Method details		Observations	Remarks if, any
Guideline	OECD 103	-
Method	Method according to Siwoloboff	-
Principle of method	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.	-

Decomposition	If oil bath is used, specify   ·        Liquid paraffin ·        Silicone oil	SILICON
Atmospheric pressure	hPa	968.0
Boiling point (°C) (RESULT)	Deg C	Greater than 240
