These test methods described manual procedures for the determination of fluoride in various types of samples. The procedures outlined, consequently, were appropriate to the analysis of ambient air samples taken by diverse sampling techniques when properly applied.
Formerly under the jurisdiction of Committee D22 on Air Quality, these test methods were withdrawn in February 2010 in accordance with subsection 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
1.1 These test methods describe manual procedures for the determination of fluoride in various types of samples. The procedures outlined, consequently, are appropriate to the analysis of ambient air samples taken by diverse sampling techniques when properly applied.
1.2 The values stated in SI units are to be regarded as the 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 and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in 10.7.1.3 and Ref (9).
