What is a CB scheme report, and when is it enough?

Main answer · Wecent Editorial Team

Short answer: Not quite. A CB report and certificate, issued under the IECEE CB Scheme by a recognised certification body, show the charger was tested to an IEC safety standard, usually IEC 62368-1 for chargers. Other participating certification bodies can use it as the basis for national certifications, reducing retesting. But it isn’t itself a CE, UKCA, FCC or national mark, it may not include national deviations, and it doesn’t cover EMC, radio, energy-efficiency or chemical requirements.

What the CB scheme is

The IECEE CB Scheme is an international system in which national certification bodies accept each other’s test results to IEC standards. A CB test certificate (CBTC) with its test report says the product was tested and found to comply with a specific IEC standard and edition, including any national differences listed in the report.

What it helps with

• National certifications: bodies in many countries can issue their certificate based on the CB report, with limited additional tests.
• CE technical file: the safety part of a CE assessment usually uses EN 62368-1 test results; a CB report with EU group differences can support this.
• Buyer confidence: it shows independent safety testing by a recognised body.

What it doesn’t cover

• EMC (emissions and immunity), required for CE and FCC.
• Radio requirements for wireless chargers (RED, FCC).
• Energy efficiency (EU Ecodesign, US DoE).
• RoHS, REACH and other chemical rules.
• Country marks that require their own certificate, such as PSE in Japan or KC in Korea, which may need local procedures.

Check the report itself

1. Model numbers listed match your charger, including the branded model name if applicable.
2. Standard edition is current.
3. National differences cover your target markets.
4. Ratings and plug types match your version.
5. The certificate can be verified with the issuing body or the IECEE database.

Brand name and model changes

If you sell under your brand with a different model number, the report usually needs to list it, or you need a documented link between your model and the factory’s. Ask Wecent whether a listing of your model can be added.

When is it enough?

For electrical safety evidence in a technical file or for a buyer’s request, a current CB report covering your model is often what’s needed. For market access, it is a supporting document, not the whole answer.

Where this answer says confirm with Wecent, the detail is not published on the product page and has to come from the datasheet or the factory. General facts come from the standards bodies, regulators or device makers named in the text.
