If 100g of material is burned and the material is diluted in the air of chamber, concentration of each generated gas is given by the following equation. C × 100 ×V C8 = --------------- (ppm) m C = concentration of gas in test chamber (ppm) m = fire test mass (g) V = volume of test chamber (m3) Toxicity Index C81 C82 C83 C8n Toxicity Index = Σ ------ + ------ + ------ + … + ------ Cf1 Cf2 Cf3 Cfn 1, 2, 3, ... indicates each found Gas. Cf = concentration of the gas considered fatal to man for a 30 minute exposure time(ppm)
