This standard specifies the structural type, technical requirements, test methods and inspection rules, marking, transportation and storage of engineering plastic fans for small asynchronous motors. This standard applies to the basic series of small asynchronous motors (frame sizes 63 to 355) and other general-purpose engineering plastic fans for small asynchronous motors that have no special requirements for fans.
