IS 7722 : 2024/IEC 60382 : 1991 Analogue Pneumatic Signals for Process Control Systems
NATIONAL FOREWORD
This Indian Standard (First Revision) which is identical to IEC 60382 : 1991 'Analogue pneumatic signal for process control systems' issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on the recommendation of the Industrial Process Measurement and Control Sectional Committee and approval of the Electrotechnical Division Council.
This standard was originally published in 1975. This revision has been undertaken to harmonize it with the latest developments that have taken place at international level.
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'; and
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.
