FOREWORD


This amendment has been prepared by committee 61: Safety of household and similar

electrical appliances.


The text of this amendment is based on the following documents:


FDIS Report on voting

61/4444/FDIS 61/4497/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 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• withdrawn,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.

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.

22 Construction
22.105 Replace the existing text by the following:
UV appliances that are inclined at an angle of more than 35° to the vertical shall be
constructed so that the emission of ultraviolet radiation is automatically stopped if the timer
fails.
Compliance is checked by the following tests.
The appliance is supplied at rated voltage and operated under normal operation. A fault in
the timer is simulated. The emission of ultraviolet radiation shall cease before the exposure
time has exceeded 110 % of the set value.
If compliance relies on the operation of an electronic circuit, the appliance is further tested
as follows.
The appliance is supplied at rated voltage and operated under normal operation. A fault in
the timer is simulated. The fault conditions in a) to g) of 19.11.2 are applied one at a time to
the electronic circuit. The emission of ultraviolet radiation shall cease before the exposure
time has exceeded 110 % of the set value and the appliance shall not be capable of further
use without repair.
If the electronic circuit is programmable, the software shall contain measures to control the
fault/error conditions specified in Table R.1 and is evaluated in accordance with
the relevant requirements of Annex R.

If compliance relies on the operation of an electronic circuit, the appliance is further tested
as follows.

---------------------- Page: 6 ----------------------
60335-2-27 Amend. 1 © IEC:2012 – 5 –


The appliance is supplied at rated voltage and the filter is removed. The fault conditions in a)

to g) of 19.11.2 are then applied one at a time to the electronic circuit. The appliance shall

comply with 32.101.


If the electronic circuit is programmable, the software shall contain measures to control the

fault/error conditions specified in Table R.1 and is evaluated in accordance with the relevant

requirements of Annex R.

Appliances that the user may lock from the inside shall include provision to gain access from

outside of the appliance when the appliance is locked.
Replace the first paragraph of the test specification by the following:
Compliance is checked by inspection and by the following test.
Add the following new subclauses:
22.114 Appliances for commercial use only that completely surround a person and that can
be locked from the inside shall include provision for the operator to gain access to the
appliance from the outside.

22.115 Glass parts of broken high-pressure metal halide lamps shall not be ejected from the
appliance or contact a user or cause a fire hazard if they contact non-metallic parts of the
appliance.
Compliance is checked by inspection and, if necessary, by the following test.
Non-metallic material that may be contacted by parts of broken high-pressure metal halide
lamps shall comply with IEC 60695-2-11 without ignition at a test severity of 750 °C. The
glow-wire test need not be carried out on parts that have a glow-wire ignition temperature
according to IEC 60695-2-13 of at least 775 °C.

Renumber the existing second Note 4 as Note 6 and existing Note 5 as Note 7.
Replace the fifth and sixth paragraphs of the test specification by the following:
Appliances suitable for household use shall have a total effective irradiance not exceeding
2
, for wavelengths up to 320 nm;
– 0,15 W/m
2
– 0,15 W/m , for wavelengths between 320 nm and 400 nm,
weighted according to the erythema action spectrum of Figure 103.
