1.This Military Standard is approved for u by all Departments and Agencies of the Department of Defen (DoD).
2.Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of u in improving this document should be addresd to: Commander, U.S. Army Armament Rearch, Development and Engineering Center, ATTN: AMSTA-AR-EDE-S, Picatinny Arnal, NJ 07806-5000, by using the lf-addresd Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter.
3.DoD procurement practices encourage industry innovation and provide flexibility to achieve the benefits of continuous improvement.
4.There is an evolving industrial product quality philosophy that recognizes the need for quality policy changes that will provide defen contractors with opportunities and incentives toward improv
ement of product quality and cooperative relationships between the contractor and the Government.
5.Process controls and statistical control methods are the preferable means of preventing nonconformances, controlling quality, and generating information for improvement. An effective process control system may also be ud to provide information to asss the quality of deliverables submitted for acceptance. Suppliers are encouraged to u process control and statistical control procedures for their internal control and to submit effective process control procedures in lieu of prescribed sampling requirements to the Government for approval.
6.Sampling inspection by itlf is an inefficient industrial practice for demonstrating conformance to the requirements of a contract and its technical data package. The application of sampling plans for acceptance involves both consumer and producer risks; and incread sampling is one way of reducing the risks, but it also increas costs. Suppliers can reduce risks by employing efficient process with appropriate process controls. To the extent that such practices are employed and are effective, risk is controlled and, conquently, inspection and testing can be reduced.
7.The following points provide the basis for this standard:
a.Contractors are required to submit deliverables that conform to requirements and to
generate and maintain sufficient evidence of conformance.
b.Contractors are responsible for establishing their own manufacturing and process
controls to produce results in accordance with requirements.
c.Contractors are expected to u recognized prevention practices such as process
controls and statistical techniques.
8.This standard also provides a t of sampling plans and procedures for planning and conducting inspections to asss quality and conformance to contract requirements. This standard complies with the DoD policy of eliminating acceptable quality levels (AQL's) and associated practices within specifications.
