Managing Dual Band Radio Laboratory Testing under Chinese Regulatory Frameworks
SRRC approval for dual-band radios demands locked firmware power tables, local agent coordination, and strict host radiated spur compliance to avoid re-test delays.
CCC Certification Overlap
Meaning
Regulatory conformity frameworks in China require certain categories of electronic products to obtain a China Compulsory Certificate before they can be imported or sold. When a smart device incorporates a pre-certified wireless module, ccc certification overlap occurs, creating a scenario where both the host system and the module are subject to separate but intersecting safety and electromagnetic compatibility evaluations. Navigating this scenario requires a clear division of testing responsibilities to avoid redundant evaluations of the internal components.
Regulatory Assessment
National standards define the test requirements for both modules and complete systems. The host evaluation typically focuses on the power supply and system-level radiated emissions. Pre-existing modular certificates can be used to simplify the certification process for the host, provided the module is integrated according to the manufacturer’s guidelines.
Integration Impact
Hardware developers must verify that the operating environment of the host does not exceed the thermal and electrical limits specified in the module’s certificate. Changes in the power delivery circuitry can void the existing module-level compliance. This requires a re-evaluation of the radio characteristics if the supply voltage is unstable.
Exemption Rule
Technical documents submitted during the application process outline the components that do not require re-testing. Some subassemblies are exempt from duplicate safety tests if they hold a valid certificate of their own. This exemption streamlines the final approval phase for complex connected devices.
