Description of key information

Method A.16 Relative self-ignition temperature for solids, Council Regulation (EC) No.440/2008, published in O.J. L 142, 2008, was performed.
GLP study.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
270.2 °C

Additional information

The relative self-ignition temperature of test substance was measured.

Principle of test method:

A certain volume of the substance under test is placed in an oven at room temperature; the temperature/time curve relating to conditions in the centre of the sample is recorded while the temperature of the oven is

increased to 400°C or to the melting point if lower, at a rate of 0.5°C/min. For the purpose of this test, the temperature of the oven at which the sample temperature reaches by self-heating is called the self-ignition temperature.

Reaction product of Distillates (petroleum), acid-treated heavy naphthenic and calcium oxide showed relative self-ignition temperature 270.2°C.
