Method Details	Observations	Remarks if, any
Guideline	OECD 103		the test item does not show strings of bubbles upto 300 deg C, thus boiling point was infered to be greater than 300 deg C
Method	Method according to Siwoloboff
Principle of Boiling point test	A sample is heated gradually in a tube which is immersed in a liquid bath.The sample tube is held in close contact with a thermometer and it contains a boiling capillary which is fused about1 cm above its lower end. Upon approach of the boiling temperature bubbles emerge rapidly from the lower open end of the capillary. The boiling temperature is that temperature at which, on momentary cooling, the string of bubbles stops and liquid suddenly rises in the capillary.
