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涉及商业用途微波设备的安全性，其额定电压不超过单相设备连接一相与中性线之间的250V，其他设备为480V。 本标准通常不考虑以下情况： - 由于身体、感官或精神能力不足，或缺乏经验和知识而无法在没有监督或指导的情况下安全使用设备的人员（包括儿童）； - 儿童玩耍设备。 本标准尽可能处理这些类型设备带来的常见危险。 本标准涵盖的设备包括用于处理负载的开放式应用器（如图103所示）。它们分为三种类型： - 插入式应用器，通常用于通过插入地板、墙壁或天花板的孔洞进行除湿（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，通常用于油漆去除和局部加热（如图107所示）。 微波设备使用300MHz至30GHz之间的ISM频段中的一个或多个频段，向外部负载提供能量，使其加热，从而产生干燥、水分传输（可能导致蒸汽形成、分解或化学改性、熔化或终止细菌或真菌等生物体的过程）。 注意： - 这些设备可能会在限制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功率通量密度限制为10 W/m²，任何6分钟时间段的平均值； - 这些设备在正常操作中仅用于处理负载，本标准不适用于采用自由空间微波传播的设备或系统； - 用于热带国家的设备可能需要特殊要求； - 许多国家的国家卫生机构和劳动保护机构可能规定了额外要求。 本标准不适用于： - 家用微波炉，包括组合微波炉（IEC 60335-2-25）； - 带腔门的商用微波炉、带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）； - 医疗用途设备（IEC 60601-1）； - 实验室用设备和器具（IEC 61010系列）； - 用于特殊条件（如腐蚀性或爆炸性环境）的设备。 [外文原描述]： IEC 60335-2-110:2024 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. 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.
