Endpoint:
relative self-ignition temperature (solids)
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is a solid having a melting point <= 160°C
Endpoint:
auto-ignition temperature (liquids)
Type of information:
experimental study

Description of key information

Auto-ignition temperature: 470 to >515 °C at 1013 mBar

(several materials were tested according to DIN 51794, ASTM E659)

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
470 °C

Additional information

The reported values for Auto-ignition temperature for liquid or low-melting Tar acids, xylenol fraction range from 470 °C to >515 °C at 1013 mBar. Testing for solid Tar acids, xylenol fraction does not need to be conducted because the substance has a melting point <= 160 °C and so self-heating is excluded.
