IEC 60335-2-110:2013 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. Appliances covered by this standard incorporate an open-ended applicator (as example an overview is given in Figure 103) 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 (an example is given in Figure 106) - with large area contacting applicator, typically for drying of floors, walls or ceilings (examples are given in Figure 104 and Figure 105) - with small area contacting applicator, typically for paint removal and spot-heating (an example is given in Figure 107). Key words: commercial microwave appliance, insertion applicator, contacting applicator
