Standard Specification for Tin Mill Products, Electrolytic Tin Plate, Single Reduced
ABSTRACT
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.
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 A624) which is supplied in nominal thicknesses from 0.0061 to 0.0149 in. or SI units [as A624M] which is supplied in nominal thicknesses from 0.155 to 0.378 mm.
1.3 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
