In order to ensure the orderly development of standardization activities and promote the realization of standardization goals and benefits, establishing rules for standardization activities has become the primary task of various standardization institutions at home and abroad to carry out standardization activities. In this respect, China has established a basic national standard system to support the development of standards. In this standard system, GB/T 1 Directives for standardization is the basic and general standard guiding standardization activities in China. GB/T 1 aims to establish guidelines generally applicable to the drafting, development and organization of standardizing documents and is intended to consist of three parts. ——Part 1: Rules for the structure and drafting of standardizing documents, for the purpose of establishing the general principles and relevant rules applicable to drafting various standardizing documents. ——Part 2: Procedures for the development of standardizing documents, for the purpose of establishing operable, traceable and verifiable procedures for the development of standardizing document. ——Part 3: standardization technology organization, for the purpose of establishing the organizational hierarchy and stipulating the management and operation requirements for the standardization technology organization so that it can be widely involved by all relevant parties. One of the tasks of standardization activities is to draft high-quality standardizing documents for establishing sound technical rules. To this end, China issued the national standard on the publishing and printing of standards in 1958, and has issued GB/T 1.1 by five editions since 1981, stipulating the rules for the structure and drafting of standards. GB/T 1.1-2009 has been issued and implemented for more than ten years. During this period, the role of standardization has been paid more and more attention to, and the theoretical research and practice of standardization related to standard drafting and the international rules have changed. First of all, the research on standardization principles and methods in China has been deepening, and a classification system for classifying standards from different dimensions has been gradually established. Since 2014, national standards guiding the drafting of standards of different function types and the preparation of content involving safety and environment in standards have been issued one after another, enriching and perfecting the relevant parts of GB/T 20001 Rules for drafting standards and GB/T 20002 Drafting for special aspects in standards. Secondly, with the wide application of GB/T 1.1 and the gradual deepening of standard drafting practice, new demands and suggestions are constantly emerging. Thirdly, ISO/IEC Directives, Part 2, the main international document on which GB/T 1.1 is based, was published in the sixth, seventh and eighth editions in 2011, 2016 and 2018, respectively. In view of this, it is necessary to revise and improve GB/T 1.1, so as to constantly adapt to the new changes of relevant standards at home and abroad and the new demands of the development of standardization practice, and ensure the overall coordination of the basic national standard system supporting the development of standards. To standardize all kinds of standardization subjects, the first thing is to establish provisions, that is, to determine the normative elements of documents; and the second is to develop standardizing documents. This revision of GB/T 1.1 focuses on the general principles and requirements of drafting standardizing documents and how to select the normative elements of documents, clarifies the core technical elements of standards of different function types, and further clearly stipulates the preparation and presentation of document elements. By establishing more rigorous drafting rules, document drafters can have a basis for drafting various standardizing documents, thus improving the quality and application efficiency of documents, promoting the effective display of document functions and better promoting trade, exchange and technical cooperation. Directives for standardization - Part 1: Rules for the structure and drafting of standardizing documents 1 Scope This document establishes the structure of standardizing documents and the general principles and requirements for drafting standardizing documents, and stipulates the document names, levels, rules for preparing and presenting elements, as well as the format of documents. This document is applicable to the drafting of national, professional and provincial standardizing documents, and may be used as reference for other standardizing documents. Note: In case of no confusion, the "standardizing documents" herein is referred to collectively as "documents". 2 Normative references The following documents contain provisions which, through reference in this text, constitute provisions of this document.

China's standardizing documents include standards, standardizing technical guidance documents, and certain parts of documents. International standardizing documents usually include standards, technical specifications (TS), publicly available specifications (PAS), technical reports (TR), guides, and certain parts of documents. Note 1: In addition to China's standardizing documents, the above-mentioned international standardizing documents may also be referenced to. Note 2: Parts are levels to which a document may be divided. However, since a part can be independently prepared, revised and issued (see 7.1.1.1), the standardizing document used in this document contains "part(s)" unless it is necessary to point out "part(s)" separately. 4.2 Confirming the categories of standards can help drafters draft standards with better fitness for implementation. Standards may be classified into different categories according to different attributes. a) According to the standardization subjects, standards may be classified into the following subject categories:  product standard, which specifies the requirements that products need to meet to ensure their fitness for implementation;  process standard, which specifies the requirements that the process needs to meet to ensure its fitness for implementation;  service standard, which specifies the requirements that the service needs to meet to ensure its fitness for implementation. Note: According to specific standardization subjects, product standards are usually further classified into raw material standards, part/component standards, finished product standards, system standards, etc. Among them, the system standard refers to the standard that specifies the requirements that the system needs to meet to ensure its fitness for implementation. b) According to the function of standard content, standards may be classified into the following function types:  terminology standard: the standard that defines the reference and definition of concepts used in specific fields or disciplines;  symbol standard: the standard that defines the presentation form, meaning or name of symbols used in specific fields or disciplines;  classification standard: the standard that regularly divides and arranges product processes or services or establishes a classification system based on similar characteristics such as source, composition, performance or use;  test standard: the standard that comprehensively describes the test activities and the way to draw conclusions within the precision range suitable for the specified purpose and under the given environment;  specification standard: the standard that specifies the requirements to be met for products, processes or services and describes the verification method used to determine whether the requirements are met;  code of practice standard: the standard that specifies clear procedures for the process of activities and describes the traceability/verification method used to determine whether the procedures are performed;  guide standard: the standard that provides universal, principled and directional guidance on a subject with appropriate background knowledge, or gives relevant suggestions or information at the same time. 5 Objectives, principles and requirements 5.1 Objectives and general principles Documents are prepared to provide a framework for future technological development by specifying clear, accurate and unambiguous provisions, and to be understood and easily applied by professionals who have not participated in the preparation of documents, thus promoting trade, exchange and technical cooperation. In order to achieve the above objectives, the following general principles should be observed when drafting documents: the latest technical level and current market conditions are fully considered, and the standardization needs in the fields involved are carefully analyzed; on the basis of accurately grasping standardization subjects, document users and document preparation purposes (see 5.3), the categories and/or function types of documents are defined (see Clause 4), the normative elements of documents are selected and determined, the levels and elements of documents are reasonably set and prepared, and the technical contents of documents are accurately expressed. 5.2 Principles of preparing a document as a whole or in parts 5.2.1 For a standardization subject, it is usually advisable to prepare a whole document without subdivision, but a document with several parts may be prepared under special circumstances. With comprehensive consideration of the following situations, a document may be prepared with several parts with regard to a standardization subject: a) the document is likely to become too long; b) the document users have different needs, such as producers, suppliers, purchasers, testing institutions, certification institutions, legislative bodies, management institutions, etc.; c) documents are prepared for different purposes, such as ensuring usability, facilitating interface, interchange, compatibility or mutual cooperation, facilitating variety control, ensuring health and safety, protecting environment or promoting rational utilization of resources, and promoting mutual understanding and communication. 5.2.2 Generally, the contents applicable to a wide range of general standardization subjects should be prepared as a whole document; the general contents applicable to a narrow range of standardization subjects should be prepared as a general part of a document consisting of several parts; the specific contents applicable to a simple range of standardization subjects should not be prepared as a whole document or a part of a document consisting of several parts, but only as relevant elements in a document. For example, the test method which is applicable to a wide range of products shall be prepared as a test standard; the test method which is applicable to a certain type of products shall be prepared as a test method part of a document consisting of several parts; the test method which is applicable to testing the specific characteristics of a product shall be prepared as the "test method" element in the product standard 5.2.3 Before drafting documents, it is advisable to consider and establish: ——the reasons for dividing the document into parts (see 5.2.1) and the relationship between these parts; ——the name and scope of each part expected in a document which is divided into parts. 5.3 Selection principles of normative elements 5.3.1 Standardization subject principle The standardization subject principle means that the related contents of standardization subject or field need to be considered when drafting a document, in order to confirm whether the product/system process or service or the contents related to a certain field are to be standardized, and whether it is a complete standardization subject or a certain aspect of the standardization subject, thus ensuring that the contents in the normative elements are closely related to the standardization subject or field. Standardization subject determines the subject category [see 4.2a)] of the drafted standard, which directly affects the composition of normative elements in the document and the selection of technical contents. 5.3.2 Document user principle The document user principle means that document users [see 5.2.1b)] need to be considered when drafting a document, so as to confirm which users the document is aimed at, and whether they are concerned about the results or the process, thus ensuring that the contents in the normative elements are needed by specific users. Different users of the document will influence the identification of a document as a specification standard, code of practice standard or test standard [see 4.2b)], and then the composition of normative elements in the document and the selection of its contents will be different. 5.3.3 Aim-oriented approach The aim-oriented approach means that the preparation purpose [see 5.2.1c)] of the document needs to be considered when drafting a document, and functional analysis will be carried out on the standardization subject based on the confirmed preparation purpose to identify the contents or characteristics to be standardized in the document, thus ensuring that the contents of normative elements are selected for the preparation purpose of the document. The preparation purpose of a document determines the purpose category of the standard. The contents or characteristics that need to be standardized in normative elements vary with the preparation purposes. The more purposes of preparation, the more contents or characteristics are selected. Note 1: If a document is prepared for the purpose of promoting mutual understanding, the purpose category of the standard formed is the basic standard; if a document is prepared for the purpose of ensuring usability, interchangeability, compatibility, mutual cooperation or variety control, the purpose category of the standard formed is the technical standard; and if a document is prepared for the purpose of ensuring health and safety and protecting the environment, the purpose category of the standard formed is the health standard, safety standard or environmental protection standard. Note 2: The basic standards prepared for the purpose of promoting mutual understanding include function types such as terminology standard, symbol standard, classification standard and test standard; and the standards prepared for other purposes include function types such as specification standard, code of practice standard and guide standard. [See 4.2b)]. 5.4 Presentation principles of documents 5.4.1 Consistency principle Within each document or among the parts of a document, the structure and the presentation of elements should be consistent. Therefore: ——the same provisions should be presented with the same wording and similar provisions should be presented with similar wordings; ——the same concept should be presented with the same term other than synonyms; ——the titles and numbers of elements with similar contents should be the same as far as possible. Note: Consistency is especially important to help document users understand the contents of documents (especially documents divided into parts), and it is also important to use automatic text processing technology and computer-aided translation. 5.4.2 Coordination principle The documents drafted should be coordinated with the current valid documents to avoid duplication and unnecessary deviations. Therefore: ——as far as possible, the requirements for one standardization subject should be confined to one document. ——general contents should be specified in one document to form a general standard or general part (see 5.2.2); ——the drafting of documents should comply with the requirements of the basic standards and the general standards in the field, and the applicable international documents, if any, should be adopted as far as possible; ——where it is necessary to use contents in other locations of the document itself or contents in other documents, the presentation form of reference (see 9.5.4) or notes (see 9.5.5) should be adopted. 5.4.3 Accessibility principle The presentation of the contents of documents should be convenient for direct application, and easy to be referenced or excerpted by other documents. 5.5 General requirements 5.5.1 In drafting the document, the intended structure (see 6.2) and any interrelationships of the document shall be determined on the basis of selecting normative elements. 5.5.2 In order to improve the fitness for implementation and application efficiency of the documents and ensure the timely release of the documents, the draft documents in each stage of the preparation work shall meet the following requirements on the basis of conforming to the drafting rules stipulated in this document: ——the standards of different function types [see 4.2b)] shall comply with the requirements of corresponding parts of GB/T 20001; ——some specific contents in the document shall comply with the relevant requirements of GB/T 20002; ——the Chinese documents identical to the international documents shall comply with the requirements of GB/T 20000.2. 5.5.3 A document shall not include contractual requirements (e.g. concerning claims, guarantees, covering of expenses) and legal or statutory requirements such as administrative measures, legal responsibilities and penalties.
