1.1 本试验方法包括使用手动或自动装置测定柴油和家用加热燃料的冷滤器堵塞点（CFPP）温度。 注1: 该试验方法在技术上等同于试验方法IP 309和EN 116. 1.2 手动装置和自动装置都适用于裁判目的。 1.3 本试验方法适用于柴油发动机和家用供暖装置中使用的馏分燃料，包括含有流量改善添加剂或其他添加剂的馏分燃料。 1.4 以国际单位制表示的数值应视为标准。本标准不包括其他计量单位。 1.5 警告 --汞已被许多监管机构指定为一种可能导致严重医疗问题的危险物质。汞或其蒸汽已被证明对健康有害，对材料具有腐蚀性。 处理汞和含汞产品时要小心。有关更多信息，请参阅适用的产品安全数据表（SDS）。当地或国家法律有可能禁止销售汞或含汞产品，或两者兼而有之。用户必须确定在其所在地销售的合法性。 1.6 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者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。 有关具体的警告声明，请参阅第节 7. . 1.7 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 燃料的CFPP适用于估计燃料在某些燃料系统中无故障流动的最低温度。 5.2 在欧洲轻型卡车中使用的柴油燃料的情况下，结果通常接近使用中的故障温度，除非燃料系统包含安装在暴露于天气的位置的纸过滤器，或者过滤器堵塞温度超过12 根据试验方法，低于浊点值°C 2500英镑 , D5771 , D5772 或 D5773 .家用供暖装置通常不那么关键，并且通常在略低于测试结果所示温度的温度下令人满意地运行。 5.3 从样品中获得的结果的差异 收到时 在45℃热处理后 °C持续30分钟可用于调查低温条件下性能不令人满意的投诉。

1.1 This test method covers the determination of the cold filter plugging point (CFPP) temperature of diesel and domestic heating fuels using either manual or automated apparatus. Note 1: This test method is technically equivalent to test methods IP 309 and EN 116. 1.2 The manual apparatus and automated apparatus are both suitable for referee purposes. 1.3 This test method is applicable to distillate fuels, including those containing a flow-improving or other additive, intended for use in diesel engines and domestic heating installations. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 WARNING —Mercury has been designated by many regulatory agencies as a hazardous substance that can cause serious medical issues. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. Use caution when handling mercury and mercury-containing products. See the applicable product Safety Data Sheet (SDS) for additional information. The potential exists that selling mercury or mercury-containing products, or both, is prohibited by local or national law. Users must determine legality of sales in their location. 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. For specific warning statements, see Section 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 ====== 5.1 The CFPP of a fuel is suitable for estimating the lowest temperature at which a fuel will give trouble-free flow in certain fuel systems. 5.2 In the case of diesel fuel used in European light duty trucks, the results are usually close to the temperature of failure in service except when the fuel system contains, for example, a paper filter installed in a location exposed to the weather or if the filter plugging temperature is more than 12 °C below the cloud point value in accordance with Test Method D2500 , D5771 , D5772 , or D5773 . Domestic heating installations are usually less critical and often operate satisfactorily at temperatures somewhat lower than those indicated by the test results. 5.3 The difference in results obtained from the sample as received and after heat treatment at 45 °C for 30 min can be used to investigate complaints of unsatisfactory performance under low temperature conditions.
