Results and discussion
Self-heating substances / mixtures
- Key result
- Test procedure:
- 100 mm sample cube at 140°C
- Max. temp. reached:
- 163
- Result:
- negative outcome (no effect observed)
Any other information on results incl. tables
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.
Applicant's summary and conclusion
- Interpretation of results:
- other: not classified based on GHS or CLP criteria
- Conclusions:
- 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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
