SRRC Certification

SRRC is the wireless transmission certificate issued in China by the State Radio Regulatory Commission.

SRRC is mandatory certification for wireless products sold and used in China. Equipment and appliances that have radio transmitting functions like WLAN, Bluetooth, Zigbee, GSM, WCDMA, LTE, radar and broadcasting, etc. must apply for SRRC type approval. SRRC will issue the type approval certificate after the product passes testing and will assign a CMIIT (China Ministry of Industry and Information Technology) number for the model.

General information for SRRC certification:

  • Mandatory certification for wireless products sold in China
  • Testing must be conducted in China in accredited labs
  • The certificate is valid for 5 years (can be extended)
  • No factory inspection required
  • No local representative needed

 

Module approval is applicable for SRRC. An end product using the approved module can exempt some testing if the module is operated independently.

SRRC process

Generally, SRRC as type approval means each model needs to apply for SRRC certification. However, for certain products, if multiple models use the same RF module, serial certification is applicable.

SRRC requires local testing in China in accredited labs. Manufacturers need to send test samples to China for testing. We can help in customs clearance for test samples if needed. Test sample requirements can be found below. If the end product is too big to send or it is not possible to set test parameters, you can send modules with a test board. We can help you set up testing on-site to support the test.

Test sample preparation:

  • Conducting testing on test samples is required: You can use an SMA connector cable to connect with a spectrum analyzer

    Or use a test board to setup the parameters
  • Make sure the test sample can send signals continuously
  • Frequency/channels should be changeable by commands or software
  • Carrier wave mode must be tested
  • Provide the antenna gain

 

Common test items:

  • Frequency range
  • EIRP (equivalent isotropic radiated power)
  • Maximum power spectral density
  • Frequency tolerance
  • Occupied bandwidth
  • Stray emission

 

SRRC has some special test set-ups for different RF functions like WLAN, Bluetooth, WCDMA, etc.

WLAN product SRRC test requirements

Test items:

  • Effective Isotropic Radiated Power
  • Maximum power spectral density
  • Frequency tolerance
  • Frequency range
  • Occupied bandwidth
  • Spurious emission
  • If the equipment supports the 5250-5350 MHz frequency band emission, DFS items shall be tested.
