Methods of test for full-flow lubricating oil filters for internal combustion engines — Part 5: Test for cold start simulation and hydraulic pulse durability
ISO 4548-5:2013 specifies a method of testing the ability of full-flow lubricating oil filters for internal combustion engines to withstand an internal pressure surge such as occurs when an engine is started from cold, and cyclic internal pressure variations experienced during operation. These tests are intended for application to spin-on type filters and detachable filters with disposable elements with a maximum flow rate of 100 l/min.

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. www.iso.org/directives

Introduction
ISO 4548 (all parts) establishes standard test procedures for measuring the performance of full-flow
lubricating oil filters for internal combustion engines. The 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.

INTERNATIONAL STANDARD ISO 4548-5:2013(E)
Methods of test for full-flow lubricating oil filters for
internal combustion engines —
Part 5:
Test for cold start simulation and hydraulic pulse durability
1 Scope
This part of ISO 4548 specifies a method of testing the ability of full-flow lubricating oil filters for
internal combustion engines to withstand an internal pressure surge such as occurs when an engine is
started from cold, and cyclic internal pressure variations experienced during operation.
These tests are intended for application to spin-on type filters and detachable filters with disposable
elements with a maximum flow rate of 100 l/min.
The tests can be applied to other filters, if thought applicable, by agreement between the filter
manufacturer and the purchaser.
NOTE This test is not intended to replace simulated environmental testing (e.g. at very low temperatures). If
such testing is required, it will be the subject of negotiation between the supplier and customer.
