家用及类似用途电器 安全 第2-110部分：带有插入或接触式涂抹器的商用微波炉的特殊要求

[中文适用范围]： 本部分IEC 60335涉及商用微波设备的安全，其额定电压对于单相设备连接在一相和中性线之间的不超过250V，其他设备不超过480V。 本标准尽可能处理这些类型设备所呈现的常见危险。 本标准涵盖的设备包括一个开放式应用器（如图103所示）用于处理负载。它们分为三种类型： - 插入式应用器，通常用于通过插入地板、墙壁或天花板上的孔洞去除水分（如图106所示）； - 大面积接触式应用器，通常用于干燥地板、墙壁或天花板（如图104和图105所示）； - 小面积接触式应用器，通常用于去除油漆和局部加热（如图107所示）。 微波设备在ISM频段（300MHz至30GHz之间）使用电磁能量，向外部负载提供能量，使其加热，从而产生干燥、水分运输、蒸汽形成、分解或化学改性、熔化或终止细菌或真菌等生物的过程。 注意101：ISM频段是由ITU建立并在CISPR 11中复制的电磁频率。 注意102：食品和饮料不在本标准的负载范围内。 带有插入式应用器和大面积接触式应用器的设备是便携式设备。带有小面积接触式应用器的设备是手持设备。 使用非电能的设备也在本标准范围内。微波相关部分被视为电动操作。 微波屏障和相关泄漏测试的原理在信息性附录AA中描述。 需要注意的是： - 这些设备可以在使用区域外辐射微波能量。国家非电离辐射保护机构规定的附加要求，即在该限制区域外的功率通量密度限值为10W/m²，平均在6分钟内，本标准已考虑； - 这些设备在正常操作中仅用于处理负载，即本标准不适用于采用自由空间微波传播的设备或系统； - 对于在热带国家使用的设备，可能需要特殊要求； - 在许多国家，国家卫生机构和负责劳动保护及非电离辐射保护的国家机构规定了附加要求。 本标准不适用于： - 家用微波炉，包括组合微波炉（IEC 60335-2-25）； - 带有腔门的商用微波炉、带有腔门的商用组合微波炉以及不带腔门但带有运输装置的商用微波炉（IEC 60335-2-90）； - 工业微波加热设备（IEC 60519-6）； - 医疗用途的设备（IEC 60601-1）； - 实验室使用的设备和设备（IEC 61010系列）； - 在特殊条件下使用的设备，如存在腐蚀性或爆炸性环境（粉尘、蒸汽或气体）； 本标准中的一些规格和测试不适用于除2450MHz以外的设备。 [外文原描述]： IEC 60335-2-110:2024 EXV contains both the international standard and its extended version (EXV). This extended version of the official IEC Standard is available in English only and provides the user with a comprehensive content of the Standard. IEC 60335-2-110:2024 EXV includes the content of the references made to IEC 60335-1:2020 . 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.
