Documents to be submitted for authentication

    If a company needs to apply for the KC mark, it must first apply to the Korea Electrical Testing Institute (KETI) or the Korea Testing Laboratory (KTL). If a product is produced by several independent factories, even though the product is the same model, several factories should obtain the certification mark at the same time. Overseas manufacturers can apply directly or authorize local agencies in South Korea to apply on behalf of manufacturers.

    The following documents need to be submitted when applying for KC certification for new products:

Application for safety certification of electrical appliances (mandatory products), application for self-regulatory safety confirmation of electrical appliances and self-regulatory safety confirmation statement of electrical appliances (self-regulatory products);

A list of parts that directly affect safety;

Electrical circuit diagram;

Transformer specifications (where relevant);

Insulation material list (temperature, pressure resistance or fire resistance grade, etc.);

Product certificate (including Korean product certificate);

Tags;

Agent authorization certificate (required for mandatory products; It is necessary for self-regulated products to be applied by agents);

Questionnaire survey (mandatory product).

 

Factory review

    (1) First factory review

    After receiving the application for product certification, KTL is required to conduct the first factory audit of the plant and conduct a preliminary evaluation of the quality control system of the plant. In accordance with Korean safety certification laws and KTL regulations, the factory shall have the following documented procedures or regulations, which shall be compatible with factory quality management and product quality control:

    (1) Product change control procedures (example: After the certification body approves the change declaration of the certified product, the corresponding technical documents shall be formulated in strict accordance with the approved change content and placed in the relevant departments to correctly implement the change of the certified product. A certification mark cannot be applied to the changed product without approval.) ;

    (2) Documentation and data control procedures;

    (3) Quality record control procedures (purchase, routine and operation inspection records are kept for at least 3 years);

    (4) Routine inspection and confirmation inspection procedures;

    (5) nonconforming product control procedures;

    (6) Inspection or verification procedures for key components and materials;

    (7) Internal quality audit procedures;

    (8) Process operation instructions, inspection standards, instrument and equipment operating procedures, management systems and other procedures, the factory shall keep at least the above quality records to confirm that the factory has indeed carried out all production inspections and production tests, and the quality records shall be true and effective;

    (9) Product routine inspection and confirmation inspection records; Incoming inspection/verification records of key components and materials and conformity certificates from suppliers:

    ① Records of regular calibration or verification of inspection and testing equipment;

    ② Routine inspection and confirmation (operation) inspection records;

    ③ Daily inspection records of safety equipment on the production line (workshop);

    ④ Disposal records of nonconforming products (purchase, routine and operation);

    ⑤ Record of internal audit;

    ⑥ Records of corrective actions taken in response to customer complaints;

    ⑦ Corrective record of unqualified operation inspection;

    (2) Annual Factory Review

    After the certificate is issued, the certification body will conduct an annual follow-up review of the factory, the purpose is to review the consistency of the factory's quality control system, whether it can continue to meet safety standards. The annual Factory review is divided into two parts:

    (1) The requirements and contents of quality documents, quality records, and relevant content of the production site are basically the same as those of the first review.

    (2) It is necessary to confirm the consistency of all products authorized by the KC mark in the factory. According to the attached page of the product's authorization certificate (key components list), confirm the key components, materials, circuits, and structures of the certified products to see whether they are consistent.

    (3) Sampling inspection

    A total of 216 products are included in the mandatory certification of the KC mark. The Korean Safety law requires that all types of products be sampled annually, so each product is sampled once a year. The sampling method is: by the factory inspector during the annual review, when there is production or inventory on site, the inspector seals the sample, the factory will send the sample to the designated place within 3 months; If there is no production or stock at the time of the factory audit, the factory must send the designated sample to the designated location within 6 months.
