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).

This document was prepared by Technical Committee ISO/TC 145, Graphical symbols, Subcommittee SC 2, Safety identifications, signs, shapes, symbols, and colours.

This second edition cancels and replaces the first edition (ISO 16069:2004) which has been technically revised.

The main changes compared with the previous edition are as follows:

a) the component luminance requirements of the electrical systems have been updated;
b) the component luminance and dimensions of non-electrical phosphorescent systems have been updated;
c) the document and its requirements have been simplified to improve ease of use and eliminate ambiguity;
d) all example figures which by definition could not cover all arrangements have been removed;
e) an informative annex for designers of non-electrical phosphorescent systems regarding observation distances has been added.
