（AIT 551）AUTOIGNITION TEMPERATURE OF LIQUID

Autoignition temperature is the lowest temperature at atmospheric pressure at which a substance will burst into flame in the absence of an external source of ignition (spark or flame). The AIT (Auto-Ignition Temperature Tester) is used for the determination of the auto-ignition temperature of both liquid and solid chemicals through means of visual observation and sample temperature measurement.

APPLICATION

The measurement of the autoignition temperature of substances is essential for industry and technologies employing any high temperature operations. Liquid materials after exposure to temperatures may cause flammable vapors which in turn may lead to an explosion. The AIT is ideal for emerging technologies, operational safety control, research and development among many other applications. The results obtained are used for the classification of temperature class.
