All standards will be revised, and parties using this standard should explore the possibility of using the latest version of the following standards. GB/T10067.1-1988 General Part of Basic Technical Conditions for Electric Heating Equipment 3 Definitions
This standard adopts the following definitions
According to the provisions of Chapter 3 of GB/T10067.1-1988. 4 Characters and their writing rules
4.1 Models are composed of three types of characters: letters, numbers and symbols. 4.2 Except for special circumstances, letters should generally be uppercase Chinese phonetic letters. The letters I and O shall not be used; X is only allowed to be used before or after another letter. Letters shall not be footnoted, that is, Ab, B, etc. shall not be used. 4.3 Numbers shall be Arabic numerals, and Roman numerals or other numbers shall not be used. 4.4 Symbols are only allowed to use multiplication signs (×), dashes (一) and decimal points (.) 4.5 If numbers are used to represent values, numbers with the same measurement unit shall be separated by (×), and numbers with different measurement units or different meanings shall be separated by (一).
4.6 Letters with different meanings are separated by a (-) sign (excluding the case where two or more letters represent a specific meaning). 4.7 No sign is added between letters and numbers, and no space is left. 4.8 If there are too many characters in the parameter value of the model, one or no more than two numbers can be used to represent a group of digital characters. Example: The number 1 is used to represent 600×1200×400. If the manufacturer deems it necessary, the digital character group represented by the number should be explained. 5 Series Product Models
