SUPERSEDED (see Active link, below)
ASTM A657 / A657M
1. Scope
1.1 This specification covers single- and double-reduced tin mill black plate electrolytically coated with chromium and chromium oxide. The steel is furnished in coils and cut lengths for use in the manufacture of cans, closures, crowns, and other products.
1.2 This specification is applicable to orders in either inch-pound units (as A626) which is supplied in thicknesses from 0.0050 to 0.0118 in. or in SI units [as A626M] which is supplied in thicknesses from 0.13 to 0.30 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 standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
