Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
