The CB Scheme simplifies global market entry by reducing duplicate testing. Here’s a breakdown of required documentation and certificate validity based on the latest information.
| Document Category | Required Files | Key Points |
| Company Credentials | CB Application Form | Use IECEE or NCB-specific forms. Accurately complete company and product details. |
| Business Licens | For applicant and manufacturer (if different, include an authorization letter). Trademark Certificate/Authorization | Only one brand per application unit. |
| Technical Files | Product Manual Circuit Diagrams & PCB Layouts Product Structure & BOM Critical Component Proof | In English or target market language; include safety warnings and key specifications. Clearly identify critical components. llustrate safety design; list all components, highlighting critical safety items. CB Test Certificates or compliance evidence for fuses, power cords, etc. |
| Testing Support | Compliant Samples Product Consistency Declaration | Usually 1–3 units matching mass production models. Applicant declares that samples/technical files match mass-produced goods. |
CB Certificate Validity:
1.No Official Expiry: The IECEE doesn’t set a fixed validity period. However, certificates older than three years may face extra scrutiny or require additional data from NCBs.
2.Contingent on Stability: Validity depends on no changes to the product design, referenced standards, or critical components. Significant changes or standard updates necessitate re-evaluation.
Process & Recommendations:
1.Plan Ahead: Discuss target markets with your NCB to include national differences in testing, saving time later.
2.Maintain Consistency: Ensure technical files and test samples exactly match mass-produced goods.
3.Monitor Standards: Track IEC standard revisions. Transition periods (usually 1–2 years) require updating product compliance; otherwise, older CB Reports become obsolete.
