This Indian Standard (Part 4) which is identical with ISO 80416-4 : 2005 ‘Basic principles for graphical symbols for use on equipment - Part 4: Guidelines for the adaptation of graphical symbols for use on screens and displays (icons)’ issued by the International Organization for Standardization (ISO)was adopted by the Bureau of Indian Standards on recommendation of the Basic Standards Sectional Committee and approval of the Production and General Engineering Division Council.

Other parts in this series are:

The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain 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.
