Study period:
22 December 2017 - 07 June 2018
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
according to guideline
UN Manual of Tests and Criteria: Test N.4 (Test method for self-heating substances)
Version / remarks:
Rev. 6 (2015)
GLP compliance:
Specific details on test material used for the study:
Particle size distribution: D10 = 7.991 μm, D50 = 17.774 μm and D90 = 34.857 μm.
Key result
Test procedure:
100 mm sample cube at 140°C
negative outcome (no effect observed)

No spontaneous ignition occurred and no exothermic effect of the test item was observed. It demonstrated that the test item is “not a self-heating substance”. According to the UN guideline, no further testing is required.

After the experiment, the test item had turned into a light yellow powder. It indicated that the test item had been decomposed and/or reacted during the experiment.

Interpretation of results:
other: not classified based on GHS or CLP criteria
The substance is not a self-heating substance.
Executive summary:

In a GLP study according to UN Test N.4, a negative result was obtained using a 10x10x10 cm sample cube at 140°C. From this it was concluded that the substance is not a self-heating substance.
