BS IEC 61892-7:2007 pdf free.Mobile and fixed offshore units – Electrical installations – Part7:Hazardous areas.
IEC 61892 forms a series of International Standards intended to ensure safety in the design selection, installation, maintenance and use of electrical equipment for the generation storage, distribution and utilization of electrical energy for all purposes in offshore units which are used for the exploration or production of petroleum resources.
This part of IEC 61892 also incorporates and co-ordinates, as far as possible, existing rules and forms a code of interpretation, where applicable, of the requirements laid down by the International Maritime Organization, and constitutes a guide for future regulations which may be prepared and a statement of practice for offshore unit owners, constructors and appropriate organizations.
BS IEC 61892-7 is based on equipment and practices which are in current use, but it is not intended in any way to impede development of new or improved techniques.
The ultimate aim has been to produce a set of International Standards exclusively for the offshore petroleum industry.
This part of IEC 61892 contains provisions for hazardous areas classification and choice of electrical installation in hazardous areas in mobile and fixed offshore units, including pipeline, pumping or ‘pigging stations, compressor stations and exposed location single buoy moorings, used in the offshore petroleum industry for drilling, processing and for storage purposes.
It applies to all installations, whether permanent, temporary, transportable or hand-held, to a.c. installations up to and including 35 000 V and d.c. installations up to and including 750 V.(a.c. and d.c. voltages are nominal values).
BS IEC 61892-7 does not apply to electrical installations in rooms used for medical purposes, or in tankers.
