General conditions for the tests
Tests according to this standard are type tests.
Unless otherwise specified, the tests are made on a single toy which shall withstand all the relevant tests. However, the tests of clauses 14, 15, 16 and 17 may be made on separate toys. If the
Unless otherwise specified, the tests are carried out in the order of the clauses.
If a toy is intended to be assembled by a child, the requirements apply to each part available to the child and to the assembled toy. If a toy is intended to be assembled by an adult, the requirements apply to the assembled toy.
13 The tests are carried out with the toy or any movable part of it placed in the most unfavourable position. Detachable parts are removed or kept in position, whichever is more unfavourable.
Toys provided with controls or switching devices are tested with these controls or devices adjusted to their most unfavourable setting, if the setting can be altered by the user.
Detachable cords
Battery toys intended for use with a battery box are tested with the battery box supplied with the toy or with the battery box recommended in the instructions for use.
Battery toys are tested using new non-rechargeable batteries or fully charged rechargeable batteries, whichever is more unfavourable.
When alternative accessories are made available by the manufacturer, the toy is tested with those accessories which give the most unfavourable results.
The tests are carried out in a draught-free location at an ambient temperature of 20
Toys having more than one rated voltage are tested at the most unfavourable voltage.
When testing battery toys, reverse polarity due to incorrect insertion of batteries or to inverted connections is taken into account by repeating the test with the polarity reversed if this is not prevented by the construction.
Batteries are correctly positioned before evaluating the possibility of bridging insulation and before carrying out the short-circuit tests.
14 Before testing is started, the toy is preconditioned by submitting it to the tests of the following subclauses of EN 71-1:
Selection of tests
Toys that comply with the tests of clause 9 with the insulation between parts of different polarity short-circuited are considered to comply with the requirements of clauses 10, 11.2, 12, 15 and 18 and are therefore not subjected to these tests. They ar

Marking and instructions
Toys or their packaging shall be marked with the
15 Toys incorporating detachable lamps shall be marked with one of the following:
16 When symbols are used, they shall be as follows:
Instructions shall be provided which give details concerning cleaning and maintenance when necessary for safe operation of the toy. They shall state that transformers or battery chargers used with the toy are to be regularly examined for damage to the c
17 When markings or instructions are shown on the packaging, the packaging shall state that it has to be kept since it contains important information.
Instructions and other texts required by this standard shall be written in the official language of the country in which the toy is to be sold.
The markings on the toy required by this standard shall be legible and durable.
Power input
Heating and abnormal operation
Toys shall not attain excessive temperatures in use. They shall be constructed so that the risk of fire, mechanical damage impairing safety or other hazards, as a result of careless use or failure of a component, is obviated as far as is practicable.
18 Toys are placed in the most unfavourable position which can occur during play.
Toys are operated under normal operation and the temperature rises of the various parts are determined.
The test of 9.3 is repeated, the insulation between parts of different polarity which is accessible after removing or opening detachable parts being short-circuited. However, the short-circuit is only applied if it is possible to bridge the insulation b
The test of 9.3 is repeated with any control which limits the temperature during the tests of 9.3 and 9.4 short-circuited. If the toy is provided with more than one control, these are short-circuited in turn.

Compliance for electronic circuits
20 During the tests, the temperature rises of accessible parts are monitored continuously and shall not exceed the following values.
Electric strength at operating temperature
Moisture resistance
Battery toys intended to be used in water and toys likely to be cleaned with liquid shall have an enclosure providing the appropriate protection.
21 Toys shall be resistant to humidity.
Electric strength at room temperature
Mechanical strength
22 Construction
Toys shall be constructed to be supplied by a transformer for toys or by a battery having a nominal voltage not exceeding 24 V. They may be constructed to be supplied simultaneously or alternatively by both sources, in which case the supply voltage shal
The transformer of transformer toys shall not be an integral part of the toy.
Toys intended to be used in water shall not be transformer toys.
Toys intended for children under 3 years old shall not be transformer toys.
The resetting of non-self-resetting thermal cut-outs necessary for compliance with this standard, shall require the aid of a tool.
Button cells and type R1 batteries shall not be accessible without the aid of a tool unless the cover of their compartment can only be opened after at least two independent movements have been simultaneously applied.
The batteries of toys intended for children under 3 years old shall not be accessible without the aid of a tool unless
Rechargeable batteries in toys shall not leak, the toy being in any position. The electrolyte shall not become accessible, even if a tool has to be used to remove covers or similar parts.
Toys supplied by batteries connected in parallel are not allowed, unless it is obvious from the construction or from the circuit dia…
Plugs and socket-outlets shall not be interchangeable with plugs and socket-outlets listed in IEC 60083 or with connectors and appliance inlets complying with the standard sheets of EN 60320-1.
23 Non-detachable parts preventing contact with moving parts or hot surfaces, or preventing access to locations where explosion or fire could be initiated, shall be fixed in a reliable manner and shall withstand the mechanical stress occurring during play.
It shall not be possible to charge rechargeable batteries when they are in the toy. However, charging is allowed under the following conditions:
Series motors having a power input exceeding 20 W shall not be used.
Toys shall not contain asbestos.
Protection of cords and wires
Wireways shall be smooth and free from sharp edges.
Bare wiring and heating elements shall be rigid and fixed so that, during play, creepage distances and clearances cannot be reduced below the values specified in clause 18.
Components
Components shall comply with the safety requirements specified in the relevant harmonized standards as far as they reasonably apply.
24 Toys shall not be fitted with:
Transformers for toys shall comply with EN 61558-2-7.
Screws and connections
Fixings, the failure of which may impair compliance with this standard and electrical connections shall withstand the mechanical stresses occurring during play.
25 Torque for testing screws and nuts
Electrical connections carrying a current exceeding 0,5 A, shall be constructed so that contact pressure is not transmitted thro…
Creepage distances and clearances
Minimum creepage distances and clearances (in millimetres)
Resistance to heat and fire
In toys having a working voltage exceeding 12 V and a current exceeding 3 A, external parts of non-metallic material enclosing electric parts and parts of insulating material supporting electric parts shall be sufficiently resistant to heat.
26 Parts of non-metallic material shall be resistant to ignition and spread of fire.
