1.1 本试验方法包括通过膜过滤测定原油中的沉淀物。该试验方法已针对沉积物高达约0.15的原油进行了验证 % 按质量计算。 1.2 本试验方法的可接受测量单位为质量 %, 而是一个转化为体积的方程 % 提供（参见 附注6 ). 1.3 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.4 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 6.1 和 附件A1 . 1.5 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 原油沉积物含量的知识在炼油厂操作和原油商业中都很重要。

1.1 This test method covers the determination of sediment in crude oils by membrane filtration. This test method has been validated for crude oils with sediments up to approximately 0.15 % by mass. 1.2 The accepted unit of measure for this test method is mass %, but an equation to convert to volume % is provided (see Note 6 ). 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.4 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 6.1 and Annex A1 . 1.5 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 A knowledge of the sediment content of crude oil is important both in refinery operations and in crude oil commerce.
