Specific details on test material used for the study:

Batch Number: E00268-011-113/E00350-276
Purity: 100%
Expiration Date: March 26, 2017

Key result

Relative self-ignition temperature:

360 °C

Ignition of the test item within 5 minutes after introduction was observed with each sample volume and with each test a minimum auto-ignition temperature was obtained. The maximum deviation between the three values was < 20°C. According to the guidelines, no further testing was required.

 

The lowest temperature at which ignition of the test item occurred was 361°C. This temperature was rounded down to the nearest multiple of 5°C giving an auto-ignition temperature of the test item of 360°C.

Conclusions:

Commercially available auto-ignition temperature apparatus was used for the determination of the degree of auto-ignitability of the Substance.
The test item is auto-ignitable with an auto-ignition temperature of 360°C at 1011.2 – 1020.9 hPa.

Executive summary:

The purpose of the study was to determine the auto-ignition of the Susbtance.

The auto-ignition temperature of the test item was determined using a commercially available autoignition temperature apparatus (Chilworth Technology, Southampton, UK). The method is applicable to test items with an auto-ignition temperature in the range 75°C – 650°C. In every ignition test, liquefied test item was introduced into a preheated test vessel using a volumetric pipette. It was observed visually whether a reaction (clearly perceptible flame and/or explosion) of the sample within five minutes after introduction took place at the prevailing temperature. After each ignition test, any vaporizable components left in the flask were blown out with air (Air Products, Amsterdam, The Netherlands). To melt the test item, the test item was placed in a water bath at a temperature of approximately 37°C.

The test item is auto-ignitable with an auto-ignition temperature of 360°C at 1011.2 – 1020.9 hPa.
