Value |
Lowest value of test series 1: |
346 °C |
Lowest value of test series 2: |
349 °C |
Lowest value of test series 3: |
349 °C |
Lowest value of all test series: |
346 °C |
Absolute deviation of the lowest value (1.5%): |
5.2 °C |
Auto-ignition temperature: |
341 °C |
According to DIN EN 14522 the lowest value of all test series (346 °C) was reduced by the deviation value based on the precision of the method (rel. 1.5% = 5.2 °C). The resulting value was rounded to the next integral number (341 °C).
Description of key information
Auto-flammability 341°C at 955-974 hPa (EU Method A.15)
Key value for chemical safety assessment
Additional information
A measured auto-ignition temperature of 341°C at 955 -974 hPa was determined for L6 in accordance with EU Method A.15 and in compliance with a known quality system (ISO 9001:2008). The result is considered to be reliable and is selected as key study.
