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
61/5760/FDIS 61/5799/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 website 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• withdrawn,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.

_____________

Add the following new reference:
IEC 61558-2-4:2009, Safety of transformers, reactors, power supply units and similar products
for supply voltages up to 1 100 V – Part 2-4: Particular requirements and tests for isolating
transformers and power supply units incorporating isolating transformers
3 Terms and definitions
Replace the terms and definitions by the following:

© IEC 2019
3.1 Definitions relating to physical characteristics
3.1.1 Addition:
Note 1 to entry: The rated voltage is the rated input voltage.
3.1.6 Addition:
Note 2 to entry: The rated current is the rated input current.
3.1.9 Replacement:
normal operation
operation of the appliance under the following conditions:
Battery chargers for charging lead-acid batteries, and other battery chargers having a rated
DC output current not exceeding 20 A, are connected to the circuit of Figure 101. The
variable resistor is adjusted so that the current in the circuit is the rated DC output current
when the battery charger is supplied at rated voltage.
When the charging current is controlled by the state of charge of the battery, the variable
resistor and the capacitor are replaced by a discharged battery of the type and having the
largest capacity specified in the instructions.
Other battery chargers are connected to a discharged battery of the type and having the
largest capacity specified in the instructions.
3.1.101
rated DC output voltage
output voltage assigned to the battery charger by the manufacturer
3.1.102
rated DC output current
output current assigned to the battery charger by the manufacturer
3.2 Definitions relating to means of connection
3.2.2 Addition:
Output flexible cords are not considered to be interconnection cords.
3.4.3 Replacement:
safety isolating transformer
transformer, the input winding of which is electrically separated from the output winding by an
insulation at least equivalent to double insulation or reinforced insulation, that is intended
to supply a battery charging circuit having an output voltage not exceeding 120 V ripple-free
direct current
Note 1 to entry: Ripple-free means an r.m.s. ripple voltage not exceeding 10 % of the DC component.
3.5 Definitions relating to types of appliances
3.5.101
DC distribution board
panel having circuits for distributing DC power to socket-outlets or terminals

isolating transformer
transformer, the input winding of which is electrically separated from the output winding by an
insulation at least equivalent to double insulation or reinforced insulation, that is intended
to supply a battery charging circuit having an output voltage not exceeding 250 V
ripple-free DC
Note 1 to entry: Ripple-free means an RMS ripple voltage not exceeding 10 % of the DC component.
7 Marking and instructions
7.1 Replace the sixth dashed item by the following:
– “Before charging, read the instructions” or symbol ISO 7000-0790 (2004-01); (not required
if the battery charger output is less than 20 VA);
– “For indoor use” or symbol IEC 60417-5957 (2004-12) or “Do not expose to rain” or symbol
IEC 60417-6062 (2011-05); (not required if the battery charger output is less than 20 VA or
the battery charger has a degree of protection against harmful ingress of water of at least
IPX4);
7.6 Add the following symbols to the addition:
[symbol IEC 60417-5957 (2004-12)] for indoor use only

[symbol IEC 60417-6062 (2011-05)] do not expose to moisture

7.12 Replace the first paragraph of the addition by the following:
The instructions shall
– state that during charging, the battery must be placed in a well-ventilated area (for
chargers for batteries that release gases into the atmosphere during normal charging);
– state that the battery charger must only be plugged into an earthed socket-outlet (for
portable class I battery chargers for outdoor use);
– explain the automatic function, stating any limitation (for automatic battery chargers).
The instructions for type 1 battery chargers shall also
– specify the types, the number of batteries and the rated capacity of the batteries that can
be charged;
– include a warning against recharging non-rechargeable batteries.
The instructions for type 2 battery chargers shall also
– specify the batteries intended to be charged, such as by a catalogue number, series
identification or the equivalent;

© IEC 2019
– specify the ambient temperature range for the charger during charging.
Add the following text as a new last paragraph to the addition:
If symbol IEC 60417-5957 (2004-12) or symbol IEC 60417-6062 (2011-05) is used, its
meaning shall be explained.
8 Protection against access to live parts
Add the following new subclause:
8.1.4 Addition:
For type 2 battery chargers, voltages and currents are also measured between relevant
accessible parts of opposite polarity.
10 Power input and current
10.101 Replace the existing text by the following:
The DC output voltage of type 1 battery chargers shall not exceed 120 V. The DC output
voltage of type 2 battery chargers shall not exceed 250 V.
Compliance is checked by supplying the battery charger at rated voltage and measuring the
DC output voltage.
10.102 Replace the existing text by the following:
For type 1 battery chargers, the arithmetic mean value of the output current shall not deviate
from the rated DC output current by more than 10 %.
For type 2 battery chargers, the arithmetic mean value of the output current shall not exceed
the rated DC output current by more than 10 %.
Compliance is checked by connecting the battery charger to the circuit of Figure 101. The
battery charger is supplied at rated voltage and the variable resistor is adjusted to obtain the
rated DC output voltage. The output current is then measured. A battery of the largest
voltage and a battery with the largest capacity (if different) for each battery chemistry may be
used instead of the circuit of Figure 101.
11 Heating
11.5 Delete the modification.
22 Construction
22.26 Replace the requirement by the following:
The output circuit of a type 1 battery charger shall be supplied through a safety isolating
transformer and shall not be connected to accessible metal parts or an earthing terminal.
The insulation between parts operating at safety extra-low voltage and live parts shall
comply with the requirements for double insulation or reinforced insulation.
