5 Terminology of graphic symbols
GB/T15566—1995
3 Definitions
Principles and requirements for the use of graphic symbols
The definitions used in this standard shall be in accordance with the provisions of GB/T15565, and the following definitions shall be adopted. 3.1 Apparent size
Subjective feeling of the size of a graphic symbol or a frame of different shapes without considering its actual size. Note that shapes with different geometrical sizes can be perceived by the human eye as the same size. 3.2 Oblique square diamond
A square with diagonals in the horizontal and vertical directions [see Figure 36)]. 4 Design procedure
When designing graphic symbols, the procedures in Chapter 5 of GB/T16900-1997 and the following provisions should be followed: a) Before designing graphic symbols, you should first look for corresponding symbols in GB10001; b) Design specific graphic symbols in accordance with the provisions of the following chapters of this standard; Approved by the State Administration of Technical Supervision on June 27, 1997 and implemented on December 1, 1997
GB/T16903.1-1997
c) Test the comprehensibility of graphic symbols in accordance with the provisions of GB12103. 5 Design
5.1 Basic requirements
Graphic symbols should be eye-catching, clear and easy to understand. 5.1.1 In order to achieve the requirements of eye-catching and clear, the visual design principles of graphic symbols specified in GB/T14543 should be followed. 5.1.2 In order to achieve the requirement of easy understanding, the designed graphic symbols should be tested according to the test procedures specified in GB12103. 5.2 Meaning
5.2.1 The provisions of Article 6.1 of GB/T16900-1997 should be followed. 5.2.2 When specifying the functions of graphic symbols, the graphic symbols should clearly and accurately convey the main application areas and other important information they are intended to express. Definitions of objects that are too narrow or too broad should be avoided. Note: Too narrow definitions of objects are very likely to cause confusion with related or overlapping objects. For example, when different graphic symbols are formulated for canteens, fast food restaurants, and restaurants, too broad definitions of objects often cannot find appropriate graphic expressions. For example, when a graphic symbol that includes ground transportation tools such as "trains, cars, subways" is formulated.
5.3 Negation
5.3.1 The provisions of Article 6.2 of GB/T16900-1997 should be followed. 5.3.2 When the size of a square graphic symbol (see Chapters 6 and 7) St>40mm, the negation bar should be red [see Figure 1a)] and should cover the graphic symbol whose meaning is to be negated. When the size of a square symbol S<40mm or when reproduced in monochrome, the form of the negation bar is shown in Figure 16).
a) Red negation bar for Sr>40mm

b) Negation bar for S<40mm
5.3.3 The negation element that negates only a part of the graphic symbol should be expressed according to Figure 2a). The application example is shown in Figure 2b), and the color should also be red or black (when reproduced in monochrome).

5.3.4 After the addition of the negative elements, if the graphic symbol has a great impact, the graphic symbol can be represented by a mirror image, which can often reduce this impact.
5.3.5 Negation does not mean prohibition. A red circle with a red slash from the upper left to the lower right indicates prohibition (see Chapters 6 and 8). 5.4 Expression and additional elements of symbols
When designing graphic symbols, the graphic symbols to be formulated should be distinguished according to the following situations in order to formulate specific design plans: whether the graphic symbol is to be displayed together with auxiliary signs; a comprehensive explanation of the symbol is given in the form of a legend at an appropriate location in the area where the graphic symbol is used; the graphic symbol needs to be used in combination with a supplementary sign or a text description (for example, indicating fees, distances, some constraints or restrictions, etc.).
5.5 Related objects
If a given object has related objects, these related objects should be considered when formulating the graphic symbol of the object. For example, "swimming", "no swimming", "indoor swimming" and "single aerial pulley", "double aerial pulley" are all related objects. 5.6 Interaction
When designing graphic signs, the results of the interaction between adjacent signs when the signs are used in groups should be considered. 5.7 Apparent size
When designing group signs, attention should be paid to the consistency of the apparent size of the graphic signs (see 7.4.1). 5.8 Reproduction and reduction
The designed graphic symbols should meet the needs of high-multiple reduction. The square graphic symbols or graphic signs should be reduced to S-10mm and their clarity should be maintained. A simplified graphic symbol scheme specifically suitable for high-multiple reduction can be designed. The simplified scheme must still meet the requirements of comprehensibility.
5.9 Arrow
The arrow indicating directional information in the graphic sign should adopt the arrow form of the graphic symbol No. 18 in Table 1 of GB10001-94. The head angle of the arrow is 84°, and the width of each part is equal. The specific width and tail length are determined according to actual conditions. 6 Geometric shape
The geometric shape and meaning of the graphic sign are shown in Table 1. Table 1 Geometric shapes of graphic signs and their meanings Geometric shapes

The inner edge size of the logo border or frame is the graphic symbol size, represented by S (see Figure 3). 7.2 Logo size
The outer edge size of the logo border or frame is the graphic symbol size, represented by S (see Figure 3). 7.3 Relationship between size and viewing distance L
The relationship between the minimum size of graphic symbols and graphic signs of different geometric shapes and the viewing distance L is shown in Table 2. In the same logo system3
The size of each geometric shape should be consistent. GB/T16903.1—1997

Figure 3 Logos of different geometric shapes with equal apparent sizes, as well as symbol and logo sizes 7.4 Size conversion relationship for shape changes
Graphic symbols designed for one shape can also be used for other shapes. 7.4.1 When it is necessary to maintain the same apparent size of graphic logos, the actual size of non-square logos should be larger than the corresponding square logos. When the size of the square, oblique square, circle, and equilateral triangle signs maintain a ratio of 25:25:28:35, the apparent size of each geometric shape is basically the same (see Figure 3).
GB/T16903.1—1997
7.4.2 To ensure the same clarity, the size of the graphic symbol should remain unchanged. In this case, the size of the non-square graphic symbol needs to be increased. In order to minimize this size change, the size exchange ratio between the square, oblique square, circle, and equilateral triangle graphic symbols should be 6:7:8:10.
