Table 1. Lowest temperatures at which an ignition occurred in main test

 Main test series  Lowest temperature of an ignition (°C)  Highest temperature without an ignition (°C)  Atmopheric pressure (hPa)
 1  219  216  1021.6 - 1022.1
 2  220  216  1021.1 - 1021.4
 3  220  217  1021.7
Conclusions:
The test item has an auto-ignition temperature of 215°C.
Executive summary:

Auto-ignition was determined according to EU Method A.15, DIN 51794 and DIN EN 14522 (2017). The study was not performed under GLP, however the test facility was GLP-compliant. The study is considered to be reliable without restrictions (Klimisch 1). The auto-ignition temperature of the test item was determined to be 215 °C at 1021.1 to 1022.1 hPa.

Description of key information

Additional information

Auto-ignition was determined according to EU Method A.15, DIN 51794 and DIN EN 14522 (2017). The study was not performed under GLP, however the test facility was GLP-compliant. The study is considered to be reliable without restrictions (Klimisch 1). The auto-ignition temperature of the test item was determined to be 215°C at 1021.1 to 1022.1 hPa. According to ECHA guidance "Guidance on Information Requirements and Chemical Safety Assessment; Chapter R.7A: Endpoint specific guidance" (December 2016), the auto-ignition temperature for liquids is not used directly for classification and labeling according to regulation (EC) 1272/2008, however it can be used in the chemical safety assessment. According to DIN EN 13463 the test item is classified as temperature class T3.
