1.1 本试验方法涵盖铁矿石、精矿和团块中磷的测定。 1.2 本试验方法包括在0.01范围内测定磷 % 至1.00 %. 1.3 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.4 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。 1.5 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。 ====意义和用途====== 5.1 本试验方法旨在符合磷含量的成分规范。假设所有使用这些程序的人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。预计工作将在配备适当的实验室进行，并遵循适当的废物处理程序。应遵循适当的质量控制实践，如指南中所述 E882 .

1.1 This test method covers the determination of phosphorus in iron ores, concentrates, and agglomerates. 1.2 This test method covers the determination of phosphorus in the range from 0.01 % to 1.00 %. 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 ====== 5.1 This test method is intended to be used for compliance with compositional specifications for phosphorus content. 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 shall be followed, such as those described in Guide E882 .
