Reference

Endpoint:

relative self-ignition temperature (solids)

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

other: UN N.4. Test Method for Self-Heating Substances

Version / remarks:

2015

Deviations:

no

GLP compliance:

yes

Relative self-ignition temperature:

> 140 °C

Remarks on result:

no self ignition observed under the test conditions

Some exothermic effects of the test item by self-heating were observed at the start of the measurement.  During these effect the test item did not exceeds the oven temperature by 60°C.  According to the guideline, the test is positive when the sample temperature exceeds the oven temperature by 60°C during the 24 hour testing time. Based on this, the result is considered negative and it demonstrated that the test item is “not a self-heating substance”. According to the UN guideline, no further testing is required. After the 24 hours testing, a small broad exothermic effect was observed. During this effect the test item reached a temperature of 153.7°C

Conclusions:

From the negative result obtained at 140°C using a 10 cm sample cube, it was concluded that the substance is not a self-heating substance with the self-ignition temperature being > 140°C.

Description of key information

From the negative result obtained at 140°C using a 10 cm sample cube, it was concluded that the substance is not a self-heating substance with the self-ignition temperature being > 140°C. As the self-ignition temperature was not determined based on the guideline requirement no key value for chemical safety assessment is available.
