This standard specifies the codes for units of measurement used in administration, commerce, transport, science and technology, and industry for length, mass (weight), volume, and other quantities. The codes provided in this standard are applicable to manual and automatic information exchange between parties involved in international trade and other economic, scientific and technological activities.

GB/T 17295—1998
The Opinions on Comprehensively Promoting my country's Legal Units adopted by the State Council in 1984 stipulates: "In some scientific and technological fields, if there is a special need, some non-legal units of measurement may be used, but they must be consistent with the names and symbols stipulated by relevant international organizations." Based on this principle, in order to meet the needs of my country's foreign trade, this standard was formulated with the participation of the United Nations Economic Commission for Europe (UN/ECE) Recommendation No. 201 & Code of Units for International Trade (1995 Edition). The names and symbols of the units of measurement are basically the same as those in the recommended standard: individual symbols have been appropriately modified according to GB310~3102-93. The United Nations Economic Commission for Europe (UN/ECE) Recommendation No. 20 not only includes the measurement primaries specified in the International System of Units (SI), but also includes other measurement units commonly used in international trade, and provides a transition period for the unification of SI. During the transition period, some measurement units that are not comparable to SI will be gradually eliminated.
The original text of the UN/ECE Recommendation No. 2C includes the main text, Appendix A, Appendix B, Appendix C and Appendix D. The main text consists of 9 parts: preface, introduction, specification, application field, definition, reference text, code table collection principles, code structure and representation, and maintenance rules. Appendix A is a code element description. Appendix B, Appendix C and Appendix D It is the relevant content of measurement units listed in the form of a table. The measurement units marked with ※ in the code table of this standard are the legal measurement units of my country, which are equivalent to GB3102-93. When using this standard, the various standard application departments of my country should give priority to the legal measurement units of my country. This standard has made the following adjustments to the UN/ECE 20th recommended standard in terms of structure and content: 1. According to the provisions of GB/T1.11933, the main text has been re-arranged, the instructions in the original recommended standard that are not related to the use of this standard have been deleted, and the descriptions of this standard have been added with reference to GB310~3102-93. Description of technical contents. 2. Appendix A of the original recommended standard is an explanation of the code structure of accounting units in the first edition (1985 edition) of the recommended standard. The revised edition (1995 edition) is mainly to compile common codes, so Appendix A of the original recommended standard has been deleted, and the original 4 appendices have been reduced to 3 appendices. 3. The procedural content of the maintenance of the code table in China stipulated in the recommended standard is changed to the procedural content of my country's maintenance of this standard. 1. In order to comply with the relevant provisions of the compilation of information classification and coding standards in my country, based on Appendix B of the original recommended standard (i.e. Appendix A of this standard), add the column "General Code".
5. Appendix D of the original recommended standard is a comparison table of the first edition packaging type code (GB/T16472-1996) of the recommended standard and the American National Standards Institute standard data element 355 measurement unit code (A.VSIA.SC.X12T-355), which is used as Appendix C (indicative appendix) of this standard. 6. In order to meet the needs of my country's trading parties during the transition period, the conversion values ​​of British units are added to the "conversion factors and notes" to accurately use units outside the SI system.
Appendix A and Appendix B of this standard are standard appendices, and Appendix C is an indicative appendix. This standard is proposed by the China Institute of Standardization and Information Classification and Coding. The drafting units of this standard are: China Institute of Standardization and Information Classification and Coding, and the Unit System Office of the State Administration of Investment and Technology. The main drafters of this standard are Zhang Rongjing, Fang Qing, Li Ba, and Zhao Yan. 388

UN/ECE Foreword
UN/ECE Recommendation No. 20 Codes of Units of Measurement for Use in International Trade, a revised version, was formally adopted by the United Nations Economic Commission for Europe (UN/ECE) Working Group on Simplification of International Trade Procedures (WP.4) of the State Council Administrative Department for Standardization at its 52nd meeting in September 1995. Its number is: ECE/TRADE/R.888/Rev.4. The revised version of this recommended standard strives to achieve: standardization for easy communication
by clarifying and simplifying the use of units of measurement!
|| to meet the needs of actual users;
|| to facilitate the maintenance and coordination of code entries. To this end, this standard provides a list of unit codes widely used in administration, commerce, transportation, science and technology. P.4 Consultations were held with ISO/TC12 with interested countries during the preparation of this standard, as well as with relevant bodies of the Inland Transport Committee of the European Community and other international organizations interested in the ECE Recommendation on Simplified Trade, in particular the World Customs Organization (WCO). Representatives of regional and national organizations participating in meetings of Expert Group 1 (Data Elements and Automatic Data Exchange) and of the Working Group also contributed to the preparation of this Recommendation. The Working Group on Simplified International Trade Procedures recommends that all parties involved in international trade use the unit codes described in this Recommendation when they need to use them. The units listed in this Recommendation provide users with an indication of physical quantities currently in use in international or regional trade. The units included do not include units of address or non-physical quantities, nor do they include units of measurement that were once in use but are no longer in use. SEs

This standard uses the following definitions:
Unit of measure
A specific quantity defined and adopted by agreement, with which other quantities of the same kind can be compared, to indicate the value given relative to its size. 4 Code table collection principles
4-1 Taking into account the specific country of this standard, this code table is based on the legal measurement units of my country and includes other measurement units commonly used in international trade, and is divided into three levels:
Level 1 (standard level): units in GB3IC2 expressed in SI, including relevant units in GB3100~3102 plus SI prefixes (decimal sieve units and fractional units);
State Administration of Technical Supervision 199-03 -27 approved
1998-10-01 implementation
GB/T17295—1998
Level 2 (equivalent standard level): units in centimeter-gram-second system (cgs)/foot-pound-second system (fps)/UK/ES that can be interchanged with SI units:
Level 3 (prompt level); all the measurement units included are not suitable for inclusion in levels 1 and 2, but are only to meet the needs of actual users. 4.2 Principles for the inclusion of measurement units in the code table: only units with SI prefixes are included, such as units consisting of mega (M) and giga (G)! Units used to mark difficult screening numbers are not given codes as independent units, such as units composed of 10 megabytes and 100 megabytes. Numerical values ​​are not measurement units, such as 10 and 25, and no code form is given.
5 Code structure and representation
5.1 This standard compiles universal codes for measurement units based on the letter codes for measurement units in the first edition of UN/ECE Recommendation No. 20 and the alphanumeric codes for measurement units in the American National Standards Institute Standard Data Element 355 (ANSI ASC X12T-355). 5.2 The code value of the universal code is represented by three alphanumeric characters of indefinite length (an..3). 5.3 Principles for compiling universal code values ​​
5.3.1 It is preferred to use the existing code values ​​in the first edition of UN/ECE Recommendation No. 20 or ANSI ASC X12T-355; when two code values ​​indicate two measurement units at the same time, only the code value in the first edition of UN/ECE Recommendation No. 20 is retained. 5.3.2 When there is no existing code value, the new universal code is coded in the format of letter-number-number (ann) from A01 to Z99. 6 Composition and explanation of the code table
6.1 The code table consists of three parts:
Appendix A (standard appendix) is a code table arranged by quantity and information of measurement units; Appendix B (standard appendix) is a code table arranged by the English name of measurement units; Appendix C (informative appendix) is a code table arranged by the universal code of measurement units. 6.2 Composition of the code table in Appendix A
Appendix A is a code table of measurement units arranged by quantity and information. The columns include quantity, grade/category, use identification, unit name, conversion factor and remarks, representation symbol, universal code, and document reference number. 6.2.1 Abbreviation of physical quantity. The property of phenomena, objects and substances that is qualitatively distinguished and determined by quantification. The units of measurement in levels 1 and 2 (standard level and equivalent standard level) are listed in the title of this part according to their attributes. The units of measurement in level 3 are divided into 9 categories as defined in 6.2.2 Level/Category. In the case of large numbers, only one name is given for each quantity. When more than two names are given for a basis without distinction, they are in an intermediate position.
Some Chinese names of quantities are enclosed in parentheses. The name in the parentheses is a synonym of the previous name (except for explanatory text). Some Chinese names of quantities are enclosed in square brackets. The characters in the square brackets are retained as the full name, and the abbreviation is omitted if the characters in the square brackets are omitted. The characters in the square brackets can be omitted without causing confusion or misunderstanding. 6.2.2 Level/Category
The symbol of the standard level or indicative level of measurement unit, 1 represents SI unit, Decimal multiple units and fractional units and customary units (standard numbers). Decimal multiple units and fractional units are marked with S, and customary multiple units are marked with M.
2 Indicates SI equivalent units and customary multiples (equivalent standard level). Decimal multiple units and fractional units are marked with S, and slow multiple units are marked with M
3 Indicates 9 categories of units classified by information:
3.1 Defined units in level 1 and level 2 units3.2 Sales units
3.3 Packaging units
3-4 Shipping and transportation units
3.5 Special industrial units (various)
3.6 Information technology units
3.7 Integers/numbers or/coefficients
3.8 Multiple factors
3.9 Miscellaneous
CB/T 17295--1998
The units of measurement in level 3 (except for the miscellaneous units in 3.5 and 3.9) are subdivided into: A—Units generally used internationally
B—Units used at the regional level with broad international interests; C—Units used only in regions or industries. 6.2.3 Usage symbols
X—These units are restricted in use.
2: These units will be phased out before 1999. They are included in the table for information purposes. 6.2.4 Unit names
The naming of the Chinese names of English units is based on the provisions of Chapter 5 of GB 3100--93. The Chinese names of some units are enclosed in parentheses. The name in the parentheses is the name preceding it. The synonyms of the name (except for the English, American or explanatory words).
Some Chinese names of measurement units contain square brackets. The characters in the square brackets are retained as the full name, and the characters in the square brackets are omitted to form the abbreviation. The characters in the square brackets can be omitted without causing confusion or misunderstanding. E.2.5 Conversion of national numbers and remarks
When necessary, it is used to convert other units into SI values ​​and other instructions. If the value in this column is accurate, the words "(accurate value)" are added after the value.
E.2.6 Indication symbols
Symbols for measurement units. The symbols used in this standard are internationally accepted symbols. E.2.7 General code
Codes for measurement units expressed in a..3. 6.2.8 Cross-reference numbers
Used for checking the order of the units in Appendix A, Appendix Book and Appendix I code table. E-2.9 The measurement units marked with * in the code table are the legal measurement units of my country as specified in GB3102. The names of the quantities, the names of the measurement units and the symbols are consistent with GB3102 (the symbols of public items adopt the international symbol ba). 6-3 Composition of the code table in Appendix B
Appendix B is a code table arranged according to the English names of the measurement units. The columns include the name of the measurement unit, the symbol, the general code, the level/category, the use mark, and the cross-reference number. The content of each column is consistent with the content of the corresponding column in Appendix A. 6.4 Composition of the code table in Appendix C
Appendix C is a code table arranged according to the general code of the measurement unit. The columns include the general code, the name of the measurement unit, the level/category, the use mark, the existing code, and the cross-reference number. The existing code column has four parts: the 3-digit code of the first edition of UN/ECE Recommendation No. 20; the 3-letter code of the first edition of UN/ECE Recommendation No. 20; the 2-letter/digital code of GB/116472; the 2-letter code of the American National Standards Institute Standard 355 Measurement Units (ANSI ASC X12T-355). 7 Maintenance Rules
7.1 The provided measurement unit code table is intended for easy maintenance, coordination and simplification. 7.2 This standard is maintained by the national standardization administrative department. If it is necessary to revise the code table of this standard: the update request should first be submitted to the national standardization administrative department, and then submitted to the international maintenance organization of this standard after review. 7.3 When a unit of measurement is deleted from the Codes: table, the generic code assigned to it will no longer be assigned to other units of measurement. 392
