+AMD1:2025 CSV 家用和类似用途电器的安全 第2-49部分：商用食品和餐具保温电器的特殊要求

[中文适用范围]： IEC 60335-2-49:2021+AMD1:2025 CSV规定了用于保持食物和餐具温暖的电动商用电器的安全要求，其额定电压单相电器连接在一相与中性线之间时不超过250 V，其他电器不超过480 V。本标准涵盖的电器示例包括：带或不带加热顶部的热柜、加热顶部、加热展示柜、加热餐具分配器、加热餐桌和辐射加热器。这些电器不用于家庭及类似用途，而是用于商业用途、食品加工，也用于公共场所，如餐厅、食堂、医院的厨房，以及面包店、肉铺等商业场所。利用其他能源形式的电器的电气部分也属于本标准范围。在可行的情况下，本标准处理了此类电器可能带来的共同危险。需要注意的是：– 用于车辆、船舶或飞机上的电器可能需要额外要求；– 在许多国家，国家卫生部门、劳动保护部门、供水部门及相关机构可能对电器有额外要求；– 在许多国家，对压力电器有额外要求。本标准不适用于：– 专为工业用途设计的电器；– 用于特殊环境（如腐蚀性或爆炸性环境，如粉尘、蒸汽或气体）的电器；– 用于食品连续批量生产的电器；– 商用电动水浴锅（IEC 60335-2-50）；– 电池供电的电器；– 按照IEC 60335-2-12标准覆盖的用于家庭用途的加热板及类似电器，由非专业人员在以下环境中使用：商店、办公室及其他工作场所的员工厨房区域，农舍、酒店、旅馆及其他住宅类型环境，以及旅馆式环境。本第五版取消并替代了2002年发布的第四版、2008年的修正案1和2017年的修正案2。本版为技术修订版。相比前一版，本版包含以下重大技术变更：a) 文本已与IEC 60335-1:2020对齐；b) 引入了用于公共场所的电器的要求，包括外部可接触表面温度（第1条、7.12、11.8、表102）；c) 排除了电池供电的电器（第1条）；d) 明确了适用于非专业人员使用的电器的适用标准（第1条、7.12）；e) 将清洁说明从7.12.1移至7.12；f) 将24.101移至22.106；g) 将IEC 60335-2-49的文本与其他IEC/TC61/MT32标准协调一致；h) 一些注释已转换为规范性文本，进行了修改或删除（第1条、7.1、7.15、11.3、11.7、15.2、19.2、22.101、23.3）；i) 增加了输入电流测量的额外要求；j) 明确了15.1.1中的测试程序；k) 明确了20.1和23.3中的测试条件；l) 明确了25.3中的要求。第2部分应与IEC 60335-1的最新版及其修正案一起使用，除非该版本排除了其使用；在该版本排除其使用的情况下，则使用最新未排除其使用的版本。该标准的第2部分是基于该标准的第六版（2020年）制定的。 [外文原描述]： IEC 60335-2-49:2021+AMD1:2025 CSV deals with the safety of electrically operated commercial appliances for keeping food and crockery warm, 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. Examples of appliances that are within the scope of this standard are: – hot cupboards, with or without heated tops; – heated tops; – heated display cases; – heated crockery dispensers; – heated tables; – radiant heaters. These appliances are not intended for household and similar purposes. They are used for commercial purposes, 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; – in many countries, additional requirements are specified for pressure appliances. 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; – commercial electric bains-marie (IEC 60335-2-50); – battery-operated appliances; – warming plates and similar appliances for household use covered by IEC 60335-2-12 used in the following environments by laymen: staff kitchen areas in shops, offices and other working environments, farm houses, 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 1:2008 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) 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); c) exclusion of battery-operated appliances (Clause 1); d) clarification of applicable standard for appliances for use by laymen (Clause 1, 7.12); e) relocation of cleaning instructions from 7.12.1 to 7.12; f) relocation of 24.101 to 22.106; g) conciliation of the text of IEC 60335-2-49 with other standards under IEC/TC61/MT32; h) some notes have been converted to normative text, modified or deleted (Clause 1, 7.1, 7.15, 11.3, 11.7, 15.2, 19.2, 22.101, 23.3); i) additional requirements for measurement of input current; j) clarification of the testing procedure in 15.1.1; k) clarification of the test conditions in 20.1 and 23.3; l) clarifications of the requirements in 25.3. 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.
