Audio CCC certification——ZRLK

Author:中認(rèn)聯(lián)科 time:2020-12-15 Ctr:1224

Does the audio need to be CCC certified?

The 8th category of the CCC product catalog, "Audio and Video Equipment" 0801 sub-category, stipulates that "single-speaker and multi-speaker active speakers with total output power below 500W (effective value)" (ie audio) need to apply for CCC compulsory certification. That is to say, speakers with a total output power of <500W are products within the scope of the 3C certification product catalog and need to be CCC certified.

For specific information, please consult the sales engineer who handles testing and certification for enterprise products.

2. Product testing

The enterprise pays the test deposit, and ZRLK accepts the test application. Enterprises need to provide effective product samples. If the test fails, ZRLK will issue a rectification opinion, and the company will rectify the product until the product meets the CCC certification standards.

3. Factory inspection

The factory is the guarantee of product safety and needs to be kept clean and tidy. CCC factory audit personnel will verify the relevant information of the company, which is mainly divided into information review and quality review.

4. Issuing a certificate

The company has passed the audit and obtained the corresponding CCC certification.

5. Annual factory inspection

CCC certification will conduct a supervision and inspection of the factory once a year. If the inspection fails, the company will be punished accordingly.
