BS EN 60079-6:2015 specifies the requirements for the design, construction, testing and
marking of Ex Equipment and Ex Components with type of protection liquid immersion "o"
intended for use in explosive gas atmospheres.Ex Equipment and Ex Components of type of protection liquid immersion "o" are either:Level of Protection "ob" (EPL "Mb" or "Gb")Level of Protection "oc" (EPL "Gc")For Level of Protection "ob", this standard applies where the rated voltage does not exceed
11 kV r.m.s. a.c. or d.c.For Level of Protection "oc", this standard applies where the rated voltage does not exceed
15 kV r.m.s. a.c. or d.c.NOTE Requirements for higher voltages are under consideration.This standard supplements and modifies the general requirements of IEC 60079-0. Where a
requirement of this standard conflicts with a requirement of IEC 60079-0, the requirement of
this standard takes precedence.Cross References:IEC 60079-0IEC 60156IEC 60247IEC 60296IEC 60529IEC 60814IEC 60836IEC 61099IEC 61125IEC 62021-1IEC 62535ISO 2592ISO 2719ISO 3016ISO 3104IEC 60050-421IEC 60050-441IEC 60079IEC 62770EN 50495EN 60079-0EN 60156EN 60247EN 60296EN 60814EN 60836EN 61099EN 61125EN 62021-1EN 62535EN ISO 2592EN ISO 2719EN ISO 3104EN 60079EN 62770All current amendments available at time of purchase are included with the purchase of this document.
