Test methods for assessing the hazard of spontaneous ignition in oil-soaked lagging on hot pipes have been investigated. One, based on the determination of the critical temperature for ignition of cube shaped samples of lagging, is suitable for screening purposes and permits a rough estimate of conditions for ignition on a pipe. The other, based on an electrically heated pipe devised for the purpose, yields more directly applicable results but is less suitable for use when a large number of tests have to be performed.
