Basic rules of product code:
Constitution of main identifier code:
 
   
   
     
Code of product’s basic feature: describing product’s additional features, different products
have different features.
Extended identification code of software products:
Because of the particularity of software, the code of basic feature cannot be expressed; basic
feature code of software is empty. Extended identifier code has no specific meaning, and is
only the producing label of software. Technology department is required to notify other
departments the main functions of each labeled software and make detailed records.
Especial explanations
If new product’s code cannot be found in above table, we can add identifier code in
accordance with basic coding rules in chapter one, but the code must accord with the rules
and should be recorded.
