Application: Anode material in galvanic zinc baths
This Standard specifies requirements for zinc oxide for use as an ingredient of pyrotechnic smoke compositions.
Requirements for four grades of primary zinc - 99.99%, 99.95%, 99.5% and 98.5%.
Material Description. This coating system must be free of hexavalent chromium, per GMW3059 requirements. The plating shall be shown on the part drawing. Table 1 lists the common plating thickness codes covered by this specification. It is recommended to use these common codes to avoid product...
This Standard specifies requirements for a zinc stearate for use as a pressing aid in the pelleting of certain HE and pyrotechnic materials.
This standard describes zinc orthophosphate (ZOP) corrosion inhibitor in dry and liquid forms for use in the treatment of potable water, wastewater, or reclaimed water. Purpose The purpose of this standard is to provide the minimum requirements for ZOP, including physical,...
Purpose This specification covers the requirements for electrodeposited zinc plating. Application This process has been used typically to provide corrosion resistance to metal parts, but usage is not limited to such applications. Unless otherwise stated on the engineering drawing, high...
This part of ISO 6509 specifies a method for the determination of dezincification depth of copper alloys with zinc exposed to fresh, saline waters or drinking water. The method is intended for copper alloys with a mass fraction of zinc more than 15 %. This part of ISO...
This standard covers the requirements for pretreatment material for automotive bodies. The pretreatment materials are composed alkaline degreaser, surface conditioner and phosphate agent. Zinc-phosphate material is mainly composed zinc-phosphate, with such additive as manganese and...
Zinc corrodes slowly relative to steel; in most atmospheres and many waters, the average rate of attack is about one twenty-fifth that of steel. This Digest explains how zinc coating protects steel galvanically and provides sacrificial protection. 4 pages.
1. SCOPE This specification defines the performance requirements for a cadmium or zinc protective coating on iron and steel surfaces, together with additional special finishes for zinc plate, to improve protective and/or appearance properties. Cadmium may be used in place of...
