CB Certification is widely known as the “Golden Key” to global markets for electrical and electronic products.It is a mutual recognition system established by IECEE (IEC System of Conformity Testing and Certification of Electrical Equipment), with the core value: One Test, Accepted Globally.

For manufacturers of batteries, power supplies, IT devices, home appliances and more, CB Certification brings clear benefits:

• Cost reduction: Avoid repeated testing across countries; save 30%–50% of certification costs
• Time saving: Shorten market entry time by 3–6 months
• Simplified process: Convert one CB test report & certificate into national certifications in 50+ member countries
• Enhanced credibility: Based on internationally recognized IEC standards

The full value of CB Certification depends on choosing a professional, reliable certification body.This article explains the complete CB process and recommends a trusted provider.

How to Get CB Certification? Full Process

Stage 1: Document Pre-review & Standard Matching

Prepare core documents:

• Product specification, schematic, PCB layout
• BOM & safety certificates for key components
• Structure drawing, explosion diagram, label drawing
• Multilingual user manual with warnings

A professional lab will:

• Match the latest IEC standards (e.g., IEC 62133 for batteries, IEC 62368-1 for IT)
• Identify design risks early to avoid delays

Stage 2: Sample Testing at Qualified CBTL

Samples are tested at an IECEE-recognized CBTL (CB Testing Laboratory).Typical test items:

• Batteries: overcharge, over-discharge, short circuit, vibration, shock, crush, temperature cycling, thermal abuse
• IT/AV equipment: withstand voltage, leakage current, grounding continuity, temperature rise, flammability

Stage 3: Report & Certificate Issuance

The lab issues a CB Test Report (TR), which is reviewed by an NCB (National Certification Body).Once approved, the CB Certificate is issued.

Stage 4: Global Conversion & Market Access

With the CB certificate and report, you can apply for national certifications with minimal country-difference testing:EU CE, US UL, Korea KC, Japan PSE, Saudi SASO, Australia RCM, etc.
