IEC/SC 61B - IEC_SC_61B

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

IEC 60335-2-90:2015(E) deals with - the safety of microwave ovens with a cavity door 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; - the safety of combination microwave ovens with a cavity door, the requirements for which are contained in Annex AA; - the safety of microwave ovens without a cavity door and with transportation means that are intended for commercial use only, for the heating of food and beverages, the requirements for which are contained in Annex BB. Microwave ovens covered by Annex BB have transportation means for moving the load through the microwave oven. Requirements for tunnel microwave ovens and several types of microwave vending machines are covered. This standard also deals with microwave ovens intended to be used on board ships, for which Annex EE is applicable. In general, this standard does not take into account the use of appliances by young children or infirm persons without supervision or children playing with the appliance. This international standard does not take into account the use of a microwave oven without a cavity door and with transportation means by ordinary persons except in the vicinity of entrance and exit ports. This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its amendments. It was established on the basis of the fifth edition (2010) of that standard. This fourth edition cancels and replaces the third edition published in 2006 including its Amendment 1 (2010) and Amendment 2 (2014). It constitutes a technical revision. The principal changes with respect to the previous edition are as follows (minor and editorial changes are not listed): - a statement in 7.12 is required for appliances intended to be used on commercial road vehicles; - a statement in 7.12 is required concerning cleaning of the appliance with a water jet; - the replacement of 22.103, 22.104 and 22.105 allows interlock systems with at least one concealed door interlock as well as alternative interlock systems without concealed door interlock; - requirements are added for appliances for installation in commercial road vehicles; - an annex is added dealing with routine tests. The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the recommendation of the committee that the content of this standard be adopted for implementation nationally not earlier than 12 months or later than 36 months from the date of its publication.

61B/278/CDV merged into IEC 60335-2-25:2002/A1:2005 (harmonized as pr=15957)

This European Standard deals with the safety of microwave ovens for household and similar use, their rated voltage being not more than 250 V. This European Standard also deals with combination microwave ovens, for which Annex AA is applicable. This standard also deals with microwave ovens intended to be used on board ships, for which Annex BB is applicable. As far as is practicable, this European Standard deals with the common hazards presented by appliances that are encountered by all persons in household and similar environments. However, in general, it does not take into account: • children playing with the appliance; • the use of the appliance by very young children; • the use of the appliance by young children without supervision. It is recognized that very vulnerable people may have needs beyond the level addressed in this European Standard. NOTE Z101 Examples of appliance for household environment are appliances for typical housekeeping functions used in the household environment that may also be used by non expert users for typical housekeeping functions: – in shops and other similar working environments; – in farm houses; – by clients in hotels, motels and other residential type environments; – in bed and breakfast type environments. NOTE Z102 Household environments include the dwelling and its associated buildings, the garden, etc. As far as is practicable, this standard deals with the common hazards presented by appliances that are encountered by all persons in and around the home. However, in general, it 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. NOTE Z103 Attention is drawn to the fact that - for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be necessary; - in many countries, additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour and similar authorities. NOTE Z104 This standard does not apply to - commercial microwave ovens (EN 60335-2-90) - industrial microwave heating equipment (EN 60519-6) - appliances for medical purposes (EN 60601) - 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).

IEC 60335-2-90-A1:2010 Amendment 1 NOTE The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the recommendation of the committee that the content of this publication be adopted for implementation nationally not earlier than 12 months or later than 36 months from the date of publication.

Corrigendum to EN issued November 2003

Deals with the safety of commercial microwave ovens. These ovens incorporate a door for user access to the cavity. The rated voltage is less than 250 V. for single phase appliances and 480 V. for other appliances. The oven may be built into a vending machine (see also EN 60335-2-75). The oven may also incorporate conventional heating means (see also EN 60335-2-36 and EN 60335-2-42). For household microwave ovens, see EN 60335-2-25. For industrial microwave heating equipment, see EN 60519-6. For appliances for medical purposes, see EN 60601.
