ASTM E223-23

Standard Test Methods for Analysis of Sulfuric Acid

SIGNIFICANCE AND USE
3.1 These test methods provide for the classification of various grades of sulfuric acid and for the determination of various impurities. Acid strength and impurity levels are important factors in many uses of sulfuric acid.
SCOPE
1.1 These test methods cover the analysis of sulfuric acid.  
1.2 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.  
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.  
1.4 The analytical procedures appear in the following order:    
Sections  
Total Acidity  
8 to 16  
Baumé Gravity  
17 to 26  
Nonvolatile Matter  
27 to 33  
Iron  
34 to 43  
Sulfur Dioxide  
44 to 51  
Arsenic  
52 to 61  
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. Consult current OSHA regulations, suppliers’ Safety Data Sheets, and local regulations for all materials used in this specification. Specific hazards statements are given in Section 5.  
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.
