Summary

Spreading coefficient of AFFF solution FC-194 (15.5 dynes/cm) on seven hydrocarbon liquids at 25 °C; negative values gave no film. Based on Scheffey (2002), pp. 4-93 to 4-94.

Original vector illustration for Aqueous film-forming foam, level 2 Intermediate.

Source basis: Scheffey (2002), p. 4-93 (Table 4-4.1, Equation 9) and p. 4-94 (Table 4-4.2)
Alt text: Bar chart of spreading coefficients of one AFFF solution on seven fuels, from −1.2 for n-heptane to +5.2 for JP-5.
