Significance and Use:

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.


1.1 This test method covers the simultaneous collection and separate measurements of gaseous and particulate fluoride found in certain industrial workplaces. The gaseous inorganic fluorides collected are reported in terms of fluoride; the procedure is not applicable to the collection or analysis of other fluoride-bearing gases (for example, fluorocarbon or fluorosulfur compounds). This test method covers sample collection, preparation, and fluoride measurement.

1.2 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 and health practices and determine the applicability of regulatory limitations prior to use.
