Expert interpretation丨Safety CB to South Korea KC, these matters should be paid attention to

Date：2022/8/16　　Clicks：1159

At present, when many companies apply for the Korean safety KC certification, most of them choose to pass the CB certificate and report to KC (this method can be subdivided into two types: ordinary CB mode and MOU mode). The author has passed the KC certification practice in recent years. Based on our experience, we have summarized the following points for attention when applying for CB to KC for the first time, for the reference of business friends in need.

Note: The MOU model is a convenient forensics model based on CB (not limited to CVC Weikai), which is applicable after the Chinese certification body (such as CVC Weikai) and the Korean certification body sign the MOU mutual recognition agreement under the bilateral mutual recognition framework between China and South Korea. .

The main difference from the ordinary CB model is that there is no need to send samples to Korea, and the certification cycle can be greatly shortened.

Note: The picture above is an attachment to the KC application form of a Korean certification body, including the MOU mode option.

01 The name and address of the factory must be included on the CB certificate and report

If the KC certification is held by a factory as the applicant (KC applicant can be a factory or a Korean importer), the KC applicant must be consistent with the name and address of the factory on the CB. In principle, the factory address should be the registered actual production address.

02 The CB certificate and report must include the product model applied by KC

When there are multiple series models on the CB, one of the models can be the same as the KC application model. However, it is not possible to divide the KC certification unit or determine the main KC model by the series model on the CB. It is necessary to divide the KC certification unit and determine the main model and derivative model according to the regulations of the Korean Electrical Appliances Safety Management Law. That is to say, CB is a certificate, which does not mean that KC can also be a certificate.

03 Need to confirm the test standard adopted by CB (including version)

If only the standard version of CB and KC is different, it is recommended to update the CB to ensure consistency with the KC standard. If the CB standard used by the product is different from the KC standard number, it needs to be confirmed with the Korean certification body.

Example: For lithium battery products, starting from January 2021, South Korea will only accept applications for the KC 62133-2: 2020 version, which corresponds to IEC 62133-2: 2017.

For IT/AV products, the standard has been merged from K60950-1, K60950-22 and K60065 to KC 62368-1, from December 31, 2022, only CB certificates of IEC 62368-1:2018 (3rd edition) are accepted and report to KC.

04 The CB test report needs to include Korean national differences, and the voltage and frequency must meet the Korean requirements

For example: if the appliance is powered by the city network, the single-phase appliance must include 220V~, the rated frequency must include 60Hz, the three-phase appliance must include 380V~, and the rated frequency must include 60Hz.

05 Component control requirements

(1) The key components belonging to the KC certification object must be tested by IEC standards in CB or obtained KC certification

The parts list of the CB report must include the parts used in the products applying for KC. If the key parts in the CB report are the object of KC certification, the parts must be tested according to IEC standards or have KC certification. Standards are not recognized, such as EN, DIN, UL, GB, BS, etc.

Example:


 If the above conditions are not met, it can be replaced by random testing of components (only applicable to non-Korean manufacturers).

(2) The key parts list of KC only needs to reflect the parts specified by KC, and some parts in the CB report, such as internal wires, varistors, etc., do not need to be reflected in KC.

(3) When applying for KC, it is necessary to provide certificates for key components, such as KC certificates for plugs and power cords; specifications for motors (if any) and transformers (if any) are required.

06 Need to confirm the country differences of key parts (such as plug size)

The plug size in Korea is based on KS C8305, and the plug must have KC certification.

07 KC forensics cycle in CB mode

Under normal circumstances, ordinary CB mode: the cycle of transferring to KC is generally 5-8 weeks (generally, samples need to be sent to South Korea for verification). If random testing of parts is required, the time will be calculated separately.

MOU mode: Apply through a Chinese certification body (such as CVC Weikai), usually 2-4 weeks (free samples to South Korea).

08 Information needed to convert CB to KC

Application, business license, list of key parts, Korean nameplate, Korean manual, CB report and certificate, circuit diagram, PCB diagram, specification (transformer/motor, heater), factory survey form, model difference description table, etc.
