Safety Requirements - Electrical safety: Products must not pose risks of fire or electric shock under rated voltage and current [4]. - Mechanical safety: The design must ensure stability and safety during use [4]. - Material safety: Materials used must not harm human health or the environment [4]. Electromagnetic Compatibility (EMC) - Products must undergo EMC testing to ensure they do not generate excessive electromagnetic interference and can withstand interference [5][7]. Environmental Protection Requirements - Compliance with environmental standards during production, use, and disposal is mandatory, including energy efficiency and waste recycling [7]. - Adherence to RoHS standards is required, prohibiting certain hazardous substances in electronic products [7]. EAC Certification Application Process - The application process involves several steps, including confirming applicable technical regulations and selecting the appropriate certification procedure based on product category and risk level [6][8]. - Products must pass tests conducted by accredited laboratories, covering electrical safety, EMC, material safety, and energy efficiency for household appliances [8][9].
