Radio Frequency Testing

I. Overview of SRRC Certification

SRRC certification (State Radio Regulation Committee) is a mandatory approval certification for radio transmitting equipment in mainland China, regulated by the State Radio Regulatory Commission. All radio transmitting equipment sold or used within China (such as Bluetooth devices, Wi-Fi modules, walkie-talkies, IoT terminals, etc.) must obtain SRRC certification and affix the model approval code.

II. Complete Process for Obtaining SRRC Certification

1. Application Submission
    Submit the “Radio Transmitting Equipment Model Approval Application Form” to an officially authorized laboratory.
    Provide complete technical documentation: product manual, circuit schematic, RF parameter table, etc.

2. Sample Preparation
    Provide complete unit samples meeting testing requirements (typically 5 units).
    Clearly label each sample with the product model and serial number.

3. Testing Phase
    Complete the following tests at an SRRC-accredited laboratory:
        Frequency range and tolerance testing
        Transmission power and power spectral density
        Occupied bandwidth and spurious emissions
        RF exposure safety assessment
    Testing cycle typically takes 15-20 working days

4. Report Review
    Laboratory issues a CNAS-accredited test report
    Submit the report to the National Radio Monitoring Center for review

5. Certificate Issuance
    Upon approval, the Radio Transmission Equipment Model Approval Certificate is issued.
    Certificate validity: 5 years (renewal application required 3 months prior to expiration).

6. Post-Certification Management
    Certified products must clearly display the CMIIT ID approval code on their exterior.
    Technical parameter changes require reapplication for approval.
