Justification for data waiving:
Reason / purpose for cross-reference:
data waiving: supporting information
self-heating substances / mixtures
Type of information:
experimental study
Adequacy of study:
key study
Study period:
23 May 2016 - 02 May 2017
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 (2009)
GLP compliance:
Key result
Test procedure:
100 mm sample cube at 140°C
Max. temp. reached:
negative outcome (no effect observed)

An exothermic effect of the test substance was observed (see the figure below). During this effect the test substance reached a temperature of 163°C. According to the guideline, the test is positive when the sample temperature exceeds the oven temperature by 60°C during the 24 hour testing time. The result is therefore considered negative and no further testing is required.

After the experiment, the test item had turned into an orange brown solid residue in the cube and some test item was collected in a container that was placed below the cube. It indicated that the test item had been molten, decomposed and/or reacted during the experiment.

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