9、 and procedures, permit-ted variations in dimensions, and mass, quality and repair ofdefects, marking, loading, and ordering information.3.2 In addition to the basic requirements of thisspecification, certain supplementary requirements are availablewhen additional control, testing, or examination is
10、 required tomeet end use requirements. The purchaser is referred to thelisted supplementary requirements in this specification and tothe detailed requirements in Specification A20/A20M.3.3 Coils are excluded from qualification to this specifica-tion until they are processed into finished plates. Pla
