Electrical Safety Standards for China Electronics
4 resources tagged with "Safety"
Product safety for electronics sourced from China hinges on the right standard for the product class: IEC 60335 for household appliances, IEC 62368-1 for IT/AV equipment, UL 217 for smoke alarms, and EN 14604 for residential CO/smoke detectors. The distinction that trips up buyers is UL Listed vs UL Recognized — a Recognized component mark does not make a finished product safe to sell. For life-safety devices like smoke and CO detectors or TPMS sensors, the certification isn't optional marketing; it's what stands between you and product-liability exposure.
Sourcing to a safety standard means matching the device to the correct IEC/UL/EN standard and verifying a full-product certificate, not a component or self-declared one. The pitfall is accepting a UL Recognized component mark as proof the finished product is certified.

FAQ
What's the difference between UL Listed and UL Recognized?
UL Listed means the complete end product passed UL's safety evaluation and can be sold as certified. UL Recognized applies to a component intended for use inside another product, and does not certify the finished device.
Which safety standard applies to a smoke detector from China?
For the US market, UL 217 (current 8th edition) governs smoke alarms; for Europe, EN 14604. A combo smoke/CO unit also needs the relevant CO standard. Confirm the certificate covers the finished, branded product.
How does IEC 60335 differ from IEC 62368?
IEC 60335 covers household electrical appliances (heaters, kitchen gear, etc.), while IEC 62368-1 covers IT and audio/video equipment. Using the wrong one means the safety evaluation doesn't match the product's real hazards.
