# CB · CB certificate and report (IECEE scheme)

Test reports and certificates under the IECEE multilateral recognition scheme. A CB report is not itself a market-access mark, but it is the basis for conversion into many markets: member-country certification bodies accept it and issue national certificates once national differences are covered.

| | |
|---|---|
| Issued by | IECEE-recognised National Certification Bodies (NCBs) |
| Assessment route | Report recognition |
| How it is obtained | Test against IEC standards at a CB Testing Laboratory (CBTL). Folding the target markets' national differences into the same test round reduces later re-testing. |
| Marking rules | CB is a report and certificate, not a mark that can be applied to a product, and must not be presented as a market-access mark. |
| Validity and upkeep | Reports have no fixed expiry, but standard revisions or changes to cells or construction usually require additional testing or reissue. |
