Standard Test Method for Measurement of Fluorides in Workplace Atmospheres by Ion-Selective Electrodes 用离子选择电极测量工作场所大气中氟化物的标准试验方法
发布日期: 2018-12-01
1.1 本试验方法涵盖在某些工业工作场所中发现的气态氟化物(例如氟化氢)和颗粒氟化物的同时收集和单独测量。收集的气态氟化物和颗粒氟化物以氟化物的形式报告。该方法包括样品收集、制备和氟化物测量。 1.2 该程序不适用于气态氟化合物(例如氟碳化合物或氟硫化合物)的收集或分析。 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 本试验方法在工业大气中通常遇到的范围内收集和定量颗粒和气体氟化物的能力使其适用于工业卫生评估和控制目的。本试验方法的建议范围为0.005至5 mg F − /m 3. 空气
1.1 This test method covers the simultaneous collection and separate measurements of gaseous fluoride (for example, hydrogen fluoride) and particulate fluoride found in certain industrial workplaces. The gaseous fluorides and particulate fluorides collected are reported in terms of fluoride. The method covers sample collection, preparation, and fluoride measurement. 1.2 The procedure is not applicable to the collection or analysis of gaseous fluoro compounds (for example, fluorocarbon or fluorosulfur compounds). 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 The capability of this test method to collect and quantitate both particulate and gaseous fluorides over the ranges normally encountered in industrial atmospheres makes it applicable for industrial hygiene evaluation and control purposes. The recommended range of this test method is from 0.005 to 5 mg F − /m 3 air.
