ABSTRACT
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.
SCOPE
1.1 This specification establishes general requirements, unless otherwise specified in the specific product specification, for ordering information, marking, and sampling for chemical analysis common to zinc and zinc alloy products and shall apply to Specifications B6, B69, B86, B240, B327, B418, B750, B792, B793, B833, B852, B860, B892, B894, B897, B907, B943, B960, B989, B997, B1013, and B1022 to the extent referenced therein.  
1.2 Although this specification establishes general requirements, it does not restrict that, by agreement between customer and supplier, these requirements may be altered by a customer to suit individual need.  
1.3 The chemical composition, physical and mechanical properties, and all other requirements not included in this specification shall be prescribed in the product specification.  
1.4 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. This applies except where SI units only are specified.  
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 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.

Chemical analysis shall be performed on the samples which shall be taken during pouring the casting prior to working or during subsequent processing, such as rolling or cutting. The material shall conform to the product analysis variation in the chemical composition specifications for antimony, arsenic, tin, copper, silver, bismuth, zinc, tellurium, nickel, iron, and lead. Tension and hardness tests shall also be conducted on the specimens which shall be taken in the direction of rolling from the material in the final condition of rolling and heat treatment or in the case of continuously cast sheet in the casting direction and as cast state. The lead products shall be uniform in quality and hardness, smooth, commercially straight and flat, and free of injurious imperfections such as pits, dents, scratches, laminations, grit, foreign matter, porosity, or waves that may affect the serviceability of material.
