Standard Specification for Zinc — 3 стр.
Реферат

This specification covers zinc metal made from ore or other material by a process of distillation or by electrolysis in five grades as follows: LME grade, special high grade, high grade, intermediate grade, and prime western grade. The zinc metal shall be tested and conform to the chemical composition requirements of lead, iron, cadmium, aluminum, copper, tin, and non-zinc metals prescribed in this specification. The material shall be free of surface corrosion and adhering foreign matter. Representative samples from the molten metal during casting, and all part of these samples may be cast into shapes suitable for use in spectrochemical methods.

Область применения

1.1 This specification covers zinc metal made from ore or other material by a process of distillation or by electrolysis in five grades as follows:

1.1.1 LME Grade

1.1.2 Special High Grade

1.1.3 High Grade

1.1.4 Intermediate Grade

1.1.5 Prime Western Grade

Note 1: Certain continuous galvanizing grades are specified in Specification 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 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.
