21、WORD 1) The International Electrotechnical 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 ele
22、ctrical and electronic fields. To this end 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 te
23、chnical committees; any IEC National Committee 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 Org
24、anization for Standardization (ISO) in accordance 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 technic
25、al committee has representation from all 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 Publica
26、tions is accurate, IEC cannot be held responsible 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 nation
27、al and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be
28、in conformity with an IEC Publication. 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 experts and members of its technical committees and IEC National Committee
29、s 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 Publication or any other IEC Publications. 8) Attention is drawn to the
30、 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 Publication may be the subject of patent rights. IEC shall not be held
31、responsible for identifying any or all such patent rights. International Standard IEC 60364-5-56 has been prepared by IEC technical committee 64: Electrical installations and protection against electric shock. This second edition of IEC 60364-5-56 comes about as a result of changes to Clause 556, Sa
32、fety services, of IEC 60364-5-55 (2001), as modified by its amendment 1 (2001).1This new part replaces Clause 556 of IEC 60364-5-55:2001. Clause 556 is to be withdrawn at the time of publication of this new Part 56. The main changes with regard to the previous edition are listed below: 1) Many more
33、definitions are included, e.g. response time, central power supply system, low power supply system, preferential circuit and escape route. _ 1The first edition of IEC 60364-5-56, which was published in 1980, together with its amendment (1998), was withdrawn when its contents were incorporated into t
34、he first edition of IEC 60364-5-55. 4 60364-5-56 IEC:2009 2) Automatic supplies are now classified according to the maximum changeover times, for example a supply classified as short break means an automatic supply is available within 0,5 s. 3) Safety sources that can operate in parallel are specifi
35、cally recognized in 560.6.9. 4) Requirements are now given for batteries used for safety sources for central and low power supply sources. 5) Drawings are now required, such as a single-line diagram, drawings showing the location of equipment and a list of equipment permanently connected to the safe
36、ty power supply. 6) Operating instructions are now required. 7) Detailed requirements are now given for emergency escape lighting applications, direct current circuits and fire protection applications. 8) Additional requirements for initial verification and periodic inspection and testing are now in
37、cluded in the standard. 9) Two annexes are now included (Annex A and Annex B) giving guidance for emergency lighting and guidance for fire protection equipment, respectively. The text of this standard is based on the following documents: FDIS Report on voting64/1677/FDIS 64/1686/RVD Full information
38、 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 accordance with the ISO/IEC Directives, Part 2. The readers attention is drawn to the fact that Annex C lists all of the “in-some-country” clauses
39、on differing practices of a less permanent nature relating to the subject of this standard. A list of all parts in the IEC 60364 series, under the general title Low-voltage electrical installations, can be found on the IEC website. The committee has decided that the contents of this publication will
40、 remain unchanged until the maintenance result date indicated on the IEC website 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. 60364-5-56 IEC:2009 5 LOW-VOLTAGE E
