Conclusions:

Under the study conditions, the autoignition temperature of the test substance was determined to be 311°C.

Executive summary:

A study was conducted to determine the autoignition temperature of the test substance according to EU Method A.15, in compliance with GLP. The autoignition of the test substance was determined by measuring hot flame autoignition temperatures (AIT) in air at atmospheric pressure in a uniformly heated vessel. Under the study conditions, the autoignition temperature of the test substance was determined to be 311°C (Chilworth, 2017).

Description of key information

The autoignition temperature of the test substance was determined according to EU Method A.15 (Chilworth, 2017).
