This standard applies to portable electrical motor-operated spray extraction appliances and electrical attachments employing water-based cleaning agents for cleaning fabrics, upholstery, carpets, floor coverings or hard surfaces, intended for industrial and commercial use.

Commercial uses are for example for use in hotels, schools, hospitals, factories, shops and offices, for other than normal housekeeping purposes, and in the rental business.

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 25 bars, or in which the product of the pressure (in bars) and the flow of cleaning agent (in litres per minute) does not exceed 1000, and in which the temperature of the cleaning agent at the spray nozzle outlet does not exceed 85 degrees C.

This standard also applies to machines handling hazardous dust, e.g. asbestos, or liquids for which additional requirements 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.
