+AMD1:2025 CSV 家用和类似用途电器 - 安全 - 第2-50部分：商用电动保温餐台的特殊要求

[中文适用范围]： IEC 60335-2-50:2021+AMD1:2025 CSV 规定了电气驱动商业 Bain-marie（一种用于加热食物的设备）的安全要求。单相设备的额定电压不超过 250 V（连接在一相与中性线之间），其他设备的额定电压不超过 480 V。这些设备不用于家庭和类似用途，而是用于商业食品加工，包括对公众开放的场所，如餐馆、食堂、医院和面包店、肉铺等商业场所。使用其他能源形式的设备的电气部分也属于本标准的适用范围。在可能的范围内，本标准处理此类设备常见的危险。需要注意的是：- 用于车辆、船舶或飞机上的设备可能需要额外要求；- 许多国家由国家卫生当局、劳动保护当局、国家供水当局等规定了额外要求；- 用于户外的设备可能需要额外要求。本标准不适用于：- 专为工业用途设计的设备；- 用于存在特殊条件（如腐蚀性或爆炸性环境，如粉尘、蒸气或气体）的设备；- 用于连续大规模食品生产的设备；- 电池驱动的设备；- 由 IEC 60335-2-15 覆盖的用于家庭用途的液体加热设备，并且在以下由非专业人员使用的环境中使用：• 商店、办公室及其他工作环境中的员工厨房区域；• 农舍；• 酒店、汽车旅馆及其他居住类型环境中的客户；• 旅馆式环境。本第五版取消并替代了 2002 年发布的第四版、2007 年发布的修正案 1 和 2017 年发布的修正案 2。本版属于技术修订版。与上一版相比，本版包括以下重大技术变更：a) 文本已与 IEC 60335-1:2020 对齐；b) 一些注释已转换为规范性文本、修改或删除（第 1 章、7.15、10.1、11.7、16.2、20.1、20.101、21.101、22.101、23.3、27.2）；c) 对一些测试规范进行了澄清（7.102、9.101、11.4、15.1.1、15.2、19.1、20.1）；d) 引入了在对公众开放的区域使用的设备的要求，包括外部可接触表面的温度（第 1 章、7.12、11.8、表 102）；e) 对由非专业人员使用的设备适用的标准进行了澄清（第 1 章、7.12）；f) 排除电池驱动的设备；g) 将清洁说明从 7.12.1 移至 7.12；h) 将 24.101 移至 22.108；i) 将 IEC 60335-2-50 的文本与 IEC/TC61/MT32 下的其他标准相协调。本第 2 部分应与 IEC 60335-1 的最新版及其修正案结合使用，除非该版本排除了本标准的使用；在该情况下，使用不排除本标准的最新版。本标准建立在该标准第六版（2020）的基础上。 [外文原描述]： IEC 60335-2-50:2021+AMD1:2025 CSV deals with the safety of electrically operated commercial bains-marie, 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. These appliances are not intended for household and similar purposes. They are used for commercial processing of food, also in areas open to the public, for example in kitchens of restaurants, canteens, hospitals and in commercial enterprises such as bakeries and butcheries. The electrical part of appliances making use of other forms of energy is also within the scope of this standard. As far as is practicable, this standard deals with the common hazards presented by these types of appliances. Attention is drawn to the fact that - for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements can be necessary; - in many countries additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar authorities; - for appliances intended to be used outdoors, additional requirements can be necessary. This standard does not apply to - appliances designed exclusively for industrial purposes; - 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); - appliances for continuous mass production of food; - battery-operated appliances; - appliances for heating liquids for household use covered by IEC 60335-2-15 and used in the following environments by laymen: • staff kitchen areas in shops, offices and other working environments; • farm houses; • by clients in hotels, motels and other residential type environments; • bed and breakfast type environments. This fifth edition cancels and replaces the fourth edition published in 2002, Amendment 1: 2007 and Amendment 2:2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the text has been aligned with IEC 60335-1:2020; b) some notes have been converted to normative text, modified or deleted (Clause 1, 7.15, 10.1, 11.7, 16.2, 20.1, 20.101, 21.101, 22.101, 23.3, 27.2); c) clarifications to some test specifications have been made (7.102, 9.101, 11.4, 15.1.1, 15.2, 19.1, 20.1); d) introduction of requirements for appliances intended for use in areas open to the public, including external accessible surface temperatures (Clause 1, 7.12, 11.8, Table 102); e) clarification of applicable standard for appliances for use by laymen (Clause 1, 7.12); f) exclusion of battery-operated appliances; g) relocation of cleaning instructions from 7.12.1 to 7.12; h) relocation of 24.101 to 22.108; i) conciliation of the text of IEC 60335-2-50 with other standards under IEC/TC61/MT32. 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.
