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.  
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.

Electronic grade solder alloys and fluxed and non-fluxed solid solders for electronic soldering applications are not taken into account here. Solder alloys shall adhere to chemical composition requirements specified for the following flux types: Types R, RMA, and RA, which are composed of Grade WW or WG gum rosin; Type OA, which is composed of water-soluble organic materials; Type OS, which is composed of water-insoluble organic materials; and Type IS, which is composed of inorganic saltsor acids. Solders shall also meet physical property requirements such as paste texture, powder mesh size, viscosity, solder pool, and dryness, and pass performance requirements such as chlorides and bromides test, copper mirror test, and visual inspection.
