It also applies to industrial and commercial steam cleaners even if the pressure is less than 2,5 MPa. It is also applicable to appliances making use of other forms of energy for the motor, but it is necessary that their influence is taken into consideration.

Applicable to the safety of electrical portable, motor-operated spray extraction appliances and electrical attachments intended for industrial and commercial use, their rated voltage being not more than 250 V for single-phase and 480 V for other appliances. These appliances employ water-based cleaning agents and are used for cleaning fabrics, upholstery, carpets, floor coverings or hard surfaces.

Deals with the safety of mains or battery supplied portable combined machines, with or without a built-in battery charger, having a chassis with or without traction drive, intended for commercial and industrial use indoors or outdoors for dry or wet treatment of hard floors or of floors with carpeting, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances.

Deals with particular requirements for safety of electrical motor-operated floor polishing (including waxing and buffing), scrubbing and grinding, scarifying and carpet shampooing appliances primarily designed for industrial and commercial use, including appliances incorporating wet and/or dry suction which are not within the scope of IEC 60335-2-10 and IEC 60335-2-68.

Applies to electrical motor-operated vacuum cleaners for wet suction, dry suction or wet and dry suction for industrial and commercial use with or without attachments, for example for suction to withdraw dust or the like from work benches and production machines. Also applies to machines handling hazardous dust, e.g. asbestos, or liquids for which additional national requirements apply. Also applies to appliances making use of other forms of energy for the motor.
