- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2018-03-08
- 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
- GLP compliance:
- yes (incl. QA statement)
- Key result
- Remarks on result:
- no self-ignition observed up to the melting point
- Conclusions:
- The test item was determined to be not self-igniting up to the melting range of 173 - 177 °C under the test conditions.
- Executive summary:
A study was conducted according to Commission Regulation (EC) No. 440/2008 method A.16 in order to determine the self-ignition temperature of the test item by using the oven ZPA3. The test item was filled into a cube and placed into the temperature-programmed laboratory oven (ZPA3, Petrotest). The oven was heated from 21.1 °C to 182 °C. The final oven temperature was chosen under consideration of the melting range of 173 - 177 °C. While heating of the oven with a heating rate of 0.57 K/min the temperatures of the test item and the oven were printed every 5 minutes. No increase of the test item temperature in comparision to that of the oven was detected and no signs of self-ignition could be observed. Hence, the test item was considered to be not self-igniting up to the melting range of 173 - 177 °C under the test conditions.

Temperature Data
The temperatures which were measured in the experiment are presented in the following table.As many values were recorded, only the values every 60 minutes (until the oven had reached the chosen temperature) are presented.

Determination of heating rate
The heating rate was calculated using the following equation:
Heating rate = (T2 -T1) / (t2 -t1)
T1 = Temperature after 5 minutes in °C
T2 = End temperature in °C
t1 = 5 min
t2 = time at which the end temperature was reached in min.

No increase in the temperature of the sample in comparison to that of the oven could be detected; also no signs of ignition could be observed. The test item is considered as showing no self-ignition up to the melting range of 173 – 177 °C under the test conditions. No observations were made which might cause doubts concerning the validity of the study outcome.
