Reference 4

Endpoint:

relative self-ignition temperature (solids)

Type of information:

experimental study

Adequacy of study:

supporting study

Study period:

2008

Reliability:

4 (not assignable)

Rationale for reliability incl. deficiencies:

documentation insufficient for assessment

Qualifier:

equivalent or similar to guideline

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).

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.
