Road vehicles -- Aerosol separator performance test for internal combustion engines

ISO/TS 17536-3:2014 defines standardized and repeatable test procedures by using internal combustion engines for the evaluation of blowby oil aerosol separators and specifies engine gravimetric separation efficiency and system pressure tests in both open and closed crankcase ventilation systems. Filter life is not evaluated in this part of ISO 17536. Conformance of a device to legislation is outside of the scope of this part of ISO 17536 and the appropriate regulations are to be consulted.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any

patent rights identified during the development of the document will be in the Introduction and/or on

the ISO list of patent declarations received (see www.iso.org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers

to Trade (TBT), see the following URL: Foreword — Supplementary information.

The committee responsible for this document is ISO/TC 22, Road vehicles, Subcommittee SC 5, Engine

tests.

ISO 17536 consists of the following parts, under the general title Road Vehicles — Aerosol separator

performance test for internal combustion engines:
— Part 1: General

Introduction

Engine crankcase blowby is composed of combustion exhaust gases which have escaped to the

crankcase through piston ring seals and lube oil aerosols generated by thermal and mechanical action

within the engine. These gases are vented from the crankcase to prevent a build-up of high pressure.

The constituents of vented engine blowby gases are recognized as an undesirable contaminant and

technology for their containment is, therefore, evolving.

The device used to separate oil aerosols from the blowby typically releases cleaned gases to atmosphere,

or alternatively returns the cleaned product to the combustion process by feeding into the air inlet,

prior to the turbo compressor. The latter has led to the requirement for a pressure control device to

isolate the engine from turbo inlet suction.

It is the purpose of this part of ISO 17536 to define standardized and repeatable test procedures for

the evaluation of blowby oil aerosol separators and filtering devices using this engine gravimetric test

method. This part of ISO 17536 is only a general guideline for performing an engine test.
