When used in aerial shells, the stars may sometimes be required to be " primed " with an ignition coating, consisting of a pyrotechnic mixture with an ignition temperature lower than that of the star.

In this connection number of tsts are to be carried out for finding the parameters like Flash point, composition by using chromotography, auto ignition temperature, purity of sulphur, Lower and upper explosive limits of products etc.

If the fluid in a hose actually was hotter than the hose's ignition temperature, then it would heat the whole hose by conduction, and the outside would ignite .-- Anonymous, 04 : 06 UTC, January 2, 2008.
24.
The normal solution to the problem of heat is to increase the heat resistance by switching to a propellant with a higher ignition temperature, typically a non-crystalline explosive carefully formulated to provide an appropriate rate of combustion.
25.
FAA Administrator Jane Garvey called for a study to explore the viability of converting production Jet A fuel, the fuel currently used by commercial aircraft operators, to JP-5, a more expensive fuel with a significantly higher ignition temperature.
26.
As per SANS 11014 : 2010 this should address : appearance of the chemical ( e . g . physical state, form, and colour ), n-octanol / water partition coefficient, auto-ignition temperature, decomposition temperature, and / or viscosity.
27.
But in the 1980s, researchers at the laboratory began developing a computer program that would model the behavior of fire in an enclosed space, using data on the type, amount and ignition temperatures of whatever flammable materials were present.
28.
That we can speak of an ignition temperature needed to initiate burning or an explosion demonstrates that there is an irreversible route to increase the combined Entropy of the system and its environment; it just isn't happening right now.
29.
The start of vaporisation causes a delay before ignition and the characteristic diesel knocking sound as the vapour reaches ignition temperature and causes an abrupt increase in pressure above the piston ( not shown on the P-V indicator diagram ).
30.
The cook-off problem was reduced, by using a denatured HMX propellant with a special binder and coating for the ammunition that increased the spontaneous ignition temperature by another 100 �C above that of standard, nitrocellulose ( 180 �C ) propellant.
