies only to those statistical methods used for product acceptance.
The requirements are contained in the main body of this recommended practice. This
recommended practice also includes several appendices, which are offered for guidance or
recommendation purposes only. Each appendix herein contains only nonmandatory
suggestions, examples, or further discussion on specific topics that the authorship believes will
aid the successful implementation of this recommended practice for the user organization.
Products which may be eligible for the methods defined in this recommended practice’s series
include but are not limited to end items; cast, forged, wrought, machined, fabricated, plastic,
molded, powdered metal, or stamped components and raw material; electronic, electrical, and
mechanical components; lots subjected to receiving inspection, in-process inspection, and final
inspection; supplies in storage; and services, any of which may be produced in batches, large or
small lots, continuous processes, or single-piece flow manufacturing processes.
1.1 Purpose:
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.
1.2 Field of Application:
This recommended practice is applicable when invoked in a purchasing contract or
specification, other contractual document, customer agreement, or adopted by the
organization. The appropriate slash-numbered recommended practice(s) in this series
applied by the organization may or may not be specified by the purchaser’s contract, but
does form a part of the ARP9013 flowdown requirement.
If desired to sample a series of lots without using ARP9013/1, ARP9013/2, or ARP9013/3,
the requirements of ARP9013/4 shall be used.strRefField
