This standard is equivalent to the International Electrotechnical Commission standard IEC60617-11: 1996 "Graphical symbols for schematic diagrams Part 11: Architectural and surveying installation drawings and schematic diagrams".
This standard is a revision of GB/T4728.11-1985 "Graphical symbols for electrical diagrams - electric lighting and telecommunications layout". Compared with GB/T4728.11-1985, this standard adds Chapter 17 "Trunk systems", Part 5 "Open-air equipment", Chapter 18 "Airfield navigation lights and indicators" with a total of 57 symbols, and deletes 163 symbols of GB/T4728.11-1985. GB/T4728.11 is a part of the series standard "Graphic symbols for electrical schematic diagrams". This series of standards includes the following parts:
GB/T4728.1 Graphical symbols for electrical diagrams

The original IEC60617-11:1996 Appendix A and Appendix B are French and English indexes respectively, which are deleted in this standard. Appendix B of this standard is the symbols added in GB/T4728.11-1985 that are not in the original IEC60617-11 (1st edition). This standard replaces GB/T4728.11-1985 from the date of implementation. Appendix A of this series of standards are all symbols that existed in the first edition of IEC60617 and were adopted in the first edition of GB/T4728, but are now cancelled. Since GB/T4728.11-1985 does not have such symbols, in order to unify with this series of standards, this standard does not have Appendix A. Appendix B of this standard is a suggestive appendix.
This standard was proposed and coordinated by the National Technical Committee for the Preparation of Electrical Documents and the Promotion of Graphical Symbols. This standard was drafted by the Mechanical Science Research Institute. The main drafters of this standard are: Guo Ting, Li Shilin, Gao Huimin, Li Ping, Wei Yanyun, Zhang Ying. 245

IEC Foreword
1) IEC (International Electrotechnical Commission) is a worldwide standardization organization including all national electrotechnical committees (IEC National Committees). The stated goal of IEC is to promote international cooperation on various issues related to standards in the electrical and electronic fields. For this purpose and other activities, IEC also publishes international standards. The formulation of international standards is entrusted to technical committees. Any IEC National Committee may participate in the standard formulation work if it is interested in the subject being studied. International organizations, governments and non-governmental organizations that have relations with IEC may also participate in the standard formulation work. IEC and ISO work closely under the conditions determined by the agreement between them. 2) IEC formal resolutions and agreements on technical issues, developed by technical committees with the participation of national committees that are particularly concerned with these issues, express international consensus on the subject matter as far as possible. 3) They are published in the form of standards, technical reports or guidelines and recommended for international use, and in this sense are accepted by the national committees.
4) In order to promote international unification, the IEC national committees undertake the task of applying IEC international standards to the greatest extent possible in their countries and regions. Any differences between IEC international standards and corresponding national or regional standards should be clearly indicated in the latter. International Standard IEC60617-11 was drafted by 3A Technical Committee (Graphic Symbols for Diagrams) of IEC Technical Committee 3 (Documentation and Graphic Symbols).
This second edition abolishes and replaces the first edition of 1983 and has been technically revised. The text of this standard is based on the following documents:
Draft International Standard (FDIS)

The scope and referenced standards of this series are shown in IEC60617-1. The above symbols are designed according to the requirements of ISO11714-1\ to be published. The module M=2.5mm is used. In order to make the smaller symbols clearer, these symbols are enlarged by one time in this standard and marked with "200%" in the symbol column; in order to save space, the larger symbols are reduced by one time and marked with "50%" in the symbol column. In order to facilitate the drawing of multiple terminals and to meet other layout requirements, the size of the symbol (such as height) may be changed in accordance with clause 7 of ISO 11714-1. Regardless of whether the size of the symbol is enlarged, reduced or corrected, the original line width is not corrected proportionally.
The symbols of this standard should be arranged so that the distance between the connecting lines is a multiple of a certain module. In order to facilitate the marking of the terminal, 2M is usually selected. For ease of understanding, the symbols are drawn at a certain size and the same grid is used when drawing all symbols. In computer-aided drawing systems, all symbols should be drawn within a grid, and the grid used is reproduced on the background of the symbol. The index of Annexes A and B includes an alphabetical index of the symbol name and its number, and the symbol name is based on the description of the symbol in this part. The general index including the alphabetical order of the symbols of all parts is given by IEC 60617-1. * Currently, it is still in the draft international standard stage (Document 3/563/DIS). 247

The graphic symbols listed in this standard are suitable for drawing small-scale maps or plan views. The graphic symbols listed in other parts of the GB/T4728 series of standards are not suitable for drawing such maps, but they can still be used when drawing such maps. On the map, the center of the graphic symbols listed in Parts 1, 2 and 5 should correspond to the exact position of the center of the physical object. Part 1 Power Stations and Substations
