- >= 1 000.6 - <= 1 007.4 hPa
- Remarks on result:
- other: Lowest measured temperature rounded to the next lowest number divisible by 5
- Conclusions:
- The auto-ignition temperature of the test item is 255°C.
- Executive summary:
The auto-ignition temperature of the test item was investigated in study conducted according to the European Commission Regulation No. 440/2008, Method A.15. The study is a GLP-compliant, guideline experimental study, available as an unpublished study report and is adequate for assessment of this endpoint.
A preliminary test, and three main tests were conducted for the calculation of the auto-ignition value, calculated by rounding the lowest measured concentration down to the next lowest number divisible by 5, according to the guideline. Based on this calculation method, the auto-ignition temperature of the test item is 255°C.
