Significance and Use
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.
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:
|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|
