295 °C

Additional information

The study performed in experimental laboratory (Paulus,2009, LAUS), dedicated to estimate the auto ignition of the test material 3 -mercapropropanoic acid has been chosen as a key study. The auto ignition temperature has been determined to be 295 °C at 99299 Pa. Study was performed according to procedure and demands of EU-Method A.15, Directive 440/2008/EC dated 31.05.2008, "Auto Ignition Temperature" and DIN 51794.

Another study (Rampy, 1973, Dow) reports the auto ignition temperature to be 350 °C; the report was not performed according to current standards but qualitatively supports the key study.
