+AMD1:2025 CSV 家用和类似用途电器的安全 第2-119部分：商用真空包装设备的特殊要求

[中文适用范围]： IEC 60335-2-119:2021+AMD:2025 CSV 处理使用真空条件进行食品保存的商用电器的安全性，其额定电压不超过单相电器的250V和其它电器的480V。 这些电器不用于家庭及其他类似用途。它们用于商业食品保鲜区域，这些区域不对公众开放，例如餐馆、食堂、医院以及糕点店和肉铺等商业企业。 本标准涵盖以下设备： – 室内真空包装机； – 真空包装机。 这些设备可能具有封膜功能。 本标准还处理电器的卫生方面问题。 尽可能地，本标准处理用户在使用过程中遇到的常见危害。然而，一般来说，它不考虑儿童玩耍该设备的情况。 请注意以下几点： – 对于旨在用于车辆、船舶或飞机上的设备，可能需要额外的要求； – 在许多国家，对包含压力容器的电器另有规定； – 在许多国家，卫生当局、负责劳动保护的国家机关、水务供应机构以及其他类似机构制定了额外要求。 本标准不适用于： – 使用惰性气体在真空室中注入氧气含量超过21%的操作设备； – 用于特殊条件下的场所（如腐蚀性或爆炸性气氛存在）的操作设备； – 家用和类似用途的真空包装机（IEC 60335-2-45）； – 电池操作的电器。 本第二部分应与最新版IEC 60335-1及其修正案一起使用，除非该版本禁止这样做；在这种情况下，不禁止使用的最新版本将被采用。它是基于该标准第六版（2020年）建立的。 [外文原描述]： IEC 60335-2-119:2021+AMD:2025 CSV deals with the safety of commercial electric packaging appliances using vacuum conditions for food preservation, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances. These appliances are not intended for household and similar purposes. They are used for commercial preservation of food in areas not open to the public, for example in kitchens of restaurants, canteens, hospitals and in commercial enterprises such as bakeries and butcheries. Examples of appliances that are within the scope of this standard are: – chamber vacuum packaging appliances; – vacuum packaging appliances. These appliances may be provided with a film-sealing function. This standard also deals with the hygiene aspects of appliances. As far as is practicable, this standard deals with the common hazards presented by appliances that are encountered by users. However, in general, it does not consider young children playing with the appliance. Attention is drawn to the fact that: – for appliances intended to be used in vehicles or onboard ships or aircraft, additional requirements may be necessary; – in many countries, additional requirements for appliances incorporating pressure vessels are specified; – 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. This standard does not apply to: – appliances which operate with injection in the vacuum chamber of inert gas with an oxygen content exceeding 21 %; – 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); – vacuum packaging appliances for household and similar use (IEC 60335-2-45); – battery-operated appliances. 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.
