This standard applies to the preparation of national standards, national military standards, professional standards (ministerial standards) and ministerial guiding technical documents for technical standards in the electronics industry. The preparation of enterprise standards in the electronics industry should refer to this. 2 General requirements for drafting standards
When drafting a standard, the following requirements should be met in principle: 2.1 GB1.1 Basic provisions for drafting standards in standardization work guidelines; 2.2 GB1.3 Provisions for drafting product standards in standardization work guidelines: GB1.2 Provisions for publishing and printing of standards in standardization work guidelines; 2.3
GB3860 Document subject indexing rules;
GJB0.1 Provisions for publishing and printing of national military standards; 2.5
2.6 Electronic component certification standards should be compiled in accordance with the relevant compilation requirements for certification standards, including the National Bureau of Standards document Guobiaofa (1984) No. 274 "Notice on Issuing Interim Provisions on National Certification Standards" and the Ministry of Electronics Industry Standardization Research Institute document (1985) No. 163 "Notice on the Preparation of Detailed Specifications for Electronic Components for Quality Certification" Regulations on the Implementation of the Format of the First Page of Standards [For specific format examples, see Appendix A and B (Supplement)]: 2.7 National Bureau of Standards Document No. 508 (1984) "Notice on the Adoption of Legal Measurement Units in National Standards"; 2.8 National Bureau of Standards Document No. 133 (1984) "Notice on the Issuance of the "Management Measures for the Adoption of International Standards"";
2.9 Implement other relevant national, national military, and professional (departmental) basic standards, such as: sampling, reliability, environmental testing, priority numbers and priority number systems, measurement units, text symbols, graphic symbols, electrical drawing, mechanical drawing, tolerance and fit, geometric tolerance, electromagnetic compatibility, safety and other standards; 2.10 The application for approval of national standards, professional (departmental) standards and departmental guidance technical documents is required to be a typed manuscript or a neatly written handwritten manuscript, and the application for approval of national military standards is required to be a neatly written handwritten manuscript. The paper used for handwritten manuscripts is always grid manuscript paper. 3 Basic requirements for drafting standards
3.1 Implement national laws, regulations and policies and coordinate with relevant standards Approved by the Ministry of Electronics Industry of the People's Republic of China on October 1, 1981 and implemented on January 1, 1988
National laws and regulations are the concrete embodiment of national policies, so all relevant laws, regulations and policies promulgated by the state should be implemented.
Standards are a systematic document, and there are extensive connections between various standards. Relevant standards should be coordinated and complement each other to give full play to the role of standardization and achieve the expected economic benefits. Lower-level standards shall not conflict with higher-level standards.
3.2 Content expression should be accurate and concise
Once a standard is issued, all relevant units must implement it. The standard provisions should be accurate and concise to facilitate correct understanding and smooth implementation.
Standards should be logical, simple and clear, with a clear tone and avoid ambiguous words. Similar sentence patterns should use the same structure to prevent different people from having different understandings from different perspectives. When writing standards, attention should be paid to highlighting the theme, and the content that does not belong to the scope of the standard should not be praised at all. The standard only stipulates what "should" be done, what requirements "must" be met, and what "must not" be done, etc. When writing the content of the standard, it is appropriate to use words when it is appropriate to use words, and use charts when it is appropriate to use charts. 3.3 Technical content should be correct
The technical indicators, parameters, formulas and other technical contents specified in the standard do not explain the source or derivation process, so the technical content must be correct. The determination of important contents (principles, methods, indicators, etc.) must have sufficient basis, and those that need to be verified must be verified by experiments, and attention should be paid to making full use of the data and materials obtained in scientific research and production. 3.4 The terms, symbols and codes used should be unified. The terms, symbols and codes used in the same standard should be unified before and after, and should also be unified with other relevant standards. All those that have been stipulated in the national and professional (departmental) terminology standards should be quoted or adopted by other relevant standards when they are written. When writing the draft standard, these existing terminology standards should be carefully consulted. 3.5 Format and details
From the drafting stage of the standard, the draft standard must be written in strict accordance with the relevant provisions of GB1.1 and GB1.3 on the composition, content arrangement, hierarchical division, numbering and writing details of the standard. 4 Matters to be noted when writing the draft standard
4.1 Name of the standard
The name of the standard should be as short as possible, which can clearly define the subject of the standard and distinguish it from other standards. When several independent parts in a series of standards are published with the same standard serial number, the standard should have a general name, and each independent part should be named separately. The two names should be written in two lines on the cover and the first page. When describing in the standard clause, there should be a space between the two.
When determining the name of the standard, it should be considered to expand the scope of application of the standard as much as possible. 4.2 English name of the standard
The English name should be marked below the Chinese name of the standard on the cover and the first page of the national standard and the national military standard. If international or foreign advanced standards (texts from English-speaking countries) are adopted, the English names of international and foreign standards shall be copied.
If foreign advanced standards from non-English-speaking countries or national standards and national military standards formulated by my country are adopted, the English names shall be copied or translated into English with attention to the language characteristics and idioms of English, and shall be handled in accordance with the idioms of international standards of relevant professions.
For example, general technical conditions, general technical conditions, general specificationsGeneric specification
Generictechnical specificationGeneric technical condition
For example: technical requirements
Performance requirements
Technical demand
Technical reguirements
(correct)
(incorrect)

The first letter of the sentence in the English name shall be capitalized, and the rest shall be lowercase. However, no matter where the proper noun is located, the first letter must be capitalized. 4.3 Provisions on filling in the standard classification number of national standards The standard classification number shall be filled in by the standard sponsor below the "UDC" in the upper left corner of the cover of the draft national standard (draft for approval).
The standard classification number shall be filled in according to the secondary category classification number specified in the "China Standard Document Classification (Trial)". The commonly used secondary category classification numbers of electronic industry technical standards are shown in Appendix C (Supplement). 4.4 Introduction
The introduction is generally not titled or numbered. Its content includes 4.4.1 and 4.4.2, or it can be part of them. If these contents do not need to be explained, the introduction can be omitted. 4.4.1 The degree of adoption of international standards
Standards written using international standards should state the degree of adoption in the introduction, and state the number and name of the international standard. For example: This standard is equivalent to (or equivalent to, references) the international standard IEC××××-×××× (standard name)".
When foreign advanced standards are adopted, no explanation is given in the introduction. 4.4.2 Others
Other contents that need to be expressed in the introduction. Such as supplementary explanation of the standard name, etc. 4.5 Subject content of the standard
The subject content of the standard must be briefly stated in the "Subject content and scope of application" chapter. The following typical sentences are recommended:
This standard gives the ×××× rules (or terms and their definitions, symbols, codes, etc.) This standard stipulates the ×××× classification (or technical requirements, test methods, inspection rules, packaging requirements, etc.). 4.6 Terms in the standard
Should try to use standard terms or unified terms in this profession, and should not use common names or colloquialisms. The provisions on the unified writing of several terms in the national military standards for electronic components are in Appendix D (Supplement). ·3
4.7 Principles to be considered when determining the technical requirements in the standard When selecting and determining the technical requirements of product standards, the three basic principles of purpose, maximum freedom and verifiability should be followed.
4.7.1 Principle of Self-discipline
The technical requirements that must be specified in the standard should be selected in a targeted manner according to the product use and the purpose of formulating product standards.
4.7.2 Principle of maximum freedom
When specifying the technical requirements of product standards, in principle, only performance requirements should be specified so that the means to achieve performance requirements can have maximum freedom.
4.7.3 Principle of verifiability
In principle, product standards should only specify requirements that can be verified by test methods, etc. The standard should only specify technical guarantee conditions, and the manufacturer's guarantee cannot replace the technical requirements. 4.8 Basic requirements for writing test (or measurement) methods 4.8.1 Corresponding test methods should be specified for each technical requirement in the standard. Appearance and sensory indicators should be specified as detailed and specific inspection methods as possible.
4.8.2 In principle, only one test method should be specified for each technical requirement, and it must be reproducible. If two or more test methods must be specified for some reason, an arbitration method should be specified; or it should be made clear that various methods have equal effectiveness.
4.8.3 When there is an existing standard test method, do not repeat the test method, but quote it in the standard. 4.8.4 When specifying the instruments and equipment used for the test, the manufacturer or its brand name should not be specified in general. 4.8.5 If the test sequence will affect the test results, the test sequence should be specified. 4.8.6 The test methods and technical requirements can be written in one chapter. In this case, the title of the chapter is "Technical Requirements and Test Methods".
4.9 There are three names and expressions for the chapters on inspection rules, quality assessment procedures, and quality assurance regulations: inspection rules, quality assessment procedures, and quality assurance regulations. When drafting the standard, the name and expression of this chapter are not required to be unified, but depend on the standard system of the product-related profession. If the expression "inspection rules" is used, the content of this chapter is composed of three parts: "final inspection", "handover inspection", and "routine inspection"; "factory inspection", "type inspection", "final test", "handover test", and "routine test" are not used.
4.10 Symbols of measurement units in standards
The legal symbols of measurement units are used in the standards. If necessary, the non-legal measurement units and the corresponding conversion values ​​can be placed in brackets immediately after the legal measurement units: the legal measurement units after the values ​​shall all use unit symbols, and Chinese symbols shall not be used (except for some cases where there are no legal measurement unit symbols). 4.11 Matters to be noted when citing other standards 4.11.1 In order to make the standard as concise as possible, reduce the length and errors, and avoid duplication of the contents of the standards, it is recommended to quote the relevant contents of other standards when drafting the standard. .4·
4.11.2 When citing other relevant standards, the content and revision dynamics of the cited standards should be mastered and understood to ensure the correctness and applicability of the citation.
4.11.3 Except for the standards for certification, which can quote international standards in accordance with the relevant provisions of the National Bureau of Standards document Guobiaofa (1984) No. 274, other standards shall not quote international standards and foreign advanced standards, enterprise standards, and unapproved other draft standards. If necessary, the contents of the above-mentioned relevant parts shall be directly written into the relevant provisions of the draft standard or as an appendix (supplement) to the draft standard.
4.11.4 When a referenced standard appears in this standard for the first time, the code, serial number and name of the standard should be written out in full. When it appears again, only the code and serial number of the standard can be written. If possible, a special chapter "referenced standards" or "related documents" can be listed to list all the referenced standards and documents. When citing some articles in the standard, the numbers of these articles should also be written. 4.12 Punctuation and simplified Chinese characters
Punctuation in the standard must be clearly expressed, and should not be ambiguous or comma-like. The text in the standard should be standardized, and simplified Chinese characters must be simplified Chinese characters officially announced and implemented by the State Council, and self-written characters are not allowed. 4.13 Provisions for filling in additional notes
