International Standard ISO 16889 was prepared by Technical Committee ISO/TC 131, Fluid power systems, Subcommittee SC 6, Contamination control and hydraulic fluids.

ISO 16889-2008《Hydraulic fluid power- Filters- Multi-pass method for evaluating filtration performance of a filter element 》代替ISO 16889-1999， GB/T 18853 修改采用本标准。 为了能够比较过滤器的相关性能，以便选择最合适的过滤器，必须有试验规程。 过滤器的性能特性取决于滤芯 (它的滤材和几何形状)和外壳 (它的结构形状和密封设计)。 实际上，液压油携带污染物连续不断地流经过滤器，直至达到预先设定的极限压降 (旁通阀开启压力或者压差指示器设定的压差)。

In hydraulic fluid power systems, one of the functions of the hydraulic fluid is to separate and lubricate the moving parts of the components. The presence of solid particulate contamination produces wear, resulting in loss of efficiency, reduced …

本标准修改采用ISO国际标准：ISO 16889:2008。 采标中文名称:液压传动过滤器 评定滤芯过滤性能的多次通过方法。
