常用抽样检验计划

RevolutionizeInnovation常用之抽样计划介绍从MIL-STD105E到MIL-STD-1916RevolutionizeInnovation前言产业界沿用已久之MIL-STD-105E表，当可被接受的不良率由%等级演变到PPM等级时，此套抽样计划逐渐被取代。汽车业界使用之TS16949规定：计数型的抽样，其接受的等级必须是零缺点。常见以下抽样方式，取代STD-105E表：–C=0抽样计划表–MIL-STD-1916所提供之抽样计划表RevolutionizeInnovationMIL-STD-105ERevolutionizeInnovationMIL-STD-105ERevolutionizeInnovationTS16949RevolutionizeInnovationC=0抽样计划某公司RevolutionizeInnovation两者之OCCurven=200,Ac=3,Re=4n=68,Ac=0,Re=1AQL=0.650.60%,0.96600.10.20.30.40.50.60.70.80.910.00%0.50%1.00%1.50%2.00%2.50%3.00%3.50%4.00%4.50%5.00%0.60%,0.6649600.10.20.30.40.50.60.70.80.910.00%0.50%1.00%1.50%2.00%2.50%3.00%3.50%4.00%4.50%5.00%STD-105E抽样计划表C=0抽样计划表RevolutionizeInnovation两者之OCCurveAQL=0.065→n=200,Ac=0,Re=1AQL0.0650.065%0.87805831600.10.20.30.40.50.60.70.80.910.00%0.25%0.50%0.75%1.00%1.25%1.50%1.75%2.00%2.25%2.50%RevolutionizeInnovationMIL-STD-19161.SCOPE2.APPLICABLEDOCUMENTS3.DEFINITIONS4.GENERALREQUIREMENTS5.DETAILEDREQUIREMENTS6.NOTESRevolutionizeInnovationMIL-STD-19164.GENERALREQUIREMENTS4-1Acceptancebycontractor-proposedprovisions4-2Acceptancebytable4-3Dispositionofnonconformingproduct4-4Criticalcharacteristics4-5SpecialreservationsforcriticalnonconformingRevolutionizeInnovationMIL-STD-19164-1Acceptancebycontractor-proposedprovisions4-1-1GeneralRequiresthecontractortoperformsamplinginspectioninaccordancewithparagraph4.2andtheproductspecification.Whenproperproductandprocessdesignandprocesscontrolactivitiesareeffective,samplinginspectionisaredundanteffortandanunnecessarycost.Contractorsareencouragedtoconsidersubmittingalternateacceptancemethodsforoneormorecharacteristics.4-1-2RequirementsandProceduresContractors’qualitysystemsinaccordingwithMIL-Q-9858enhancedwithSPC,ANSI/ASQCQ9004arequalifiedtoapplyforalternateacceptancemethods.ThecurrentminimumvaluesofprocesscapabilityareequivalenttoaCpkof2.00forcriticalcharacteristics,1.33formajorcharacteristics,1.00forminorcharacteristics4-1-3Submissionandincorporation4-1-4WithdrawalofapprovalofalternatesRevolutionizeInnovationMIL-STD-19164-2Acceptancebytable4-2-1Preferredsamplingplansthisstandardestablishesthreesetsofmatchedsamplingplans,inspectthesamplesfromlotsbyattributesorvariablesmeasurementandforcontinuoussamplingbyattributesmeasurement.thethreesetsareindexedbysevenspecifiedverificationlevels(VL)andfivecodeletters(CL),whicharedeterminedbythelotorproductionintervalsize.4-2-2Formationandidentificationoflotsorbatches4-2-3Determinationofsamplingplana.VLasspecified.b.Typeofsampling(attributes,variables,orcontinuous)c.LotsizeCLfromtableId.Switchingprocedure4-2-4SamplingoflotsorbatchesRevolutionizeInnovationMIL-STD-1916RevolutionizeInnovationMIL-STD-1916(计数型)RevolutionizeInnovationMIL-STD-1916OCCurve00.10.20.30.40.50.60.70.80.910.00%1.00%2.00%3.00%4.00%5.00%defectratePaVL=IIICL=En=80VL=IVCL=En=192VL=VCL=Dn=384Lotsize5441~9216100ppm时,Pa仅96%2%时,Pa尚有20%RevolutionizeInnovationMIL-STD-1916(计量型)RevolutionizeInnovationMIL-STD-1916(连续型)
