This part specifies the structural type, technical requirements, test methods, inspection rules, marking and packaging requirements for engineering plastic fans for small and medium-sized asynchronous motors. This section applies to the basic series of plastic fans for small and medium-sized asynchronous motors (frame sizes 63 to 355). It also applies to plastic fans for non-sparking small and medium-sized asynchronous motors and other general-purpose projects for small and medium-sized asynchronous motors that have no special requirements for fans. Plastic fan (hereinafter referred to as fan).
