本文件规定了使用逐步冷却技术确定浊点的方法，该技术通过光学检测模式的自动设备类型执行。 该方法适用于馏出燃料、脂肪酸甲酯（FAME）和石蜡柴油燃料，包括其混合物，以及含有流动改进剂或其他添加剂的燃料，拟用于柴油发动机和家用加热装置。 该方法可应用于其他产品，如植物油或润滑剂，但这些产品尚未在实验室间研究（ILS）期间进行评估，没有可用的精度数据。

This document specifies a method to determine cloud point using a step-wise cooling technique that is executed by means of automated equipment types with optical detection mode. The method is applicable to distillate fuels, fatty-acid methyl esters (FAME) and paraffinic diesel fuels, including blends thereof, as well as those containing flow-improvers or other additives, intended for use in diesel engines and domestic heating installations. The method can be applied to other products such as vegetable oils or lubricants, but these kinds of products have not been evaluated during the interlaboratory study (ILS), no precision data are available.
