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.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and expressions related to conformity assessment, as well as information about ISO's adherence to the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html .

This document was prepared by Technical Committee ISO/TC 70, Internal combustion engines, Subcommittee SC 7, Tests for lubricating oil filters.

This second edition cancels and replaces the first edition (ISO 4548-14:2016), which has been technically revised.

The main changes are as follows:

• the title of this document has been updated, removing"cold start simulation";
• the test system schematic has been added;
• the test system setup has been defined in more detail;
• the statistical evaluation in testing with multiple samples has been added.

A list of all parts in the ISO 4548 series can be found on the ISO website.

Introduction

This document establishes standard test procedures for measuring the performance of full-flow lubricating oil filter modules made of composite or temperature-sensitive materials for internal combustion engines. The ISO 4548 series has been prepared in separate parts, each part relating to a particular performance characteristic.

Together the tests provide the information necessary to assess the characteristics of a filter but, if agreed between the purchaser and the manufacturer, the tests can be conducted separately.

1 Scope

This document specifies the hydraulic pulse durability test for composite filter housings. This method tests the ability of full-flow lubricating oil filters manufactured with composite pressure vessel materials for internal combustion engines to withstand an internal pressure surge and cyclic internal pressure variations experienced in the application at specified operating temperatures.

These tests are intended for application to spin-on type filters and detachable filters with disposable elements constructed of composite or temperature-sensitive materials.
