Household and similar electrical appliances - Safety - Part 2-79: Particular requirements for high pressure cleaners and steam cleaners

IEC 60335-2-79:2016 deals with the safety of high-pressure cleaners without traction drive, intended for
household and commercial indoor or outdoor use, having a rated pressure not less than 2,5 MPa and not
exceeding 35 MPa. It also applies to steam cleaners and those parts of hot water high pressure cleaners
incorporating a steam stage which have a capacity not exceeding 100 l, a rated pressure not exceeding 2,5
MPa and a product of capacity and rated pressure not exceeding 5 MPa·l. They are not equipped with a
traction drive. The following power systems of the drive for the high pressure pump are covered:
- mains powered motors up to a rated voltage of 250 V for single-phase machines and 480 V for other
machines,
- battery-operated motors,
- internal combustion engines,
- hydraulic or pneumatic motors. This standard does not apply to:
- high pressure water jet machines having a rated pressure exceeding 35 MPa;
- steam cleaners intended for domestic use;
- hand-held and transportable motor-operated electric tools;
- appliances for medical purposes;
- agricultural sprayers;
- non-liquid, solid abrasive cleaners;
- machines designed to be part of a production process;
- machines designed for use in corrosive or explosive environments (dust, vapour or gas) or
- machines designed for use in vehicles or on board of ships or aircraft.
