New Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard which is identical with IEC 62640 : 2015 ‘Residual current devices with or without overcurrent protection for socket-outlets for household and similar uses’ issued by the International Electrotechnical Commission (IEC)was adopted by the Bureau of Indian Standards on recommendation of the Low Voltage Switchgear and Controlgear Sectional Committee and approval of the Electrotechnical Division Council.

The text of the IEC Standard has been approved as suitable for publication as an Indian Standard without deviation. Certain terminologies 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 the decimal marker, while in Indian Standards, the current practice is to use a point (.) as a decimal marker.
