标准简介
适用范围:
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.1.1 These test methods cover the analysis of hydrochloric 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 Sulfated Ash 27 to 34 Iron 35 to 44 Color 45 to 52 Total Sulfur 53 to 591.5 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, 30.1, 39.7, and 48.4.1.6 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.
