1.1 These test methods cover the analysis of aqueous hydrofluoric acid.

1.2 The analytical procedures appear in the following order:

Range, %SectionsSulfur dioxide 0.001 to 0.29 to 16 Total acidityto 7017 to 25 Iron 0.0001 to 0.526 to 35 Sulfuric acid0.001 to 1.0 36 to 44 Nonvolatile acidity0.01 to 245 to 53 Fluosilicic acid 0.0005 to 0.254 to 63

1.3 The values stated in SI units are to be regarded as the standard.

1.4This standard does not purport to address all of the safety problems, 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 hazards statements are given in Section 8.
