This standard adopts the following definitions.
3.1 Graphical symbol Graphical symbol An intuitive graphic that can convey information without using language. It can be obtained by drawing, printing or other means. Note: Text symbols that conform to G33101, GB3102 and IEC:27 can be considered as graphic symbols. Approved by the State Administration of Technical Supervision on December 17, 1996 and implemented on May 1, 1997. GB/T 5465.1-1996 3.2 Graphical symbol elements Graphical symbol elements Components of graphic symbols. 1 Graphical symbol elements with specific meanings can be used to represent the same concept when forming a symbol family. 2 Letters, numbers, punctuation marks and mathematical symbols can be used as graphic symbol elements. 3.3 Original symbol (symbol) Original Graphic symbol drawn according to this standard for reference or reproduction. 4 Meaning The meaning specified by each graphic symbol is indicated by its name and supplemented by the scope of application. Its meaning should be clear and has nothing to do with the terms or regulations of the relevant profession. The meaning of a graphic symbol may be related to orientation, but care should be taken to avoid ambiguity (see 8.2). 5 Combination of Graphic Symbols
To express a certain concept, graphic symbols or graphic symbol elements can be combined to form a new graphic symbol. The designated meaning of the new graphic symbol should be coordinated and consistent with the meaning of the individual graphic symbols or graphic symbol elements in the combination. 6 Shape
The shape of the graphic symbol should be
simple, easy to understand and copy;
easily distinguished from other graphic symbols that may be used with it; conveniently associated with its meaning, clear at a glance and easy to understand. For the design of graphic symbols used for safety signs, see GB2894. 7 Design Principles
7.1 Graphic symbols should be designed within the basic graphic pattern (see Chapters 8 and 9 and Figure 3). 7.2 The shape of the graphic symbol should be able to be produced by ordinary technology (such as etching, engraving, printing and photography). 7.3 Generally, the line width of the prototype symbol should be 2mm or 4mm. For the sake of conspicuousness, lines of two widths can be used in combination, as shown in Figure 1.
a) Microphone (basic symbol)
b) On/off (button)
c) Horizontal image displacement (such as TV screen)
Figure 1 Examples of line width and its combination application
7.4 When selecting the minimum spacing between lines, it is necessary to consider the legibility and the reproduction method used. The selection principle is that the minimum spacing between parallel lines should not be less than 1.5 times the minimum line width. 7.5 Do not use angles less than 30°.
7.6 Try not to fill in the graphic symbol.
7.7 When the designed graphic symbol contains arrows, it should comply with the principles of GB1252. 7.8 Use a single word to form graphic symbol elements such as letters, numbers, punctuation marks and mathematical symbols. The font height in the original symbol is at least 10mm.
GB/T 5465.11996
7.9 The use of color is an auxiliary means to indicate the meaning of the graphic symbol, rather than a basic information element. 8 Design procedure
8.1 Procedure
The design of graphic symbols is recommended to be carried out in the following steps: a) Confirm the necessity of the graphic symbol to be designed; b) Clearly state the purpose of the graphic symbol and determine its orientation (see 8.2); c) Analyze application and environmental factors; d) Consider existing or recommended graphic symbols in the same and/or related fields; e) Design the graphic as described in Chapter 9; f) Check whether the graphic symbol is clear, easy to understand, etc.; g) Modify it if necessary.
8.2 Orientation of graphic symbols
The meaning of most graphic symbols does not change with their orientation (see Figure 2a). However, when the meaning of the graphic symbol is related to its orientation, it should be clearly stated [see Figure 2b)].

9.1 Structure
b) Graphic symbol in the form of a line
a) Meaning is independent of position, b) Meaning is related to position Figure 2 Example of graphic symbol orientation
The basic graphics (see Figure 3) should be used as a tool for designing graphic symbols and as the basis for designing prototype symbols (see 9.2) to ensure a balanced visual effect.
9.2 Application of basic graphics
In order to make the graphic symbols have a uniform visual effect of size and make the line thickness of the graphic symbols uniform, the prototype symbol should be placed in the basic graphics according to the following principles:
Graphic symbols composed of a single geometric figure, such as a circle, square or rectangle, should use the corresponding geometric shape of the basic graphics; the lines of the graphic symbol should be designed on the lines of the basic graphics as much as possible; in order to make various graphic symbols have a sense of consistent size, the area of ​​the prototype symbol should be equal, for example, the circle without lines on the outside should be drawn on circle ③ [see Figure 4c], and the circle with lines on the outside should be drawn on circle ④ [see Figure 4d). 9.3 Nominal size, superscript and visible center line 9.3.1 Nominal size
Dimension a is the nominal size, which is equal to 50mm for the prototype symbol. The actual size of the graphic symbol is often different from the nominal size, which is expressed by the proportional factor α, as shown in the following example. Example 1
The actual height and actual width of the original symbol are 28mm and 66.5mm respectively as shown in Figure 5, which can be expressed as follows using the nominal size a5
of the original symbol:
GB/T 5465.1--1996
-Actual height = 0.56a (i.e. 0.56×50mm=28mm)-Actual width--1.33α (1.33×50mm=66.5mm)Q00Q0000e
A square with a side length of 75mm is divided into a grid with an interval of 12.5mm. Each side of the basic square is 50mm long. This--the size is equal to the nominal size of the original symbol. The basic circle with a diameter of 56.6mm has an area roughly equal to that of the basic square ②. The circle with a diameter of 50mm is the inscribed circle of the basic square ②, and each side is 40 mm square, whose four corners are inscribed in the basic circle ③. Two rectangles, each with an area equal to the basic square ②, are perpendicular to each other, and each rectangle symmetrically spans the corresponding side of the basic square ②. The square formed by connecting the midpoints of each side of the square ① constitutes the maximum horizontal and vertical dimensions of the basic figure. The irregular octagon formed by the lines that make an angle of 30° with the four sides of the square ③. The nominal size of the four outermost corners of the basic figure (see 9.3) is a = 50 mm (see 9.3)

Nominal size
If the nominal size α=8mm of the graphic symbol used on the electrical equipment is determined as shown in Figure 5, its actual size is: Actual height=0.56α==0.56×8mm=4.48mm Actual width=1.33a=1.33×8mm=10.64mm Note: In the above example, the height and width of the graphic symbol are defined as important dimensions. However, no matter which dimension of the graphic symbol (height, width, diameter, etc.) is defined as an important dimension, the same rule applies. The nominal size is used as the reference size for photographic reproduction of the graphic symbol. Since the nominal size and actual size of the prototype symbol are related, the proportion of the graphic symbol remains unchanged whether it is enlarged or reduced. 9.3.2 Corner mark
For the convenience of copying and use, the corner mark (see Figure 5) is used as the part of the original symbol. 9.3.3 Visible center line
The four visible center lines mark the visual center point of the graphic symbol at their imaginary intersection. This center point is the reference for designing symbols, which helps to balance the arrangement of several graphic symbol elements or several graphic symbols to obtain a good visual effect. 10 Use of graphic symbols
10.1 Use of original symbols
GB/T5465.1-1996
Graphic symbols can be directly copied or reduced (such as by photography) using the original symbols of GB/T5465.2--1996, but the grid is not allowed to appear.
2 Use of repeated symbols of the same type
In practice, in order to improve the appearance of graphic symbols and make them easier to understand or to coordinate with the design of the equipment used, the following measures can be taken:
Change the line width;
Round the corners,
Fill the graphic symbols.
As long as the basic characteristics of the graphic symbols remain unchanged, their designers can generally deal with the above situations at their own discretion. 10.3 Positioning of graphic symbols
When the meaning of the graphic symbols used is related to their orientation, care should be taken to avoid ambiguity. For example, a graphic symbol marked on a knob will cause ambiguity (see 8.2).
10.4 Size of graphic symbols actually used To ensure the correct identification of the graphic symbols actually used, the minimum value of their nominal size α should be: a
where L is the visual distance.
11 Marking
In GB/T5465.2, the marking composition of each graphic symbol is as follows: a) standard number;
