Standard Specification for Zinc and Zinc Alloy Wire for Thermal Spraying (Metallizing) for the Corrosion Protection of Steel

Fecha:
2020-04-24 /Active
Abstract:

This specification covers zinc and zinc alloy wire used to deposit zinc coatings by thermal spraying (metallizing) for the corrosion protection of steel and iron. Zinc and zinc alloy wire provided under this specification is intended for use in oxy-fuel and electric arc thermal spraying equipment. The zinc used to manufacture the wire shall conform to the requirements for high grade zinc (Z15001) or special high grade zinc (Z13001). The wire shall conform to the chemical requirements for aluminum, cadmium, copper, iron, lead, tin, antimony, silver, bismuth, arsenic, nickel, magnesium, molybdenum, titanium, and zinc. The wire shall be clean and free of corrosion, adhering foreign material, scale, seams, nicks, burrs, bends or kinks which would interfere with the operation of thermal spraying equipment. The wire shall uncoil readily and shall be a continuous length per spool, coil, or drum. Splices or welds are permitted, provided that they do not interfere with the thermal spray equipment or coating process.

Scope:

1.1 This specification covers zinc and zinc alloy wire used to deposit zinc coatings by thermal spraying (metallizing) for the corrosion protection of steel and iron. Zinc and zinc alloy wire provided under this specification is intended for use in oxy-fuel and electric arc thermal spraying equipment. Additional zinc alloy compositions used in thermal spraying primarily for electronic applications are found in Specification B943.

1.2 Zinc alloy wire compositions used in thermal spraying primarily for electronic applications are found in Specification B943.

1.3 Zinc alloy wire compositions used as solders are found in Specification B907.

1.4 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.

1.5 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, health, and environmental practices, and determine the applicability of regulatory limitations prior to use.

1.6 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.
