1.1 This test method covers determination of the assay of nitric acid by total acidity.

1.2 This test method is suitable for concentrations between approximately 50 % and 70 %, calculated as nitric acid.

1.3 The following applies for the purposes of determining the conformance of the test results using this test method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice E29.

1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 8.

1.6 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.

4.1 This test method provides a means for assaying nitric acid, based on total acidity. The concentration of nitric acid is important in many of the uses of nitric acid, including specification compliance and manufacturing control.
