    26、al Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this e

    27、nd and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Com

    28、mittee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in a

    29、ccordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all

    30、 interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held re

    31、sponsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any diverg

    32、ence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC ma

    33、rks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual exper

    34、ts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Pu

    35、blication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Pu

    36、blication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61892-3 has been prepared by IEC technical committee 18: Electrical installations of ships and of mobile and fixed offshore units. This third edi

    37、tion cancels and replaces the second edition published in 2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Table 4 in the previous edition of IEC 61892-3 regarding type testing has been del

    38、eted. Information regarding environmental conditions, including requirements to vibration, is now given in Clause 4; b) for liquid immersed transformers requirement for overheating alarm and shut down has been added; BS IEC 61892-3:201261892-3 IEC:2012(E) 7 c) requirements for low voltage switchgear

    39、 and controlgear have been rewritten, based on IEC 61439-1 and IEC 61439-2. Only additional requirements to those given in IEC 61439 are given in the standard; d) requirements to low voltage circuit breakers, switches, contactors and fuses have been added; e) requirement for subdivision of high volt

    40、age switchboard has been added; f) requirements for luminaires have been deleted and replaced with reference to IEC 60598 series and IEC 60092-306; g) requirements for heating and cooking appliances have been deleted and replaced with reference to IEC 60335 series; h) requirement for portable equipm

    41、ent has been added. The text of this standard is based on the following documents: FDIS Report on voting 18/1241/FDIS 18/1256/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in a

    42、ccordance with the ISO/IEC Directives, Part 2. A list of all the parts of the IEC 61892 series, under the general title Mobile and fixed offshore units Electrical installations, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged unt

    43、il the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later

    44、 date. BS IEC 61892-3:2012 8 61892-3 IEC:2012(E) INTRODUCTION IEC 61892 forms a series of International Standards intended to enable safety in the design, selection, installation, maintenance and use of electrical equipment for the generation, storage, distribution and utilisation of electrical ener

    45、gy for all purposes in offshore units which are being used for the purpose of exploration or exploitation 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 of

    46、 the International Maritime Organisation (IMO), a guide for future regulations which may be prepared and a statement of practice for offshore unit owners, constructors and appropriate organisations. This standard is based on equipment and practices which are in current use but it is not intended in

    47、any way to impede the development of new or improved techniques. The ultimate aim has been to produce a set of International standards exclusively for the offshore petroleum industry. BS IEC 61892-3:201261892-3 IEC:2012(E) 9 MOBILE AND FIXED OFFSHORE UNITS ELECTRICAL INSTALLATIONS Part 3: Equipment

    48、1 Scope This part of IEC 61892 contains provisions for electrical equipment 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 stor

    49、age purposes. This standard applies to equipment in 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 1 500 V (a.c. and d.c. voltages are nominal values). This standard sets requirements for equipment, which are additional to the requirements given in the product standard for the relevant equipment. This standard does not apply to the electrical install
