ASTM E224-16

Standard Test Methods for Analysis of Hydrochloric Acid

SIGNIFICANCE AND USE
3.1 These test methods provide for the classification of various grades of hydrochloric acid and for the determination of various impurities. Acid strength and impurity levels are important factors in many uses of hydrochloric acid.
SCOPE
1.1 These test methods cover the analysis of hydrochloric acid.  
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.  
1.3 The analytical procedures appear in the following order:    
Sections  
Total Acidity  
8 to 16  
Baumé Gravity  
17 to 26  
Sulfated Ash  
27 to 34  
Iron  
35 to 44  
Color  
45 to 52  
Total Sulfur  
53 to 59  
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 hazards statements are given in Section 5 and 30.1, 39.7, and 48.4.
