This specification covers electrical contact components made from copper tungsten by powder metallurgical procedures. The material shall conform to the chemical composition limits as agreed upon between the manufacturer and the user. Qualification tests for determination of physical properties shall be performed on production parts, wherever practical or applicable. The tests shall be determined after consideration of the function of the part.This specification covers zinc master alloys which are used in hot dip galvanizing for the purpose of adjusting the concentration of certain alloying elements in the molten zinc bath. The paper presented the chemical composition of these materials which include six master alloys of zinc aluminium; Type A-1, Type A-2, Type A-3, Type A-4, Type A-5, Type A-6, and one master alloy of zinc-antimony, Type S-1. The material covered by this specification shall be made of uniform quality and shall be free from harmful contamination. The alloys shall be tested and conform to the required chemical composition requirements.

ORDER

Scope

1.1 This specification covers zinc master alloys which are used in hot dip galvanizing for the purpose of adjusting the concentration of certain alloying elements in the molten zinc bath. covers the chemical composition of these materials which include six master alloys of zinc-aluminum (brightener) and one master alloy of zinc-antimony.

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

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 Safety Data Sheet (MSDS) 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.
