14 Transient overvoltages
Replace the second paragraph of the test specification by the following:
The impulse test voltage has a no-load waveshape corresponding to the 1,2/50 µs standard
impulse specified in IEC 61180-1. It is supplied from a generator having a conventional
impedance not exceeding 42 Ω. The impulse test voltage is applied three times for each
polarity with intervals of at least 1 s.
Delete Note 3.
16 Leakage current and electric strength
16.3 Replace the first paragraph of the test specification by the following:
Immediately after the test of 16.2, the insulation is subjected to a voltage having a frequency
of 50 Hz or 60 Hz for 1 min in accordance with IEC 61180-1. The values of the test voltage for
different types of insulation are given in Table 7.
Replace Note 2 by the following:
NOTE 2 The characteristics of the high-voltage source used for the test are described in Table 5.
Delete the penultimate paragraph of the test specification.
19 Abnormal operation
19.1 Add the following new paragraph after the third paragraph of the test specification:
Appliances incorporating contactors or relays are subjected to the test of 19.14.
Add the following new subclause:
19.7 In the second paragraph, replace “IEC 60252” by “IEC 60252-1”.
19.11 Replace the second and third paragraphs by the following:
Appliances incorporating an electronic circuit are subjected to the tests of 19.11.3 and
19.11.4.

Add the following as a new second paragraph:
Appliances incorporating an electronic circuit that relies upon a programmable component to
function correctly are subjected to the test of 19.11.4.8, unless restarting at any point in the
operating cycle after interruption of operation due to a supply voltage dip will not result in a
hazard. The test is carried out after removal of all batteries and other components intended to
maintain the programmable component supply voltage during mains supply voltage dips,
interruptions and variations.
In the existing third paragraph, replace “switch” by “device” in two places.
In the sixth paragraph replace “all three” by “both” and delete the last dashed item.
19.11.2 In the first paragraph of the test specification, add the following after Note 2:
g) failure of an electronic power switching device in a partial turn-on mode with loss of
gate (base) control. During this test, winding temperatures shall not exceed the values
given in 19.7.
NOTE 3 This mode may be simulated by disconnecting the electronic power switching device gate (base)
terminal and connecting an external adjustable power supply between the gate (base) terminal and the source
(emitter) terminal of the electronic power switching device. The power supply is then varied so as to achieve a
current that will not damage the electronic power switching device but give the most onerous conditions of test.
NOTE 4 Examples of electronic power switching devices are field effect transistors (FET’s and MOSFET’s) and
bipolar transistors (including IGBT’s).
19.11.4 In the first paragraph, replace “switch” by “device” in three places.
In the last paragraph, replace "arresters" by "protective devices“.
19.11.4.6 Replace the text by the following:
The appliance is subjected to the Class 3 voltage dips and interruptions in accordance with
IEC 61000-4-11. The values specified in Table 1 and Table 2 of IEC 61000-4-11 are applied
at zero crossing of the supply voltage.
Add the following new subclause:
19.11.4.8 The appliance is supplied at rated voltage and operated under normal operation.
After approximately 60 s, the power supply voltage is reduced to a level such that the
appliance ceases to respond to user inputs or parts controlled by the programmable
component cease to operate, whichever occurs first. This value of supply voltage is recorded.
The appliance is supplied at rated voltage and operated under normal operation. The
voltage is then reduced to a value of approximately 10 % less than the recorded voltage. It is
held at this value for approximately 60 s and then increased to rated voltage. The rate of
decrease and increase of the power supply voltage is to be approximately 10 V/s.
The appliance shall continue to either operate normally from the same point in its operating
cycle at which the voltage decrease occurred or a manual operation shall be required to
restart it.
19.13 Replace the second paragraph by the following:
After the tests, and when the appliance has cooled to approximately room temperature,
compliance with Clause 8 shall not be impaired and the appliance shall comply with 20.2 if it
can still be operated.
