Standard Specification for Tin Mill Products, General Requirements
ABSTRACT
This specification covers a group of common requirements which shall be applied to tin mill products. The steel shall be made by the open-hearth, electric-furnace, or basic-oxygen process. The steel shall conform to the chemical composition requirements as specified. Tin mill products shall undergo Rockwell testing and shall be in accordance with specified requirements.
SIGNIFICANCE AND USE
tin mill products; Abbreviated ratio tables; Aerated media polarization (AMP) test; Alloy-tin couple (ATC) test; Chromium coatings--specifications; Diphenylcarbazide method; Dissolution rate; Iron solution value; Metallic coatings--specifications; Pickle lag test; Tin crystal size test; Tin mill products--specifications; Total surface oil
SCOPE
1.1 This specification covers a group of common requirements which, unless otherwise specified in the purchase order or in an individual specification, shall apply to tin mill products.
1.2 In case of any conflict in requirements, the requirements of the purchase order, the individual material specification, and this general specification shall prevail in the sequence named.
Note 1—A complete metric companion to Specification A623 has been developedSpecification A623M; therefore no metric equivalents are presented in this specification.
1.3 The following safety caveat covers Annex A3 through Annex A10 of this specification: 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.
