Key result

Test procedure:

100 mm sample cube at 140°C

Result:

negative outcome (no effect observed)

After the experiment the test material had turned into a orange/brown residue.

Interpretation of results:

other: not classified based on GHS or CLP criteria

Conclusions:

The substance was determined to be not self-heating.

Executive summary:

In a GLP study according to UN Test N.4, a negative result was obtained using a 10 cm sample cube at 140°C. From this it was concluded that the substance is not self-heating.
