FOREWORD
This amendment has been prepared by IEC technical committee 61: Safety of household and
similar electrical appliances.
The text of this amendment is based on the following documents:
FDIS Report on voting
61/3562/FDIS 61/3638/RVD
Full information on the voting for the approval of this amendment can be found in the report
on voting indicated in the above table.
The committee has decided that the contents of this amendment and the base publication 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, the
publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
NOTE 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 publication 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 this publication be adopted for implementation
nationally not earlier than 12 months or later than 36 months from the date of publication.

Title
Replace the title by the following:
Household and similar electrical appliances – Safety – Part 2-17: Particular
requirements for blankets, pads, clothing and similar flexible heating appliances
CONTENTS
Add the following:
Annex CC (normative) Clothing
INTRODUCTION
Replace the fifth paragraph by the following:
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 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.
60335-2-17 Amend. 2 © IEC:2008 – 3 –
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
consideration when developing the general and particular requirements for the IEC 60335 series of standards. For
example, in the case of temperature 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.
1 Scope
In the second paragraph, replace “pads” by “pads, clothing”.
Add the following after the third paragraph:
Appliances not intended for normal household use but which nevertheless may be a source of
danger to the public, such as appliances intended to be used in beauty parlours or by persons
in cold ambient temperatures, are within the scope of this standard.
Requirements and tests for clothing are given in Annex CC.
Replace the two dashed items in the existing fourth paragraph by the following:
– persons (including children) whose
• physical, sensory or mental capabilities; or
• lack of experience and knowledge
prevents them from using the appliance safely without supervision or instruction;
– children playing with the appliance.
2 Normative references
Replace the reference to ISO 3758 by the following:
ISO 3758:2005, Textiles – Care labelling code using symbols
5 General conditions for the tests
Add the following subclause:
5.12 Modification:
In the note, replace “25 %” by “10 %”.
6 Classification
6.1 Replace the first sentence of the modification by the following:
Appliances shall be class I, class II or class III.
Add the following note:
NOTE 101 Class I appliances are only provided with an earth for functional purposes.
– 4 – 60335-2-17 Amend. 2 © IEC:2008
7 Marking and instructions
7.1 In the fifth paragraph of the addition, as modified by Amendment 1, make the following
changes:
a) in the first dashed item, replace “1641 of ISO 7000” by “ISO 7000-0790”;
b) add the following dashed item after the fourth dashed item:
– intended orientation of blankets and mattresses (this marking is not required if the
appliance complies with 11.101, whichever way it is placed on the bed);
c) in the existing fifth dashed item, replace “for moisture-proof appliances” by “for
moisture-proof appliances or class III appliances”.
Add the following to the last paragraph of the addition:
Washable appliances fitted with a non-detachable flexible cord shall be marked with the
“hand wash” symbol specified in Table 1 of ISO 3758. Non-washable appliances shall be
marked with the “do not wash” symbol in Table 1 of ISO 3758.
Add the following subclause:
7.6 Addition:
[symbol IEC 60417-5017 (2006-08)] earth
[symbol from Table 1 of ISO 3758] hand wash
[symbol from Table 1 of ISO 3758] do not wash
7.12 Add the following:
The instructions for washable appliances fitted with a non-detachable cord shall state that
the switch or control unit must not be allowed to get wet during washing and that during drying
the cord must be positioned to ensure that water does not flow into the switch or control.
The instructions for non-washable appliances shall state how they can be cleaned, for
example with a damp sponge.
11 Heating
11.101 Replace the last paragraph of the test specification by the following:
The temperature shall not exceed 60 °C during the first hour of operation. It shall then not
exceed
– 45 °C, for one third of the length of the flexible part nearest the foot end of the bed;
– 37 °C, for the remainder of the flexible part.
15 Moisture resistance
15.101 In the penultimate paragraph, replace “clearances and creepage distances” by
“clearances or creepage distances”.
Add the following:
60335-2-17 Amend. 2 © IEC:2008 – 5 –
The flexible part of washable appliances fitted with a non-detachable flexible cord is
immersed again in the saline solution until it is saturated. It is then folded about its major axis
and placed over a line located 2 m above the floor. The cord is freely suspended, any excess
length being stretched out along the floor, and the flexible part allowed to drip-dry for 24 h.
The switch or control unit shall then withstand the electric strength test of 16.3 and
inspection shall show that there is no trace of water on insulation that could result in a
reduction of clearances or creepage distances below the values specified in Clause 29.
15.102 In the last paragraph, replace “clearances and creepage distances” by “clearances
or creepage distances”.
15.103 In the last paragraph, replace “clearances and creepage distances” by “clearances
or creepage distances”.

19.101 Replace “the flexible part is folded” by “the flexible part is uncovered and folded”.
19.102 Replace “the flexible part is folded” by “the flexible part is uncovered and folded”.
19.103 Replace “the flexible part is folded” by “the flexible part is uncovered and folded”.
19.105 Replace “the flexible part is folded” by “the flexible part is uncovered and folded”.
21 Mechanical strength
21.105 In the second paragraph, replace “thermal insulation 90 mm thick” by “thermal
insulation, as specified in Annex AA, having a thickness of 90 mm”.
21.111 Add the following:
The tests are also applied to a sheath that comprises basic insulation over earthed parts
when the sheath is integral with the heating element.
22 Construction
Add the following new subclauses:
22.115 The flexible part of class I appliances shall have at least double insulation or
reinforced insulation between live parts and earthed parts. There shall be at least basic
insulation between earthed parts and accessible parts.
– 6 – 60335-2-17 Amend. 2 © IEC:2008
Compliance is checked by inspection.
22.116 Wraps and pads intended to be used in close contact with the human body in order
to provide heat to create moisture for cosmetic purposes shall be moisture-proof appliances
or the flexible part shall be class III construction.
NOTE Lotions may be used to enhance the moist conditions.
Compliance is checked by inspection and test.
