IEC 60335-2-79:2002

Applies to high pressure cleaners having a pressure not less than 25 bars and not more than 250 bars with an input to the drive for the high pressure pump not exceeding 10 kW. It also applies to steam cleaners having a usable volume of the water container equal to or greater than 1,5 litres even if the pressure is less than 25 bars. Also applies to fixed appliances within the limits of the previous paragraph. 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.

IEC 60335-2-79:2012(E) 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 x 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 powered motors, - internal combustion engines and - hydraulic or pneumatic motors. This third edition cancels and replaces the second edition published in 2002 and its Amendments 1 (2004) and 2 (2007). It constitutes a technical revision. The principal changes in this edition as compared with the second edition of IEC 60335-2-79 are as follows (minor changes are not listed): - the scope has been revised editorially to avoid misunderstandings; - terms and definitions has been revised with regard to the requirements revised; - the standard has been revised in general and updated regarding state-of-the-art, as far as necessary, in particular some changes have been made to Clauses 15, 22, and 25; - a new Annex CC 'Emission of acoustical noise' was added; - a new Annex DD 'Emission of vibration' was added and - a new Annex EE with a model test report for vibration emission was added. This publication is to be read in conjunction with IEC 60335-1:2010.
