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

Introduction
A stop and start system requires more frequent engine starting therefore, the starter relay used in
such an engine should be durable. Currently, there is no common durability test method for starter
relays, and most individual durability test methods of vehicle manufacturers and relay suppliers use
actual starter solenoids as electrical loads of the relay. However, heat mass of the starter solenoid is
not sufficient, so cooling equipment and/or a longer test cycle time are necessary to prevent starter
solenoid damage.
This document provides a test method using a simulated electrical load which can shorten the test
period or eliminate cooling equipment.
