Methods of test for full-flow lubricating oil filters for internal combustion engines — Part 15: Vibration fatigue test for composite filter housings

ISO 4548-15:2014 specifies a method of testing the structural integrity of full-flow lubricating oil filters to withstand engine vibrations. This test is intended for application to spin-on type filters and detachable filters with disposable elements with a maximum flow rate of 100 L/min. Upon agreement between manufacturer and purchaser, this test method can be applied to filters with higher flow rates. This test method is intended for test parts made from composite materials that experience mechanical property changes within the temperature range experienced in service. The test can be applied to filters with other temperature sensitive materials if thought applicable by agreement between the filter manufacturer and the purchaser.

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).
