Key result
Auto-ignition temperature:
330 °C
Atm. press.:
>= 1 010.4 - <= 1 016.1 hPa

Preliminary test

The estimated auto-ignition temperature was 350°C.

Main study

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 wasrequired.

The lowest temperature at which ignition of the test item occurred was 330°C. This temperature was a multiple of 5°C and therefore given as the auto-ignition temperature of the test item.

Conclusions:
Commercially available auto-ignition temperature apparatus was used for the determination of the degree of auto-ignitability of Hepteen Base®.
The test item is auto-ignitable with an auto-ignition temperature of 330°C at 1010.4 – 1016.1 hPa.
Executive summary:

A study was conducted on Hepteen Base ® using auto-ignition temperature apparatus (Chilworth Technology, Southampton, UK) to determine if it is auto-ignitable and at what temperature. The experiment was carried out in accordance with the following test guidelines in an accredited GLP laboratory.

 European Community (EC), EC no. 440/2008, Part A: Methods for the Determinationof Physico-Chemical Properties, Guideline A.15: “Auto-Ignition Temperature (Liquids and Gases)”, Official Journal of the European Union no. L142, May 31,2008.

Deutsches Institut für Normung (DIN), DIN Guide 51794: "Determining theIgnition Temperature of Petroleum Products", May2003.

International Electrotechnical Commission (IEC), IEC standard 79-4: "Electrical Apparatus for Explosive Gas Atmospheres, Part 4, Method of Test for Ignition Temperature",1975.

The results obtained concluded that the test material is auto-ignitable with an auto-ignition temperature of 330°C at 1010.4 – 1016.1 hPa.
