摘要
介绍了制定等同于英国标准IP 346-1996"未使用润滑油基础油及无沥青质石油馏分中稠环芳烃测定———二甲基亚砜折光指数法"测定方法的实验室建立过程。通过验证,所建立的试验方法重复性和再现性满足IP346方法精度的要求,该方法的建立为国内润滑油的研究开发和方法标准的完善提供了一种新的检测手段,并为国内润滑油研究与世界同步提供支持。
The establishment of the test method equaled to British Standard IP 346 - 1996： Petroleum and its products - determination of polycyclic aromatic in unused lubricating base oils and asphaltene free petroleum fractions - dimethyl sulphoxide extraction refractive index method was introduced in detail. The test results showed that the repeatability and reproducibility of this method can meet the precision requirements of IP 346 - 1996. This method provides a new inspecting means for the domestic R＆D of lubricating oil and the upgrade of test method, and a support to keep pace with international level.
