scope:

This standard deals with the safety of electrical portable, motor-operated extraction appliances and electrical attachments intended for industrial and commercial use, their rated voltage being not more than 250 V for single-phase appliances 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. NOTE Commercial uses are for example for use in hotels, schools, hospitals, factories, shops and offices for other than normal housekeeping purposes. Machines with or without electrical heating elements and with or without attachments are within the scope of this standard. This standard covers appliances in which the pressure of the cleaning agent is positive and not more than 2,5 MPa, or in which the product of the pressure (in MPa) and the flow of cleaning agent (in litres per minute) does not exceed 100, and in which the temperature of the cleaning agent at the spray nozzle outlet does not exceed 85 ºC. This standard also applies to machines handling hazardous dust such as asbestos or liquids for which additional national requirements might apply. 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.
