- Executive summary:
The test covered the determination of hot and cool flame autoignition temperatures of the liquid chemical in air at atmospheric pressure in a uniformly heated vessel. A small, metered sample of the product to be tested was inserted into a uniformly heated 500 ml glass flask containing air at a predetermined temperature. The contents of the flask were observed in a dark environment for 10 minutes following insertion of the sample, or until autoignition occurs. Autoignition was identified by the sudden appearance of a flame inside the flask and by a sharp rise in the temperature of the gas mixture. The lowest internal flask temperature at which the hot-flame ignition occurred for a series of prescribed sample volumes was taken to be the hot-flame autoignition (AIT) of the chemical in air at atmospheric pressure. Ignition delay times (ignition time lags) were measured in order to determine the ignition delay / ignition temperature relationship. The lowest temperature at which cool flames (CFT) were observed was also recorded. Any small rises in temperature (exotherm) of the gas mixture are noted and the lowest temperature (RTT) recorded. In all instances the ignition delay times are recorded.
No cool flames were observed. Ignition produced a medium to large flame.
