润滑脂的机械杂质测定方法,我国采用SY2721,美国采用FS791B3005.3,日本采用JISK22205.9,以上3个试验方法都是以80倍率以上的生物显微镜来观察10μm以上颗粒的机械杂质,一般测到125μm。方法规定每次取样0.3g。由于该方法取样少,测定结果往往带有一定的局限性。
Grease mechanical impurities measurement method, the use of SY2721 in China, the United States FS791B3005.3, Japan JISK22205.9, the above three test methods are more than 80 times the biological microscope to observe more than 10μm particles of mechanical impurities, the general measured 125 μm. Method provides for each sampling 0.3g. Due to the method of sampling less, the measurement results often have some limitations.
