Specific details on test material used for the study:
Introduction
Explosive substances and substances which ignite spontaneously in contact with air at ambient temperature should not be submitted to this test. The test procedure is applicable to gases, liquids and vapours which, in the presence of air, can be ignited by a hot surface. The auto-ignition temperature can be considerably reduced by the presence of catalytic impurities, by the surface material or by a higher volume of the test vessel.

Method
Type of appliance Apparatus for determination of auto-ignition temperature according to DIN 51794. The auto-ignition temperature, as obtained by this method, is the minimum ambient temperature expressed in [°C] at which a certain volume of a substance ignites under defined conditions.

Measurements:
The temperature of the oven and the sample were continuously recorded while the temperature of the oven was increased to approximately 550 °C at a rate of about 3-5 K/min. Then the test item is given drop by drop with pipette by cylinder hole into Erlenmeyer flask.
Whether the heat development is due to a reaction of the test item with oxygen or due to exothermic decomposition is not relevant for the test. Self-heating, with the possible consequence of self-ignition, occurs, when the rate of heat production exceeds the rate of heat loss to the surroundings.
Key result
Relative self-ignition temperature:
> 550 °C
Remarks on result:
other: No auto-ignition until 550 °C

None

Conclusions:
The auto-ignition temperature of FAT 40032/G was determined as: No auto-ignition up to 550 °C.
Executive summary:

The determination of the auto-ignition temperature of FAT 40032/G was performed in accordance with the OECD Directive Annex V of 67/548 Test A 15 - Auto-ignition temperature for liquids. The auto-ignition temperature of FAT 40032/G: No auto-ignition up to 550 °C.

Description of key information

The auto-ignition temperature of FAT 40032/G: No auto-ignition up to 550 °C.

Key value for chemical safety assessment
