Radio Frequency Testing

With the rapid advancement of wireless communication technology, SRRC (State Radio Regulatory Commission) certification has become an essential requirement for radio equipment to enter the Chinese market. However, faced with complex certification processes and constantly updated standards, many manufacturers often encounter various challenges when applying for SRRC certification. This article will reveal common misconceptions about SRRC certification and provide a pitfall avoidance guide distilled from years of SRRC certification experience, helping you successfully pass SRRC certification and quickly bring your products to market.

01. Conduct IPv6 Testing to Avoid Market Inspection Risks

Effective October 13, 2023, SRRC mandates IPv6 testing for wireless LAN products (such as routers, servers, switches) that connect to public networks and feature DHCP allocation functionality. (DHCP is a LAN protocol primarily responsible for rapidly and automatically assigning IP addresses.)

If your product obtained SRRC certification before this date but lacks IPv6 testing, promptly complete the required tests to avoid penalties during market inspections.

02. Monitor Standard Updates to Ensure Certificate Validity

If your product applied for SRRC certification under the old standards before October 15, 2023, please note: Certificates issued under the old standards will uniformly expire on December 31, 2025. (Old standards refer to: MIIT [2002] No. 353, MIIT [2002] No. 227, MIIT [2002] No. 620) To maintain certificate validity, renewal must be completed before December 31, 2025.

Certificates obtained under the new standards are valid for 5 years.

03. Challenges and Countermeasures Under the New Standard

The implementation of the new standard imposes stricter requirements on SRRC certification, with the most significant change being the addition of interference avoidance testing. To ensure products pass testing smoothly, manufacturers are advised to incorporate interference avoidance mechanisms during the product design and development phase and conduct pre-screening tests at professional testing institutions to improve first-pass testing success rates.

04. Reducing Failure Rates in Interference Avoidance Testing

Interference avoidance testing is one of the most challenging aspects of SRRC certification. Also known as detection and avoidance, this test evaluates whether a device's transmitter can switch channels when encountering interference. To improve pass rates, manufacturers should thoroughly consider interference avoidance mechanisms during product design and incorporate corresponding software settings. Additionally, selecting professional testing institutions with pre-scan capabilities for preliminary testing is an effective method to enhance pass rates.

Note: Products below 10dBm are exempt from testing.

05. Certification Requirements for Products with Built-in Wireless Modules

If your product incorporates a wireless module already certified by SRRC, does the entire device still require certification? This depends on whether your product falls under the “Information Technology Equipment and Household Appliance Equipment” product catalog. If included, you may utilize the wireless module's certification results and supplement with radiation/spurious emission testing. If excluded, full testing and certification of the complete device is required.
