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 in include chemical and physical property specifications, foam quality (expansion and drain time), film formation, and sealability tests. The MIL-SPEC test protocol also includes extensive environmental impact based on biodegradability studies like Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and aquatic toxicity.
