1.1 本试验方法包括测定0.40 % m/m（含残余组分的馏出燃料油）和0.50 % m/m，最大粘度为55 cSt（mm 2. /s） 在100 °C。由于存在大量不溶性有机或无机材料以外的因素，某些燃料可能超过本试验方法规定的最大过滤时间。该试验方法可用于评估设计用于加速老化过程的燃料预处理后的总沉积物。 1.2 以国际单位制表示的值应视为标准值。本标准不包括其他测量单位。 1.3 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。 有关特定警告声明，请参阅 7.2 , 7.3 , 附件A1 和 X1.6.1 . 1.4 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《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 5.1 残余燃料油中沉积物的可评估量会导致处理设施结垢，并给燃烧器机构带来问题。沉积物可能积聚在储罐、滤网或燃烧器部件上，从而阻碍油从储罐流向燃烧器。

1.1 This test method covers the determination of total sediment up to 0.40  % m/m for distillate fuel oils containing residual components and to 0.50 % m/m in residual fuel oils having a maximum viscosity of 55 cSt (mm 2 /s) at 100 °C. Some fuels can exceed the maximum filtration time specified in this test method due to factors other than the presence of significant quantities of insoluble organic or inorganic material. This test method can be used for the assessment of total sediment after regimes of fuel pretreatment designed to accelerate the aging process. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 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 7.2 , 7.3 , Annex A1 , and X1.6.1 . 1.4 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 Appreciable amounts of sediment in a residual fuel oil can cause fouling of facilities for handling, and give problems in burner mechanisms. Sediment can accumulate in storage tanks, on filter screens, or on burner parts, resulting in obstruction of the flow of oil from the tank to the burner.
