Auto flammability

Link to relevant study record(s)

Reference

Endpoint:

relative self-ignition temperature (solids)

Type of information:

experimental study

Adequacy of study:

key study

Study period:

25th January 2008

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

study well documented, meets generally accepted scientific principles, acceptable for assessment

Qualifier:

according to guideline

Guideline:

EU Method A.16 (Relative Self-Ignition Temperature for Solids)

Principles of method if other than guideline:

Two methods are used, both in line with EU Method A.16.

In the first test, the substance is heated in an oven up to 400 degrees centigrade in a steel autoclave.

In the second test, the exothermic reaction is measured with Differential Scanninc Calorimetry.

GLP compliance:

not specified

Specific details on test material used for the study:

N,N-Dimethyl-N,N-dioctylammoniumchlorid (dimethyldioctylammonium chloride).
(Mischung) Bardac 18-50 WT; Bdac 18-50 WT.
Silab-sample-Nr: 08-009.

Key result

Relative self-ignition temperature:

>= 400 °C

Remarks on result:

no self ignition observed under the test conditions

Remarks:

endothermic reaction above 139 °C. Test 1.

Key result

Relative self-ignition temperature:

>= 400 °C

Remarks on result:

no self ignition observed under the test conditions

Remarks:

Exothermic reactions detected throughout the experiment: 1. Several exothermic reactions detectable above 155 degrees centigrade with a total energy of ~-12 J/g (peak maximum at 205 degrees centigrade) 2. Several exothermic reactions detectable above 300 degrees centigrade with a total energy of ~-31 J/g (peak maximum at 337 degrees centigrade) 3. Single exothermic reaction with an energy of >-13 J/g detectable above 366 degrees centigrade.

Conclusions:

No self-ignition is detected up to 400 degrees centigrade.

Executive summary:

In two different tests, no self-ignition is detected up to 400 degrees centigrade. During heating, a number of exothermic reactions take place above 139 degrees centigrade, and these are further analysed using a DSC method for specific energies and temperature levels.
