EN 60335-2-17:2013 includes the following significant technical changes with respect to EN 60335-2-17:2002: The definition of PTC heating element has been deleted and the de

16、finition in Part 1 now applies. A definition of a heating element with PTC characteristics has been introduced instead (3.117). This has resulted in editorial changes to 5.7, 5.8.2, 7.1, 10.101, 11.2, 21.105, 21.111.1 and 21.112. The allowance for class I appliances has been deleted and requirements

17、 for appliances incorporating a functional earth have been incorporated (6.1, 7.1, 22.115). The working voltage of parts of class III construction is limited to 24 V (22.26). Some notes have been deleted or converted to normative text (3.107, 3.111, 3.113, 5.2, 5.3, 5.8.2, 11.8, 11.101, 11.102, 15.1

Modification of the marking requirements (7.1, 7.14, 7.15). M

19、odification of the instructions (7.12). Clarification of the heat stroke test (11.101). The figure numbers have been updated to take into account deletion of Figure 103 in EN 60335-2-17:2002. This part 2 is to be used in conjunction with EN 60335-1:2012. NOTE 1 When “Part 1” is mentioned in this sta

20、ndard, it refers to EN 60335-1. This part 2 supplements or modifies the corresponding clauses in EN 60335-1, so as to convert that publication into the European Standard: Safety requirements for blankets, pads, clothing and similar flexible heating appliances. When a particular subclause of Part 1 i

21、s 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 in Part 1 is to be adapted accordingly. NOTE 2 The following numbering system is used: subclauses, tables and figures that are numb

22、ered starting from 101 are additional to those in Part 1; BS EN 60335-2-17:2013- 3 - EN 60335-2-17:2013 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 lettered AA, BB, etc.

23、 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.

40、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 account the m

41、anufacturers 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 that ther

42、e 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 applied to ea

43、ch 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 committees res

44、ponsible 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 a

45、nd generic standards covering the same subject. NOTE 2 Horizontal and generic standards covering a hazard are not applicable, since they have been taken into consideration when developing the general and particular requirements for the IEC 60335 series of standards. For example, in the case of tempe

46、rature requirements for surfaces on many appliances, generic standards, such as ISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or part 2 standards. An appliance that complies with the text of this standard will not necessarily be considered to comply with the safety principle

47、s of the standard if, when examined and tested, it is found to have other features that impair the level of safety covered by these requirements. An appliance employing materials or having forms of construction differing from those detailed in the requirements of this standard may be examined and te

48、sted according to the intent of the requirements and, if found to be substantially equivalent, may be considered to comply with the standard.

49、 and similar flexible heating appliances 1 Scope This clause of Part 1 is replaced by the following. This International Standard deals with the safety of electric blankets, pads, clothing and other flexible appliances that heat the bed or human body, for household and similar purposes, their rated voltage being not more than 250 V. This standard also applies to control units supplied with the appliance. Appliances not intended for normal household
