24、 IEC 2014 3 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ HOUSEHOLD ELECTRIC HEATING PADS METHODS FOR MEASURING PERFORMANCE FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National
25、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 Standards, Technical Specifications, Technical Reports, Publicly A
26、vailable 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 preparatory work. International, governmental and non- governmenta
27、l 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 organizations. 2) The formal decisions or agreements of IEC on tech
28、nical 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 form of recommendations for international use and are accepted by I
29、EC 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 misinterpretation by any end user. 4) In order to promote international unifo
30、rmity, 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 regional publication shall be clearly indicated in the latter. 5)
31、IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensur
32、e 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 damage or other damage of an
33、y 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 publication. Use of the refe
34、renced 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 all such patent rights. Inter
35、national standard IEC 61255 has been prepared by sub-committee 59C: Heating appliances, of IEC technical committee 59: Performance of household electrical appliances. This second edition cancels and replaces the first edition published in 1994. This edition constitutes a technical revision. This edi
36、tion includes the following significant technical changes with respect to the previous edition: a) extended classification; b) extended list of measurements; c) temperature measurement means changed to thermocouples. 4 IEC 61255:2014 IEC 2014 The text of this standard is based on the following docum
37、ents: FDIS Report on voting 59C/182/FDIS 59C/183/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 publication has been drafted in accordance with the ISO/IEC Directives, Part 2. In this standard, the followin
38、g print types are used: test specifications: in italic type notes: in small roman type other text: in roman type terms defined in Clause 3: in bold type. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under
39、 “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. IEC 61255:2014 IEC 2014 5 HOUSEHOLD ELECTRIC HEATING PADS METHODS FOR MEASURING PERFORMANCE 1 Scope This International St
40、andard applies to electric heating pads for household use. This International Standard defines the main performance characteristics of electric heating pads and specifies methods for measuring these characteristics, for the information of users. This International Standard does not specify values fo
41、r performance characteristics. NOTE This International Standard does not deal with safety requirements that are covered by IEC 60335-2-17. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For d
42、ated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

43、rdness (indentation technique) 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 heating pad appliance comprising a flexible part having a heated area not exceeding 0,3 m 2on each face and which is intended to heat part of the human body Note 1
44、 to entry: If the pad is constructed in a cylindrical or similar form, the limit for heated area is 0,6 m 2 . 3.2 flexible part all layers of material forming the permanent enclosure of the appliance together with the heating element, thermostats and all other current-carrying parts contained within
45、 it Note 1 to entry: The flexible part may be inside a detachable cover. 3.3 heated area area of the flexible part enclosed within the outer perimeter of the heating element or electro-conductive textile Note 1 to entry: The heated area includes a margin outside the perimeter that has a width equal
46、to 0,5 times the average distance between adjacent runs of the heating element. Note 2 to entry: The heated area includes the return length of the heating element if the average distance between this part and the adjacent heating element does not exceed the average distance between adjacent runs of
47、the heating element. 6 IEC 61255:2014 IEC 2014 Note 3 to entry: If the heating pad has two separate heated areas, the surface between the two areas is considered to be part of the heated areas, if at any place the distance between the two heating elements does not exceed 1,5 times the average distan
