37+ Flash And Fire Point Apparatus Background. Hence, the fire is mostly not sustained. This apparatus is used for determination of flash point and fire point of petroleum products except fuel oil with open cup flash below 80°c as per specification ip 36 and is:

The apparatus consists of brass test cup with handle removable cup cover with. At flash point, more vapor may not be produced rapidly enough to sustain combustion. The flash point is the minimum temperature at which vapors given off by a liquid pool form an ignitable mixture with air.

The flash and fire point are the most important combustible properties used to determine the potential for the fire and explosion hazards of flammable material.

Flash & fire point apparatus used for determining the flash point of fuel oils and lubricating oil, bitumen other than cutback bitumen and suspension of solids in liquids, having a flash point above 49°c. The bitumen specimen should be heated above. Neither the flash point nor the fire point is related to the temperature of the ignition source or of the burning liquid, which are much higher. The flash point of a volatile material is the lowest temperature at which its vapours ignite if given an ignition source.
