IEC Foreword
1) IEC (International Electrotechnical Commission) is a worldwide standardization organization including all national electrotechnical committees (IEC national committees). The stated objective of the IEC is to promote international cooperation on all matters relating to standards in the electrical and electronic fields. For this purpose and as required by other activities, the IEC also publishes International Standards. The preparation of International Standards is entrusted to technical committees. Any IEC National Committee may participate in the standard-making process if it is interested in the subject under study. International organizations, governmental and non-governmental organizations that have relations with the IEC may also participate in the standard-making process. The IEC and the International Organization for Standardization (ISO) work closely under the conditions determined by an agreement with ISO. 2) The formal decisions and agreements of the IEC on technical matters are drawn up by technical committees in which national committees with special interest in these matters participate, and express as far as possible an international consensus on the subject matter involved. 3) They are accepted by the National Committees in the sense that they are published in the form of standards, technical reports or guidelines and recommended for international use.
4) In order to promote international unification, the IEC National Committees undertake the task of applying the IEC International Standards to the greatest extent possible in their countries and regions. Any differences between IEC International Standards and the corresponding national or regional standards should be clearly indicated in the latter. International Standard IEC 617-8 was prepared by IEC Technical Committee 3A (Graphical Symbols for Diagrams) of IEC Technical Committee 3 (Documentation and Graphical Symbols).
This second edition repeals and replaces the first edition of 1983 and is technically revised. The text of this standard is based on the following documents:
Draft International Standard (FDIS)
3A/386/FDIS

The specifications and referenced standards of this series can be found in IEC60617-1. The above symbols are designed according to the requirements of ISO11714-1 to be published. The module M used is 2.5 mm. In order to make the smaller symbols clearer, these symbols are enlarged by - times in this standard and marked with "200%" in the symbol column; in order to save space, the larger symbols are reduced by times 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 a uniform 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 old symbols included in Annex A of the first edition of IEC 617-8 have a transition period. This part is no longer included in the second edition, and it will be made clear that they are no longer used.
The index of Annexes B and C 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 of 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). 164

Text symbol or multiple or approximate divisor of the unit of the quantity being measured (see 08-02-01 and 08-02-07 for examples); Text symbol of the quantity being measured (see 08-02-05 and 08-02-06 for examples); Chemical formula (see 08-02-13 for examples); Graphic symbol (see 08-02-08 for examples). These symbols or formulas shall be based on the relevant information displayed by the instrument, regardless of the method of obtaining the information. 1.2 The text symbols for the quantity being measured and the unit shall be selected from IEC 60027: "Text symbols for use in electrotechnical engineering"; if the text symbols for IEC 60027 or chemical elements are not applicable, other text symbols may be used, but this shall be stated in the diagram or reference document.
1.3 When using text symbols for the units of the measured quantity, it may be necessary to display the text symbol for the quantity as auxiliary information and indicate it below the text symbol (see 08-02-02 for examples).
Auxiliary information concerning the quantity being measured and any necessary qualifiers may be indicated below the text symbol for the quantity 1.4 If the instrument indicates or records one or more quantities, the outlines of these appropriate symbols must be arranged horizontally or vertically (see 08-03-02 and 08-04-14 for examples).
