EN 60335-2-68:2009

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.NOTE Z101 Commercial use of spray extraction machines is for example their use in hotels, schools, hospitals, factories, shops and offices for other than normal housekeeping purposes and rental services for those machines.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 ºC.NOTE Z102 Attention is drawn to the fact that in many countries additional requirements on the safe use of the equipment covered may be specified by the national health authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar authorities. This standard does not apply to –machines designed to be part of a production process;–wet and dry vacuum cleaners as covered by IEC 60335-2-69;–machines designed for picking up hazardous dusts, inflammable substances, or aflame particles;–floor treatment machines for commercial use;NOTE Z103 IEC 60335-2-67 covers floor cleaning and floor treatment machines for industrial and commercial use. IEC 60335-2-72 covers automatic floor treatment machines for industrial and commercial use.–machines designed for use in corrosive or explosive environments (dust, vapour or gas);–hand-held appliances;–hand-held and transportable motor-operated electric tools.NOTE Z104 The IEC 60745 series covers hand-held motor-operated electric tools; the IEC 61029 series covers transportable motor-operated electric tools.
