RadEX · Independent Testing

The only comparative fire-suppression test a manufacturer has published in full — by an independent state laboratory, against a product taken at random from the market.

On 26 March 2025, the Research & Development Services of the Emergency Services Academy Finland (Pelastusopisto, Kuopio) tested the RadEX condensed-aerosol generator and issued official report No. 2025-133. The complete protocol is published below.

Two facts make the document unusual. First, it is an independent test by an accredited state institution, carried out with calibrated, certified instrumentation — a Testo 340 flue-gas analyser, a Dräger X-am 5000 multi-gas meter and a Graphtec GL840 data logger — with the gravimetric aerosol analysis performed by the Finnish Institute of Occupational Health. Second, the benchmark was not a laboratory sample but a commercial product purchased at random from the market — itself certified to UL, EPA SNAP and EN 15276-1 — and the entire comparative protocol has been released in full. We are aware of no other case in which a manufacturer has openly published a third-party comparative test of this kind.

Carbon monoxide, nitric oxide, oxygen and aerosol mass were measured after discharge, with and without fire, in a sealed chamber. Both systems extinguished the test fire within two to three seconds — RadEX using roughly a tenth of the active agent. On the measured emissions, the two differed by an order of magnitude.

Reference thresholds (NIOSH IDLH): 1200 ppm for carbon monoxide, 100 ppm for nitric oxide; the occupational oxygen limit is 18 %. In this test the certified product’s carbon-monoxide peak reached about 6.7× the IDLH and its nitric-oxide peak about 9.6×; RadEX remained below the carbon-monoxide threshold and at roughly 1.4–1.8× the nitric-oxide threshold.

An independent laboratory, a comparator bought at random, and the entire protocol open to inspection — the result is documented, not asserted.
