EPA evaluated three laboratory methods: the Revised Standard Dispersant Effectiveness Test currently used (and currently required by regulation) in the United States, the Swirling Flask Test (developed by Environment Canada), and the IFP-Dilution Test (used in France and other European countries). Six test oils and three dispersants were evaluated; dispersants were applied to the oil at an average 1:10 ratio (dispersant to oil) for each of the three laboratory methods. A screening criterion was established that required a combination that gave at least 20 percent effectiveness results. The selected combination turned out to be Prudhoe Bay crude oil (an EPA-American Petroleum Institute Standard Reference Oil) and the dispersant Corexit 9527. EPA's evaluation concluded that the three tests give similar precision results, but that the Swirling Flask Test was fastest, cheapest, simplest, and required least operator skill.
