China Wireless Product Certification(SRRC)

  Products with wireless functions are becoming more and more common due to the integration of wireless modules like Bluetooth, WiFi, and Zigbee, among others. Entering the Chinese market with a wireless product requires the mandatory certification: SRRC, and an NAL certification for telecom equipment.

  State Radio Regulatory Commission (SRRC)

  The SRRC is the certification body responsible for the mandatory SRRC certificate. Unlike China Compulsory Certification (CCC), there is no product category for SRRC; therefore all types of products, whether industrial or residential, must be SRRC-approved if they have radio transmitter function. In addition, SRRC is type approval, meaning each model needs to be tested and certified. (One exception to this is module approval, which allows for application as a product series.)

  Certification Process

  In order to obtain SRRC certification, manufacturers must:

  Submit an application to SRRC

  Send samples to an accredited local test lab in China

  Receive type approval certificate (after the product has been successfully tested and SRRC reviews the test report)

  Testing generally lasts one week if there are no product issues, and the review process lasts approximately four weeks. SRRC approval does not require a factory inspection, but the manufacturer must have an ISO9001 quality control system or similar procedures to ensure quality standards are met. Once testing has been completed successfully, the SRRC will issue the certificate with CMIIT ID, which must be added to the product nameplate to show compliance.

  Preparing Samples

  Conducted emissions will be tested during the SRRC approval process, so the manufacturer must prepare samples with conductive terminals to connect to the testing equipment. If the RF module does not function continuously during testing, the manufacturer must configure the sample to force the module to work under different modes, such as modulation mode at different frequencies with different transmission speeds, carrier wave only, etc.

  General Requirement

  Frequencies are controlled by the Chinese government, so manufacturer must design or choose the proper frequencies to use. In order to gain approval, the transmit power, bandwidth, stray radiation, and more must meet the requirements of that specific frequency. In addition, some frequencies are not open to the public, so manufacturers must ensure their frequency is appropriate before applying.
