ISO/TS 17536-2定义了评估窜气油气溶胶分离器和过滤装置的标准化和可重复的试验程序，并规定了开放式和封闭式曲轴箱通风系统中的实验室重力分离效率和系统压力试验。ISO/TS 17536-2对气溶胶重量分析效率的限制为0%至99%。 注意重量分析效率>；由于测试持续时间长和绝对过滤器重量测量，99%可能难以测量。 ISO/TS 17536-2中未评估过滤器寿命。 本试验方法仅适用于具有可连接至试验设备的规定管状入口、出口和排水管的装置。 对于缺少此类连接的装置，例如，内置在阀盖中的装置，请参见附录a。

ISO/TS 17536-2 defines standardized and repeatable test procedures for the evaluation of blowby oil aerosol separators and filtering devices and specifies laboratory gravimetric separation efficiency and system pressure tests in both open and closed crankcase ventilation systems. ISO/TS 17536-2 has a limitation of 0 % to 99 % for aerosol gravimetric efficiency. NOTE Gravimetric efficiencies >99 % may be difficult to measure due to long test durations and absolute filter weight measurements. Filter life is not evaluated in ISO/TS 17536-2. This test method only applies to devices that have a defined tubular inlet, outlet and drain that can be connected to the test equipment. For devices that lack such connections, for example, one that is built into a valve cover, see Annex A.
