1、Designation: A 625/A 625M 03Standard Specification forTin Mill Products, Black Plate, Single-Reduced1This standard is issued under the fixed designation A 625/A 625M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last

2、 revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This specification covers single-reduced

3、 black plateproduced from low carbon, cold-reduced steel, furnished incoils and cut sizes, for use in the manufacture of containers,closures, signs, toys and other products, as well as for platingapplications.1.2 It may be supplied dry or oiled and with or withoutsurface treatment. This product is n

4、ormally supplied with atrimmed edge.1.3 This specification is applicable to orders in eitherinch-pound units (as A 625), which is supplied in thicknessesfrom 128-lb base weight (0.0141 in.) and lighter, or SI units (asA 625M), which is supplied in thicknesses from 0.358 mm andlighter.1.4 The values

5、stated in either inch-pound or SI units are tobe regarded as standard. Within the text, the SI units are shownin brackets. The values stated in each system are not exactequivalents; therefore, each system must be used indepen-dently of the other. Combining values from the two systemsmay result in no
