More than a test report
A certification lab tells you the result. We also tell you why, and help you control the risk.
Large-scale tests plus simulation
A 20 MW indoor fire hall, an outdoor large-scale fire site in Hebei and an explosion test site in Nantong — backed by simulation to predict outcomes before a test and explain them after.
Help when a test fails
Our engineers take part in test planning and failure analysis and propose design changes — not just a "fail" on a report.
Data certification bodies accept
CNAS L9503 under ILAC mutual recognition. Witness lab for TÜV Rheinland, Intertek and CSA. North American P.E. stamping through Summit and Jensen Hughes.
Industries
Energy storage and data centres are the two fastest-growing fields — and both come down to the fire performance of enclosures and building envelopes.
Battery energy storage
From cell to 40 ft container: UL 9540A and UL 9540B testing, large-scale fire and deflagration tests, enclosure fire resistance, simulation and NFPA 855 compliance support for BESS manufacturers and integrators.
