Applicant's summary and conclusion

Conclusions:
The study was conducted according to procedure and demands of EU-Method A.15 and DIN 51794. The precision range which is demanded in the DIN standard was fulfilled.
All measured values show good correlation. No observations were made which might cause doubts concerning the validity of the study outcome.
Executive summary:

An auto ignition temperature of 205°C was determined. This value is the lowest value in three independent determinations.

The auto ignition temperature of NOREENAL A45756 according to EU A.15 is 205°C.
