1.1 除非特定产品规范中另有规定，否则本规范规定了锌和锌合金产品常见化学分析的订购信息、标记和取样的一般要求，并应适用于本规范 B6 , B69 , B86 , 第240页 , 第327页 , B418 , B750 , B792型 , B793型 , B833 , B852 , B860 , B892型 , B894 , B897 , B907型 , B943 , B960 , 1989年 , B997型 , 2013年1月 和 2022年1月 在其中引用的范围内。 1.2 尽管本规范规定了一般要求，但并不限制客户和供应商之间达成协议后，客户可以根据个人需要更改这些要求。 1.3 本规范中未包含的化学成分、物理和机械性能以及所有其他要求应在产品规范中规定。 1.4 以英寸磅为单位的数值应视为标准。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。这适用于仅指定国际单位制的情况。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任熟悉所有危险，包括制造商提供的本产品/材料的适当数据表（SDS）中确定的危险，制定适当的安全、健康和环境实践，并在使用前确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

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.
