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 ).

This fifth edition cancels and replaces the fourth edition (ISO 105-A03:1993), which has been technically revised. It also incorporates the Technical Corrigenda ISO 105-A03:1993/Cor.1:1997 and ISO 105-A03:1993/Cor.2:2005. The main changes compared to the previous edition are as follows:

• the use of grey and black sleeves has been allowed;
• a tolerance of ±2 for the Y tristimulus value has been introduced.

A list of all parts in the ISO 105 series can be found on the ISO website.
