Link to relevant study record(s)

Reference

Endpoint:

auto-ignition temperature (liquids)

Type of information:

experimental study

Adequacy of study:

key study

Study period:

01.08.2017

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

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. QA statement)

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

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.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
