1.1 本试验方法涵盖了各种烃流中痕量过氧化物的测定。典型烃流列表见 附录X2 . 1.2 本试验方法适用于测定石油液体中的过氧化物，包括但不限于0.1 mg/kg至100 mg/kg活性氧范围内的1,3-丁二烯、苯乙烯、甲基环己烷和α-烯烃。活性氧的检测限（LOD）为0.03mg/kg，定量限（LOQ）为0.11mg/kg活性氧。上限已由校准范围确定。 注1: LOD和LOQ是使用在开发该测试方法期间获得的数据计算的。 1.3 在使用本试验方法确定试验结果是否符合适用规范时，应按照《实施规程》的四舍五入方法对结果进行四舍五舍五入 E29 . 1.4 单位-- 以国际单位制表示的值应被视为标准值。 本标准不包括其他计量单位。 1.5 本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 关于具体的危害声明，请参见第节 9 . 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 =====意义和用途====== 5.1 本试验方法适用于测定各种烃流中过氧化氢、有机氢过氧化物和有机过氧化物作为总活性氧的量，以进行产品的质量控制和质量保证。

1.1 This test method covers the determination of trace peroxides in various hydrocarbon streams. A list of typical hydrocarbon streams can be found in Appendix X2 . 1.2 This test method is applicable to the determination of peroxides in petroleum liquids including, but not limited to, 1,3-butadiene, styrene, methylcyclohexane, and alpha olefins in the range of 0.1 mg/kg to 100 mg/kg active oxygen. The limit of detection (LOD) is 0.03 mg/kg for active oxygen and the limit of quantitation (LOQ) is 0.11 mg/kg active oxygen. The upper limit has been determined by the calibration range. Note 1: LOD and LOQ were calculated using data obtained during development of this test method. 1.3 In 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 . 1.4 Units— The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 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. For specific hazard statements, see Section 9 . 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. ====== Significance And Use ====== 5.1 This test method is suitable for determining the quantity of hydrogen peroxide, organic hydroperoxides, and organic peroxides as total active oxygen in various hydrocarbon streams for both quality control and quality assurance of the product.
