Abstract：
Compiles the design drawing standard based on the theoretical calculation and test methods. The standard adds contents of the non-metallic composite duct, spiral duct etc. and makes easier selection of the duct. Provides a compendious presentation of the main contents, the basic experimental test methods and the problem to be solved in the standard.
