ASTM D5194-18
(Test Method)Standard Test Method for Trace Chloride in Liquid Aromatic Hydrocarbons
Standard Test Method for Trace Chloride in Liquid Aromatic Hydrocarbons
SIGNIFICANCE AND USE
4.1 Organic and inorganic chlorine compounds can have a deleterious effect on equipment and reactions in processes involving aromatic hydrocarbons.
4.2 Maximum chloride levels are often specified for process streams and for aromatic hydrocarbon products.
SCOPE
1.1 This test method covers the determination of total chloride (organic and inorganic) in liquid aromatic hydrocarbons and cyclohexane.
1.2 The test method is applicable to samples with chloride concentrations of 1 to 25 mg/kg.
1.3 Bromides and iodides, if present, will be calculated as chlorides.
1.4 Materials, such as styrene, that are polymerized by sodium biphenyl reagent cannot be analyzed by this test method.
1.5 In determining the conformance of the test results using this method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice E29.
1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.7 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 a specific hazard statement, see Section 7.
1.8 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.
