35、in. 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/ft2 47.10 kg/mkgm2 or heavier.(2) Over 48 in. 1200 mm in width and 7.350 lb/ft2 35.32
36、 kg/mkgm2 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)
37、do not take 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
38、 by a product 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 manufactu
