19、ical 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

20、 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 technical committees; any IEC National C

21、ommittee 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) i

22、n 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 technical committee has representation from

23、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 Publications is accurate, IEC cannot be held

24、 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 national and regional publications. Any div

25、ergence 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 in conformity with an IEC Publication

26、. 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

27、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

28、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

29、l such patent rights. International Standard IEC 60730-2-17 has been prepared by IEC technical committee 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 7

30、2/466/FDIS and 72/490/RVD and its amendment 2 (2007) documents 72/744/FDIS and 72/749/RVD. The technical 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 ba

31、se publication has been modified by amendments 1 and 2. SANS 60730-2-17:2008This standard may only be used and printed by approved subscription and freemailing clients of the SABS. 4 60730-2-17 IEC:1997+A1:2000 +A2:2007 This Part 2-17 is intended to be used in conjunction with IEC 60730-1. It was es

32、tablished 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“, “modification“ or “replacement“, the relevant requirement, test specification or explan

33、atory 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 take into consideration the differing requirements resulting from practica

34、l 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 subclauses: 6.11.101 6.103 6.104 Table 7.2, requirements 117 and 118 Table 7.2

35、, 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: Requirements proper: in roman type; Test specifications: in italic type; Explanat

36、ory 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 amendments will remain unchanged until the maintenance result date indicated on

37、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.

39、 follows: Replacement: 1.1 This part 2 of IEC 60730 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 petrol

40、eum gas intended to be used for gas burning equipment. 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

41、 to the inherent safety, to the operating values, 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

42、 when no dedicated product standard exists, such 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 do

43、es not apply to electrically operated gas valves 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 ligh

44、t industry and on farms, are within the scope of 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 a

45、n electrically operated gas valve with this part 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

46、 for manual switches not forming part of an electrically operated gas valve are contained in IEC 61058-1. SANS 60730-2-17:2008This standard may only be used and printed by approved subscription and freemailing clients of the SABS. 6 60730-2-17 IEC:1997+A1:2000 +A2:2007 This part 2 does not apply to

47、electrically operated gas valves of nominal connection size above DN 150. This part 2 applies to electrically operated gas valves for maximum working pressures up to 400 kPa (4 bar). Hereinafter, the term “valve“ is used to denote an electrically operated gas valve (including prime mover and valve b

48、ody). 1.1.3 An electric actuator that is submitted to the testing laboratory in combination with a gas valve will be evaluated under this part 2. A separate electric actuator is evaluated under IEC 60730-2-14, which provides particular requirements for electric actuators. 1.1.4 This part 2 also appl

49、ies to valves utilized as part of a system, or valves mechanically integral with multifunctional controls. 1.1.5 This part 2 does not apply to valves energized by thermoelectric energy generated in a thermocouple or thermopile inserted in a gas flame. 1.3 Is not applicable. 1.5 Normative references This clause of part 1 is applicable except as follows: Addition: IEC 60730-2-14:2001, Automatic electrical controls for household and similar use Part 2: Particular r
