DIN EN 60335-2-68:2015-02

This standard contains text of the international publication IEC 60335-2-68:2012 which has been adopted by CENELEC as a European Standard including agreed joint modifications. The standard has been substantially revised and updated according to the state of the art. Particularly, Clauses 15, 22 und 25 have been modified. The Annexes AA 'Emission of acoustical noise' and BB 'Emission of vibration' have been added. This European 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. 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. The above mentioned spray extraction machines are used for applications other than normal household purposes, for example in hotels, schools, hospitals, factories, shops, supermarkets, offices and banks as well as rental services. The responsible committee is DKE/UK 511.14 "Gewerbliche Bodenreinigungsmaschinen" ("Floor cleaning machines for commercial use") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
