18、CHNICAL COMMISSION _ AUTOMATIC ELECTRICAL CONTROLS FOR HOUSEHOLD AND SIMILAR USE Part 2-19: Particular requirements for electrically operated oil valves, including mechanical requirements FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization

19、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 end and in addition to other activities, IEC publishes International

20、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 Committee interested in the subject dealt with may participate in this

21、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 accordance with conditions determined by agreement between the two o

22、rganizations. 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 interested IEC National Committees. 3) IEC Publications have the f

23、orm 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 responsible for the way in which they are used or for any misinterpre

24、tation 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 divergence between any IEC Publication and the corresponding national or

25、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. 6) All users should ensure that they have the latest edition of this

26、 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 damage or other damage of any nature whatsoever, whether direct or indi

27、rect, 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 publication. Use of the referenced publications is indispensable for th

28、e 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 all such patent rights. International Standard IEC 60730-2-19 has been p

29、repared by IEC technical committee 72: Automatic controls for household use. This consolidated version of IEC 60730-2-19 consists of the first edition (1997) documents 72/350/FDIS/ and 72/373/RVD, its amendment 1 (2000) documents 72/467/FDIS and 72/491/RVD and its amendment 2 (2007) documents 72/745

30、/FDIS and 72/750/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 base publication has been modified by amendments 1 and 2. SANS 60730-2-

31、19:2008This standard may only be used and printed by approved subscription and freemailing clients of the SABS. 4 60730-2-19 IEC:1997+A1:2000 +A2:2007 This Part 2-19 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) a

32、nd its amendment 1 (2003). Consideration may be given to future editions of, or amendments to IEC 60730-1. This part 2 supplements or modifies the corresponding clauses in IEC 60730-1, so as to convert that publication into the IEC standard: Particular requirements for electrically operated oil valv

33、es, including mechanical requirements. This publication has been drafted in accordance with the ISO/IEC Directives, Part 3. Where this part 2 states “addition“, “modification“ or “replacement“, the relevant requirement, test specification or explanatory matter in part 1 should be adapted accordingly

34、. 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 practical experience in various parts of the world and to re

35、cognize the variation in national electrical systems and wiring rules. The “in some countries” notes regarding differing national practice are contained in the following subclauses: Table 7.2, requirement 120 Table 7.2, note 102 11.103 11.105.1 11.105.2 11.113 18.102 27.2.101.1 H.26.10 In this publi

36、cation: 1) The following print types are used: requirements proper: in roman type; test specifications: in italic type; explanatory matter: in smaller roman type. 2) Subclauses, notes or items which are additional to those in part 1 are numbered starting from 101. The committee has decided that the

37、contents of the base publication and its amendments 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

38、 edition, or amended.

39、rated oil valves, including mechanical requirements 1 Scope and normative references This clause of part 1 is not applicable. Replacement: 1.1 This part 2 of IEC 60730 applies to electrically operated oil valves for use in, on or in association with equipment for household and similar use that use e

40、lectricity, in combination with fuel in the liquid state such as distillates, residual fuels, etc. This part 2 also applies to electrically operated oil 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 op

41、erating values, operating times, and operating sequences where such are associated with equipment safety, and to the testing of electrically operated oil valves used in, or in association with, household or similar equipment, but also extended to industrial purposes where no dedicated product standa

42、rd 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 does not apply to electrically oper

43、ated oil valves designed exclusively for industrial applications. Electrically operated oil 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 with

44、in 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 an electrically operated oil valve

45、 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 oil valves. Requirements for manual switches not forming

46、part of an electrically operated oil valve are contained in IEC 61058-1. This part 2 does not apply to electrically operated oil valves of nominal connection size above DN 150. Hereinafter, the term “valve“ is used to denote an electrically operated oil valve (including prime mover and valve body).
