1.1 本试验方法描述了通过双纸带取样器在经过化学处理的纸带上自动分离和收集大气中酸性氟化物的颗粒和气体形式。采样器可编程为收集和存储从几分钟到3小时的时间段内获得的单个空气样本。30.5米（100英尺）胶带将允许无人值守操作，以自动收集多达600个样本。 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 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。 1.4 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 本试验方法提供了一种自动分离和收集大气颗粒物和酸性气体氟化物样品的方法。 5.2 由于样品收集在干胶带上，因此样品的形式允许使用少量洗脱液洗脱氟化物含量。因此，该方法允许对短至几分钟的时间段内采集的空气样本进行分析。

1.1 This test method describes the automatic separation and collection on chemically treated paper tapes of particulate and gaseous forms of acidic fluorides in the atmosphere by means of a double paper tape sampler. The sampler may be programmed to collect and store individual air samples obtained over time periods from several minutes to 3 h. A 30.5-m (100-ft) tape will allow unattended operation for the automatic collection of up to 600 samples. 1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are included for information only and are not considered standard. 1.3 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. 1.4 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 provides a means of automatically separating and collecting atmospheric particulate and acidic gaseous fluoride samples. 5.2 Since the samples are collected on dry tapes, the samples are in a form which allows elution of the fluoride content with a small volume of eluent. Consequently, the method allows analyses of air samples taken for a time period as short as several minutes.
