The design process of graphic symbols shall comply with the provisions of [690] and follow the following design procedures Process flow a) Confirm that the graphic symbol to be designed is not a safety sign or a non-sign graphic symbol; b) Clarify the object and meaning to be expressed by the graphic symbol to be designed; Analyze the expected use environment and characteristics of the user population of the graphic symbol; d) Confirm that there is no graphic symbol with the same meaning as the graphic symbol to be designed in the current (GB/T10001 (all parts) and other relevant national standards:
Assign meaning to the graphic symbol to be designed, and give a description of its function and application place: Search for symbol elements that may be used to express related meanings, symbol elements in graphic symbols, and graphic symbols that can be used as f
elements in existing standards, and These symbol elements are combined to form a new graphic symbol; 8) If the graphic symbol cannot be formed by directly using or combining the existing symbol elements, the design template specified in Chapter 6 is used and the graphic design requirements specified in Chapter 7 are followed to design the graphic symbol: 1

GB/T16903—2021
h) Test the graphic symbols in accordance with GB/T16900.2 and GB/T16903.3 to evaluate the comprehensibility and perceptibility of the graphic symbols in the use environment:
Determine the graphic symbol and make fine adjustments to the graphic symbol to achieve visual beauty and coordinated composition. 5. Assign meaning and function to graphic symbols and clarify the application site 5.1
A graphic symbol should only be used to convey a public message and belong to one of the following categories: a)
General:
Tourism and leisure:
Passenger and freight transport;
Sports and fitness;
Shopping;
Health care:
Office and teaching:
Behavioral instructions;
Barrier-free facilities.
The meaning of the graphic symbol should be given according to the function to be represented by the graphic symbol to be designed and its application site. The meaning should convey information accurately, concisely and conveniently.
5.3 After the design of graphic symbols is completed, the meaning and description of the graphic symbols should be given in words. The function and application place of the graphic symbols should be clearly stated in the description (see Figure 1):
[Source: GB/F10001.3-2021(24. Car washing Meaning: car washing.
Description: Indicates the car washing function, and is used in places where car washing services are provided, such as washing rooms. Figure 1 Example of the meaning and description of graphic symbols Design template

6.1.2 When designing graphic symbols in the template, the graphic of the symbol should not exceed the square area formed by the 90.0mm reference line. It should not be smaller than the square area formed by the 75mm reference line. In general, the graphic of the symbol should not be smaller than the square area formed by the 77.5mm reference line
6.1.3 When designing graphic symbols in the template, the edges or ends of different graphics should coincide with the reference lines given in Table 1. Table 1. Reference lines that are recommended to coincide with the edges or ends of different graphics in graphic symbols. Edges or ends of graphics

Recommended reference lines to overlap
6.2.1 Human figure elements in graphic symbols should use human figure templates. The front human figure should use the human figure template presented in Figure 3, and the side human figure should use the human figure template presented in Figure 4.
6.2.2 The center points of limb movement and rotation of limbs given in the template should be used to design the human figure into an ideal posture. 6.2.3 When the human figure forms a graphic symbol with other symbol elements, the designer should first complete the human figure design according to the human figure template, and then reduce the human figure in proportion, cut it or cut it and put it in the human figure to combine it with other symbol elements as needed.

7 Graphic design
General principles
Graphic design of graphic symbols:
Make the selection of symbol elements related to their intended meaning; Include symbol details that help understand the meaning of graphic symbols; Make the newly designed graphic symbols easy to distinguish from other graphic symbols: Design based on objects, actions or a combination of them that are easily recognizable to the public. Avoid using graphics related to popular styles as symbol elements;
Keep the style of graphic symbols in the same field consistent: Make the overall length and width ratio of the graphic less than 3:1; Consider the impact of adding negative elements (negative slashes) on the comprehensibility of graphic symbols: It is composed of concrete forms.
Use of characters
Ningmu, numerals, punctuation marks, mathematical symbols and other symbols should only be used as symbol elements. If some letters or punctuation marks have been widely recognized, they can be used alone as graphic symbols, such as the letter "P" for parking and the punctuation mark "" for asking questions.6
