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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use
of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of this document, ISO had not received
notice of (a) patent(s) which may be required to implement this document. However, implementers are
cautioned that this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents. ISO shall not be held responsible for identifying any or all
such patent rights.

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 4548-13:2013), which has been
technically revised.
The main changes are as follows:
— temperature range reduced to more applicable values;
— each incremental pressure changed to the smaller value for more accurate determination;
— Weibull analysis included for getting the statistical data with multiple test samples.
A list of all parts in the ISO 4548 series can be found on the ISO website.

Introduction
The ISO 4548 series establishes standard test procedures for measuring the performance of full-flow
lubricating oil filters for internal combustion engines. Each part in the series relates 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 may be conducted separately.
This document deals with filter modules made of composite materials for internal combustion engines
in terms of static burst pressure.

Part 13:
Static burst pressure test for composite filter housings
1 Scope
This document specifies a method of testing full-flow lubricating oil filters for internal combustion
engines to determine their ability to withstand a static pressure objective at high and low temperatures
and to determine their burst pressure and the failure mode.
It applies to all oil fi
