Methods of test for full-flow lubricating oil filters for internal combustion engines — Part 6: Static burst pressure test
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 and to determine their burst pressure and the failure mode concerned. It does not apply to filters for use in aeronautical applications or plastic components.

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 third edition cancels and replaces the second edition (ISO 4548-6:2012), which has been technically
revised. The main changes in the third edition are as follows:
— The verification that filters meet technical requirements and the determination of the filter failing
pressure have been separated into 6.1 and 6.2, respectively.
— The first pressure increment in the verification has been specified with a known value.
— Each incremental pressure has been changed to the smaller value for more accurate determination.
A list of all parts in the ISO 4548 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A
