IEC 60335-2-119:2021涉及使用真空条件保存食品的商用电气包装电器的安全性，单相电器的额定电压不超过250 V，其他电器的额定电压不超过480 V。 这些电器不用于家用和类似用途。它们用于不对公众开放的区域的食品的商业保存，例如在餐馆、食堂、医院的厨房和商业企业如面包店和肉店。 本标准范围内的设备示例包括: -腔室真空包装器具； -真空包装器具。 这些器具可以具有薄膜密封功能。 该标准还涉及器具的卫生方面。 在可行的情况下，本标准涉及用户遇到的电器带来的常见危害。然而，一般来说，它不考虑幼儿玩该设备。 提请注意以下事实: -对于拟用于车辆或船舶或飞机上的器具，可能需要附加要求； -在许多国家，对装有压力容器的器具规定了额外的要求； -在许多国家，国家卫生当局、负责劳动保护的国家当局、国家供水当局和类似当局规定了额外的要求。 本标准不适用于: -在真空室中注入氧含量超过21%的惰性气体操作的设备； -拟在有特殊条件的地方使用的器具，例如存在腐蚀性或爆炸性气氛（灰尘、蒸汽或气体）；-家用和类似用途的真空包装器具(IEC 60335-2-45)； -电池供电的电器。 本第2部分应与最新版本的IEC 60335-1及其修订一起使用，除非该版本排除了本第2部分；在这种情况下，使用不排除它的最新版本。它是在该标准第六版（2020年）的基础上建立的。

IEC 60335-2-119:2021 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.
