Household and similar electrical appliances - Safety - Part 2-68: Particular requirements for spray extraction appliances, for industrial and commercial use
This clause of Part 1 is replaced by the following.
This International Standard deals with 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 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
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 °C.
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.
