This specification covers two types of commercial rolled zinc. Type I are coils or sheets cut from strip rolled zinc, and Type II are zinc plates such as boiler and hull plates produced by any rolling method. The products shall be produced by casting, rolling, and other processes found in mill product plant. The material shall be tested and conform to the required chemical composition. The testing of wrought zinc for determination of tensile properties shall be conducted. The testing of zinc for hardness shall be made on a Rockwell superficial hardness tester or on a microhardness tester. The determination of chemical composition shall be performed by either an appropriate chemical method or by optical emission spectrographic methods.

1.1 This specification covers two types of commercial rolled zinc as described in 1.2. It should be understood that the specification is general. Any closer limitations on permissible variations shall be a matter of agreement between the supplier (manufacturer) and the purchaser.

1.2 Rolled zinc is furnished in two types as follows:

1.2.1 Type A—Coils or sheets cut from strip (ribbon) rolled zinc and

1.2.2 Type B—Zinc plates such as boiler and hull plates produced by any rolling method.

1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

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 become familiar with all hazards including those identified in the appropriate Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, 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.
