标准摘要
[中文适用范围]： 该文件定义了用于评估窜气油雾分离器和过滤装置的标准化和可重复的测试程序，并规定了开放式和封闭式曲轴箱通风系统的实验室分级分离效率。 本文件中未评估过滤器寿命。 该测试的条件部分仅适用于能够满足 ISO/TS 17536-2 中引用的 Dp 稳定性要求的过滤器。 设备与立法的一致性超出了本文件的范围。 由于当前设备的精度有限，本文档不适用于效率高于 99% 的过滤器。 [外文原描述]： This document defines standardized and repeatable test procedures for the evaluation of blowby oil aerosol separators and filtering devices and specifies laboratory fractional separation efficiency in both open and closed crankcase ventilation systems. Filter life is not evaluated in this document. The conditioned portion of this test only applies to filters that can meet the Dp stability requirements referenced in ISO/TS 17536-2. Conformance of a device to legislation is outside of the scope of this document. Due to limited precision using current equipment, this document is not suitable for filters above an efficiency of 99 %.
