class="f14" style="padding-top:10px; padding-left:12px; padding-bottom:10px;"> GB/T1 "Guidelines for Standardization Work" together with GB/T20000 "Guidelines for Standardization Work", GB/T20001 "Rules for Writing Standards" and
GB/T20002 "Drafting of Specific Content in Standards" constitute a basic series of national standards to support the formulation and revision of standards.
GB/T1 "Guidelines for Standardization Work" is divided into two parts:
--- Part 1: Structure and Writing of Standards;
--- Part 2: Procedure for Formulating Standards.
This part is Part 1 of GB/T1.
This part replaces GB/T 1.1-2000 "Guidelines for standardization work Part 1: Structure and writing rules for standards" and GB/T1.2-2002 "Guidelines for standardization work Part 2: Methods for determining the content of normative technical elements in standards". This part is mainly based on GB/T1.1-2000 and integrates part of GB/T1.2-2002. Compared with GB/T1.1-2000, the main technical changes are as follows, except for editorial changes:
--- Added the provisions that the subdivision of untitled items should be avoided and the expression form that can emphasize the key terms or phrases in untitled items (see 5.2.4);
--- Added the expression form that can emphasize the key terms or phrases in the listed items (see 5.2.6);
--- In the provisions of the preamble, deleted the statement of the nature of the appendix, added the drafting rules based on the preparation of the standard and the relevant instructions on patents (see 6.1.3, 6.1.3 of the 2000 edition); ---

GB/T1 "Guidelines for Standardization Work" together with GB/T20000 "Guidelines for Standardization Work", GB/T20001 "Rules for Writing Standards" and GB/T20002 "Drafting of Specific Contents in Standards" constitute a series of basic national standards that support the formulation and revision of standards. GB/T1 "Guidelines for Standardization Work" is divided into two parts: Part 1: Structure and Writing of Standards;
Part 2: Procedure for Formulating Standards.
This part is Part 1 of GB/T1.
This part replaces GB/T1.1-2000 "Guidelines for Standardization Work Part 1: Structure and Writing Rules for Standards" and GB/T1.2-2002 "Guidelines for Standardization Work Part 2: Methods for Determining the Content of Normative Technical Elements in Standards". This part is based on GB/T1.1-2000 and integrates some contents of GB/T1.2-2002. Compared with GB/T1.1-2000, the main technical changes are as follows, except for editorial changes:
- Added the provision of "avoiding the subdivision of untitled items" and the expression form that can emphasize the key terms or phrases in untitled items (see 5.2.4):
Added the expression form of key terms or phrases in the emphasized items (see 5.2.6); In the provisions of the preamble, deleted the statement of the nature of the appendix, added the drafting rules based on which the standard was compiled, and the relevant instructions on patents involved (see 6.1.3, 6.1.3 of the 2000 edition); In the provisions of the introduction, added the relevant instructions on patents involved in the standard (see 6.1.4); In the provisions of the list of normative references, added the rules for listing online documents (see 6.2.3); Modified the marking of the international documents in the standards listed in the list of normative references According to the provisions of the corresponding relationship, only the Chinese standards that are being drafted and have a certain degree of consistency with international documents need to be marked (see 6.2.3 of the 2000 edition, 6.2.3); the introduction to normative references and terms and definitions has been modified (see 6.2.3 and 6.3.2, 6.2.3 and 6.3.1 of the 2000 edition);
In addition to the appendix "Drafting and Expression of Terms and Definitions", the content related to "Terms and Definitions" in the preparation of non-terminology standards has been moved to the main text (see 6.3.2, Appendix C of the 2000 edition); "Selection of Technical Elements" has been added (see 6.3 .1); deleted the content related to product standards in the normative technical requirements (see 6.3.4, 6.3.5 and 6.3.7 of the 2000 edition); added "expression of technical elements" (see 7.1.3); - added rules on the connection and sub-drawing of figures (see 7.3.7 and 7.3.10); added the principles to be followed by formal published documents other than normative reference standards (see 8.1.3.1); added the requirements for stating relevant patents (see 8.4 and Appendix C); added "selection of numerical values" (see 8.5); modified the format of the table of contents (see 9.3, 2000 edition); 7.3 of the 2000 edition); modified the line spacing of chapter titles and article titles (see 9.9.1, 7.6 of the 2000 edition); deleted the provisions for subdivision in the list (see 7.7 of the 2000 edition); deleted the provisions for the continuation of multiple appendices (see 7.13 of the 2000 edition); added the line spacing provisions for the figure and the preceding article, the table and the following article, and the figure and table titles (see 9.9.6); added detailed provisions for the marking of standardized items (see Appendix E); added auxiliary verbs indicating possibility, and modified the equivalent expression form of auxiliary verbs (see Appendix F, Appendix E of the 2000 edition).

GB/T1.1-2009
In the past fifty years, GB/T1 has played an important guiding role in the formulation and revision of standards in my country through continuous implementation, revision and improvement. Since the release of GB/T1.1-2000 and GB/T1.2-2002, we have received many revision opinions and suggestions from standard users, and encountered some new problems in the application of the standards. In addition, the ISO/IEC Guide, the main international document based on GB/T1, has been revised and published in 2004. The ISO/IEC Guide is divided into two parts, and the original Part 3 has been merged with Part 2. In order to meet the needs of the development of my country's standardization work, further coordinate with the new version of the ISO/IEC Guide, and promote trade and exchanges, it is necessary to revise GB/T1.
All previous versions of GB/T1.1 were drafted based on the ISO/IEC Guide. The ISO/IEC Guide is represented by the traditional manufacturing industry and is written with product standards as an example, while GB/T1.1 is the basic standard that all industries in the country follow when abbreviating standards, and its scope of concern should be wider. Therefore, this revision pays more attention to the characteristics of my country's standards, and mainly stipulates the compilation of information overview elements, normative general elements and information supplementary elements that are generally applicable to various standards, as well as several common elements in normative technical elements, while the compilation of other elements in normative technical elements is stipulated in the relevant basic standards (GB/T20000, GB/T20001 and GB/T20002). The adjusted GB/T1.1 is more suitable for the compilation of various standards. X

4.1 Objectives
The objective of developing standards is to provide clear and unambiguous provisions in order to facilitate trade and communication. To this end, standards should: strive to be complete within the limits specified by their scope; be clear and accurate;
- take full account of the state of the art (see 3.9); provide a framework for future technological development;
be understandable to professionals who have not participated in the preparation of the standard. 4.2 Uniformity
The style and terminology of the standard should be consistent within each standard or series of standards (or different parts of a standard). The structure of each standard in a series of standards (or different parts of a standard) and the numbering of its chapters and clauses should be as similar as possible. Similar clauses should be expressed in similar terms; identical clauses should be expressed in identical terms. In each standard or series of standards (or different parts of a standard), the same term should be used for the same concept. Synonyms should be avoided for defined concepts. Each selected term should have as unique a meaning as possible. 4.3 Coordination
In order to achieve the goal of overall coordination of all standards, the preparation of standards should comply with the relevant provisions of the current basic standards, especially the following aspects: standardization principles and methods;
