Designation:B60288(Reapproved 2016)Standard Test Method forAttribute Sampling of Metallic and Inorganic Coatings1This standard is issued under the fixed designation B602;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 test method gives sampling plans that are intendedfor use in the inspection of metallic and inorganic coatings forconformance to ASTM standard specifications.1.2 The plans in this test method,except as noted,have beenselected from some of the single sampling plans of MIL-STD-105D.The specific plans selected are identified in Tables 1-3 ofthis test method.The plan of Table 4,which is used fordestructive testing,is not from the Military Standard.Thisstandard does not contain the Military Standards requirementfor tightened inspection when the quality history of a supplieris unsatisfactory.1.3 The plans are based on inspection by attributes,that is,an article of product is inspected and is classified as eitherconforming to a requirement placed on it,or as nonconforming.Sampling plans based on inspection by variables are given inTest Method B762.Variables plans are applicable when a testyields a numerical value for a characteristic,when the speci-fication imposes a numerical limit on the characteristic,andwhen certain statistical criteria are met.These are explained inTest Method B762.1.4 The plans in this test method are intended to begenerally suitable.There may be instances in which tighter orlooser plans or ones that are more discriminating are desired.Additional plans that may serve these needs are given in GuideB697.Also,Guide B697 describes the nature of attributesampling plans and the several factors that must be consideredin the selection of a sampling plan.More information and aneven greater selection of plans are given in MIL-STD-105D,MIL-STD-414,ANSI/ASQC Z1.9-1979,Refs(1-7)2,and inGuide B697.1.5 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:3B697 Guide for Selection of Sampling Plans for Inspectionof Electrodeposited Metallic and Inorganic CoatingsB762 Test Method of Variables Sampling of Metallic andInorganic Coatings2.2 ANSI Standard:4ANSI/ASQC Z1.9-1979 Sampling Procedures and Tablesfor Inspection by Variables for Percent Non-Conformance2.3 Military Standards:5MIL-STD-105D Sampling Procedures and Tables for In-spection by AttributesMIL-STD-414 Sampling Procedures and Tables for Inspec-tion by Variables for Percent Defective3.Terminology3.1 Definitions:3.1.1 destructive testtest that destroys the tested article ormakes it nonconforming to a requirement.3.1.2 inspection lotcollection of articles of the same kindthat is submitted to inspection for acceptance or rejection as agroup.3.1.3 nondestructive testtest that neither destroys thetested article nor makes it nonconforming to a requirement.3.1.4 samplearticles randomly selected from an inspec-tion lot whose quality is used to decide whether or not theinspection lot is of acceptable quality.4.Significance and Use4.1 Sampling inspection permits the estimation of the over-all quality of a group of product articles through the inspectionof a relatively small number of product items drawn from thegroup.1This test method is under the jurisdiction ofASTM Committee B08 on Metallicand Inorganic Coatingsand is the direct responsibility of Subcommittee B08.10 onTest Methods.Current edition approved Nov.1,2016.Published November 2016.Originallyapproved in 1975.Last previous edition approved in 2010 as B602 88(2010).DOI:10.1520/B0602-88R16.2The boldface numbers in parentheses refer to the list of references at the end ofthis standard.3For 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.4Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.5Available from Standardization Documents Order Desk,DODSSP,Bldg.4,Section D,700 Robbins Ave.,Philadelphia,PA 19111-5098.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 4.2 The selection of a sampling plan provides purchasersand sellers a means of identifying the minimum quality levelsthat are considered to be satisfactory.4.3 Because sampling plans will only yield estimates of thequality of a product,the results of the inspection are subject toerror.Through the use of sampling plans
