NATIONAL FOREWORD

This Indian Standard (Part 1) which is identical with ISO 3864-1 : 2011 ‘Graphical symbols — Safety colours and safety signs — Part 1: Design principles for safety signs and safety markings’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Basic Standards Sectional Committee and approval of the Production and General Engineering Division Council.

The standard is issued in four parts and other parts are as below:

Part 2 Design principles for product safety labels

Part 3 Design principles for graphical symbols for use in safety signs

Part 4 Colorimetric and photometric properties of safety sign materials

The text ofISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminology and conventions are however not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
