IS 17064 : Part 3 : 2020/IEC 61810-3 : 2015 Electromechanical Elementary Relays Part 3 Relays with Forcibly Guided ( Mechanically Linked ) Contacts
New Standard from Last Update.
NATIONAL FOREWORD
This Indian Standard (Part 3) which is identical with IEC 61810-3 : 2015 ‘Electromechanical elementary relays — Part 3: Relays with forcibly guided (mechanically linked) contacts’ issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on recommendation of the Power Systems Relays Sectional Committee and approval of the Electrotechnical Division Council.
This Indian Standard is published in several parts. The other parts in this series are:
Part 1 General and safety requirements for UPS
Part 2 Reliability
Part 7 Test and measurement procedures
The text of the IEC Standard has been approved as suitable for publication as an Indian Standard without deviations. 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 a decimal marker, while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
