1.1 本试验方法涵盖了根据规范评估中间馏分燃料（如1D级和2D级柴油）潜在储存稳定性的程序 D975 . 1.2 本试验方法适用于新精炼燃料或已储存的燃料。 1.3 本试验方法适用于含有稳定剂添加剂的燃料以及不含此类添加剂的燃料。然而，与未添加分散剂添加剂的燃料相比，使用本试验方法，添加了分散剂添加剂（包括含分散剂的稳定性添加剂）的燃料可能排名不准确。 1.4 附录X1 提供了关于可能使用本试验方法的其他建议试验时间和温度的信息。 1.5 以国际单位制表示的数值应视为标准值。括号中给出的值仅供参考。 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。 有关特定警告声明，请参阅 4.1 , 6.2 , 6.3 和 7.4 . 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====== 5.1 当在相同条件下进行试验时，该试验方法的结果有助于将特定燃料样品与其他特定燃料样品或标准进行排序。使用本试验方法，与不含分散剂添加剂的燃料样品相比，含有分散剂添加剂的特定燃料样品（例如含有稳定性添加剂的分散剂）的排名不准确。 3. 本试验方法的目的不是将特定燃料与特定的现场处理和储存条件联系起来。不溶物的形成受储存容器中存在的材料和环境条件的影响。由于本试验方法是在标准化条件下在玻璃中进行的，因此可以在通用的基础上比较不同燃料的结果。

1.1 This test method covers a procedure for assessing the potential storage stability of middle distillate fuels such as Grade No. 1D and Grade No. 2D diesel fuels, in accordance with Specification D975 . 1.2 This test method is applicable to either freshly refined fuels or fuels already in storage. 1.3 This test method is suitable for fuels containing stabilizer additives as well as fuels containing no such additives. However, fuels additized with dispersant additives, including dispersant-containing stability additives, may be ranked inaccurately using this test method compared to fuels that are not additized with dispersant additives. 1.4 Appendix X1 provides information on other suggested test times and temperatures for which this test method may be used. 1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. 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 4.1 , 6.2 , 6.3 , and 7.4 . 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 results of this test method are useful in ranking a specific fuel sample against other specific fuel samples or standards when tested under identical conditions. Specific fuel samples containing dispersant additives, such as dispersant-containing stability additives, have shown inaccurate ranking against fuel samples that do not contain dispersant additives using this test method. 3 This test method is not meant to relate a specific fuel to specific field handling and storage conditions. The formation of insolubles is affected by the material present in the storage container and by the ambient conditions. Since this test method is conducted in glass under standardized conditions, the results from different fuels can be compared on a common basis.
