1.1 这些试验方法包括测定废油、燃料和相关材料中的氯，包括:曲轴箱、液压油、柴油、润滑油和燃料油以及煤油，所有这些材料均含有<25%的氯 % （质量/质量）水。 1.1.1 如果样本包含大于25 % 金属钠优先与水反应，而不是与油中的卤化有机物反应。 1.1.2 溴化物和碘化物也以氯的摩尔数进行滴定和报告。该方法不检测氟，因为在滴定过程中AgF残留在溶液中，而AgI、AgBr和AgCl沉淀出来，因此可以检测到。 1.1.3 已证明可通过该方法检测到的一些氯化有机化合物包括三氯乙烷、二氯乙烷、三氯苯、一氯苯、氯十八烷、二氯甲烷、四氯乙烯、氟利昂和多氯联苯。这九种化合物代表了在废油中发现的主要类别的氯化化合物。 1.2 整个分析序列，包括采样、样品预处理、化学反应、提取和定量，以试剂盒形式提供，使用预分散和封装试剂。总体目标是提供一个简单、易于使用的程序，允许非技术人员在10分钟内在实验室环境内外进行测试 最小。 测试方法还提供了在没有套件的情况下运行测试的信息。 1.2.1 测试方法A预设为在1000时提供大于或小于结果 总氯含量为mg/kg（ppm），以满足废油的监管要求。 1.2.2 试验方法B提供的结果范围为200 mg/kg至4000 总氯mg/kg。 1.3 对于这两种测试方法，含量大于3的样品将产生正偏差 % （质量/质量）总硫。虽然不会出现假阴性结果，但应在高硫油上使用其他分析方法。 1.4 试验方法B，定量下限- 在为该测试方法开发统计数据的循环研究中，参与者被要求报告最接近100的结果 毫克/千克。因此，定量下限只能确定在870的范围内 毫克/千克 5. 至1180 毫克/千克 5. . 1.5 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.6 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 第节给出了具体的安全声明 3. , 6. 和 7. . 1.7 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）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》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 氯化物会导致设备腐蚀和催化剂中毒。氯化化合物在未完全燃烧时也会对健康造成危害。石油产品的氯含量在回收之前测定。 注1: 联邦法规规定，通常在回收之前必须测定废油中的氯含量。EPA法规40 CFR 261 如果用过的燃油被卤素污染（氯含量超过1000），则禁止销售 毫克/千克。除非能够证明氯含量为无机物或卤化有机物不是危险成分，否则此类油被视为危险废物。处理危险废物的成本比处理废油的成本高出许多倍。因此，用户、发电机、运输车、再加工机和收集器必须测试其处理的材料，以遵守法规，保持安全操作，并避免高昂的处置成本。 4.2 这些试验方法可用于确定所用石油产品何时满足或超过以氯化物测量的总卤素的要求。它是专门为二手油设计的，允许非技术人员在远程位置进行现场测试，以避免实验室测试的延迟。

1.1 These test methods cover the determination of chlorine in used oils, fuels, and related materials, including: crankcase, hydraulic, diesel, lubricating and fuel oils, and kerosene, all containing <25 % (mass/mass) water. 1.1.1 If the sample contains greater than 25 % water, the sodium metal reacts preferentially with the water rather than with the halogenated organics in the oil. 1.1.2 Bromide and iodide are also titrated and reported on a molar basis as chlorine. The method does not detect fluorine because AgF remains in the solution during the titration, while AgI, AgBr, and AgCl precipitate out and can therefore be detected. 1.1.3 Some of the chlorinated organic compounds that have been shown to be detectable by this method include trichloroethane, dichloroethane, trichlorobenzene, monochlorobenzene, chlorooctadecane, methylene chloride, perchloroethylene, Freon, and polychlorinated biphenyls. These nine compounds represent the major classes of chlorinated compounds that are found in used oils. 1.2 The entire analytical sequence, including sampling, sample pretreatment, chemical reactions, extraction, and quantification, is available in kit form using predispensed and encapsulated reagents. The overall objective is to provide a simple, easy to use procedure, permitting nontechnical personnel to perform a test in or outside of the laboratory environment in under 10 min. The test method also gives information to run the test without a kit. 1.2.1 Test Method A is preset to provide a greater than or less than result at 1000 mg/kg (ppm) total chlorine to meet regulatory requirements for used oils. 1.2.2 Test Method B provides results over a range from 200 mg/kg to 4000 mg/kg total chlorine. 1.3 For both test methods, positive bias will result from samples that contain greater than 3 % (mass/mass) total sulfur. While a false negative result will not occur, other analytical methods should be used on high sulfur oils. 1.4 Test Method B, Lower Limit of Quantitation— In the round-robin study to develop statistics for this test method, participants were asked to report results to the nearest 100 mg/kg. The lower limit of quantification could therefore only be determined to be in the range from 870 mg/kg 5 to 1180 mg/kg 5 . 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific safety statements are given in Sections 3 , 6 , and 7 . 1.7 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 ====== 4.1 Chlorinated compounds can lead to corrosion of equipment and poisoning of the catalyst. Chlorinated compounds also present a health hazard when incompletely combusted. Chlorine content of petroleum products is determined prior to their being recycled. Note 1: Federal Regulations mandate that often the chlorine content of used oil must be determined before recycling. EPA regulation 40 CFR 261 bars the sale of used oil for fuel if it is contaminated with halogens measured as chlorine at levels exceeding 1000 mg/kg. Such oil is considered to be a hazardous waste unless it can be proven that the chlorine content is inorganic or that the halogenated organics are not hazardous constituents. The cost of disposing of a hazardous waste is many times higher than the cost of used oil disposal. Therefore it is critical for users, generators, haulers, reprocessors, and collectors to test the material they handle in order to comply with regulations, maintain safe operations, and avoid high disposal costs. 4.2 These test methods can be used to determine when a used petroleum product meets or exceeds requirements for total halogens measured as chloride. It is specifically designed for used oils, permitting on-site testing at remote locations by nontechnical personnel to avoid the delays of laboratory testing.
