1.1 These test methods cover the analysis of aqueous hydrofluoric acid. 1.2 The analytical procedures appear in the following order: Range, % Sections Sulfur dioxide 0.001 to 0.2 9 to 16 Total acidity to 70 17 to 25 Iron 0.0001 to 0.5 26 to 35 Sulfuric acid 0.001 to 1.0 36 to 44 Nonvolatile acidity 0.01 to 2 45 to 53 Fluosilicic acid 0.0005 to 0.2 54 to 631.3 The values stated in SI units are to be regarded as the standard. 1.4 This 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. |
