Conclusions:
The test substance has anauto-ignition temperature of 495°C at 1018.2 – 1019.1 hPa.
Executive summary:

The aim of the study is to determine the following physico-chemical property for

Benzenamine, N-phenyl-, reaction products with styrene and 2,4,4-trimethylpentene: Auto-ignition temperature using the following guidelines:

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

DeutschesInstitutfürNormung (DIN), DIN Guide 51794: "Determining the Ignition Temperature of Petroleum Products", May 2003.

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

 

Commercially available auto-ignition temperature apparatus was used for the determination of the degree of auto-ignitability of Benzenamine, N-phenyl-, reaction products with styrene and 2,4,4-trimethylpentene.

 

The test substance has an auto-ignition temperature of 495°C at 1018.2 – 1019.1 hPa.
