As could be expected none of the tested samples did have a flame point below 100 C. It should be obvious that none of the prodects would contain flammable solvents. 3) The surface, or interphase tensions can be seen from Table 2. `The surface tension vatar/air generally drops some for concentrations from 50 mg/l |: to 300 mg/l. THe surface tension ds lesst effected for Bo$ (Protein-foss i extinguisher), most effected for two Light-Water types of FC 206- type. The reason for this is found in the chemical composition of the extiguishing compounds. Protein foam agents can be expected to be generally isactiv to the water/air interphase; while tensides and also so called "synthetic"products are interphase active. The interphase activity is less a product specific, but rather a group specific characteristic. Table 2 Intecohure notivity . To.
