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.

  1. Application Form
  2. Product manual (including user instructions)
  3. Statement of major components, which have direct effects to electric safety (Table 1, including manufacturers of components, model, rated and electric characteristics, etc.)
  4. Statement on insulating materials (temperature characteristics, flammability class, etc.)
  5. Circuit diagram
  6. Letter of authorization (option for foreign manufacturers)
  7. 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.
 
 
  1. 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.
  2. Follow-up Factory Inspection : KTL shall conduct regular factory inspections once a year per factory
 
 
 
  1. When receiving applications for safety certification, KTL shall conduct testing for safety certification.
  2. 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.
  3. 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.
    1. 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.
    2. 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.
 
 
 
  1. 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.
  2. 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.
  3. 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.
    1. Changes in business name, trademark, place of business, and factory site of applicant (includes manufacturers)
    2. In the case of seeking double registration of or changes to control component attached to safety certificate.
