parts), GB/T 19865, GB 31187 as well as the followings apply.
NOTE: Unless otherwise specified, the terms "voltage" and "current" refer to effective values
(r.m.s.).
3.1 household and similar electrical appliances

power supplies and 480 V for other appliances used by non-qualified person in homes,
residences and similar places (such as shops, light industry and farms).
3.2 electrical parts of sporting goods
Electrical parts of products used in physical education, competitive sports and sports
training, with a single-phase rated voltage not exceeding 250 V and other rated voltages
not exceeding 480 V.
3.3 electric toy
Products designed or intended for children under 14 years of age that require the use of
electricity for at least one function.
NOTE: Transformer toys and power toys are both categories of electric toys.
3.4 rated current
The current specified by the manufacturer for household appliances, the electrical parts
of sporting goods and electric toys.

3.12 supplementary insulation
Independent insulation applied in addition to basic insulation to provide protection
against electric shock in case of failure of basic insulation.
[Source: GB/T 4706.1-2024, 3.3.2]
3.13 double insulation
An insulation system consisting of basic insulation and supplementary insulation.
[Source: GB/T 4706.1-2024, 3.3.3]
3.14 reinforced insulation
Single insulation applied to live parts providing a degree of protection against electric
shock equivalent to double insulation, under the conditions specified in this document.
NOTE: This does not mean that the insulation is a homogeneous body. It may consist of several
layers, but it cannot be tested one by one like supplementary insulation or basic insulation.
[Source: GB/T 4706.1-2024, 3.3.4]
3.15 class 0 appliance
An appliance whose protection against electric shock relies only on basic insulation.
That is, it has no means of connecting accessible conductive parts (if any) to the
protective conductors in the fixed wiring of the installation. In the event of failure of
this basic insulation, the protection against electric shock relies on the environment.
NOTE: Class 0 appliances have either an enclosure of insulating material which constitutes part or
all of the basic insulation, or a metal enclosure separated from live parts by suitable insulation. If an
appliance with an enclosure of insulating material has provisions for grounding internal parts, it is
considered to be a class I appliance, or a class 0I appliance.
[Source: GB/T 4706.1-2024, 3.3.7]
3.16 class 0Ⅰ appliance
An appliance having at least basic insulation as a whole and having a grounding
terminal, but its supply cord does not have a grounding conductor and its plug does not
have a grounding pin.
[Source: GB/T 4706.1-2024, 3.3.8]
3.17 class Ⅰ appliance
The household appliances and the electrical parts of sporting goods whose protection
against electric shock not only relies on basic insulation but also includes an additional
safety protection measure. The protective measure is to connect the accessible
conductive parts to the protective grounding conductor in the fixed wiring of the facility
so that in the event of basic insulation failure, the accessible conductive parts will not
be energized.
NOTE: This protection includes a protective earth conductor in the power supply cord.
[Source: GB/T 4706.1-2024, 3.3.9, modified]
3.18 class Ⅱ appliance
The household appliances and the electrical parts of sporting goods whose protection
against electric shock not only relies on basic insulation, but also provides additional
safety protection measures such as double insulation or reinforced insulation. This kind
of household appliances and the electrical parts of sporting goods does not have
protective grounding or measures that rely on installation conditions.
NOTE 1: The This kind of appliance may be of one of the following types.
- An appliance having a durable and substantially continuous casing of insulating material which
encloses all metal parts except small parts such as nameplates, screws and rivets. The
enclosure provides protection at least equivalent to reinforced insulation to isolate these small
metal parts from the live parts of the appliance. This type of appliance is called a class II
appliance with an insulating enclosure.
- An appliance having a substantially continuous metal enclosure in which double insulation or
reinforced insulation is used throughout is called a class II appliance with a metal enclosure.
- An appliance that is a combination of a class II appliance with an insulating enclosure and a
class II appliance with a metal enclosure.
NOTE 2: For class II appliances with insulating enclosures, the enclosure may constitute part or all
of the supplementary insulation or reinforced insulation.
[Source: GB/T 4706.1-2024, 3.3.10, modified]
3.19 class Ⅲ appliance
The household appliances and the electrical parts of sporting goods that rely on safety
extra-low voltage to provide protection against electric shock and the voltage they
produce is not higher than the safety extra-low voltage.

NOTE 1: Any accessible or inaccessible parts that meet the requirements of 8.1.4 in GB/T 4706.1-
2024 are not considered to be live parts.
NOTE 2: A PEN conductor is a protective earthed neutral conductor that combines the functions of
both a protective conductor and a neutral conductor.
