ASTM B6-00
(Specification)Standard Specification for Zinc
Standard Specification for Zinc
SCOPE
1.1 This specification covers zinc metal made from ore or other material by a process of distillation or by electrolysis in three grades as follows:
1.1.1 Special High Grade,
1.1.2 High Grade,
1.1.3 Prime Western.
Note 1--Certain continuous galvanizing grades are specified in B852. Other continuous galvanizing and controlled lead grades are not included in this specification but are covered by specific user purchasing specifications.
1.2 This specification does not cover zinc produced by "sweating" or remelting of secondary zinc.
1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
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 Material Data Sheet for this product/material as provided by the manufacturer, to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.
