1.1 This test method covers determination of the assay of nitric acid by total acidity. This test method is suitable for concentrations between approximately 50 and 70 %, calculated as nitric acid. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 Review the current Safety Data Sheets (SDS) for detailed information concerning toxicity, first aid procedures, and safety precautions. 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 and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 8. 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.
