When the flame point is determined, the water content of the sample
must be considered. Flame points above10c, the boiling point of water,
TT" could not beawtortsat," As could be expected none of the tested samples
did have a flame point below100C. It should be obvious that none of the
products would contain flammable sblvents.
.
The surface, or interphase tensions can be seen from Table 2. The
surface tension water/air generally drops some for `concentrations from 50 mg/l .-
0300 mg/L. The surface tension is leastaffectedfor Ko$ (Protein-foas i
extinguisher), most effected for two Light-Uster types of FC 206-type.
The reason for this 1s found in the cheaicsl composition of the extiguishing
compounds. Protein foam agents can be expected to be generally isactiv to
the vater/air interphase; while tensides and also so called "synthotic'pro-
ducts are fnterphase active. The interphase activity is less a product specific, but rather a group specific characteristic.

results, depending upon what importance is given to the different criteria.
