31、various manufactur-ers and processors. Historic limitations of a product based upondimensions (thickness, width, and length) do not take intoaccount current production and processing capabilities. Toqualify any product to a particular product specification re-quires all appropriate and necessary tes

32、ts be performed and thatthe results meet the limits prescribed in that product specifi-cation. If the necessary tests required by a product specificationcannot be conducted, the product cannot be qualified to thatspecification. This general requirement standard contains per-mitted variations for the

33、 commonly available sizes. Permittedvariations for other sizes are subject to agreement between thecustomer and the manufacturer or processor, whichever isapplicable.3.1.1.4 Slabs, sheet bars, and skelp, though frequentlyfalling in the foregoing size ranges, are not classed as plates.3.1.1.5 Coils a

34、re excluded from qualification to the appli-cable product specification until they are decoiled, leveled orstraightened, formed (if applicable), cut to length, and, ifrequired, properly tested by the processor in accordance withASTM specification requirements (see Sections 9, 10, 11, 12,13, 14, 15,
