The former government-supervised
type approval system was replaced by a new safety certification
system overseen by private organizations. The Electric
Appliance Safety Control Act was amended (Act 6019,
proclaimed on September 7, 1999) to enhance safety control
regarding the manufacture and use of electrical appliances
and to harmonize safety requirements with international
standards which will, in turn, facilitate the implementation
of mutual recognition agreements on conformity assessment.The
new law entered into effect as of July 1st in the year
2000. |
|
|
 |
 |
|
Electrical appliances used with supplied input power between
50 VAC and 1000 VAC will be subjected to the certification.

To obtain certification of products, manufacturers of
electric appliances subject to safety certification
(hereinafter referred to as "manufacturers")
shall submit an application to KTL.
Here, manufacturer should be the one who actually produces
the product in his production line. When a product is
manufactured by several independent factories, the certification
shall be issued for each factories although the product
is the same model.
In the case of foreign manufacturers, they have the
option to apply directly or through local agency that
has been authorized with a letter of authorization as
a legal representative for foreign manufacturer.
The application shall be accompanied by the following
documents. Provided, in the case of a derivative model,
the said documents may be omitted if no changes have
been made to the documents submitted for a basic model.
- Application Form
- Product manual (including user instructions)
- Statement of major components, which have direct
effects to electric safety (Table 1, including manufacturers
of components, model, rated and electric characteristics,
etc.)
- Statement on insulating materials (temperature characteristics,
flammability class, etc.)
- Circuit diagram
- Letter of authorization (option for foreign manufacturers)
- Marking plate (draft) : 2 ea.
<Table 1 : Components that have
a direct effect on electrical safety >
Classification |
Scope |
1.
Components used between the primary and secondary
electric circuits and placed in an area that requires
double insulation |
- Transformer
- Relay for electric switch
(including those made of semiconductor materials)
- Optic binding device (photocoupler)
- X Y capacitor to prevent electric shock
resulting from instantaneous voltage excess
|
2.
Components used in an area in which a fire hazard
or insulation problems may arise if the component
is modified |
- Automatic or manual thermostat
(including mechanical and semiconductor circuits)
- Device to prevent excess rise in temperature
- Transformer for high pressure occurrence
(flyback transformer)
|
3.
Components used in an area in which a fire hazard
may arise in case of overload or flow of electric
current over a long period |
- Electric motor
- Magnet clutch, an electrical transformer
that activates according to magnetic
|
4.
Materials used to protect the user from electric,
heat, mechanical, and chemical harm |
- Materials in insulation areas between areas
of alternating current of more than 30V, direct
current of more than 60V and areas that come
into direct contact with the user .
- Materials of exterior that prevent flame
from spreading to outside the product in case
of fire within a circuit
- Materials of areas that prevent mechanical
shock or chemical hazard
|
Remarks:
In the case of a product that has obtained safety
certification manufactured with other components
or materials of same rating, it can be considered
as a change in component of the basic model. Provided,
the transformer is excluded. |
|
|
 |
 |
|
- Initial Factory Inspection : When receiving applications,
KTL shall visit the applicants' factories and verify
their manufacturing and facilities and systems in
accordance with CENELEC CCA-201 procedure (Form MC6/B
& C) prior to granting certification.
Factory inspection will be performed by the certification
body where is related with KTL under MOU.
If an earlier factory inspection of a model of the
same type of product manufactured in the same factory
was conducted, it can be accepted results from the
earlier factory inspection.
- Follow-up Factory Inspection : KTL shall conduct
regular factory inspections once a year per factory
|
|
|
|
 |
 |
|
- When receiving applications for safety certification,
KTL shall conduct testing for safety certification.
- When receiving applications for certification from
foreign manufacturers or their legal representatives,
KTL may issue a sample verification letter to have
the sample pass through customs.
- For compulsory items, KTL shall verify whether or
not the components for the said appliances pertain
to electric appliance subject to safety certification
and whether or not the used components have obtained
safety certification or KS-mark.
In this case, components that fall under any of the
following items shall be accepted as a qualified one.
- A component certified with the relevant IEC
(or EN) standards which KTL has accepted as conforming
to safety standards after having conducted separate
tests on the components.
- A component which has received safety certification
from a foreign certification agency of a country
that has concluded an agreement for mutual recognition
of safety certification that is determined as
a mutually recognized certification agency and
has been publicly notified by the Minister of
Commerce, Industry and Energy and has been accepted
as conforming to safety standards by a domestic
certification agency. In this case, acceptance
is limited to the said product.
|
|
|
|
 |
 |
|
- When the manufacturer wishes to make changes to
details that have obtained safety certification, certification
for the changes shall be obtained before distribution
in the case of domestic manufacturers, while the certification
for the changes shall be receiving before passing
through in the case of foreign manufacturers.
- In the case of a derivative model, manufacturers
may either submit an application for changes to safety
certification together with documents providing evidence
of additional details of the derivative model of the
basic model or submit a new application.
- Manufacturers shall submit an application for changes
to the safety certificate, together with documents
attesting to the said changes, if changes to details
on the obtained safety certificate fall under any
of the following items.
- Changes in business name, trademark, place of
business, and factory site of applicant (includes
manufacturers)
- In the case of seeking double registration of
or changes to control component attached to safety
certificate.
