Hydrogen has an autoignition temperature of 858K requiring an ignition source to combust in an IC engine (Lambe, Watson 1993).
Topics include a standard practice for conducting ruggedness tests, the minimum autoignition temperature of dust clouds, separating liquid residue from fire debris samples, preparing items involved in litigation, and handling unbound engineered nanoscale particles in occupational settings.
Autoignition temperature (430[degrees]C) is lower than the melting temperature (650[degrees]C), so any spark can cause the ignition of chips or dust.
A series of tests are conducted until a minimum autoignition temperature (MAIT) is determined to a specified accuracy (typically |+ or -~ 10 |degrees~ C).
