batteries not charged inside the appliance" (see 5.17, Annex S of this Edition);
--- Add the test conditions for components or parts of appliances with both self-resetting and
non-self-resetting characteristics (see 5.19 of this Edition);
--- Add the method for determining the appliance category for "appliances consisting of
Class-III structural components and detachable power supply components" (see 6.1 of
this Edition);
--- Add the symbol requirements for "Class-II appliances with functional grounding",
"Class-III appliances", and "functional grounding terminal", etc. (see 7.1, 7.6, 7.8 of this
Edition);
--- Change the symbol corresponding to "Read the operating manual" (see 7.6 of this Edition;
7.6 of the 2005 Edition);
--- Add requirements for special populations, Class-III structures and Class-III appliances
in the instructions for use (see 7.12 of this Edition);
--- Add requirements for different languages and alternative formats of instructions for use
(see 7.12.9 of this Edition);
--- Add requirements for font height of warning words and requirements for molded,
engraved or stamped signs (see 7.14 of this Edition);
--- Add requirements for the marking position of symbol 5018 specified in IEC 60417 (see
7.15 of this Edition);
--- Add requirements and test methods for providing complete disconnection after the switch
device realizes a switching action (see 8.1.3 of this Edition);
--- Add the requirements of "For peak voltage greater than 15kV, the discharge energy shall
not exceed 350mJ" (see 8.1.4 of this Edition);
--- Change the input power measurement method of "appliances whose input power varies
throughout the working cycle" (see 10.1 of this Edition; 10.1 of the 2005 Edition);
--- Change the current measurement method of "appliances whose current varies throughout
the working cycle" (see 10.2 of this Edition; 10.2 of the 2005 Edition);
--- Change the maximum normal temperature rise requirements for the pins of the appliance
plugged into the fixed socket, the housing of the electric appliance, the handles, knobs,
grips and similar parts held in normal use (see Table 3 of this Edition; Table 3 of the 2005
Edition);
--- Change the leakage current test method and limit value of some types of appliances and
structures (see 13.2 of this Edition; 13.2 of the 2005 Edition);
--- Change the pulse test voltage values corresponding to some rated pulse voltages (see
Table 6 of this Edition; Table 6 of the 2005 Edition);
Safety of Household and Similar
Electrical Appliances – Part 1.General Requirements
1 Scope
This Document specifies the safety requirements for household and similar electrical appliances.
This Document applies to household and similar electrical appliances with a rated voltage not
exceeding 250V for single-phase appliances and a rated voltage not exceeding 480V for other
appliances.
NOTE 1.Battery-operated appliances and other d.c. supplied appliances are within the scope of this
Standard. Dual supply appliances, either mains-supplied or battery-operated, are regarded as battery-
operated appliances when operated in the battery mode.
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 by laymen in shops, in light industry
and on farms, are within the scope of this Standard.
NOTE 2.Examples of such appliances are catering equipment, cleaning appliances for commercial use,
and appliances for hairdressers.
This Standard deals with the reasonably foreseeable hazards presented by appliances that are
encountered by all persons. However, in general, it does not take into account.
– persons (including children) whose
• physical, sensory or mental capability imperfections; or
• lack of experience and knowledge
prevents them from using the appliance safely without supervision or instruction;
– children playing with the appliance.
NOTE 3.Attention is drawn to the fact that.
– for appliances intended to be used in vehicles or on-board ships or aircraft, additional requirements
may be necessary;
– in many countries, additional requirements are specified by the national health authorities, the
4 General Requirement
Appliances shall be constructed so that in normal use, they function safely so as to cause no
danger to persons or surroundings, even in the event of carelessness that may occur in normal
use.
In general, this principle is achieved by fulfilling the relevant requirements specified in this
standard and compliance is checked by carrying out all the relevant tests.
5 General Conditions for the Tests
Unless otherwise specified, the tests are carried out in accordance with this clause.
5.1 Tests according to this standard are type tests.
NOTE. Routine tests are described in Annex A.
5.2 The tests are carried out on a single appliance that shall withstand all the relevant tests.
However, the tests of Clauses 20, 22 (except 22.10, 22.11 and 22.18) to 26, 28, 30 and 31 may
be carried out on separate appliances. The test of 22.3 is carried out on a new appliance.
NOTE 1.Additional samples may be required if the appliance has to be tested under different conditions,
for example if it can be supplied with different voltages.
If an intentionally weak part becomes open circuit during the tests of Clause 19, an additional appliance
may be needed.
The testing of components may require the submission of additional samples of these components.
If the test of Annex C has to be carried out, six samples of the motor are needed.
If the test of Annex D has to be carried out, an additional appliance may be used.
If the tests of Annex G are carried out, four additional transformers are needed.
If the tests of Annex H are carried out, three switches or three additional appliances are needed.
NOTE 2.The cumulative stress resulting from successive tests on electronic circuits is to be avoided. It
may be necessary to replace components or to use additional samples. The number of additional samples
should be kept to a minimum by an evaluation of the relevant electronic circuits.
NOTE 3.If an appliance has to be dismantled in order to carry out a test, care is to be taken to ensure
that it is reassembled as originally supplied. In case of doubt, subsequent tests may be carried out on a
separate sample.
