本文件规定了测定石油产品倾点的方法。还描述了适用于测定燃油、重润滑油基础油和含有残余燃料成分的产品的较低倾点的单独程序。 本文件中描述的程序不适用于原油。 注:现有设备使用的自动化程序与本文件中描述的程序类似。然而，其精度尚未确定[1]。 [1] ISO开发了自动化测试方法标准。

This document specifies a method for the determination of the pour point of petroleum products. A separate procedure suitable for the determination of the lower pour point of fuel oils, heavy lubricant base stock, and products containing residual fuel components is also described. The procedure described in this document is not suitable for crude oils. NOTE There is equipment available that uses an automated procedure similar to the one described in this document. However, the precision thereof has not been established[1]. [1] ISO develops an automated test method standard.
