Reference

Endpoint:

relative self-ignition temperature (solids)

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.16 (Relative Self-Ignition Temperature for Solids)

Deviations:

no

Principles of method if other than guideline:

The substance under test was placed in a wire basket with 8 ml volume in an oven at room temperature. The oven was heated up with a rate of 0.5 K/min up to 400 °C. The temperature of the center of the sample and the temperature of an inert reference sample, which was placed in the oven too, were recorded. For the purpose of this test, the temperature of the oven at which the sample temperature reached 400 °C by self-heating is called the selfignition temperature.

GLP compliance:

yes

Specific details on test material used for the study:

Storage: Room temperature
Expiration date: 2017-10-10

Remarks on result:

no self ignition observed under the test conditions

Remarks:

does not undergo spontaneous combustion

In the temperature/time diagram a very small endothermic effect in the range up to about 180 °C and a little exothermic effect in the temperature range of about 208 °C to about 285 °C oven temperature was observed. The maximum temperature of the sample in the range of exothermic reaction was 260 °C.

In the sense of the test procedure A.16 Bayscript Gelbkomponente is not liable to self-ignition. At the end of the test the basket was filled to about 80 % with a black clumpy powder.

Conclusions:

Bayscript Gelbkomponente is not liable to self-ignition and does not undergo spontaneous combustion according to test procedure A.16, at the end of the test the basket was filled to about 80 % with a black clumpy powder.

Executive summary:

The test was performed as stipulated in EC Test Procedure A.16 'Relative self-ignition temperature for solids'.
