What is SRRC Certification?
SRRC certification is a mandatory certification for radio frequency devices in China, and all radio frequency components sold or used in China must obtain a radio frequency model approval certificate.
Importance of SRRC Certification
SRRC certification is a mandatory certification for wireless transmission equipment, mainly testing RF parameters such as power, frequency range, frequency tolerance, bandwidth, and spurious emissions. Only certified products can be legally sold and used in the Chinese market.
Devices that obtain SRRC certification can ensure that their radio frequency emissions comply with Chinese radio management regulations, preventing harmful interference with other radio services and ensuring the effective utilization of radio frequency spectrum.
SRRC Certification Process
Application Acceptance
Submit SRRC certification application to the State Radio Monitoring Center.
- Fill out the Radio Frequency Device Model Approval Application Form
- Provide the business license of the applying unit
- Provide the technical specification book of the equipment
- Provide the circuit diagram and block diagram of the equipment
- Pay the application fee
Technical Review
Technical review of the application materials to confirm that the product meets the application requirements.
- Review product technical parameters
- Confirm compliance with frequency usage
- Check completeness of application materials
- Develop testing plan
Sample Testing
Radio frequency emission testing is conducted at a designated testing institution.
- RF Power Testing
- Frequency Range and Frequency Tolerance Testing
- Bandwidth Testing

Notes
Important Reminders
- SRRC certification is a mandatory certification, and radio frequency devices must obtain certification before sale
- The发射功率、频率范围等射频参数 must be in compliance with Chinese radio management regulations
- When applying for certification, ensure that the product is finalized to avoid design changes later
- Test sample machines should be consistent with mass production products
- Certified products should mark the SRRC certification number on the product label
- Product design changes may require re-applying for certification
- Monitor related regulatory updates to ensure ongoing compliance
