Key result

Remarks on result:

not determinable

Remarks:

test item can be considered to have no auto ignition temperature till 650°C under the test conditions.

Determination of the viscosity

The test item was visually compared with the standard liquid Viscosity (50 mPa*s). The viscosity of the test item was below 50 mPa*s.

Pre-Determination

The ignition attempts of the pre-determination program are presented in the following table.

No ignition occurred up to 376.4 °C. Therefore, the pre-test was continued with a selected temperature of 498 °C at the ZPA3. As no ignition occurred, the pre-test was continued with a selected temperature of 585 °C. The determination was performed up to 651.1°C without finding an ignition. Using a constant heating rate, the subsequent ignition trials were conducted every 20 ± 5 K.

The ignition trials were conducted on 02. Aug. 2018

Atmospheric pressure during the pre-test was 1005.6 mbar.

Conclusions:

The test item can be considered to have no auto ignition temperature till 650°C under the test conditions (EU-Method A.15 and DIN 51794)

Executive summary:

As no ignition was found during the Pre-Determination Program from 200°C till 650°C, no auto-ignition temperature according to EU A.15 of the test item can be stated.

The test item can be considered to have no auto ignition temperature till 650°C under the test conditions.

The study was conducted according to procedure and demands of EU-Method A.15 and DIN 51794.

No observations were made which might cause doubts concerning the validity of the study outcome.
