Designation:E291012An American National StandardStandard Guide forPreferred Methods for Acceptance of Product1This standard is issued under the fixed designation E2910;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This guide establishes lot or batch and continuoussampling plans using MIL-STD-1916 as a basis.It representsan alternative sampling approach to attributes sampling(MIL-STD-105E,same as E2234),variables sampling(MIL-STD-414,E2762),and continuous sampling(MIL-STD-1235B,E2819).1.2 This guide provides the sampling plans of MIL-STD-1916 in ASTM format for use by ASTM committees andothers.It recognizes the continuing usage of MIL-STD-1916 inindustries supported by ASTM.Most of the original text inMIL-STD-1916 is preserved in Sections 4-6 of this guide.Theoriginal wording of“Government”in MIL-STD-1916 has beenchanged to“consumer”,and“contractor”has been changed to“producer”to make this standard more generic.1.3 PurposeTo encourage producers supplying goods andservices to its consumers to submit efficient and effectiveprocess control(prevention)procedures in place of prescribedsampling requirements.The goal is to support the movementaway from an AQL-based inspection(detection)strategy toimplementation of an effective prevention-based strategy in-cluding a comprehensive quality system,continuous improve-ment and a partnership with the consumer.The underlyingtheme is a partnership between consumer and the producer,with the requisite competence of both parties,and a clearmutual benefit from processes capable of consistently highquality products and services.The objective is to create anatmosphere where every noncompliance is an opportunity forcorrective action and improvement rather than one whereacceptable quality levels are the contractually sufficient goals.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2E456 Terminology Relating to Quality and StatisticsE2234 Practice for Sampling a Stream of Product by Attri-butes Indexed by AQLE2762 Practice for Sampling a Stream of Product by Vari-ables Indexed by AQLE2819 Practice for Single-and Multi-Level ContinuousSampling of a Stream of Product byAttributes Indexed byAQL2.2 Other Standards:3MIL-STD-105E Sampling Procedures and Tables for In-spection by AttributesMIL-STD-1235B Single-and Multi-Level Continuous Sam-pling for AttributesMIL-STD-1916 DoD Preferred Methods for Acceptance ofProductMIL-STD-414 Sampling Procedures and Tables for Inspec-tion by Variables for Percent Defective3.Terminology3.1 DefinitionsThe terminology defined in TerminologyE456 applies to this guide except as modified below.3.1.1 critical defect,na defect that judgment and experi-ence indicate would result in hazardous or unsafe conditionsfor individuals using,maintaining,or depending upon theproduct,or a defect that judgment and experience indicate islikely to prevent performance of the function of a major enditem.E22343.1.2 inspection,nthe process of measuring,examining,testing,or otherwise comparing the unit of product with therequirements.E22343.1.3 major defect,na defect,other than critical,that islikely to result in failure,or to reduce materially the usabilityof the unit of product for its intended purpose.E22341This guide is under the jurisdiction of ASTM Committee E11 on Quality andStatistics and is the direct responsibility of Subcommittee E11.30 on StatisticalQuality Control.Current edition approved Dec.1,2012.Published February 2013.DOI:10.1520/E2910-12.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from Standardization Documents Order Desk,DODSSP,Bldg.4,SectionD,700RobbinsAve.,Philadelphia,PA19111-5098,http:/dodssp.daps.dla.mil.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.1.4 minor defect,na defect that is not likely to reducematerially the usability of the unit of product for its intendedpurpose,or is a departure from established standards havinglittle bearing on the effective use or operation of the unit.E22343.1.5 non-conforming item,nan item containing at leastone non-conformity.E22343.1.6 production interval,na finite period of production,N items in length.E28193.1.6.1 DiscussionIn this guide,the production interval isa period of production under continuous sampling assumed toconsist of e
