NATIONAL FOREWORD

This draft Indian Standard which is identical to IEC 60617 : 2024 database ‘Graphical symbols for diagrams’ issued by the International Electrotechnical Commission (IEC) was be adopted by the Bureau of Indian Standards on the recommendation of the Basic Electrotechnical Standards and Power Quality Sectional Committee and approval of the Electrotechnical Division Council.

It is common in electrical engineering practice to employ graphical symbols to denote the various means and devices used when making diagrams of connections. With the object of making these diagrams easily understandable and universal in meaning, it became necessary to standardize the basic symbols for various devices which are commonly used in the field of electrical engineering. Consequently, work on standardization of graphical symbols for diagrams in the field electrotechnology began around the year 1960 and since then several standards have been brought out covering symbols applicable to specific areas in the field. Over the years, some of these have also undergone significant updating to keep pace with additional needs and developments at the international level.
