3.6.1 Quality Assurance Provisions. Quality AssuranceProvisions, used in conjunction with thi% specification, specifythose product characteristics considered to be minimum in-spection requirements for acceptability to assure conformancewith perfonsance and interchangeability requirement of theitern. The application of Quality Assurance Provisions anduse of this specification and Supplementary Quality AssuranceProvisions ”(SQAP’s) ehall not relieve the contractor fromhis responsibility to submit to the Government only productcomplying with all contract, drawing and specification require-ments.

3.6.2 Application of SQAP’S. The inspection provisionsspecified in SQAPrs and 3.6.4 should be applied at the earliestpractical point in manufacture at which it is feasible toinspect for acceptance without risk of change in the character-istic by subsequent operations. Reinspection of these character-istics on the completed product is not required providedassurance exiets that the characteristic has not been changed,degraded or damaged by subsequent manufacturing, assembly orhandling, and that adequate inspection records are maintained.In any event, the Government reserves all rights under GeneralInspection Article 5, Standard Form 32.

3.6.3 Parts and assemblies covered by SQAP’S. Where SQAP’Sare specifie?lIn the contract, the inspection provisions of theSQAPS are the minimum requirements for those parts and assembliesto which the SQAP pertains. The SQAP number ie usually the sameas the number of the product drawing to which the SQAP relates.Unless otherwise epecified on the SQAP, the drawing, or in thecontract, the contractor shall perform,”as a minimum, the ins-pections prescribed in each SQAP in accordance with the criteriaand inspection methods specified for parts and assemblies.Where a SQAP ia specified for an assembly of parts, the parts

)

of that assembly shall have been inspected for acceptabilityin accordance with the SQAP’S for those Parts (listed inPart I of the assembly SQAP). Only those parts found to beacceptable in accordance with the applicable SQAP and thisspecification shall be used in assemblies. unless otherwisespecified, Inspection Levelindividual AQLis applied in

‘LAQLts apply to each characteristic and not to a group ofcharacteristics. In addition, the contractor shall complywith this specification.

3.6.4 Parts and assemblies not covered by a SQAP orf..

fdetail speci~~catlon. The contractor shall develop and mplement,as part of his required inspection system, written detailedprocedures and criteria for inspection of all parts and assembliesnot covered by a SQAP. As a minimum, requirements for such partsand assemblies shall include:

Material identification and control, inspections to be per-formed (including inspection for workmanship, finish, missingoperations and protective coating, as well as dimensionalfeatures), defect classification, sampling criteria and proceduresin accordance with MIL-STD-105 or other appropriate Governmentsampling standards, method of inspection (gagea,measuring andtest equipment), and provisions for control and disposition ofnon-conforming items. Specified eampling criteria shall not beless stringent than Inspection Level S-4 using an AQL of 1.5 percent.

3.6.5 Inspection of parts produced and controlled byhighly repe”a”teblemanufacturing ‘techxiiques.When character-istics of the part are established and controlled by highlyaccurate and r~petitive manufacturing techniques, the firstproduction part(s) shall be examined and inspected completelyand the recorded results scrutinized very carefully to assurethat those characteristics conform to drawing, specification andcontract requirements. If the first production part(s) havebeen found acceptable to drawing, specification and contractrequirements, each of those characteristics, provided theyare unchanged by later operations, or have no more stringentinspection requirements specified in other documents, may beinspected using Inspection Level S-2 and an AQL of 1.5. Beforeimplementation of this limited inspection procedure, the con-tractor shall secure the writtsn .concurrenceof the GovernmentQuqlity Assurance Representative (QAR). The types of manu-facturing that should be considered for this procedure areas follows:

Where “Visual” is specified as the inspection methodfor protective coating, the coating shall be visuallyexamined for completeness, uniformity in appearanceand color, and for freedom from pits, corrosion,scratches, and worn or bare spots.Where “Visual” is specified as the inspection methodfor dimensional inspection, the characteristic shallbe either scaled, or compared with a specimen ofknown acceptable quality that has been establishedas an inspection standard, for conformance to therequirements of the drawing.Where “Visual” is specified as the inspection methodfor assemblies, the assembly shall be visually ex-amined for completeness, security, function andconformance to specified requirements. When possible,the functioning of the assembly shall be inspectedby manual operation.Where “Visual” is specified as the inspectionmethod for surface roughness values, a comparisonstandard conforming to ANSI B46.1 shall be used.If determination of surface roughness by a comparisonstandard is questionable, a surface-measuring instru-ment shall be used.Where “SMTE” (Standard Measuring and Test Equipment)is specified as the method of inspection, the con-tractor may use any type of industry-developed,commercially available, multi-usage equipment orspecial inspection and/or testing equipment approvedby the Government. (Previously identified as: “SME”,Standard Measuring Equipment, and “STE”, StandardTest Equipment). The contractor shall be responsiblefor utilizing SMTE which will assure full form forthe entire surface of the specified characteristic.When Government-furnished Acceptance Inspection andTest Equipment (identified as “Gages” on the SQAP),is specified as the method of inspection in thecontract or on the Data Lists, the contractor shalluse inspection equipment fabricated in accordancewith the Government drawing referenced.Where “STM” (Special Test Method) is specified asthe method of inspection, the methods and pro-cedures shall be as specified in the applicableSQAP.Alternative inspection methods and inspection equip-ment may be used by the contractor when such methods
