KC authentication overview
Electrical appliances safety certification system is based on electrical appliances Safety Management law enforcement and self-discipline (voluntary) safety certification certification system, is to obtain safety certification manufacturing / sales system.
Apply for security certification object is:
Domestic and foreign production of electrical products, assembly, processing all enterprises (legal persons or individuals).
Security certification system and method are:
The product model is applied for certification and is divided into basic models and derived models
In order to differentiate the design of models and electrical appliances, the product names are given according to the functions of the products which are different from each other.
The basic model is:
In the electrical application of basic circuits and electronic safety applicable to the basic structure of similar models of electrical appliances, the use of standard products for safety certification.
Derived model:
The core circuit related to authentication needs to be the same as the basic model. The same components and similar products do not affect the electrical certification directly.
The distinction between compulsory certification and self regulatory (voluntary) security certification is that:
Compulsory certification means: all electronic products belonging to mandatory products must be KC Mark certified before they can be sold in the Korean market. Each year, factory inspection and product sampling test are required.
Voluntary (voluntary) certification means that all electronic products belonging to a voluntary product only need to be tested for certificates and do not need to be examined by the factory. The certificate is valid for 5 years.
Certification mark and indication - KC certification mark (the same mandatory and self-discipline)

 KC certification is based on the size of the product changes
KC certification mark is a sign of the products or containers and packaging is easy to distinguish, printed or engraved adhesion is not easy to fall off for signs.
- adjacent to the KC certification cover, indicating the KC certification number. Other matters relating to the safety standards of the Chinese English or postscript etc.
- KC certified. The cover color is marked black

 Applicant (or agent) submit the product information
At the time of the new application, the certification process generally includes the following
(1) application form: electrical appliance safety certification application (compulsory product), electrical appliance self regulatory safety confirmation application and electric appliance self regulatory safety declaration (self controlled product);
(2) model differences (for multiple models)
(3) circuit schematic diagram and PCB LAYOUT
(4) list of key originals and relevant certification;
(5) transformer and inductance specification (English)
(6) product frame drawing;
(7) power of attorney
(8) ID application form;
(9) tag (Marking, Label)
(10) product manual (Han Wen)
If a product is produced by several independent factories, several products should be certified at the same time, even though the product is of the same model. Overseas manufacturers may apply directly or authorize local agencies and representative factories in korea.

Factory review
The Korea Security Act provides for the first factory review of the plant after acceptance of the application.
In accordance with the requirements of the safety law, a preliminary assessment of the quality control system of the plant is carried out, with the following aspects covered:
The factory shall produce the certified products consistent with the certification bodies' approved samples according to the product certification, implementation measurements and plant quality assurance requirements. According to South Korea's security certification related laws and the Korea Industrial Technology Research Institute (KTL) of the relevant provisions, your factory should have the following documented procedures or regulations, the content should be commensurate with the quality management and product quality control:
1) product change control procedures
(for example: certified products get certification declaration of change after the approval department should should be strictly in accordance with the content of the changes approved formulation of the related technical documents issued to the relevant departments to correctly implement certification product changes. An unauthorized change may not apply a certification mark on the change of the product. )
2) document and data control procedures
3) the quality record control procedure shall include the record keeping period of at least 3 years (just stock, routine and running inspection records)}
4) routine inspection and verification procedures
5) nonconforming product control procedures
6) inspection and verification procedures for key components and materials
7) internal quality audit procedure
8) procedures, guidelines, inspection standards, instruments, equipment, operating procedures, management systems and other procedures
The factory shall keep at least the following quality records to verify that the factory has undergone all production inspections and production tests, and that the quality records shall be authentic and valid:
9) routine inspection and confirmation of inspection records:
Key components and materials incoming inspection / verification record and supplier's qualification certificate
Records of calibration and verification of inspection and test equipment on a regular basis;
Routine inspection and confirmation (running) inspection record
Daily inspection record of safety equipment on production line (workshop)
Disposal records of nonconforming products (stock, routine and operation);
Records of internal audits;
The customer complaint records to take corrective measures;
The operation inspection unqualified corrective records;
Annual factory review:
After the authorization of the certificate, the certification authority will conduct an annual review of the factory each year. The main purpose is to check the consistency of the quality control system of the factory and whether it can continue to comply with the standards of safety law.
The annual Factory review is divided into two parts:
1) the quality, documentation, quality records, and relevant content of the manufacturing site are reviewed, and the requirements and contents are basically the same as those of the initial review.
2) the need to confirm the consistency of all products obtained by the KC Mark authorization within the factory. Confirm the key components, materials, circuits, structures, etc. of the certified products according to the certificate of authorization (list of key components), and see if they are consistent.
Sampling requirements:
Products included in the KC Mark compulsory certification range, so far, there are 216 kinds, the South Korean Security Act provides for the annual sampling of all kinds of products, so each product has a sampling every year.
Sampling method:
By the factory inspector at the time of the annual review, where the production or stock is in place, the examiner will seal the sample and send the sample to the assigned address within 3 months. When the factory does not produce or store the goods at the time of inspection, the factory shall send the sample to the designated address within 6 months
Brief introduction of KTC and KTL testing organization
KTC and KTL are the certification bodies designated by the Korea Institute of technology standards, which can issue KC mark certificates, as well as the testing organizations of products.
(1) Korea Institute of mechanical and electrical and electronic test (KTC Korea Testing Certification) KTC was established in 1970, is Korea's official professional testing institute. In the past few years, the Institute has been working on technical evaluation, suitability testing, calibration, inspection and testing of medical equipment and information and communication equipment.
In 2000, the Institute was designated as the safety certification body for electrical appliances, and in 2003 it became the CB laboratory designated by the International Electrotechnical Commission (IEC).
In order to meet the needs of Chinese and Korean customers, KTC set up branches in Shenzhen and Shanghai. KTC's official website has three versions: Korean, English and chinese.
(2) Korea Institute of industrial technology inspection (KTL);
KTL, founded in 1966, is a testing and evaluation organization established to support industrial technology through support for testing and evaluation technology. In order to improve all kinds of certification system to promote its industry, to protect consumer safety and environment, KTL provides support for the product development to the stage to obtain certification, to help enterprises to improve technological ability and enhance competitiveness.
In addition, KTL or advanced (developed) testing and certification organizations of the state of the Korean people exchanges and cooperation mechanism, the 67 test certification agencies and 35 countries have signed a memorandum of cooperation (MOU), 43 specifications in 9 areas issued CB certificate and test report.
In view of electronic and electrical communication products and components, the hospital can be tested and evaluated in the field of safety, electromagnetic compatibility and reliability evaluation.
