This standard specifies the rules for the compilation of urban construction and construction industry product models. This standard applies to the compilation of product models in the urban construction and construction industry. 2 Basic provisions
CJ/T3035-1995
2.1 The urban construction and construction industry product model (hereinafter referred to as the product model) consists of four parts: name code, characteristic code, main parameter code and modification serial number, arranged in the order specified in Article 3.1. 2.2 Letters and numbers that can represent the characteristics of the product should be selected as characters in the product model. Note: Each letter, each number, and each symbol is regarded as a character. 2.3 The name code and modification serial number in the product model are expressed in uppercase Latin letters; the characteristic code is expressed in uppercase Latin letters or uppercase Arabic numerals, and the main parameter code is expressed in uppercase Arabic numerals. The Latin letters I, O and X shall not be used in the product model. 2.4 The Latin letters representing the name code and characteristic code in the product model should be the first or second letter of the Chinese phonetic character with the corresponding meaning.
2.5 In the product model, a separator "" should be added between the name code and the characteristic code, and no separator should be added between other components. 2.6 The total number of characters in the product model shall not exceed 16. 3 Product model compilation

3.2.2 The letters of the name code represent the main name, variety, type or the category, group or type to which the product belongs, or only represent part of the elements.
3.2.3 The name code should be adopted in accordance with the provisions of the current product classification and code standards of each industry. 3.3 Characteristic Code
3.3.1 The characteristic code shall not exceed two Latin letters or Arabic numerals. 3.3.2 The characteristic code represents the material, structure, process or precision of the product, but does not include the characteristics that have been included in the name code. 3.3.3 When a certain characteristic of a product is a number or ordinal number, its characteristic code can be replaced by the Latin letters A, B, C. instead of the Arabic numerals 1, 2, 3.****.
When the characteristic code is directly expressed by Arabic numerals, its position shall not be adjacent to the main parameter code. If necessary, it can be moved before or in the name code.
3.3.4 When the total number of characters in the name code and the characteristic code does not exceed three and there is no confusion, the separator before the characteristic code can be omitted. 3.3.5 If it is not necessary, the characteristic code and its separator may not be listed in the product model. 3.4 Main parameter code
3.4.1 One product can choose one or more main parameters. 3.4.2 When there are two or more main parameters, the main parameters with the same measurement unit are connected by the connector "×", and the main parameters with different measurement units are connected by the connector "_". When there is no confusion, "×" can be omitted. 3.4.3 When determining the value of the main parameter, the legal measurement unit of the People's Republic of China should be used. 3.4.4 The main parameter code can be expressed by the actual value of the main parameter of the product, or by 10 (n=-3, -2, -1, 1, 2, 3) multiples of the main parameter value.
3.4.5 When the number of main parameters is too large, a representative Arabic numeral specified in the product standard may be used to represent a group of main parameters of the product.
3.5 Modification serial number
3.5.1 According to the modification design sequence of the product, the modification serial number is represented by Latin letters A, B, C... in sequence. 3.5.2 The first design product does not have a modification serial number. 4 Additional provisions
For imported products produced in China according to foreign standards, the original product model can be retained. Engineering Construction Standard Full-text Information System
