CB Certification: A Shortcut to Multiple Certifications from a Single Test
The application process for CB certification (under the IECEE system) for electrical equipment involves: confirming the applicable IEC standard, selecting a CB laboratory, submitting samples for testing, obtaining the CB Test Certificate and report, and subsequently converting these into certifications for various countries. Industry experts note that the core value of CB certification lies in the “one test, multiple certifications” approach: CB Test Certificates are mutually recognized by IECEE member countries.
A single report can be used to obtain certifications such as CE (EU) and SAA (Australia), thereby eliminating the need for repetitive testing and serving as a time- and cost-efficient pathway for exporting to multiple markets.
Five Steps to Application
- Step 1: Confirm Standards – Identify the applicable IEC standard for the product (e.g., IEC 61439 or IEC 62271);
CB certification is based on IEC standards. - Step 2: Select a Laboratory – Choose an IECEE-recognized CB laboratory (NCB/CBTL, such as TÜV, SGS, or CQC); the CB report must be issued by an accredited body.
- Step 3: Submit Samples for Testing – Provide samples and technical documentation; testing (covering safety and performance) is conducted according to IEC standards, resulting in the issuance of a CB Test Report.
- Step 4: Obtain the Certificate – The NCB reviews the results and issues the CB Test Certificate, which is valid for several years (typically 3 years).
- Step 5: Convert to Other Certifications – Use the CB certificate and report to apply for certification in target markets (e.g., EU CE, Australian SAA, or various Southeast Asian countries), avoiding the need for repeat testing.
Key Application Points
First, choose the right NCB. CB certificates are issued by national NCBs, and acceptance levels for certificate conversion vary;
select an NCB that is highly recognized in your target markets. Second, ensure standard alignment.
CB certification is based on IEC standards, so the product must comply with the relevant IEC standard.
Third, ensure documentation is complete.
Ensure all drawings, component certificates, and technical documents are prepared upfront.
Regarding timelines and costs: the CB certification process takes approximately 1 to 3 months, and the cost is lower than conducting separate tests for each individual country.
Pitfalls to Avoid
First, “non-accredited bodies”: organizations not accredited by the IECEE cannot issue valid CB certificates.
Second, “non-compliant standards”: using the wrong IEC standard for CB testing leads to the rejection of certificate transfers.
Third, “incomplete reports”: missing information in test reports hinders the transfer process.
Trends and Recommendations
The IECEE system is expanding mutual recognition, with a growing number of countries and product categories included in the CB transfer scheme.
Exporters are advised to select accredited National Certification Bodies (NCBs), ensure standards align correctly, and adopt a “one test, multiple certificates” approach.
The CB scheme offers a streamlined path to exporting to multiple countries—allowing a single test report to facilitate market access across various regions.
