CB Product Safety Certification: Complete 2025 Guide

2025-10-31

The CB Scheme, managed by the IECEE, operates on the principle of “Test Once, Use Everywhere.”
While it doesn’t directly grant market access, it significantly reduces retesting costs and time-to-market for global manufacturers seeking multiple country approvals.



1️⃣ CB Certification Process Overview

Step 1: Preparation & Application

· Identify Standards:
Determine the applicable IEC safety standards for your product type (e.g., IEC 62368-1 for IT/AV equipment, IEC 60335-1 for household appliances).

· Select a National Certification Body (NCB):
Choose an IECEE-recognized NCB (e.g., CQC, TÜV Rheinland, SGS). The applicant must be a registered legal entity.

· Check National Differences:
Identify country-specific deviations (such as China’s GB standards) early to minimize conversion time later.

· Prepare Documentation:
Include English manuals, circuit schematics, PCB layouts, and critical component lists (preferably with CB certificates for those components).


Step 2: Sample Testing (2–4 Weeks)

Send product samples to a CB Testing Laboratory (CBTL) for evaluation. Testing varies by product category:

· IT Equipment: Electrical insulation, shock protection, temperature rise, abnormal operation.
· Household Appliances: Leakage current, mechanical strength, IP rating, heating element protection.
· Battery-Powered Products: Provide IEC 62133 test reports; includes overcharge/discharge and short-circuit tests.

Failed tests require corrective actions and retesting, typically adding 1–3 weeks to the process.


Step 3: Review & Certification

· The NCB reviews all test results and issues both the CB Certificate and CB Test Report.
· Typical total timeline: 4–8 weeks.
· CB Certificates have no fixed validity, but remain valid only if the design, components, and standards stay unchanged.

3️⃣ Critical Considerations for 2025

1️⃣ Certificate Types:
For components (CCP) or specific characteristics (ACP), a CB Certificate may not apply — instead, a CCP or ACP certificate will be issued. Always confirm with your NCB.

2️⃣ Sample Consistency:
Test samples must match mass-production units. Any changes to critical components (e.g., batteries, IC chips) require NCB notification and possible retesting.

3️⃣ Standard Updates:
When an IEC standard is revised, a 1–2 year transition period is provided. To maintain CB validity, update your test reports accordingly.

4️⃣ Strategic Use of CB Reports:
Even in non-IECEE countries, CB Certificates and Test Reports are often accepted as proof of international compliance, helping shorten local approval cycles.



4️⃣ Key Takeaways

✅ The CB Scheme streamlines multi-market certification by harmonizing IEC standards.
✅ Preparation and understanding of national differences saves time and cost.
✅ Regularly update CB documentation to remain compliant with the latest IEC standards.
✅ Partner with experienced certification consultants like BLUEASIA for efficiency and accuracy.



5️⃣ Frequently Asked Questions (FAQ)

Q1: How long does CB certification take?
A: Typically 4–8 weeks, depending on test complexity and corrective actions required.

Q2: Is the CB certificate valid worldwide?
A: While not a market access license, it’s recognized across 50+ IECEE member countries, easing national approval processes.

Q3: When should companies update CB reports?
A: Whenever there’s a product design change or IEC standard revision affecting key safety requirements.

Q4: Can CB reports be reused for CCC or other national certifications?
A: Yes — many certification systems (like CCC, PSE, KC, and SIRIM) accept CB test data as part of their local approval process.

Q5: What’s the advantage of working with a certification consultant?
A: Consultants like BLUEASIA help you align CB, CCC, and other local standards, saving time, avoiding retests, and ensuring compliance documentation meets IECEE requirements.
