Overview
Safety Certification
It tests the electrical appliance’s compatibility according to the safety standards as well as inspects the factory to confirm the manufacturer’s capability to maintain the quality of electrical appliance, verifying the safety of electrical appliances before being distributed to the market.
Periodic Inspection
It is a follow-up system by the safety certificate authority to ensure the safety of certified products continues to be maintained, conducting factory inspection and product test once a year, and amongst certified models, one product from 11 product categories is tested. (The manufacturer is responsible for paying the cost of periodic inspection)
Electrical Appliances Safety Control Act and Related Law
For safety management system for electrical appliances, Electrical Appliances Safety Control Act is amended (Effective on July 31, 2014) ？ an advanced safety management system that is divided with a mandatory safety certification and safety confirmation report depending on the risk degrees, and amongst electrical appliances with low risk of safety can be designated as items to declare the supplier’s conformity, to self-check and self-report the safety, and to sell the products.
Periodic Inspection
When the products have gone through tests by safety certificate authority and satisfied the safety standards, the manufacturers and importers can report them to the safety certificate authority and sell them. This eliminates the periodic inspection process (factory inspection + product test) of once a year that previously existed during safety certification procedure. However, the safety check and report expires after five years.
Supplier’s Declaration of Conformity System
Manufacturers or importers self-confirm or have a third party confirm the safety of products and mark the conformity with the safety standards
1. Manufacturers or importers of electrical appliances, which are applicable for the confirmation of supplier compatibility, comply with ordinance of Korean Agency
for Technology and Standards, and self-test or have a third party test models of electrical appliances, which are applicable for the confirmation of supplier
compatibility, and to confirm that the products satisfy Item 2 of the safety standards. (Hereinafter referred as “Supplier’s Declaration of Conformity”)
2. Supplier’s Declaration of Conformity shall be in accordance with Item 2 of Article 11 of safety standards.
3. After the manufacturer or importer confirms the supplier’s declaration of conformity for electrical appliances, they will comply with Item 2 of safety standards
by Korean Agency for Technology and Standards.

Note
What is the basic model?
It refers to the model(s) of electrical appliances with standard safety certification which the electrical appliances have the same parts that directly affect the safety applicable standards and their safety.
What is the derivative model?
Compared to the basic model, the basic structure related to electrical circuits and safety are the same as the basic model, but the parts of these models that directly affect electrical safety do not change while additional functions are added or deleted (including a change in electrical circuit that does not directly affect electrical safety) or the shape or trademark is changed.

Procedure of Safety Certification
Procedure for Voluntary Safety Confirmation
Procedure of Safety Certification
It shall be conducted inside Korea Testing Laboratory. (It can be done at manufacturing sites for the following cases)
- When the samples are so heavy or large that they cannot be delivered to the certifying authority (applied when appropriate testing equipment is available at the site or can be delivered to the site)
- When the factory is the only one that is equipped with testing equipment for the product test
Factory Inspection
In order to obtain the safety certification, an initial (preliminary) factory inspection must be done before obtaining the certification, and the periodic inspection shall be conducted once a year after obtaining it.
Procedure for Supplier’s Declaration of Conformity
When you apply for Electrical Appliances Safety Certificate with KTL, you will receive the following benefits.
You can obtain a certificate of international well-known certificate authorities
You can enjoy the one-stop service and receive certificate marks such as VDE, NEMKO, KEMA, JET, JQA, PSB, IRAM, etc. under MOU in the fastest way without duplicate tests.
You can obtain an international certificate (CB certification) at the same time
As Korea’s only international certificate issuing organization, KTL issues the safety certification and CB certification for main electrical appliances at the same time. (Additional fee) CB certification permits you to achieve certifications from 43 countries around the world. (http://www.cbscheme.org)
You can save time and cost as the factory inspection is conducted on site
The manufacturing plants in foreign countries can be inspected by local certificate authorities that have signed an agreement with KTL; therefore, it is easy, fast, and affordable to obtain safety certification. Your test report of foreign certificate authority is useful.
Your test report of foreign certificate authority is useful.
When applying for the safety certification, if you have test results by IECEE-CB system or a test report issued by foreign authorities that have a mutual agreement with KTL, those test reports will be used 100%.
You can simultaneously request KS certification test and administrative multifunctional office supplies test.
As KTL is designated as KS inspection authority of electrical appliances and Ministry of Security and Public Administration’s multifunctional office supplies testing lab, you can avoid duplicate tests.
