1 прибор класса II
прибор класса II
Прибор, в котором защита от поражения электрическим током обеспечивается не только основной изоляцией, но в котором предусмотрены дополнительные меры безопасности, такие как двойная или усиленная изоляция, причем не предусмотрено защитное заземление, а условия установки не являются дополнительной гарантией.
Примечания:
1. Такие приборы могут быть отнесены к одному из следующих типов:
a) прибор, имеющий прочный и практически сплошной кожух из изоляционного материала, который покрывает все металлические части, за исключением небольших деталей, таких как заводская табличка, винты и заклепки, которые изолированы от токоведущих частей изоляцией, по крайней мере эквивалентной усиленной изоляции;
такой прибор называют прибором класса II с изолирующим кожухом;
b) прибор, имеющий практически сплошной металлический кожух, в котором повсюду применена двойная или усиленная изоляция; такой прибор называют прибором класса II с металлическим кожухом;
c) прибор, являющийся комбинацией типов, указанных в перечислениях а) и b).
2. Кожух прибора класса II с изолирующим кожухом может образовывать часть или всю дополнительную или усиленную изоляцию.
3. Если прибор, имеющий повсюду двойную или усиленную изоляцию, снабжен заземляющим зажимом или заземляющим контактом, то его относят к приборам класса 0 или 0I.

class II appliance
appliance in which protection against electric shock does not rely on basic insulation only but in which additional safety precautions are provided, such as double insulation or reinforced insulation, there being no provision for protective earthing or reliance upon installation conditions
NOTE 1 - Such an appliance may be of one of the following types:
– an appliance having a durable and substantially continuous enclosure of insulating material which envelops all metal parts, with the exception of small parts, such as nameplates, screws and rivets, which are isolated from live parts by insulation at least equivalent to reinforced insulation; such an appliance is called an insulation-encased class II appliance;
– an appliance having a substantially continuous metal enclosure, in which double insulation or reinforced insulation is used throughout; such an appliance is called a metal-encased class II appliance;
– an appliance which is a combination of an insulation-encased class II appliance and a metal-encased class II appliance.
NOTE 2 - The enclosure of an insulation-encased class II appliance may form a part or the whole of the supplementary insulation or of the reinforced insulation.
NOTE 3 - If an appliance with double insulation or reinforced insulation throughout has provision for earthing, it is considered to be a class I appliance or a class 0I appliance.

appareil de la classe II
appareil dans lequel la protection contre les chocs électriques ne repose pas uniquement sur l'isolation principale mais dans lequel ont été prises des mesures supplémentaires de sécurité, telles que la double isolation ou l'isolation renforcée, ces mesures ne comportant pas de moyen de mise à la terre de protection et ne dépendant pas des conditions d'installation
NOTE 1 - Un tel appareil peut être de l'un des types suivants:
– un appareil ayant une enveloppe durable et pratiquement continue en matière isolante enfermant toutes les parties métalliques, à l'exception de petites pièces telles que plaques signalétiques, vis et rivets, qui sont séparées des parties actives par une isolation au moins équivalente à l'isolation renforcée; un tel appareil est appelé appareil de la classe II à enveloppe isolante;
– un appareil ayant une enveloppe métallique pratiquement continue, dans lequel la double isolation ou l'isolation renforcée est partout utilisée; un tel appareil est appelé appareil de la classe II à enveloppe métallique;
– un appareil qui est la combinaison d’un appareil de la classe II à enveloppe isolante et d’un appareil de la classe II à enveloppe métallique.
NOTE 2 - L'enveloppe d'un appareil de la classe II à enveloppe isolante peut former tout ou partie de l'isolation supplémentaire ou de l'isolation renforcée.
NOTE 3 - Si un appareil ayant en toutes ses parties une double isolation ou une isolation renforcée comporte des dispositions en vue de la mise à la terre, il est considéré comme étant un appareil de la classe I ou un appareil de la classe 0I.
