家用和类似用途电器. 安全性. 第2-90部分: 商用微波炉的特殊要求

[中文适用范围]： 本国际标准涉及：商用带腔门的微波炉的安全@其额定电压对于连接在一相和中性点之间的单相器具不超过250V，对于其他器具不超过480V；带腔门的组合微波炉的安全@其要求包含在附录AA中；不带腔门且仅用于商业用途的运输工具@用于加热食品和饮料@的微波炉的安全性@其要求包含在附录BB中。附件 BB 所涵盖的微波炉具有用于将负载移动通过微波炉的运输装置。涵盖了隧道微波炉和几种类型的微波炉自动售货机的要求。本标准还涉及适用附件 EE 的船上使用的微波炉。注 101 在附录 BB@ 中，不带腔门且具有运输工具的微波炉被描述为微波炉。除非附录 BB 中另有规定，本标准的所有条款均适用于这些器具。该国际标准还考虑到普通人可以进入自动售货机的移除区域。注 102：该器具可内置于自动售货机@，在这种情况下，IEC 60335-2-75 也适用。注103 使用非电能的器具属于本标准的范围。一般来说，本标准不考虑幼儿或体弱者在没有监督的情况下使用电器； ?C 年幼的孩子玩弄该设备。本国际标准不考虑普通人在出入口附近以外的地方使用没有腔门且有交通工具的微波炉。注 104：特定微波暴露条件的基本原理以及与开放结构限制微波能量相关的措施见附件 BB。注 105 请注意，对于用于车辆、船舶或飞机的器具，可能需要附加要求； ?C 用于热带国家的器具@可能需要特殊要求； ?C 在许多国家@国家卫生当局@负责劳工保护的国家当局和类似当局规定了附加要求； ?C 在许多国家@国家当局指定了 BB.22.119.1 的附加要求。注 106 本标准不适用于 C 家用微波炉，包括组合微波炉（IEC 60335-2-25）； ?C 工业微波加热设备（IEC 60519-6）； ?C 医疗用途器具（IEC 60601）； ?C 设备用于特殊条件下的场所@，例如存在腐蚀性或爆炸性气氛（灰尘@蒸汽或气体）。 [外文原描述]： IEC 60335-2-90:2015 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.
