An independent laboratory measured the Minimum Explosible Concentration (MEC) for Aerogel dust to be 575 g/m3 per ASTM E1515-03, "Standard Test Method for Minimum Explosible Concentration of Combustible Dusts”. The laboratory also performed a Minimum Ignition Energy (MIE) test on the dust per ASTM E2019-03, “Standard Test Method for Minimum Ignition Energy of a Dust Cloud in Air”. No ignition was observed at 28.8 Joules Capacitor Stored Energy, the maximum capacitor stored energy delivered by Electrostatic Discharge Tester used for the test.
