        NCC certification execution standards for Bluetooth speakers

        In the production and sale of Bluetooth speakers, NCC (National Communications Commission) certification is a crucial step to ensure their legality and security. As short-range and low-power radio frequency devices, Bluetooth speakers need to comply with the LP0002 standard of Taiwan region. The certification process involves rigorous RF performance tests, such as transmission power, transmission bandwidth, transmission channel, occupation time and spurious emissions, to ensure no interference with other wireless systems. Electromagnetic compatibility testing is also a key point to ensure that the speaker does not interfere with other devices during use. Safety testing ensures that the equipment has no electrical or thermal safety hazards.

        How many samples are required for the NCC certification of Bluetooth speakers

        When applying for NCC certification, it is usually necessary to provide one set of normal prototypes, one set of fixed-frequency conduction mode prototypes and one set of fixed-frequency radiation mode prototypes. The normal prototype is used for electromagnetic compatibility testing, while the conducted fixed-frequency prototype is used for routine RF testing, and the radiated fixed-frequency prototype is used for stray emission testing to ensure that the product meets the requirements of RF and electromagnetic compatibility. Preparing these three sets of prototypes is a key step to successfully pass the NCC certification.

        The process for obtaining NCC certification for Bluetooth speakers

        1. Document preparation: Organize product manuals, circuit diagrams, PCB diagrams, lists of key components and other materials;

        2. Sign a contract: Select a qualified testing institution and sign a contract to clearly define the requirements, fees, and rights and responsibilities.

        3. Case Opening Application: Submit the application form and prepared materials. After review by the institution, the case will be opened.

        4. Sample testing: Send the sample machine to the laboratory and complete the testing in accordance with the standards.

        5. Report Review: The laboratory issues the report and submits it for review (checking the process and data compliance).

        6. Certification: The NCC certificate will be issued after the review is passed
