Scope

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 %.
