1.1 本规范涵盖了锌合金的等级，通常称为连续镀锌等级（CGG）合金，其含有铝或铝和铅，用于钢板的连续热浸镀锌。由原生锌制成的CGG品位的成分如所示 表1 。由二次锌制成的等级的例外情况见脚注C。 1.2 规范中规定的CGG合金 B852型 用于钢板的连续热浸镀锌，以生产规范中规定的产品 A653/A653米 . 1.3 规范中未包含的其他合金成分 B852型 ，并由生产商和用户商定，可用于连续镀锌。 1.4 以英寸-磅单位表示的数值应视为标准值。括号中给出的数值是国际单位制的数学转换，仅供参考，不被视为标准。 1.5 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任熟悉所有危险，包括制造商提供的该产品/材料的适当安全数据表（SDS）中确定的危险，建立适当的安全、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》中确立的国际公认标准化原则制定的。

1.1 This specification covers grades of zinc alloys, commonly known as Continuous Galvanizing Grade (CGG) alloys that contain aluminum, or aluminum and lead, that are used in continuous hot-dip galvanizing of steel sheet. The compositions for CGG grades made from primary zinc are shown in Table 1 . Exceptions for grades made from secondary zinc are found in footnote C. 1.2 CGG alloys specified in Specification B852 are used in continuous hot-dip galvanizing of steel sheet to produce product, as specified in Specification A653/A653M . 1.3 Other alloy compositions not included in Specification B852 , and as may be agreed upon between the producer and the user, may be used for continuous galvanizing. 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. 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 Safety 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.
