1.1 本规范涵盖用于钢铁制造的所有成分的铝合金脱氧产品，其形式为锭、棒、棒、锥、金块、丸或星。六种最常用的脱氧产品成分如表1所示。 （A） 应仅对铜、锌、镁、硅和铁进行分析，除非合同或订单要求测定其他元素，或在分析过程中指示存在大量浓度的其他元素。在后一种情况下，应确定并报告这些其他元素的数量，铜、锌、镁、硅、铁和“其他元素”的总量不得超过表最后一列中规定的数量。 除非合同或订单中另有规定，否则0.2 % 或更多的任何“其他元素”应构成“实质性浓度”，并要求报告该元素。 （B） 以下内容适用于本表中的所有规定限值:为了确定这些限值的符合性，应根据修约实践方法，将从分析中获得的观察值或计算值四舍五入到用于表示规定限值的数字右最后一位的最近单位 E29年 . 1.2 单位- 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）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 aluminum-alloy deoxidizing products of all compositions in the form of ingots, bars, rods, cones, nuggets, shot, or stars, for use in the manufacture of iron and steel. Six of the most commonly used deoxidizing product compositions are designated as shown in Table 1. (A) Analysis shall be made only for copper, zinc, magnesium, silicon, and iron unless the determination of additional elements is required by the contract or order, or the presence of other elements in substantial concentration is indicated during the course of the analysis. In the latter case, the amount of these other elements shall be determined, reported, and the total of copper, zinc, magnesium, silicon, iron, and “other elements” shall not exceed the specified amount prescribed in the last column of the table. Unless otherwise specified in the contract or order, 0.2 % or more of any “other element” shall constitute a “substantial concentration” and require that element to be reported. (B) The following applies to all specified limits in this table: For purposes of determining conformance to these limits, an observed value or a calculated value obtained from analysis shall be rounded to the nearest unit in the last right-hand place of figures used in expressing the specified limit in accordance with the rounding-off method of Practice E29 . 1.2 Units— 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. 1.3 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 establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 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.
