This specification establishes general requirements, unless otherwise specified in the specific product specification, for zinc and zinc alloy products. Final product (ingots, slabs, jumbos, etc.) shall conform to the chemical composition requirements prescribed in the applicable product specification. The determination of chemical composition shall be made in accordance with suitable spectrochemical or chemical methods. Methods of sampling for chemical analysis includes: (1) sampling during casting of ingots, slabs, blocks or jumbos, and wrought products, (2) sampling in the event of a dispute or if the alloy is at the customer’s plant, (3) sampling of zinc alloy ingots for routine testing, nominal quality, non-dispute situations, and (4) sampling of final product castings. Sampling may be done by sawing, milling, drilling, turning, or clipping. Color code requirements for the alloy are detailed.
