Evaluating particulate contamination of hydraulic fluids-Method of determining the level of contamination (by the gravimetric method) 评估液压油的颗粒污染测定污染程度的方法（通过重量分析法）

发布日期： 1991-12-20

测定液压油样品中固体污染物含量的方法。其原理是在真空条件下通过薄膜过滤器过滤已知体积的样品。过滤器质量的增加代表固体杂质含量。交叉引用:BS 5540:第3部分BS 5540:第5部分ISO 5598

Method whereby the amount of solid contaminant in a sample of hydraulic fluid can be determined. The principle involves filtering a known volume of the sample under vacuum conditions through a membrane filter. The increase in mass of the filter represents the solid impurity content.Cross References:BS 5540:Part 3BS 5540:Part 5ISO 5598
