1.1 本试验方法包括测定煤中的总氟和总氯。含200的样品 mg/kg至4000 氯和20 mg/kg mg/kg至100 可以直接分析mg/kg的氟。 1.1.1 该方法可用于测定煤中的总溴。对于总溴的测定，不会给出精度和偏差声明。 1.2 以国际单位制表示的数值应视为标准值。国际单位制后括号中给出的值仅供参考，不被视为标准值。 1.3 在使用本方法确定试验结果是否符合适用规范时，应根据四舍五入对结果进行四舍五入- 脱离实践的方法 E29年 . 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 本试验方法涵盖了煤中氯和氟含量的测量。这些卤化物会导致排放，产生一些不良的环境后果。

1.1 This test method covers the determination of total fluorine and total chlorine in coal. Samples containing 200 mg/kg to 4000 mg/kg of chlorine and 20 mg/kg to 100 mg/kg of fluorine can be analyzed directly. 1.1.1 It is possible for this method to be used for the determination of total bromine in coal. No precision and bias statement will be given for the determination of total bromine. 1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard. 1.3 In determining the conformation of the test results using this method to applicable specifications, results shall be rounded off in accordance with the rounding-off method from Practice E29 . 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 covers the measurement of the chlorine and fluorine contents in coal. These halides can contribute to emissions with some undesirable environmental consequences.
