SRRC label

SRRC Certification

Basis for a MII / NAL certification

The SRRC label is primarily a word mark and represents the CMIIT ID, which the manufacturer receives from the authority during the approval process. Here it is important to note that without a CMIIT ID, no product may be imported into China and distributed there.

Core parameters for products with radio technologies

The necessary tests must be carried out in a test laboratory accredited by the Ministry of Industry and Information Technology (MIIT). The authority responsible for this is the State Radio Monitoring and Testing Center (SRTC). Part of the SRRC certification is the determination of core parameters of products with radio technologies. These include among others

  • Frequency
  • Frequency band
  • Transmission power
  • Frequency tolerance
  • occupied bandwidth
  • Parameters of the frequency spectrum (such as out-of-band emissions)

 

Only after a successful SRRC certification an application for a NAL certification can be made, because the test results of a SRRC certification are the basis for a NAL certification.

Products that require SRRC certification include mobile phones (GSM or CDMA), wireless LAN (WLAN) devices, and devices that use the following technologies

  • WLAN
  • Bluetooth
  • ZigbeeWiMAX
  • RFID

 

In the case of SRRC certification, it should be noted that the government body checks the frequencies selected for the product, so the manufacturer is obliged to correctly indicate the frequencies used by the device. Therefore, in order to obtain certification, the transmitting power, bandwidth and stray radiation must meet the requirements of the selected frequencies. In addition, some frequencies are not publicly available in China and manufacturers must also take this restriction into account.

Basic information for SRRC certification

Validity 5 years
Lead time 10 to 12 weeks
Local tests required Yes
Local representative required No
Approval label required Yes

 

In summary, it can therefore be said that manufacturers have to cope with different certification scenarios based on their products and the technologies used there. Here it is advisable to rely on an experienced partner who can already assist in identifying the necessary certification regimes and the relevant scope of testing.
