Compared with the original standard, it has made major changes. The main changes are as follows: 1. Added three chapters: "Classification of Graphical Symbols", "Design Procedure" and "Registration" - Chapter 6 added two chapters: "Negation" and "Design Method", and made appropriate changes and adjustments to other contents of the original standard. - Article 4.3.1 of the original standard is not very operational, so this revision will remove it. This standard will be implemented from December 1, 1997. This standard is proposed by the China Institute of Standardization and Information Classification and Coding. This standard is under the jurisdiction of the National Technical Committee for Graphic Symbols This standard is drafted by the China Institute of Standardization and Information Classification and Coding, the National Technical Committee for Technical Drawing Standardization, the Standard and Quota Department of the Ministry of Construction, and the National Technical Committee for Electrical Documentation and Graphic Symbols Standardization. The main drafters of this standard are Bai Dianyi, Chen Yuanqiao, Zhang Liang, Qiang Yi, Wei Ming, and Guo Ting. The original standard was issued in 1986 and revised for the first time in 1997. 1 Scope

3 Definitions
The definitions used in this standard are in accordance with the provisions of CB/T15565. 4 Classification of graphic symbols
Graphic symbols can be divided into three categories according to their application fields: technical documents, equipment and signs. 4.1 Graphic symbols for technical documents, mainly including: simple diagrams Symbols: Indicate the relationship between the components of a system or equipment in a simple diagram. Symbols for marking: Indicate the geometric characteristics (such as size, distance, angle, shape, instrumentation, spacing, microscopic surface, etc.) and manufacturing processes involved in the entire process of product design, manufacturing, measurement and quality assurance. 4.2 Graphic symbols for equipment, mainly include: Display symbols: Display the function of the equipment (such as: connection terminals, filling points, etc.) or working status (such as: open, close, through, off, etc.); Control symbols: Serves as control or operation instructions for equipment. 4.3 Graphic symbols for signs, mainly include: Symbols for public information signs: Provide information that the public can understand without professional or vocational training. Symbols for safety signs: Convey specific safety information. Symbols for traffic signs: Convey specific traffic management information. Symbols for packaging, storage and transportation: used on the outer packaging of goods to indicate information related to transportation: Note: Symbols used to indicate the contents of the package are graphic symbols for equipment: Approved by the State Bureau of Technical Supervision on June 27, 1997, and implemented on December 1, 1997
5 Design procedure
The following procedures should be followed when designing graphic symbols: CB/T 16900-1997
) Prove that there is an objective need to use graphic symbols to convey information: 1) Collect the necessary information for the design and standardization of graphic symbols; c) Clearly and unambiguously summarize the objects represented by the graphic symbols and their orientation factors; d) Analyze environmental and application factors;
e) Find existing graphic symbols in the same or related fields; f) Design the shape of the graphic symbol in accordance with (GB/T16901.1.GB/T16902.1GB/T16903.1); g) Test the clarity and comprehensibility of the graphic symbols; h) Modify the final version.
6 Design
6.1 Meaningwww.bzxz.net
6.1.1 The meaning of a graphic symbol is described by its name and application instructions. The meaning of a graphic symbol should be clear and its name should be universal. 6.1.2 A meaning can only be expressed by a graphic symbol. Different names should be given to different forms of graphic symbols designed for different purposes or designed for different views. 6.1.3 It should be avoided as much as possible that the same graphic symbol represents different meanings. If it cannot be avoided, a graphic symbol used in a certain field can represent another meaning in other fields without causing misunderstanding. 6.1.4 The meaning of some graphic symbols depends on their direction. In this case, care should be taken to avoid confusion of meaning after the direction is changed. 6.2 Definition
Negation should be formed by attaching the negative element to the graphic symbol. The negative element is represented by a negative straight bar (a slash from the upper left to the lower right) or a shape composed of two straight bars tilted at an appropriate angle. If a message can be conveyed in both positive and negative forms, the former should be used. Graphic symbols combined with negative elements should be expressed in positive form. When using negative elements, care should be taken that the negative elements do not interfere with the clarity and comprehensibility of the graphic symbols. 6.3 Combination
Use the standardized function derivatives and (or) graphic symbol elements to combine into new graphic symbols as much as possible. The meaning of the newly combined graphic symbols should be coordinated with the meanings represented by their components: 6.4 Configuration
The configuration of graphic symbols should achieve:
Clear and simple: the graphic symbols have few details and are easy to see and distinguish: easy to distinguish from other surrounding symbols that may be used at the same time, easy to understand and remember: easy to associate with the meaning to be expressed, that is, easy to understand or learn and remember. Easy to draw and easy to make: easy to draw by hand, can be produced by common production methods, and meet the requirements of microfilming and computer processing
7 Registration
Graphic symbols of national standards should be uniformly registered. Any graphic symbol can only have one registration code. The registration code system consists of the following: a) national standard number;
b) the number of the graphic symbol in the standard;
c) the registration number of the graphic symbol.
