Scope This clause of part 1 is replaced by:

This standard deals with the safety of stationary electric circulation pumps intended for use in heating systems or in service water systems, having a rated power input not exceeding 300 W, their rated voltage is not more than 250 V for single-phase appliances and 480 V for other appliances.

Appliances not intended for normal household use, but which nevertheless may be a source of danger to the public, such as appliances intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard.
