NATIONAL FOREWORD

This Indian Standard (Part 1) (Second Revision) which is identical with IEC 60950-1 : 2005 ‘Information technology equipment - Safety - Part 1: General requirements’ issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on the recommendation of the Computer Hardware, Peripherals and Identification Cards Sectional Committee and approval of the Electronics and Information Technology Division Council.

This standard was originally published in 1992 and was identical to IEC 950 : 1986. The standard was revised in 2003 based on ISO/IEC 60950-1 : 2001. This standard is now again being revised to align it with the latest IEC Publication IEC 60950-1 : 2005.

The text of IEC 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 in the International Standard while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
