Principle of Boiling point test

The boiling point of a liquid is the temperature at which that liquid is converted to a gaseous state. It can be defined as the temperature at which the vapour pressure of the liquid becomes equal to the pressure at the surface of the liquid.

 The test item liquifies at 222 °C, but oozes out of capillary in form of blisters.Thus, no string of bubbles were observed upto 300 °C inferring boiling point to be greater than 300°C.

Conclusions:
The boiling point determination of Test item was done as per the test guideline OECD 103. The method followed was according to Siwoloboff. the test item liquifies at 222 °C, but oozes out of capillary in form of blisters.Thus, no string of bubbles were observed up to 300 °C inferring boiling point to be greater than 300°C. at 983.3 hPa.
Executive summary:

The boiling point determination of Test item was done as per the test guideline OECD 103. The method followed was according to Siwoloboff. the test item liquifies at 222 °C, but oozes out of capillary in form of blisters.Thus, no string of bubbles were observed up to 300 °C inferring boiling point to be greater than 300°C. at 983.3 hPa.

Description of key information
