This clause of Part 1 is replaced by the following. This International Standard deals with the safety of electrical portable, non-self-propelled motor-operated spray extraction machines with or without attachments and with or without electrical heating elements, intended for commercial indoor use. They are not equipped with a traction drive. The following power systems are covered: - mains powered motors up to a rated voltage of 250 V for single-phase appliances and 480 V for other appliances, - battery powered motors. This standard applies to machines in which the pressure of the employed cleaning agent does not exceed 2,5 MPa, and 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 does not apply to - vacuum cleaners and water-suction cleaning appliances for household use (IEC 60335-2-2); - floor treatment machines for commercial use (IEC 60335-2-67, IEC 60335-2-72); - wet and dry vacuum cleaners, including power brush, for commercial use (IEC 60335-2-69); - hand-held and transportable motor-operated electric tools (IEC 60745 series, IEC 61029 series). - machines designed for use in corrosive or explosive environments (dust, vapour or gas); - machines designed for picking up hazardous dusts (as defined in IEC 60335-2-69), inflammable substances, or glowing particles; - machines designed to handle hazardous solvents, such as flammable or explosive liquids.
