1.1 这些试验方法包括铁矿石、精矿和团聚体中锰的测定。包括以下两种测试方法: 小节 试验方法A（焦磷酸盐（电位法）） 8 – 15 试验方法B（高碘酸盐（分光光度法）） 16 – 22 1.2 试验方法A涵盖了2.5%至15.0%范围内锰的测定。试验方法B涵盖了0.01%至5.00%范围内的锰测定。 注1: 根据实践，该试验方法的下限设定为实验室间研究中测试的最低等级材料的50%相对误差 E1601 . 1.3 以国际单位制表示的数值应视为标准。本标准不包括其他计量单位。 1.4 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者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。 1.5 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。 ====意义和用途====== 4.1 本试验方法旨在符合铁矿石、精矿和团聚体中锰含量的成分规范。假设所有使用这些程序的人员都是经过培训的分析员，能够熟练、安全地执行常见的实验室程序。预计工作将在设备齐全的实验室进行，并遵循适当的废物处理程序。必须遵循适当的质量控制实践，如指南中所述 E882 .

1.1 These test methods cover the determination of manganese in iron ores, concentrates, and agglomerates. The following two test methods are included: Sections Test Method A (Pyrophosphate (Potentiometric)) 8 – 15 Test Method B (Periodate (Spectrophotometric)) 16 – 22 1.2 Test Method A covers the determination of manganese in the range from 2.5 % to 15.0 %. Test Method  B covers the determination of manganese in the range of 0.01 % to 5.00 %. Note 1: The lower limit for this test method is set at 50 % relative error for the lowest grade material tested in the interlaboratory study in accordance with Practice E1601 . 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 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. 1.5 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. ====== Significance And Use ====== 4.1 This test method is intended to be used for compliance with compositional specifications for manganese content in iron ores, concentrates, and agglomerates. It is assumed that all who use these procedures will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory and that proper waste disposal procedures will be followed. Appropriate quality control practices must be followed such as those described in Guide E882 .
