    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/m3 air.

    1. Scope

    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.
