17、mensions and mass (Note 1) in SI units. The values listed are not exact conversionsof the values in Tables 1 to 31 inclusive but are, instead, rounded or rationalized values. Conformance to Annex A1 is mandatorywhen the “M” specification designation is used.NOTE 1The term “weight” is used when inch-
18、pound units are the standard; however, under SI, the preferred term is “mass.”1.3 Annex A2 lists the dimensions of some shape profiles.1.4 Appendix X1 provides information on coil as a source of structural products.1.5 Appendix X2 provides information on the variability of tensile properties in plat

Such requirements are provided for use where additional testing or additionalrestrictions are required by the purchaser, and apply only where specified individually in the purchase order.1.9 In case of any conflict in r

22、 requirements of this general requirements specification or the applicable productspecification.1.11 For purposes of determining conformance with this general requirements specification and the applicable productspecification, values are to be rounded to the nearest unit in the right-hand place of f

24、 contain any mandatory requirements.1.13 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SIunits are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system is to be usedindependent

35、. 200 mm in width and 0.230 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/ft247.10 kg/m2 or heavier.(2) Over 48 in. 1200 mm in width and 7.350 lb/ft235.32 kg/m2
36、or heavier.3.1.1.3 DiscussionSteel 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 tak
37、e into account current production 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 prod
38、uct specification cannot be 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 orproc
39、essor, whichever is applicable.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 app
