1.1 本规范涵盖了一组通用要求，除非单独规范中另有规定，否则这些要求应适用于符合以下ASTM规范的铁合金和其他合金材料: 规范标题 ASTM名称 锰铁 A99型 硅铁 A100 铬铁 A101号 钒铁 A102号 钼铁 A132型 氧化钼产品 A146型 硼铁 A323飞机 钛铁 A324飞机 铬金属 A481 铬铁硅 A482/A482M 锰硅合金 A483/A483M 钙硅合金 A495 铌铁 A550型 电解金属锰 A601/A601M 氧化镍烧结矿 A636型 锰铁硅 A701/A701M 钢脱氧和合金化用废钛 A845 钢脱氧和合金化用废铝 A846 金属硅 A922型 1.2 本规范还涵盖了一组补充要求，这些补充要求可适用于上述规范，如其中所示。当需要额外的测试或检查时，提供这些测试或检查，并且仅当买方在订单中单独指定时才适用。 1.3 如果个别规范的要求与本通用规范的要求相冲突，应以前者为准。 1.4 单位- 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值可能不是精确的等效值；因此，每个系统应相互独立使用。将两个系统的值合并可能会导致不符合标准。 1.4.1 本规范以英寸-磅单位和国际单位表示（在本文中，国际单位显示在括号中）；但是，除非采购订单或合同规定了适用的M规格名称（国际单位制），否则英寸- 磅单位应适用。 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。 1.6 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 a group of common requirements that, unless otherwise specified in an individual specification, shall apply to ferroalloys and other alloying materials under each of the following ASTM specifications: Title of Specification ASTM Designation Ferromanganese A99 Ferrosilicon A100 Ferrochromium A101 Ferrovanadium A102 Ferromolybdenum A132 Molybdenum Oxide Products A146 Ferroboron A323 Ferrotitanium A324 Chromium Metal A481 Ferrochrome-Silicon A482/A482M Silicomanganese A483/A483M Calcium-Silicon Alloys A495 Ferrocolumbium A550 Electrolytic Manganese Metal A601/A601M Nickel Oxide Sinter A636 Ferromanganese Silicon A701/A701M Titanium Scrap for Use in Deoxidation and Alloying of Steel A845 Aluminum Scrap for Use in Deoxidation and Alloying of Steel A846 Silicon Metal A922 1.2 This specification also covers a group of supplementary requirements which may be applied to the above specifications as indicated therein. These are provided for use when additional testing or inspection is desired and apply only when specified individually by the purchaser in the order. 1.3 In case of conflict between the requirements of the individual specification and this general specification, the former shall prevail. 1.4 Units— The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 1.4.1 This specification is expressed in both inch-pound units and in SI units (within the text, the SI units are shown in brackets); however, unless the purchase order or contract specifies the applicable M specification designation (SI units), the inch-pound units shall apply. 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 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.
