Anotation

IEC 60335-2-110:2024 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. As far as is practicable, this standard deals with the common hazards presented by these types of appliances. 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. Microwave appliances with insertion applicator, large area contacting applicator or small area contacting applicator are using electromagnetic energy in one or several of the ISM frequency bands between 300 MHz and 30 GHz, for supplying energy to an external load which is heated so that a resulting process of drying, moisture transport which can result in forces due to formation of steam, decomposition or chemical modification, melting, or termination of organisms such as bacteria or fungus occurs. Appliances with insertion applicator and with large area contacting applicator are portable appliances. Appliances with small area contacting applicator are handheld appliances. Appliances that use non-electrical energy are within the scope of this standard. The microwave-related portion is considered motor-operated. The rationales for the microwave barrier and associated leakage tests are described in informative Annex AA. Attention is drawn to the fact that - these appliances can 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 limit of power flux density is 10 W/m2, averaged over any time period of 6 min, 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 can 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. 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); - appliances and equipment for laboratory use (IEC 61010 series); - appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas); Some of the specifications and tests in this standard are not applicable for other than 2 450 MHz appliances. This second edition cancels and replaces the first edition published in 2013 and Amendment 1:2019. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - Subclause 7.1 has been improved in clarity. - Subclauses 19.11.2 and 19.103 have been improved in clarity. - Clause 28 has been modified to add screw requirements. This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its amendments unless that edition precludes it; in that case, the latest edition that does not preclude it is used. It was established on the basis of the sixth edition (2020) of that standard. LIEC 60335-2-110:2024 traite de la securite des appareils a micro-ondes a usage commercial dont la tension assignee est inferieure ou egale a 250 V pour les appareils monophases raccordes entre un conducteur de phase et le conducteur de neutre, et a 480 V pour les autres appareils. Dans la mesure du possible, la presente norme traite des dangers courants que presentent ces types dappareils. Les appareils couverts par la presente norme comportent un applicateur ouvert destine au traitement de la charge. Ils sont classes en trois types: - les appareils avec applicateur par insertion, generalement destines a lelimination de lhumidite par insertion dans des trous au plancher, au mur ou au plafond; - les appareils avec applicateur par contact de grande surface, generalement destines au sechage de planchers, murs ou plafonds; - les appareils avec applicateur par contact de petite surface, generalement destines au decapage de peinture et au chauffage localise. Les appareils a micro-ondes avec applicateur par insertion, applicateur par contact de grande surface ou applicateur par contact de petite surface utilisent lenergie electromagnetique sur une ou plusieurs bandes de frequences ISM comprises entre 300 MHz et 30 GHz pour fournir de lenergie a une charge externe qui est chauffee de maniere a assurer le sechage, ou le transport dhumidite peut conduire a la generation de forces causee par la formation de vapeur, la decomposition ou la modification chimique, la fusion ou la destruction dorganismes tels que les bacteries ou les champignons. Les appareils avec applicateur par insertion et avec applicateur par contact de grande surface sont des appareils mobiles. Les appareils avec applicateur par contact de petite surface sont des appareils portatifs. Les appareils qui utilisent une energie non electrique relevent du domaine dapplication de la presente norme. La section a micro-ondes est
