20、lar requirements for flexible sheet heating elements for room heating 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 interna
21、tional 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 Available Specifications (PAS) and Guides (hereafter
22、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-governmental organizations liaising with the IEC also participat
23、e 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 technical matters express, as nearly as possible, an inte
24、rnational 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 IEC National Committees in that sense. While all reaso
25、nable 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 uniformity, IEC National Committees undertake to apply IEC
26、 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) IEC provides no marking procedure to indicate its app
27、roval 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 publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual
28、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 indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this I
29、EC 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 the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this I
30、EC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. This part of International Standard IEC 60335 has been prepared by IEC technical committee 61: Safety of household and similar electrical appliances. This consolidated
31、 version of IEC 60335-2-96 consists of the first edition (2002) documents 61/2088/FDIS and 61/2105/RVD, its amendment 1 (2003) documents 61/2429/FDIS and 61/2464/RVD, its amendment 2 (2008) documents 61/3693/FDIS and 61/3747/RVD and its corrigendum of May 2003. The technical content is therefore ide
32、ntical 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. The French version of amendment 1 has not been voted upon. SANS 60335-2-9
33、6:2009This s tandard may only be used and printed by approved subscription and freemailing clients of the SABS .60335-2-96 IEC:2002+A1:2003 5 +A2:2008 This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its amendments. It was established on the basis of the fourth edi
34、tion (2001) of that standard. NOTE 1 When “Part 1” is mentioned in this standard, it refers to IEC 60335-1. This part 2 supplements or modifies the corresponding clauses in IEC 60335-1, so as to convert that publication into the IEC standard: Safety requirements for electrical flexible sheet heating
35、 elements for room heating. When a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies as far as is reasonable. When this standard states “addition“, “modification“ or “replacement“, the relevant text of Part 1 is to be adapted accordingly. NOTE 2 The following num
36、bering system is used: subclauses, tables and figures that are numbered starting from 101 are additional to those in Part 1; unless notes are in a new subclause or involve notes in Part 1, they are numbered starting from 101, including those in a replaced clause or subclause; additional annexes are
37、lettered AA, BB, etc. NOTE 3 The following print types are used: requirements: in roman type; test specifications: in italic type; notes: in small roman type. Words in bold in the text are defined in Clause 3. When a definition concerns an adjective, the adjective and the associated noun are also in
38、 bold. The following additional differences exist in the countries indicated below. Clause 1: Flexible sheet heating elements that are cut on site are not allowed (France, Germany and Israel). 6.1: The installation is to be of class II construction (Germany). 6.1: Heating units are to be class II (I
39、srael). 7.1: The intended installation is not to include walls (Canada and USA). 7.12.1 c): The instructions in timber floors shall state that the heating unit is to be covered with additional insulation, be supplied through an isolating transformer, or be class II (Sweden). 7.12.1 c): The instructi
40、ons need not refer to residual current devices (USA). 7.12.101 a): The size of the terminals fitted to the grid may be smaller (Canada). Clause 18: The tests are different (USA). 22.102: The test is different (USA). 22.103: The test is different (USA). 25.3: Heating units are not allowed to incorpor
41、ate supply cords (Canada and USA). 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 related to the specific publication. At this date,
42、 the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. NOTE 4 The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC pu
43、blication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the recommendation of the committee that the content of the amendment 2 be adopted for implementation nationally not earlier than 12 months or later than 36
44、months from the date of publication. 2 SANS 60335-2-96:2009This s tandard may only be used and printed by approved subscription and freemailing clients of the SABS . 6 60335-2-96 IEC:2002+A1:2003 +A2:2008 INTRODUCTION It has been assumed in the drafting of this International Standard that the execut
45、ion of its provisions is entrusted to appropriately qualified and experienced persons. This standard recognizes the internationally accepted level of protection against hazards such as electrical, mechanical, thermal, fire and radiation of appliances when operated as in normal use taking into accoun
46、t the manufacturers instructions. It also covers abnormal situations that can be expected in practice and takes into account the way in which electromagnetic phenomena can affect the safe operation of appliances. This standard takes into account the requirements of IEC 60364 as far as possible so th
47、at there is compatibility with the wiring rules when the appliance is connected to the supply mains. However, national wiring rules may differ. If an appliance within the scope of this standard also incorporates functions that are covered by another part 2 of IEC 60335, the relevant part 2 is applie
48、d to each function separately, as far as is reasonable. If applicable, the influence of one function on the other is taken into account. When a part 2 standard does not include additional requirements to cover hazards dealt with in Part 1, Part 1 applies. NOTE 1 This means that the technical committ
49、ees responsible for the part 2 standards have determined that it is not necessary to specify particular requirements for the appliance in question over and above the general requirements. This standard is a product family standard dealing with the safety of appliances and takes precedence over horizontal and generic standards covering the same subject. NOTE 2 Horizontal and generic standards covering a hazard are not applicable since they have been taken into
