✦ Synopsis

A procedure for measuring the fuming propensity of bituminous materials has been developed. This is based on the response of a flame-ionization detector to hydrocarbon vapours emanating from a large-size sample heated at a controlled rate of temperature rise and swept with a slow, constant flow rate of an inert gas. The fuming propensity is related to the temperature of equal volatility, defined by the measured temperature recorded for a specific, arbitrarily chosen, peak height produced on the flame-ionizationdetector chart. The quantity of fumes generated from heated bituminous material is inversely related to the temperature of equal volatility.
