29、estUnless otherwise specified by thepurchaser, adhesives that have not passed the qualificationtests, or that have previously passed the tests but havesubsequently been modified in any manner, must be testedagainst this specification and shown to meet its requirements.7.1.1.1 Instruction SheetA date

30、d, coded, and titled in-struction sheet that outlines instruction for use of the adhesiveon bonding metal facings to foam core and metal componentsshall be supplied by the manufacturer. These instructions shallbe forwarded with the test report when requesting qualification.In addition, a copy of the

31、 instruction sheet shall accompanyeach shipment of the adhesive.7.1.2 Reevaluation ProcedureIn the event that two ormore test results should fall below the minimum specified forany of the qualification tests, the submitted product shall beconsidered to have failed qualification testing. In this case

32、, thelot along with two additional lots may be retested for that test.If all of these pass, the product will be considered as beingqualified.7.2 Quality Conformance Inspection The number of testspecimens for conformance testing shall be five.
