PHOS-CHEK 6% AFFF MIL-SPEC

PHOS-CHEK^® 6% AFFF MIL-SPEC foam concentrate is a C6-based product on the Department of Defense Qualified Product Database (QPD) – Qualified Products List (QPL). The most common use for 6% AFFF MIL-SPEC foam is by the US Navy.

The MIL-SPEC testing protocol (DOD MIL-PRF-24385) is the most rigorous test program for foam concentrates. The foams must pass multiple fire tests and confirm performance when diluted with both fresh and seawater. Fire performance is confirmed in both 2.6m2 and 4.6m2 unleaded gasoline pool fires at half strength and five times concentration. Other requirements include chemical and physical property specifications, foam quality (expansion and drain time), film formation, and sealibility tests. The MIL-SPEC test protocol also requires a determination of environmental impact based on biodegradability studies like Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and aquatic toxicity.
