Any other information on results incl. tables

The sample weight and end temperatures for the experiment are presented in the following table:

Experiment	Edge length of Cube in mm	Weight of Test Item in g	Temperature in °C	Time in hours
1	100	172.8	140	24

 

As approx. 44000 values were measured in 24 hours, not all raw data can be presented in this final report. As example, values from each full hour of measuring are stated in the table below. In the graph (see following chapter), all values are included.

Time / h	Temperature Test Item /°C	Temperature Oven / °C

No increase of the temperature in the test item of 60 °C above the oven temperature and no signs of ignition were observed in the first experiment. Therefore, no other experiments were necessary the test item N-[4-(2,4-dihydroxyphenyl)thiazol-2-yl]isobutyramide “is not classified in Division 4.2 and should not be considered for classification as self-heating substance according to CLP regulation ((EC) No 1272/2008).”

No observations were made which might cause doubts concerning the validity of the study outcome.

Therefore, the test itemN-[4-(2,4-dihydroxyphenyl)thiazol-2-yl]isobutyramide should not be classified as self-heating substance.
