26、ATIONAL ELECTROTECHNICAL COMMISSION _ AUTOMATIC ELECTRICAL CONTROLS Part 2-5: Particular requirements for automatic electrical burner control systems FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnic
27、al 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 end and in addition to other activities, IEC publishes International Standards, Technical Specifications, T
28、echnical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, gover
29、nmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions o
30、r 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 interested IEC National Committees. 3) IEC Publications have the form of recommendations for internationa
31、l 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 responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to
32、promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly i
33、ndicated 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 marks of conformity. IEC is not responsible for any services carried out by independent certification bodies
34、. 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 Committees for any personal injury, property d
35、amage 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 Normative references cited in this p
36、ublication. 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 responsible for identifying any or al
37、l such patent rights. International Standard IEC 60730-2-5 has been prepared by IEC technical committee 72: Automatic electrical controls. The text of this standard is based on the following documents: FDIS Report on voting 72/922/FDIS 72/929/RVD Full information on the voting for the approval of th
38、is 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. 60730-2-5 IEC:2013 5 This part 2-5 is intended to be used in conjunction with IEC 60730-1. It was established on the basis of the fourth
39、 edition (2010) of that publication. Consideration may be given to future editions of, or amendments to, IEC 60730-1. The title of IEC 60730-2-5 Ed. 4 has been updated to the title of IEC 60730-1 Ed. 5.0. However, IEC 60730-2-5 Ed. 4.0 has not been updated in accordance with the technical requiremen
40、ts in IEC 60730-1 Ed. 5.0. This part 2-5 supplements or modifies the corresponding clauses in IEC 60730-1 so as to convert that publication into the IEC standard: Safety requirements for automatic electrical burner control systems. Where this part 2-5 states “addition“, “modification“, or “replaceme
41、nt“, the relevant requirement, test specification or explanatory matter in Part 1 should be adapted accordingly. Where no change is necessary, this part 2-5 indicates that the relevant clause or subclause applies. In the development of a fully international standard, it has been necessary to take in
42、to consideration the differing requirements resulting from practical experience in various parts of the world and to recognize the variation in national electrical systems and wiring rules. The “in some countries” notes regarding differing national practices are contained in the following subclauses
43、: 2.3.127 6.11 15.7 17.16.102.1 H.26.11.103 Table H.21, Note 7 In this publication: 1) The following print types are used: Requirements proper: in roman type; Test specifications: in italic type; Explanatory matter; in small roman type; Words defined in Clause 2: bold. 2) Subclauses, notes, tables a
44、nd figures which are additional to those in Part 1 are numbered starting from 101, additional annexes are lettered AA, BB, etc. A list of all parts of the IEC 60730 series, under the general title Automatic electrical controls can be found on the IEC website. The committee has decided that the conte
45、nts of this publication will remain unchanged until 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. 6 60730-2-5 IEC
46、:2013 AUTOMATIC ELECTRICAL CONTROLS Part 2-5: Particular requirements for automatic electrical burner control systems 1 Scope and normative references This clause of Part 1 is applicable except as follows: 1.1 Replacement: This part of IEC 60730 applies to automatic electrical burner control systems
47、 for the automatic control of burners for oil, gas, coal or other combustibles for household and similar use including heating, air conditioning and similar use. This part 2-5 is applicable to a complete burner control system and to a separate programming unit. This part 2-5 is also applicable to a
48、separate electronic high-voltage ignition source and to a separate flame detector. NOTE Separate ignition devices (electrodes, pilot burners, etc.) are not covered by this part 2-5 unless they are submitted as part of a burner control system. Requirements for separate ignition transformers are conta
49、ined in IEC 60989. Throughout this part 2-5, where it can be used unambiguously, the word “system“ means “burner control system“ and “systems“ means “burner control systems“. Systems utilizing thermoelectric flame supervision are not covered by this part 2-5. 1.1.1 This part 2-5 applies to the inherent safety, to the manufacturers declared operating values, operating times and operating sequences where su
