GB/T20000.2—2009
The method of adopting international standards by national standards and the classification system of the degree of consistency between national standards and international standards specified in this part of GB/T20000 will promote the standardization of my country's adoption of international standards. The method of adopting other types of documents other than international standards [such as technical specifications (TS), publicly available specifications (PAS), technical reports (TR), guides (Guide), technology trend assessments (TTA), industrial technology agreements (ITA), international workshop agreements (IWA)] published by ISO or IEC is specified in another part of GB/T20000. International standards are usually the crystallization of the experience of the global industry, researchers, consumers and regulatory agencies, and contain the common needs of various countries. Therefore, the adoption of international standards is one of the important foundations for eliminating technical barriers to trade. This has been clearly recognized in the World Trade Organization's "Agreement on Technical Barriers to Trade" (WTO/TBT Agreement). In order to develop foreign trade, it is very important to adopt and use international standards as much as possible.
In order to compare national standards with corresponding international standards and quickly understand the relationship between them, it is very important to indicate the degree of consistency between them. Since the circumstances when adopting international standards are different, it is unreasonable to divide the degree of consistency in too much detail. It is sufficient to divide the degree of consistency into three categories (see 4.2 to 4.4). The equivalent adoption of international standards can ensure the transparency of national standard formulation, which is a basic condition for promoting international trade. Because even if different national standard organizations have only made some minor changes in their opinion when adopting the same international standard, these changes may be added together to make different national standards mutually unacceptable, and the equivalent adoption of international standards can avoid these problems. Even if international standards cannot be equivalently adopted due to climatic, geographical or basic technical reasons, every effort should be made to minimize the differences between national standards and corresponding international standards. When there are differences between national standards and international standards, it is very important to clearly indicate these differences on the national standards and explain the reasons for these differences. If these differences are not indicated, it will be difficult to identify the technical differences due to the different expressions or structures of the national standard and the corresponding international standard. In addition, the indication of differences can remind the drafter at any time to consider whether these differences are still necessary; even if the differences are no longer necessary, they may be ignored and remain in the standard. 1 Scope
Guidelines for standardization work
Part 2: Adoption of international standards
This part of GB/T 20000 specifies:
Methods for determining the degree of consistency between national standards and corresponding international standards; - Methods for adopting international standards;
- Methods for identifying and expressing technical differences and editorial changes; - Methods for numbering national standards that are equivalent to ISO standards and IEC standards; - Methods for indicating the degree of consistency between national standards and corresponding international standards This part applies to national standards adopting international standards, and can also be used as a reference for other standards when adopting international standards. GB/T20000.2--2009
The numbering method for national standards equivalent to ISO standards and (or) IEC standards specified in Chapter 7 of this Part does not apply to standards published by other international standardization organizations that adopt ISO standards. Normative references

The content acceptable in international standards is also acceptable in national standards, and vice versa. Therefore, compliance with national standards means compliance with international standards. 4 Degree of consistency
14.1 General
The degree of consistency between national standards and corresponding international standards is divided into: equivalence (see 4.2), modification (see 4.3) and non-equivalence (see 4.4). 4.2 Equivalence
When the degree of consistency between national standards and corresponding international standards is "equivalence", the following situations exist: the technical content and text structure of national standards and international standards are the same, but the following minimum editorial modifications may be included: - Use the decimal point symbol ".\Replace the symbol ","; Correct printing errors:
- Delete one or more language texts in the international standard version published in multiple languages; - Incorporate the content of amendments or technical corrections to international standards; - Change the name of the standard to be consistent with the existing standard series; - Replace "this international standard" with "this standard"; Add informative elements (such as informative appendices, such appendices do not change, add or delete the provisions of the international standard). Usually informative elements include recommendations for standard users, training guidelines or recommended forms or reports; Delete the informative overview elements in the international standard (including cover, table of contents, foreword and introduction); If different measurement units are used, add unit conversion content for reference. Under the condition of "equivalence", the "vice versa principle" applies. Note: Changes in the format of the document (for example, changes in page numbering, font, font size, etc.), especially when computer editing is used, do not affect the degree of consistency. 4.3 Modification
When the degree of conformity between a national standard and the corresponding international standard is "modification", one or both of the following situations exist: technical differences, and these differences and the reasons for their occurrence are clearly stated; a change in the text structure, but at the same time there is a clear comparison. When the degree of conformity is "modification", a national standard may also contain editorial modifications. A national standard should adopt an international standard as much as possible. In individual cases, a national standard is allowed to adopt several international standards only when the technical differences and their reasons are clearly stated in a list form and can be easily compared with the structure of the corresponding international standard. 2

a) The content of the national standard is less than the corresponding international standard: the requirements of the national standard are less than those of the international standard, and only some of the optional contents of the international standard are adopted.
The content of the national standard is more than the corresponding international standard: the requirements of the national standard are more than those of the international standard, and the content or types are increased, including additional tests.
The national standard changes part of the international standard: the national standard and the international standard have part of the same content, but both contain requirements that are different from the other party.
d) The national standard adds another alternative: the national standard adds a clause with the same status as the corresponding international standard clause as another alternative to the clause of the international standard. For examples of stating and explaining technical differences, see Appendix C. Under the "modification" condition, the "vice versa principle" does not apply. Note: The national standard may include the entire content of the corresponding international standard and also include additional technical content that is not part of the international standard. In this case, even if no modification is made to the included international standard, its degree of consistency can only be "modification" or "non-equivalence". Whether it is "modification" or "non-equivalence" depends on whether the technical differences are clearly marked and explained. 4.4 Non-equivalence
When the degree of consistency between the national standard and the corresponding international standard is "non-equivalence", the following situation exists: the technical content and text structure of the national standard and the international standard are different, and this difference is not clearly stated in the national standard. "Non-equivalence" also includes the situation where only a small number or insignificant international standard clauses are retained in the national standard. National standards with a "non-equivalent" degree of consistency with international standards do not belong to the adoption of international standards.
5 Methods for adopting international standards
5.1 General
5.1.1 When adopting standards or other publications published by ISO, IEC and other international standardization organizations published by ISO, it is necessary to pay attention to the provisions of ISO, IEC and other international standardization organizations published by ISO on the copyright, copyright use rights and sales of their publications. 5.1.2 For different types of documents including international standards published by international standardization organizations, it is advisable to adopt Chinese documents of similar types to international documents
5.1.3 National standards should adopt international standards as much as possible. If international standards are modified due to climate, geography or basic technical reasons, the differences with international standards should be minimized, and these differences and the reasons for these differences should be clearly marked. 5.1.4 National standards that have a consistent correspondence with international standards should be written in accordance with the provisions of GB/T1.1. Note: The structure of standards published by other international standardization organizations published by ISO is often different from the standard structure specified in GB/T1.1. National standards that have a consistent correspondence with international standards should indicate the degree of consistency with international standards on the cover (see 8.3.1), and state in the foreword the international standard method adopted, the degree of consistency with the adopted international standard, the international standard number and the Chinese translation of the international standard name (see Appendix D). In the foreword, the minimum editorial changes made should be stated when adopting an equivalent (see 6.1.3); when adopting a modified version, the technical differences (see 6.1.1) and editorial changes (see 6.1.3) and structural changes (see 6.1.2) should be stated; when it is not equivalent to an international standard, it is not necessary to state the technical differences and editorial changes and structural changes. National standards that have a consistent correspondence with international standards should not retain the foreword of the international standard. The content of the introduction of the international standard can be converted into the introduction of the national standard as needed, or the introduction of the international standard can be deleted. 5.1.5 When adopting an international standard, all amendments and technical corrections to the international standard that have been published should be incorporated into the national standard. The foreword of the national standard should include the addition of amendments to the international standard. For an explanation of the contents of corrections and technical corrections and the method of marking, see 6.1.43 for the method of marking amendments and technical corrections included in the standard text.

GB/T20000.2-—2009
After a national standard adopts an international standard, it is advisable to adopt the newly published amendments and technical corrections to the international standard as soon as possible. 5.1.6 With the development of the electronic version of the standard, new methods of adopting international standards that are not included in this part, or new methods combined with existing methods may emerge. When using new methods, the provisions of this part on the division and marking of the degree of consistency still apply. 5.2 Translation method
5.2.1 Translation method refers to the translation of the corresponding international standard into a national standard. Minimal editorial changes may be made (see 4.2). For the translation of auxiliary verbs in the clauses of international standards, see Appendix E. 5.2.2 National standards using the translation method may be subject to minimal editorial changes. If it is necessary to add informative appendices, these appendices should be placed after the appendices of the international standard and the order of the appendices should be arranged in the order in which these appendices are mentioned in the text. The number of each appendix consists of the word "Appendix" plus the symbol "N" representing the national appendix followed by uppercase Latin letters indicating the order, starting with "A", for example: "Appendix NA", "Appendix NB", etc. The numbering of chapters, figures, tables and mathematical formulas in each appendix should start from 1, and the number should be preceded by the symbol "N" representing the national appendix followed by an uppercase Latin letter indicating the order of the appendix. , followed by a footnote, for example, chapters in Appendix NA are indicated by "NA.1", "NA.2", etc., and figures are indicated by "Figure NA.1", "Figure NA.2", etc. 5.3 Redrafting method
5.3.1 The redrafting method refers to rewriting the national standard based on the corresponding international standard. 5.3.2 If the national standard adopting the redrafting method needs to add annexes, each added appendix should be numbered together with other appendices in the order mentioned in the standard text.
5.4 Selection of international standard method
5.4.1 When international standards are adopted identically, the translation method should be used. 5.4.2 When international standards are adopted with modifications, the redrafting method should be used. Note: The correspondence between the international standard method and the degree of consistency is shown in Appendix F. Appendix F contains the methods used when the degree of consistency is non-equivalent. 6 Expression and indication of technical differences and editorial changes 6.1 General
6.1.1 When the technical differences (and their causes) are minor, they should be stated in the foreword of the national standard (see Example 2 in Appendix D). When the technical differences (and their causes) are major, they should be indicated with a vertical single line (I) in the outer margin of the clauses involved in the text, and an appendix should be compiled to list a table summarizing all the differences and their causes (see Appendix G). The appendix should be pointed out in the foreword and explain how to indicate these technical differences in the text (see Example 3 in Appendix D). 6.1.2 When the structural adjustments are minor, they should be stated in the foreword of the national standard. When the structural adjustments are major, an appendix should be compiled to list a comparison table of chapter and article numbers between national standards and international standards (see Appendix G). The appendix should be pointed out in the foreword (see Example 3 in Appendix D).
6.1.3 When there are editorial changes, the national standard adopted equivalently shall only state the following editorial changes in the preface: - Incorporation of the contents of the international standard amendment or technical correction; - Change of the standard name;
Addition of informative appendix;
Addition of unit conversion contents.
In addition to stating the above four minimum editorial changes, the national standard adopted by modification shall also state other editorial changes other than the minimum editorial changes listed in 4.2 in the preface, such as deletion or modification of the informative appendix of the international standard. 4

6.1.4 Amendments and (or) technical corrections of international standards shall be directly incorporated into the provisions of national standards, and shall be marked with a vertical double line (Ⅱ) in the outer margin of the modified provisions. 6.2 The adopted international standards refer to other international documents 6.2.1 For national standards that adopt international standards equivalent to international standards, international documents that are normatively referenced by international standards with dates can be replaced by Chinese documents that are equivalent to these documents. In this case, these replaced Chinese documents should be listed in the "Normative Reference Documents" chapter of the national standard, and the consistency level with the corresponding international documents should be marked (see 8.3.2). For international documents that are normatively referenced by international standards without dates, all references should be retained. In this case, these retained international documents should be listed in the "Normative Reference Documents" chapter of the national standard (if it is a standard, the international standard number, the Chinese translation of the international standard name and the original name enclosed in brackets should be included), and Chinese documents that have a consistent correspondence with these documents should be listed in the preface. If there are many Chinese documents that need to be listed, it is advisable to compile an informative appendix to list them (see 8.3.2).
6.2.2 For national standards that modify the adoption of international standards, international documents that are normatively referenced by international standards can be replaced by applicable Chinese documents. In this case, these applicable Chinese documents should be listed in the chapter "Normative References" of the national standard. For Chinese documents that have a consistent correspondence with international documents, the consistency level with the international documents should be marked (see 8.3.3). If a Chinese document that is not equivalent to an international document, or a Chinese document that has no consistent correspondence with an international document, is used to replace an international document normatively referenced by an international standard, the national standard should briefly explain the technical differences between the Chinese document that is not equivalent or has no consistent correspondence and the corresponding international document in terms of the relevant contents of the reference when stating the technical differences. For international documents normatively referenced by international standards that are retained, these retained international documents should be listed in the chapter "Normative References" of the national standard (if they are standards, they should include the international standard number, the Chinese translation of the international standard name, and the original name enclosed in brackets).
6.2.3 For national standards that are not equivalent to international standards, international documents normatively referenced by international standards can be replaced by applicable Chinese documents. In this case, these applicable Chinese documents should be listed in the chapter "Normative Reference Documents" of the national standard. For Chinese documents that have a consistent correspondence with international documents, the degree of consistency with international documents may not be marked, or only the code and sequence number of the corresponding international document may be marked.
For international documents that are normatively referenced by international standards that are reserved, these reserved international documents should be listed in the chapter "Normative Reference Documents" of the national standard (if they are standards, they should include the international standard number, the Chinese translation of the international standard name, and the original name in brackets).
6.2.4 For references mentioned in international standards, applicable Chinese documents can be used instead. In this case, these applicable Chinese documents can be listed in the "References" of the national standard. For Chinese documents that have a consistent correspondence with international documents, the degree of consistency with international documents may not be marked. The names of international documents in the reserved references do not need to be translated into Chinese. 7 Numbering method for ISO standards or IEC standards that are equivalent 7.1 Overview
When a national standard is equivalent to an ISO standard and/or IEC standard, the information of "equivalence" should be made clear to the reader before reading the content. For this purpose, the following abbreviation method is used. 7.2 Numbering
The numbering method for ISO standards and/or IEC standards that are equivalent to national standards is the same as the numbering method for ISO standards and/or IEC 1) In this part, "Chinese documents" refer to national standards, national standardization guidance technical documents, industry standards, 5
