37、in. 6 mm or over in thickness.(2) Over 48 in. 1200 mm in width and 0.180 in. 4.5 mm or over in thickness.3.1.1.2 When Ordered to Weight Mass:(1) Over 8 in. 200 mm in width and 9.392 lb/ft2 47.10 kg/m2 or heavier.(2) Over 48 in. 1200 mm in width and 7.350 lb/ft2 35.32 kg/m2 or heavier.3.1.1.3 Discuss
38、ionSteel products are available in various thickness, width, and length combinations depending uponequipment and processing capabilities of various manufacturers and processors. Historic limitations of a product based upondimensions (thickness, width, and length) do not take into account current pro
39、duction and processing capabilities. To qualify anyproduct to a particular product specification requires all appropriate and necessary tests be performed and that the results meet thelimits prescribed in that product specification. If the necessary tests required by a product specification cannot b
40、e conducted, theproduct cannot be qualified to that specification. This general requirement standard contains permitted variations for the commonlyavailable sizes. Permitted variations for other sizes are subject to agreement between the customer and the manufacturer orprocessor, whichever is applic
41、able.3.1.1.4 Slabs, sheet bars, and skelp, though frequently falling in the foregoing size ranges, are not classed as plates.3.1.1.5 Coils are excluded from qualification to the applicable product specification until they are decoiled, leveled orstraightened, formed (if applicable), cut to length, a
42、nd, if required, properly tested by the processor in accordance with ASTMspecification requirements (see Sections 9-15, 18, and 19 and the applicable product specification).3 For referencedASTM standards, visit theASTM website, www.astm.org, or contactASTM Customer Service at serviceastm.org.
