Indian Standard GRAPHICAL SYMBOLS
USED IN ELECTROTECHNOLOGY PART XV AIRCRAFT ELECTRICAL SYMBOLS
0. FOREWORD
0.1 This Indian Standard (Part XV) was adopted by the Indian Standards Institution on 23 January 1976, after the draft finalized by the Electro- technical Standards Sectional Committee in consultation with the Air- craft Electrical Equipment ‘Sectional Committee had been approved by the Electrotechnical Division Council.
0.2 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 easy to under- stand and universal in meaning, it has become necessary to standardize the basic symbols for various devices commonly used in the field of electrical engineering.
0.3 In the preparation of this standard assistance has been derived from IEC Pub 117-6 Recommended graphical symbols Part 6 : Aircraft miscel- laneous symbols issued by the International Electrotechnical Commission.
0.4 This standard is one of a series of Indian Standards on graphical symbols used in electrotechnology. A list of Indian Standards so far published in this series is given on P 26.
1. SCOPE
1.1 This standard (Part XV) covers graphical symbols for use in aircraft electrical systems.
2. GENERAL
2.1 Single-line representations are included for some symbols, and the same principles may be adopted for others, for use in diagrams which are intended to show the general layout of an electric circuit and its main component parts.
2.2 Orientation, relative dimensions, and points of attachment of conductors to a symbol .are optional.
3
Is t 2832 (Part XVI - 1976
2.3 The symbol for a terminal may be added at each point of attachment of conductors to a symbol, but it should not be considered as part of the symbol except where shown in the following groups of symbols.
2.4 For switch contacts, the circle and triang!e symbols are each used to indicate a specific duty, namely, the circle for ‘locked-on’ contacts and the triangle for contacts from which there is automatic spring return on release of the operating force, whether manual or magnetic.
2.5 Where alternative symbols are shown for a basic component either symbols may be used for the derived symbols but identical representation should be used on any one diagram or associated set of diagrams
