(Specification)Standard Specification for Tin Mill Products, Black Plate, Double Reduced
Standard Specification for Tin Mill Products, Black Plate, Double Reduced
ABSTRACT
This specification covers doubled-reduced black plate tin mill products produced from low-carbon cold-reduced steel, furnished in coils and cut sizes, for use predominantly in the manufacture of containers. The product, which is normally supplied with trimmed edges, may be specified "as rolled," without the removal of the rolling solution, and with no additional surface or oiling treatment, or "cleaned" with the rolling solution removed, with or without surface treatment and oiling. The rolling direction must be specified on cut lengths and will be indicated by underlining the slit (rolling width) dimension. Surfaces may polished in either the ground roll finish (base metal finish), or smooth finish with grit lines (7C finish).
SCOPE
1.1 This specification covers double-reduced black plate, produced from low-carbon cold-reduced steel, furnished in coils and cut sizes, for use predominantly in the manufacture of containers. The product may be specified “as rolled,” without the removal of the rolling solution, and with no additional surface or oiling treatment. It may also be specified “cleaned” with the rolling solution removed, with or without surface treatment and oiling. This product is normally supplied with trimmed edges.
1.2 This specification is applicable to orders in either inch-pound units (as A650) which is supplied in thicknesses 0.0050 in. to 0.0113 in. or SI units [as A650M] which is supplied in thicknesses from 0.127 to 0.287 mm.
1.3 The values stated in either inch-pound or SI units are to be regarded as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with this specification.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
