标准摘要
[中文适用范围]： 本文件规定了确定液压系统所需清洁度等级的方法，即根据运行液压系统的具体要求确定最合适的流体清洁度等级。 它适用于按照 ISO 4406 表示流体清洁度级别的系统，但也可以转换为其他污染编码系统。 它既适用于高低压流体动力系统，也适用于润滑系统。 它不包括液压油热分解产生的软可变形颗粒的影响。 [外文原描述]： ISO 12669 specifies a method of determining the required cleanliness level of a hydraulic system, that is, the most appropriate fluid cleanliness level for an operating hydraulic system based upon the individual requirements of that system. It is applicable to systems where the level of fluid cleanliness is expressed in accordance with ISO 4406, although conversion to other contamination coding systems is possible. It is applicable to both high and low pressure fluid power systems and also lubrication systems. It does not include the effects of soft deformable particles that can be generated by thermal decomposition of the hydraulic fluid.
