[中文适用范围]： IEC 60335的本部分涉及使用真空条件保存食品的商业电气包装器具的安全性，其额定电压对于单相器具不超过250V，对于其他器具不超过480V。这些设备不适用于 [外文原描述]： 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.
