This specification covers single-reduced electrolytic tin plate produced from low-carbon cold-reduced steel furnished in coils and cut sizes for use in the manufacture of cans, closures, crowns, and other products. The material shall conform to the coating weight [mass] test values. Details on standard heavy marking system for differential electrolytic tin plate shall be described. Standard light side marking system for differential electrolytic tin plate shall also be indicated. Chemical treatments such as cathodic sodium dichromate treatment and sodium dichromate dip treatment shall be applied after the tin coating has been deposited and immediately preceding the oiling, to control tin oxide formation and growth.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers single-reduced electrolytic tin plate produced from low-carbon cold-reduced steel furnished in coils and cut sizes for use in the manufacture of cans, closures, crowns, and other products. It is furnished in commercially available tin coating weights [masses], and is normally supplied with a trimmed edge.

1.2 This specification is applicable to orders in either inch-pound units (as A 624) which is supplied in nominal thicknesses from 0.0061 to 0.0149 in. or SI units [as A 624M] which is supplied in nominal thicknesses from 0.155 to 0.378 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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
