16、nd water level sensing controls FOREWORD 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 c

17、oncerning standardization in the electrical 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)”).

18、Their preparation is entrusted to technical 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 collaborat

19、es closely with the International Organization 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

20、 relevant subjects since each technical 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

21、 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 promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the ma

22、ximum extent possible in their national 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 responsi

23、ble 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 shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical

24、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 legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publi

25、cations. 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 publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

26、patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60730-2-15 has been prepared by IEC technical committee 72: Automatic controls for household use. This second edition cancels and replaces the first edition published in 1994 an

27、d its Amendment 1 (1997), the first edition of IEC 60730-2-16 published in 1995 and its Amendments 1 (1997) and 2 (2001) and the first edition of IEC 60730-2-18 published in 1997. This second edition constitutes a technical revision. This second edition is a consolidation of three standards IEC 6072

28、5-2-15, IEC 60730-2-16 and IEC 60730-2-18. The title and scope were revised to reflect the additional topics covered by the standard.

29、andard is based upon the following documents: FDIS Report on voting 72/757A/FDIS 72/761/RVD Full information on the voting for the approval of this part 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, Par

30、t 2. This Part 2-15 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 Amendments 1 (2003) and 2 (2007). Consideration may be given to future editions of, or amendments to, IEC 60730-1. This Part 2-15 supplemen

31、ts or modifies the corresponding clauses in IEC 60730-1 so as to convert that publication into the IEC standard: Particular requirements for automatic electrical air flow, water flow and water level sensing controls. Where this Part 2-15 states “addition“, “modification“ or “replacement“, the releva

32、nt requirement, test specification or explanatory matter in Part 1 should be adapted accordingly. Where no change is necessary, this Part 2-15 indicates that the relevant clause or subclause applies. In the development of a fully international standard, it has been necessary to take into considerati

33、on 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 subclauses: - 10.1.4 - 12

34、.1.1.101 In this publication: 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 or figures which are additional to those in Part 1 are numbered starting from 101. A list of all part

35、s of the IEC 60730 series, under the general title: Automatic electrical controls for household and similar use, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site unde
