The laboratory holds both CMA (China Inspection Body and Laboratory Mandatory Approval) and CNAS (laboratory accreditation). Reports are accepted across China and in overseas markets.
CMA
- What it is: granted by the Chinese metrology accreditation authority; it gives inspection and testing reports legal effect.
- Where it applies: product acceptance within China, quality dispute resolution, regulatory enforcement.
- Why it matters: the report can be used directly in legal and commercial settings without further proof.
CNAS accreditation
- What it is: laboratory competence accreditation carried out by CNAS to ISO/IEC 17025.
- Where it applies: internationally mutually recognized, widely accepted by overseas customers and markets.
- Why it matters: CNAS reports are the norm for EU and global export projects.
CBTL capability
- In-house CBTL laboratory able to issue CB reports.
- A CB report is the common document for international electrotechnical certification — one test converts to national certificates in many markets.
- Formal certification is carried out by bodies authorized to issue it; the laboratory provides the supporting test data.
Service notes
The laboratory holds both CMA and CNAS accreditations, with approximately 10,000 m² of space and 500+ instruments. All testing is completed in our own laboratories — no subcontracting. On-site visits and witnessed testing are supported.
Testing is scheduled per project. When submitting samples, tell us your expected timeline; we will confirm a feasible plan against current availability and keep you updated at each milestone.
Matching accreditation to the report's purpose
Whether a report can be used depends on the accreditation of the issuing body and the destination of the project: domestic market surveillance, tenders and customer factory audits look for the CMA mark; overseas customers and multinational supply chains look for the CNAS mark and international mutual recognition; multi-country conversion for electrotechnical products looks for a CB report issued by a CBTL. One project can serve several purposes at once — state the report's intended use before submission and the engineers will confirm the coverage.
How to verify a test report
- The report number is unique and can be checked back with the issuing body.
- The CMA / CNAS marks and the accreditation schedule are present, and the schedule lists the accredited scope cited in the project.
- The test conditions, the standard revision and the commissioning party match, and the signatures, stamps and page count are complete.
The boundary of the accredited scope
The specific items covered are defined by the annex to the current accreditation certificate, which this page does not enumerate. The direct way to confirm whether an item can carry a CNAS mark is to send the standard number and conditions to an engineer before shipping samples; the answer is confirmed in writing at the planning stage, so a mismatch is never discovered after the report is issued.
Capability beyond accreditation
Beyond accreditation, whether a report supports a customer decision also depends on engineering interpretation: a corrective direction when data exceeds a limit, root-cause analysis for a failed sample, and the documentation route for a certification project. The laboratory also runs failure analysis and global certification support, so questions that go beyond the report are answered by the same team.
