3 Basic principles
Management methods for common and borrowed parts of product drawings and design documents Guidelines for information classification and coding of computer-aided management of mechanical industrial enterprises 3.1 Drawing and document numbers can generally use the following characters: 0~9 Arabic numerals;
A~Z Latin letters (except O and 1);
a short dash, · dot, / slash.
3.2 Basic principles of numbering
a) Scientificity Select the most stable essential attributes or characteristics of things or concepts as the basis and basis for information classification. b) Systematicity Systematize the attributes or characteristics of the selected things and concepts in a certain order and form a reasonable scientific classification system.
c) Uniqueness A code can only uniquely identify a classification object. d) Extensibility: Accommodation categories should be set up to ensure that when new things and concepts are added, the established classification system will not be disrupted. At the same time, conditions should be created for the extension and refinement of the lower-level information management system on the original basis. e) Normative: The abbreviation format of the same level code must be unified. 4 General requirements
4.1 Each product, component, and part drawing and document should have an independent code. Approved by the State Machinery Industry Bureau on March 30, 2000 44
2000-10-01 implementation
JB/T 5054.4—2000
4.1.1 When using a table diagram, each specification of product, component, and part in the table should be marked with an independent code. 4.1.2 When the drawings of the same product, component, or part are drawn on several sheets of paper, each drawing shall be marked with the same code. 4.1.3 When the same CAD file uses more than two storage media, the CAD files in each storage medium should be marked with a service code. 4.1.4 The numbering of common parts should refer to JB/T5054.8 or the provisions of the enterprise standard. 4.1.5 The numbering of borrowed parts should use the code of the borrowed parts. 4.2 The numbering of drawings and documents - generally there are two categories: classification number and genus number. It can also be numbered according to the relevant standards of various industries. 4.3 The numbering of drawings and documents should be coordinated with the requirements of enterprise computer-aided management classification numbering. 5 Classification number
Classification number, according to the similarity of the function and shape of the object (product, component), if the decimal classification method is used for numbering. 5.1 The basic part of the classification number consists of three parts: classification number (large category), characteristic number (middle category) and identification number (small category), separated by a dot or a short horizontal line in the middle, with the dot at the bottom and the short horizontal line in the middle. If necessary, a footnote number can be added at the end. 5.2 The numbering of large, medium and small categories is based on the decimal classification numbering method. The code position of each category is generally composed of 1 to 4 digits (such as level, category, type, and species). Each digit is generally divided into ten gears, such as ten levels (0 to 9), each level is divided into ten categories (0 to 9), each category is divided into ten types (0 to 9), each type is divided into ten kinds (0 to 9), etc.
5.3 The sequence of classification code positions and their meanings are shown in Table 1. Table 1 Classification code position table
Classification number (major category)
Differentiation code position of products, components, parts
Feature number (middle category)

Check number
Code position of product code
1 Classification number can refer to the number specified in JB/T8823. Enterprises have carried out computer-aided management, and should encode the corresponding major category number in the information classification code into the classification number2 The parts in the identification number can also be encoded with a serial number. 3 If necessary, the enterprise code and drawing surface code can be added before the classification number. 5.4 The footnote number indicates the type of product improvement and design document. Generally, the footnote number of the improvement is indicated by Latin letters, and the footnote number of the design document is indicated by the pinyin prefix. Refer to Appendix A (the appendix of the prompt). 5.5 When the product code is automatically generated by a computer, a check number (check code) should be added to the code terminal. The check number should be calculated and determined according to the provisions of GB/T17710.
6 Subordinate number
The subordinate number is numbered according to the subordinate relationship of the product, component, and part. 6.1 The code of the bundle number is composed of the product code and the subordinate number group. It can be separated by a dot or a short dash in the middle, and a footnote number can be added if necessary. 6.2 The code position table of the bundle number is shown in Table 2. When necessary, add the classification number before the first digit to indicate the major category number of the computer-aided management information classification coding system.

Serial number of parts
6.4 The serial number consists of numbers, and its level and number of digits should be determined according to the complexity of the product structure. 6.4.1 The serial number of a part should be numbered within the scope of the product or component to which it belongs. 6.4.2 The serial number of a component should be numbered within the scope of the product or the upper level component to which it belongs. 9
Design documents, product improvement code
6.5 The footnote number is composed of letters, indicating the type of product improvement and design document. If two footnote numbers appear at the same time, the letters used for the two should be distinguished, the improvement footnote number is in front, and the design document footnote number (refer to Appendix A) is in the back, and there is a space between the two, or a short dash, see Figure 1.

Note: Enterprises have carried out computer-aided management, and should compile the corresponding large category number in the information classification code into the classification number. 7.2 Part subordinate number, its code is composed of product code, attribute number and identification number. Its bundle number is the component serial number, see Figure 2, and the level of the component serial number is determined by the enterprise. The identification number is a mixed serial number (serial number) for components (called sub-components) and parts below the first or second level. Three numbering methods are recommended for sub-components and part serial numbers. If necessary, a footnote number may be added to the end, see the provisions of 5.4 of this standard.

7.2.1 Parts and sub-component serial number, it is stipulated that ***—** (such as 001-099) is the sub-component serial number, which is the part serial number. Part serial numbers can also be classified and numbered according to material properties. ** (101~999)
7.2.2 Parts and sub-component serial number, it is stipulated that the integers that are ten (such as 0, 20, 30, ·) are the sub-component serial numbers, and the rest are the part serial numbers.
7.2.3 Parts and sub-component serial numbers are followed by a letter P or Z (such as 1P, 2P, 3P,,) to form the sub-component serial number, and those without letters are part serial numbers.
