17、 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 end and in addition to other activities, IEC publish

18、es 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 Committee interested in the subject dealt with may par

19、ticipate 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) in accordance with conditions determined by agreement

20、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 all interested IEC National Committees. 3) IEC Public

21、ations 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 responsible for the way in which they are used or fo

22、r 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 divergence between any IEC Publication and the correspon

23、ding 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. 6) All users should ensure that they have the lates

24、t 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 damage or other damage of any nature whatsoever, wheth

25、er 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 publication. Use of the referenced publications is ind

26、ispensable 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 all such patent rights. International Standard IEC 6073

27、0-2-14 has been prepared by IEC technical committee 72: Automatic controls for household use. This consolidated version of IEC 60730-2-14 consists of the first edition (1995) documents 72/307/FDIS and 72/339/RVD, its amendment 1 (2001) documents 72/480/FDIS and 72/502/RVD and its amendment 2 (2007)

28、documents 72/748/FDIS and 72/756/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

29、2. SANS 60730-2-14:2008This standard may only be used and printed by approved subscription and freemailing clients of the SABS. 4 60730-2-14 IEC:1995+A1:2001 +A2:2007 This Part 2-14 is intended to be used in conjunction with IEC 60730-1. It was established on the basis of the third edition of that s

30、tandard (1999) and its amendment 1 (2003). Consideration may be given to future editions of, or amendments to, IEC 60730-1. This part 2-14 supplements or modifies the corresponding clauses in IEC 60730-1, so as to convert that publication into the IEC standard: Particular requirements for electric a

31、ctuators. Where this part 2-14 states “addition“, “modification“ or “replacement“, the relevant require- ment, test specification or explanatory matter in part 1 should be adapted accordingly. Where no change is necessary part 2-14 indicates that the relevant clause or subclause applies. In the deve

32、lopment 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 recognize the variation in national electrical systems and wiring rules. The “in some countries“ notes regard

33、ing differing national practice are contained in the following subclauses: Table 7.2 14.4 27.2.1 Annex D 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, note

34、s or items 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 the IEC web site under “http:/webstore.iec.ch“ in the data re

35、lated to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended.

36、07 AUTOMATIC ELECTRICAL CONTROLS FOR HOUSEHOLD AND SIMILAR USE Part 2-14: Particular requirements for electric actuators 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 electric actuators for use in, on, or in

37、 association with equipment for household and similar use for heating, air-conditioning and ventilation. The equipment may use electricity, gas, oil, solid fuel, solar thermal energy, etc., or a combination thereof. This part 2 applies to electric actuators using NTC or PTC thermistors, additional r

38、equire- ments for which are contained in annex J. 1.1.1 This part 2 applies 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 electric actuators used in, on or in association with, equipment

39、for household and similar use for heating, air-conditioning and ventilation. Requirements for specific operating values, operating times and operating sequences may be given in the standards for appliances and equipment. Throughout this part 2 the word “equipment“ means “appliance and equipment“. El

40、ectric actuators 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 this part 2. This part 2 does not apply to electric actuators desi

41、gned exclusively for industrial applications. This part 2 does not apply to electric actuators which are mechanically integral with valves. See IEC 60730-2-8, Particular requirements for electrically operated valves, including mechanical requirements and IEC 60730-2-17, Particular requirements for e

42、lectrically operated gas valves. This part 2 does not apply to electric motors, requirements for which are contained in IEC 60034. 1.1.2 Requirements for manual switches not integral with an electric actuator are contained in IEC 61058-1. 1.2 Replacement This part 2 applies to electric actuators wit

43、h a rated voltage not exceeding 690 V and with a rated current not exceeding 63 A. 1.3 Replacement This part 2 does not take into account the response value of an automatic action of an electric actuator, if such a response value is dependent upon the method of mounting the electric actuator in the

44、equipment. Where a response value is of significant purpose for the protection of the user, or surroundings, the value defined in the appropriate household equipment or as determined by the manufacturer shall apply.
