Power Adapter Safety Certifications: UL, CE, UKCA, FCC and CB
A power adapter's safety marks decide whether it clears customs and an insurance audit. Know which standard covers fire and shock (UL/IEC 62368-1), which covers emissions (FCC, EMC), and which is just a material declaration (RoHS).
Safety: UL 62368-1 / IEC 62368-1
The current hazard-based standard for IT and AV power supplies. UL 62368-1 is the US mark; IEC 62368-1 is the international base. A CB certificate against IEC 62368-1 speeds national approvals. Older adapters may still show UL 60950-1, but new designs should be 62368-1.
Class 2: UL 1310
Limits output to 100VA and constrained current/voltage. Common for low-power adapters and it simplifies downstream wiring rules.
CE (Europe): LVD + EMC
CE is self-declared against two directives: LVD 2014/35/EU (electrical safety) and EMC 2014/30/EU (emissions and immunity). Both apply to adapters sold in the EU.
UKCA (United Kingdom)
The post-Brexit UK mark, technically aligned with CE. Required for Great Britain; keep a UKCA declaration on file.
FCC Part 15B (Emissions)
Sets conducted and radiated emission limits so the adapter does not interfere with radio. Required for the US market alongside UL.
RoHS
Restricts lead, cadmium and similar substances in the adapter's materials. It is a material declaration, not a safety test.
FAQ
Is CE a test mark?
No. CE is the manufacturer's declaration of conformity to LVD and EMC; the underlying tests are done to EN/IEC standards, often via a notified body.
Do I need both UL and CE?
Yes if you sell in both the US and EU. UL covers the US; CE covers the EU. A CB report against IEC 62368-1 is the common starting point for both.
