90 individual test reports covering every thickness and build-up we produce — issued by WITC (Wuhan Inspection & Testing Certification Development Group), a CMA-accredited laboratory, under China's national safety-glass standard GB 15763.2-2005.
Why This Matters for Overseas Buyers
Samples were collected by the Wuhan Municipal Market Supervision Administration under random surveillance — we did not pick what went to the lab.
WITC holds China Metrology Accreditation (CMA No. 251700340165), the same framework ILAC/MRA signatory labs operate under.
Each report covers impact resistance, fragmentation, shot-bag impact, surface stress and thermal shock — the full GB 15763.2 battery with specific numeric results.
