scope:

This clause of Part 1 is replaced by the following. This international standard deals with the safety of microwave appliances intended for commercial use, their rated voltage being not more than 250 V for single-phase appliances connected between one phase and neutral and 480 V for other appliances. In general, this standard does not take into account - persons (including children) whose - physical, sensory or mental capabilities; or - lack of experience and knowledge prevents them from using the appliance safely without supervision or instruction; - children playing with the appliance. Appliances covered by this standard incorporate an open-ended applicator for treatment of the load. They are divided into three types: - with insertion applicator, typically for moisture removal by insertion into holes in floors, walls or ceilings; - with large area contacting applicator, typically for drying of floors, walls or ceilings; - with small area contacting applicator, typically for paint removal and spot-heating. NOTE 101 Appliances with insertion applicator and with large area contacting applicator are portable appliances. Appliances with small area contacting applicator are handheld appliances. NOTE 102 Appliances that use non-electrical energy are within the scope of this standard. The microwave-related portion is considered motor-operated. NOTE 103 Attention is drawn to the fact that - these appliances may radiate microwave energy outside a restricted area where they are used. The additional requirements specified by national authorities responsible for the protection for non-ionising radiation that the power flux density may not exceed 10 W/m2, averaged over any time period of 6 minutes, outside this restricted area is taken into consideration in this standard; - these appliances are intended to exclusively treat the load in normal operation, i.e. this standard does not apply to appliances or systems employing free space microwave propagation; - for appliances intended to be used in tropical countries, special requirements may be necessary; - in many countries, additional requirements are specified by the national health authorities, and national authorities responsible for the protection of labour and for non-ionising radiation protection. NOTE 104 This standard does not apply to - household microwave ovens including combination microwave ovens (IEC 60335-2-25); - commercial microwave ovens with a cavity door, commercial combination microwave ovens with a cavity door and commercial microwave ovens without a cavity door and with transportation means (IEC 60335-2-90); - industrial microwave heating equipment (IEC 60519-6); - appliances for medical purposes (IEC 60601-1, Medical electrical equipment); - appliances and equipment for laboratory use (series of IEC 61010); - appliances intended to be used in locations where special conditions 224 prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas). NOTE 105 Some of the specifications and tests in this standard may not be applicable for other than 2 450 MHz appliances.
