1.1 This test method covers the measurement of chloride in aromatic hydrocarbons, their derivatives, and related chemicals as defined by the method. Aromatics typically do not have any source of chlorides other than organic. The presence of metallic or inorganic chlorides is theoretically possible but not likely and this method does not purport to address recovery of those compounds.
1.2 This test method is applicable to samples with chloride concentrations from 0.24 to 5.0 mg/kg. The test method limit of detection (LOD) is 0.07 mg/kg.
1.3 This test method is preferred over Test Method D5194 for products, such as styrene, that are polymerized by the sodium biphenyl reagent.
1.4 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.
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.6 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. For specific hazard statements, see Section 9.
