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)
Version / remarks:
(2008)
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Specific details on test material used for the study:
Identification FAT 40854/A TE
Description Reddish-brown powder (determined at NOTOX)
Batch TZ 5719 / BOP 02-11
Content 46.2 % (4 main constituents)
Test substance storage: At room temperature in the dark
Stability under storage conditions: Stable
Expiry date: 01 April 2016
Relative self-ignition temperature:
314 °C
Remarks on result:
other: strong exothermic effect

The temperature of the test substance reached 400 °C at an oven temperature of 314 °C. After the experiment, the test substance had turned into a charred residue.

Conclusions:
FAT 40854/A is self-ignitable at 314 °C under the conditions of EU Method A.16.
Executive summary:

In a GLP-compliant study, the self-ignition temperature of FAT 40854/A was determined according to EU method A.16 using a temperature programmed laboratory oven, a stainless steel wire mesh cube, NiCr/NiAl thermocouples and a temperature recording device. A strong exothermic effect of the test substance was observed. The temperature of the test substance reached 400 °C at an oven temperature of 314 °C. It demonstrated that the self-ignition temperature of the test substance is 314 °C. After the experiment, the test substance had turned into a charred residue. It indicated that the test substance had been decomposed and/or reacted during the experiment. Based on the study results, the self-ignition temperature of FAT 40854/A was 314 °C.

Description of key information

Test substance is self-ignitable at 314 °C.

Key value for chemical safety assessment

Additional information

In a GLP-compliant study, the self-ignition temperature of FAT 40854/Awas determined according to EU method A.16using a temperature programmed laboratory oven, a stainless steel wire mesh cube, NiCr/NiAl thermocouples and a temperature recording device. A strong exothermic effect of the test substance was observed. The temperature of the test substance reached 400 °C at an oven temperature of 314 °C. It demonstrated that the self-ignition temperature of the test substance is 314 °C. After the experiment, the test substance had turned into a charred residue. It indicated that the test substance had been decomposed and/or reacted during the experiment. Based on the study results, the self-ignition temperature of FAT 40854/A was 314 °C. The result of thisstudy is not sufficient for classification in accordance with CLP.


In another supporting study, FAT 40854/C is considered “not a self-heating substance”.
