23、C ELECTRICAL CONTROLS FOR HOUSEHOLD AND SIMILAR USE Part 2-17: Particular requirements for electrically operated gas valves, including mechanical requirements FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national elect

24、rotechnical 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 Specific

25、ations, 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 Committee interested in the subject dealt with may participate in this preparatory work. Internation

26、al, 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 accordance with conditions determined by agreement between the two organizations. 2) The formal de

27、cisions 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 interested IEC National Committees. 3) IEC Publications have the form of recommendations for int

28、ernational 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

29、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 divergence between any IEC Publication and the corresponding national or regional publication shall be

30、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 in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability

31、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 damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including

32、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 publication. Use of the referenced publications is indispensable for the correct application of this

33、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 all such patent rights. International Standard IEC 60730-2-17 has been prepared by IEC technical commi

34、ttee 72: Automatic controls for household use. This consolidated version of IEC 60730-2-17 consists of the first edition (1997) documents 72/348/FDIS and 72/371/RVD, its amendment 1 (2000) documents 72/466/FDIS and 72/490/RVD and its amendment 2 (2007) documents 72/744/FDIS and 72/749/RVD. The techn

35、ical content is therefore identical to the base edition and its amendments and has been prepared for user convenience. It bears the edition number 1.2. A vertical line in the margin shows where the base publication has been modified by amendments 1 and 2. 4 60730-2-17 IEC:1997+A1:2000 +A2:2007 This

36、Part 2-17 is intended to be used in conjunction with IEC 60730-1. It was established on the basis of the third edition of that standard (1999) and its amendment 1 (2003). Consideration may be given to future editions of, or amendments to IEC 60730-1. Where this part 2 states “addition“, “modificatio

37、n“ or “replacement“, the relevant requirement, test specification or explanatory matter in part 1 should be adapted accordingly. Where no change is necessary, part 2 indicates that the relevant clause or subclause applies. In the development of a fully international standard it has been necessary to

38、 take into 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 practice are contained in the following sub

39、clauses: 6.11.101 6.103 6.104 Table 7.2, requirements 117 and 118 Table 7.2, notes 103 and 104 11.102 11.103 11.104.3 11.104.5 11.104.11 11.104.14 11.105.1 11.105.2 11.105.3 11.105.6 11.106.1 11.115 17.16.101 18.102 18.103 27.2.101.1 In this publication: 1) The following print types are used: Requir

40、ements proper: in roman type; Test specifications: in italic type; Explanatory matter: in smaller roman type. 2) Subclauses, notes or requirements which are additional to those in part 1 are numbered starting from 101. The committee has decided that the contents of the base publication and its amend

41、ments will remain unchanged until the maintenance result 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. 60730-2-17 IEC:1997+A1:2

42、000 5 +A2:2007 AUTOMATIC ELECTRICAL CONTROLS FOR HOUSEHOLD AND SIMILAR USE Part 2-17: Particular requirements for electrically operated gas valves, including mechanical requirements 1 Scope and normative references This clause of part 1 is replaced as follows: Replacement: 1.1 This part 2 of IEC 607

43、30 applies to electrically operated gas valves for use in, on or in association with, equipment for household and similar use that use electricity, in combination with fuel in the gaseous state such as manufactured gas, natural gas or liquefied petroleum gas intended to be used for gas burning equip

44、ment. Additional considerations may be necessary for gas with corrosive properties. This part 2 also applies to electrically operated gas valves using NTC or PTC thermistors, requirements for which are contained in annex J. 1.1.1 This standard applies to the inherent safety, to the operating values,

45、 operating times, and operating sequences where such are associated with equipment safety, and to the testing of electrically operated gas valves used in, or in association with, household or similar equipment, but also extended to industrial purposes when no dedicated product standard exists, such

46、as that for central heating, air conditioning, process heating, etc. This part 2 is also applicable to controls for appliances within the scope of IEC 60335-1. Throughout this part 2 the word “equipment“ means “appliance and equipment“. This part 2 does not apply to electrically operated gas valves

47、designed exclusively for industrial applications. Electrically operated gas valves for equipment not intended for normal household use, but which nevertheless may be used by the public, such as equipment intended to be used by laymen in shops, in light industry and on farms, are within the scope of

48、this part 2. This part 2 identifies a number of mechanical features as “under consideration“. Until these mechanical requirements are incorporated in this part 2, each country using this part 2 will have to quantify these requirements. Compliance of an electrically operated gas valve with this part

49、2 does not imply that the valve is acceptable without further tests for these mechanical features. 1.1.2 This part 2 applies to manual controls when such are electrically and/or mechanically integral with electrically operated gas valves. Requirements for manual switches not forming part of an electrically operated gas valve are contained in IEC 61058-1. 6 60730-2-17 IEC
