21、mmission (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 end an
22、d 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 Committe
23、e 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) in accor
24、dance 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 all int
25、erested 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 respon
26、sible 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 divergence
27、 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks
28、of conformity. IEC is not responsible for any services carried out by independent certification bodies. 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 a
29、nd 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 legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Public
30、ation 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 publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Public
31、ation may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60730-2-9 has been prepared by technical committee TC 72: Automatic electrical controls. The text of this standard is based on the following document
32、s: FDIS Report on voting 72/990/FDIS 72/998/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This fourth edition cancels and replaces the third edition published in 2008, and its Amendment 1:2011. This edition con
33、stitutes a technical revision. This edition includes alignment with the text of 60730-1 fifth edition and the following significant technical changes with respect to the previous edition: IEC 60730-2-9:2015 IEC 2015 5 a) modification of heating-freezing tests in Clause 12; b) alignment of the EMC re
34、quirements in H.26 to those in other part 2 standards; c) addition of requirements in Clause H.27 to cover class B and C control functions of temperature sensing controls; This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. This Part 2-9 is intended to be used in con
35、junction with IEC 60730-1. It was established on the basis of the fifth edition (2013) of that publication. Consideration may be given to future editions of, or amendments to, IEC 60730-1. This Part 2-9 supplements or modifies the corresponding clauses in IEC 60730-1 so as to convert that publicatio
36、n into the IEC standard: Particular requirements for temperature sensing controls. Where this Part 2-9 states “addition“, “modification“, or “replacement“, the relevant requirement, test specification or explanatory matter in part 1 should be adapted accordingly. Where no change is necessary, this p
37、art 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 recognize the variation in nationa
38、l electrical systems and wiring rules. The “in some countries” notes regarding differing national practices are contained in the following subclauses: 4.1.101 17.8.4.101 Annex AA 7.2, Table 1 17.16.101 Clause CC.2 11.4.101 17.16.102 DD.9.2 11.101 17.16.105 EE.3.6 12.101.3 18.102.3 13.2 23.101 In thi
39、s publication: 1) The following print types are used: Requirements proper: in roman type; Test specifications: in italic type; Notes; in small roman type; Words defined in Clause 2: bold. 2) Subclauses, notes, tables and figures which are additional to those in part 1 are numbered starting from 101,
40、 additional annexes are lettered AA, BB, etc. A list of all parts of the IEC 60730 series, published under the title Automatic electrical controls can be found on the IEC website. 6 IEC 60730-2-9:2015 IEC 2015 The committee has decided that the contents of this publication will remain unchanged unti
41、l the stability 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. A bilingual version of this publication may be issued at a later

IEC 60730-2-9:2015 IEC 2015 7 AUTOMATIC ELECTRICAL CONTROLS Part 2-9: Particular requirements for temperature sensing controls 1 Scope and normative references This clause of Part 1 is applicable except as follows: 1.1 Scope Replacement: This part of IEC 60730 applies to automatic electrical t
43、emperature sensing controls for use in, on or in association with equipment, including electrical controls for heating, air-conditioning and similar applications. The equipment may use electricity, gas, oil, solid fuel, solar thermal energy, etc., or a combination thereof. NOTE Throughout this stand
44、ard, the word “equipment“ includes “appliance“ and “control system“. This standard is applicable to automatic electrical temperature sensing controls forming part of a building automation control system within the scope of ISO 16484. This standard also applies to automatic electrical temperature sen
45、sing controls for equipment that may be used by the public, such as equipment intended to be used in shops, offices, hospitals, farms and commercial and industrial applications. This standard does not apply to automatic electrical temperature sensing controls intended exclusively for industrial proc
46、ess applications, unless explicitly mentioned in the relevant equipment standard. 1.1.1 Replacement: This standard 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 automatic electr
47、ical temperature sensing control devices used in, or in association with, equipment. NOTE Examples of such controls include boiler thermostats, fan controls, temperature limiters and thermal cut-outs. This standard is also applicable to the functional safety of low complexity safety-related temperat
48、ure sensing controls and systems. 1.1.2 Addition: This standard also applies to the electrical safety of temperature sensing controls with non- electrical outputs such as refrigerant flow and gas controls. 8 IEC 60730-2-9:2015 IEC 2015 1.1.3 Not applicable. 1.1.4 Replacement: This standard applies t
49、o manual controls when such are electrically and/or mechanically integral with automatic temperature sensing controls. NOTE Requirements for manual switches not forming part of an automatic control are contained in IEC 61058-1. 1.1.5 Replacement: This standard applies to a.c. or d.c. powered temperature sensing controls with a rated voltage not exceeding 690 V a.c. or 600 V d.c. 1.1.6 Replacement: This standard does not take into account the response value of an automat
