Endpoint:
relative self-ignition temperature (solids)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
14 September 2009 - 16 November 2009
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
EU Method A.16 (Relative Self-Ignition Temperature for Solids)
Version / remarks:
Publication No. L383, December 1992
Deviations:
no
GLP compliance:
yes (incl. certificate)
Other quality assurance:
other: Chemikaliengesetz ('Chemicals Act') der Bundesrepublik Deutschland (ChemG), Anhang 1 ('Annex 1'), 2008 and Directive 2004/10/EC of 11 February 2004 (Official Journal No. L 50/44)
Key result
Relative self-ignition temperature:
>= 400 °C
Remarks on result:
no self ignition observed under the test conditions

The test item showed no self-ignition reaction when heated on average at 0.5 °C/min up to 400 °C. At the end of the experiment the test item was a liquid.

Conclusions:
The test item did not self-ignite at when heated up to 400 °C, therefore, the test item self-ignition temperature was determined to be > 400 °C.
Executive summary:

Self-ignition of the test item was investigated in a EC A.16 method guideline study. The test item was added to a 2 x 2 x 2 cm steel cube with 0.045 mm holes until it was filled. The test item was then put in the centre of an oven at room temperature, and the oven heated at on average 0.5 °C/min up to 400 °C. To measure self-ignition, if an exothermic reaction occurs, the temperature of the oven at which the sample reaches 400 °C by self-heating was appointed as the self-ignition temperature. The test item did not self-ignite at temperatures up to 400 °C, therefore the self-ignition temperature was determined to be > 400 °C.

The study is a GLP compliant guideline experimental study, fully adequate for assessment of this endpoint.

Study period:
20 June 2017 - 22 June 2017
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
EU Method A.16 (Relative Self-Ignition Temperature for Solids)
Deviations:
no
GLP compliance:
yes (incl. certificate)
Key result
Relative self-ignition temperature:
>= 400 °C
Remarks on result:
no self ignition observed under the test conditions
Conclusions:
The test item was found to not self-ignite below 400 °C.
Executive summary:

The self-ignition temperature of the test item was determined in a study conducted in accordance with EC Method A.16 and it was found to not self-ignite below 400 °C.

The study is a guideline GLP experimental study, and is deemed reliable without restrictions.

Description of key information

The self-ignition of the test item was investigated in two studies; in both studies the test item did not self-ignite at temperatures up to 400 °C. Therefore, the self-ignition temperature of the test item is determined to be > 400 °C.

Key value for chemical safety assessment

Additional information

The self-ignition of the test item was investigated in two GLP compliant EC A.16 method guideline studies (Fieseler 2009c, Cage 2018b).

Both studies follow standard guidelines and are GLP-compliant, and are deemed reliable without restrictions.
