Refractometry and Extinguishment/Burnback Testing of Pacific Air Forces AFFF
Abstract
At the request of Pacific Air Forces (PACAF), the Air Force Research Laboratory (AFRL) performed refractometry and extinguishment/burnback tests on samples of Ansulite and 3M aqueous film forming foam (AFFF) from an overseas air base. The Fire Chief at the air base was concerned about the effectiveness of the agent because of refractometry tests conducted on the foam concentrate and foam dilutions. AFRL used an Atago, Palette Series PR-32a Digital Refractometer to perform refractometry testing on fives samples. Each agent was mixed twice and three test were conducted with each agent/water mixture. Testing showed that even high end, calibrated digital refractometers produce varied results. After the refractometry testing was completed, two agents were chosen to conduct the Military Specification extinguishment and burnback. Results showed that both AFFF samples exceeded MIL-SPEC minimum requirements for extinguishment and burnback indicating that they maintain their fire fighting effectiveness.
