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, 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, 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 ).

This document was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 32, Electrical and electronic components and general system aspects.

This second edition cancels and replaces the first edition (ISO 17447-1:2015), which has been technically revised.

The main changes are as follows:

• Tables 1, 2, 4, 6, 7 include now M9x1;
• Figure A.1 includes now M9.

Introduction

The purpose of this document is to provide a compact and concise specification on glow plugs and their cylinder head housings, which shall replace the existing single standards on each type of glow plugs.

It is intended to specify the main properties, the design requirements and the dimensions of most of the existing types of glow plugs and their cylinder head housings. This should enable the user to work with one comprehensive document valid for most types of glow plugs instead of a number of standards each of them specified for one type only.

This document covers basic characteristics and dimensions for metal-sheath-type glow plugs. ISO 17447-2 covers basic characteristics and dimensions for ceramic-sheath-type glow plugs. Tests and requirements are defined in ISO 17447-3.

1 Scope

This document specifies the main properties and dimensions of metal-sheath-type glow plugs, including the terminals, and the dimensions of their cylinder head housings, for use with diesel (compression ignition) engines.
