KN-659 Autoignition Temperature Tester

Overview

KN-659 Autoignition Temperature Tester conforms to ASTM E659 Standard Test Method for Autoignition Temperature of Chemicals. A small, metered sample of the product to be tested is inserted into a uniformly heated 500ml glass flask containing air at a predetermined temperature. The contents of the flask are observe in a dark room for 10min following insertion of the sample, or until autoignition occurs. Autoignition is evidenced 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 hot-flame ignition occurs for a series of prescribed sample volumes is taken to be the hot-flame autoignition temperature of the chemical in air at atmospheric pressure. Ignition delay times (ignition time lags) are measured in order to determine the ignition delay-ignition temperature relationship.
