Ignition temperature > 400°C

Isothermal tests were performed

Layer thickness: 5 mm

Conclusions:
No ignition has occurred.
Layer ignition temperature (LIT) of T003063 is > 400°C.
Endpoint:
relative self-ignition temperature (solids)
Type of information:

Qualifier:
equivalent or similar to
Guideline:
EU Method A.16 (Relative Self-Ignition Temperature for Solids)
Deviations:
yes
Principles of method if other than guideline:
A heating rate of 0.6°C/min is used instead of 0.5°C/min due to an alternative Swiss Chemical Industry method and technical restriction of the apparatus used. Cylindric wire baskets with 0.2 mm openings are used.
GLP compliance:
no
Remarks on result:
no self ignition observed under the test conditions
Remarks:
End temperature oven = 350°C.

Heating rate: 0.6 °C/min, end temperature oven 350 °C.

The sample is heated from room temperature (about 20 °C) to ± 350°C.

Melting endotherm at 109°C.

The sample shows no self-heating in the test run.

Conclusions:
The substance T003063 is not auto-flammable up to the temperature applied in the test.
The substance T003063 has no relative self-ignition temperature.

Description of key information

The relative self-ignition temperature does not need to be determined because the substance has a melting point below 160°C (see REACH Annex VII).

Key value for chemical safety assessment

Additional information

Only supporting information (Klimisch 4, Product Safety Center of Janssen Pharmaceutica N.V.) is available on autoflammability. In a dust layer test (isothermal test runs), no ignition occurred up to the highest applied temperature (i.e. 400°C). In a BAM oven test, the minimum ignition temperature was determined to be 460°C. Finally, in a Grewer oven test with end temperature 350°C, no self-ignition of the test item was observed, i.e. the substance does not have a relative self-ignition temperature. Clearly, the substance does not need to be considered as autoflammable. Any new tests can be waived (see REACH Annex VII) because the melting point of the test item is < 160°C.
