Endpoint:
relative self-ignition temperature (solids)
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is a solid having a melting point <= 160°C

Principles of method if other than guideline:
Modifications to the EU A.16 Method: A heating rate of 1.0-1.2 deg C/min or 0.6 deg C/min is used instead of 0.5 deg C/min due to an alternative Swiss Chemical Industry method and technical restriction of the apparatus used. Cylindric wire baskets with 0.2 mm openings are used.

Key result
Remarks on result:
no self ignition observed under the test conditions

Heating rate: 1.0 °C/min

The sample is heated from room temperature (about 20 deg C) to +/- 135 °C (nearby the melting point). The sample shows no self-ignition to 400°C in the test run.

Conclusions:
In conclusion, the tested substance T001159 is not auto-flammable up to the temperature applied in the test run. The substance has no relative self-ignition temperature.

Description of key information

The auto-flammability test didn't need to be conducted since the melting point of the substance is =< 160°C.

From a supporting study (assigned K4 ) from the Janssen Process Safety Center in 1985 based on a modified EC A.16 guideline, the VDI Guideline 2263 Part 1: Autoignition-Testing as per Grewer and the method from the ESCIS Expert Commission for Safety in the Swiss Chemical Industry, Booklet 1 ''Sicherheitstests fur Chemikalien'', it could be derived that no self-ignition temperature was observed for T001159.

Key value for chemical safety assessment

Additional information

In a supporting study (assigned K4) carried out by the Janssen Process Safety Center (in 1990), the Minimum Ignition Temperature determined in the BAM oven for T001159 was determined to be 400°C.
