Proposal for legal inspection requirements for wireless chargers (4 page(s), in English; 3 page(s), in Chinese)
Wireless chargers are widely used to charge electronic devices, such as tablets or mobile phones. A survey of such products raised safety concerns in aspects of overheating, fire-resistance and others. In order to protect consumers from relevant hazards arising from the use of such products and to protect the environment, the Bureau of Standards, Metrology, and Inspection (BSMI) proposes to regulate the safety, EMC, and hazardous substances of wireless charger products. The inspection standards are CNS 14336-1 for safety, CNS 13438 for EMC, and Section 5 of CNS 15663 for marking of the presence of six hazardous substances, including Lead (Pb), Mercury (Hg), Cadmium (Cd), Hexavalent Chromium (Cr+6), Polybrominated Biphenyls (PBB), and Polybrominated Diphenyl Ethers (PBDE). Where the main working frequency of the wireless chargers is less than 30MHz, they shall also comply with the magnetic field radiation requirements of CNS 13803 (2003). The conformity assessment procedure shall be Registration of Product Certification (Module II Type Test + Module III Conformity to Type Declaration).
