Bitumen Flash and Fire Point Test
At high temperatures depending upon the Grades of Bitumen materials leave out volatiles. And these volatiles catch fire which is very hazardous and therefore it is essential to qualify this temperature for each bitumen grade. BIS defined the ash point as the temperature at which the vapour of bitumen momentarily catches fire in the form of ash under specified test conditions. The Fire Point is defined as the lowest temperature under specified test conditions at which the Bituminous material gets ignited and burns.
