ASTM D5776-2007e1 用电位滴定法测定芳烃溴值的标准试验方法
【英文标准名称】: Standard Test Method for Bromine Index of Aromatic Hydrocarbons by Electrometric Titration 【原文标准名称】: 用电位滴定法测定芳烃溴值的标准试验方法 【标准号】: ASTM D5776-2007e1 【标准状态】: 现行 【国别】: 【发布日期】: 2007 【实施或试行日期】: 【发布单位】: 美国材料与试验协会(US-ASTM)【起草单位】: D16.04【标准类型】: (Test Method)【标准水平】: ()【中文主题词】: 芳烃;溴;试验方法;滴定法【英文主题词】: aromatic hydrocarbons; bromine index; bromine-reactive; electrometric titration【摘要】: 1.1 This test method determines the amount of bromine-reactive material in aromatic hydrocarbons and is thus a measure of trace amounts of unsaturates in these materials. It is applicable to materials having bromine indexes below 500.1.2 This test method is applicable to aromatic hydrocarbons containing no more than trace amounts of olefins and that are substantially free from material lighter than isobutane and have a distillation end point under 288176;C (550176;F).1.3 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 E 29.1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.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.
