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)

Key result
Remarks on result:
no self-ignition observed up to the melting point

Three replicate tests were performed.

Conclusions:
No relative self-ignition of the test item could be observed until the decomposition point of 236.8 °C. Thus no self-ignition temperature could be stated.
Executive summary:

A study was performed according to Regulation (EC) No 440/2008, Method A.16 in order to determine the relative self-ignition temperature of the test item with the help of the automatic auto-ignition tester. A certain amount of the test item under the assay was placed in the oven at ambient temperature. The temperatures of the oven and the sample were continuously recorded. While the temperature of the oven was increased at a rate of approximately 0.6 °C/min, the temperature of the sample was increased by about 0.5 °C/min up to the decomposition temperature of 236.8 °C. It its expected that until the decomposition point no self-ignition of test item will be observed. Thus, for the test item no self-ignition temperature could be stated.

Description of key information

No relative self-ignition of the test item could be observed until the decomposition temperatrure of 236.8 °C. Thus no self-ignition temperature could be stated.

Key value for chemical safety assessment

Additional information

A study was performed according to Regulation (EC) No 440/2008, Method A.16 in order to determine the relative self-ignition temperature of the test item with the help of the automatic auto-ignition tester.

It its expected that until the decomposition point no self-ignition of test item will be observed. Thus, for the test item no self-ignition temperature could be stated. The study was initiated before 31 March 2018 but was not completed by the CRO in due time to complete the registration dossier. The study record will be updated as soon as the results will become available.
