Type of information:
experimental study
Adequacy of study:
key study
Study period:

Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
Version / remarks:
Commission Regulation (EC) No 440/2008 (as amended) of 30 May 2008, Part A: Methods for the determination of physico-chemical properties.
Deviations:
no
GLP compliance:
yes (incl. certificate)
Key result
Auto-ignition temperature:
> 400 °C
Atm. press.:
98.3 kPa

Autoignition of the test substances did not occur at a temperature of >400°C. Therefore the autoignition temperature is greater than 400°C.

Conclusions:
Under the conditions of this study, there was no autoignition of Solvent Red 19T up to a temperature of 400°C. The autoignitition temperature is therefore above 400°C and the test substance can be considered non-flammable.
Executive summary:

The autoignition temperature of the test substance was investigated according to method A15. Due to its high viscosity, the material was first heated in a water bath (<100°C). A quantity of the test substance was then injected into a heated flask at temperatures of 240°C, 300°C and 400°C. No ignition was observed after 10 minutes at each temperature. A reference substance (Hexane) was also measured to ensure the correct functioning of the equipment/test.

Under the conditions of this study, there was no autoignition of Solvent Red 19T up to a temperature of 400°C.  The autoignitition temperature is therefore above 400°C and the test substance can be considered non-flammable.

Description of key information
