NATIONAL FOREWORD

This Indian Standard (Part 1) (First Revision) which is identical with IEC 60584-1 : 2013 ‘Thermocouples - Part 1: EMF specifications and tolerances’ issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on recommendation of the Industrial Process Measurement and Control Sectional Committee and approval of the Electrotechnical Division Council.

This Indian Standard replaces the following Indian Standards for thermocouple reference tables: Indian Standard Title

IS 2054 : 1962 Reference tables for nickel/chromium-nickel/aluminium thermocouples

IS 2055 : 1962 Reference tables for platinum rhodium-platinum thermocouples

IS 2056 : 1963 Reference tables for copper-constantan thermocouples

IS 2057 : 1962 Reference table for iron-constantan thermocouples

IS 7988 : 1976 Reference table for chromel-kopel thermocouples

IS 10625 : 1983 Reference tables for nickel/chromium-copper/nickel (chromel-constantan) thermocouples

IS 12051 : 1987 Reference tables for nickel-chromium-silicon/nickel-silicon (Nicrosil/Nisil) Type N thermocouple

The text of 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.
