Endpoint:
auto-ignition temperature (liquids)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
The study was conducted between 21 March 2016 and 14 April 2016.
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))
Deviations:
no
Qualifier:
according to
Guideline:
DIN 51794 (Testing of mineral oil hydrocarbons - Determination of ignition temperature)
Deviations:
no
GLP compliance:
no
Specific details on test material used for the study:
Lot No.: SC00012329
Aspect: yellow to brownish yellow liquid
Auto-ignition temperature:
250 °C
Atm. press.:
101.3 kPa
Conclusions:
The lowest temperature giving a positive effect was 254 °C. The injected volume was 200 µL, the ignition delay was 10 s. At a temperature of 249 °C no ignition was observed. Therefore, after rounding-off to the next lower multiple of 5 °C, the auto-ignition of Citrathal Concentrate S TW was 250 ± 10 °C.
Executive summary:

The auto-ignition temperature of Citrathal Concentrate S TW was determined in a SUR BERLIN oven, equipped with a 250 mL glass ignition vessel according to DIN 51794.

The lowest temperature giving a positive effect was 254°C. The injected volume was 200µL, the ignition delay was 10 s. At a temperature of 249°C no ignition was observed.

Therefore, after rounding off to the next lower multiple of 5°C the auto-ignition temperature of Citrathal Concentrate S TW was 250±10°C.

Description of key information

A commercially available auto-ignition temperature apparatus was used for the determination of the degree of auto-ignitability of Citrathal Concentrate S TW using a procedure designed to be compatible with Method A15 Auto-Ignition Temperature (Liquids and Gases) of Commission Regulation (EC) No. 440/2008 of 30 May 2008.

The test substance has an auto-ignition temperature of 250±10°C.
