- Deviations:

- Principles of method if other than guideline:
- The substance under test is placed in an oven (Grewer oven) at room temperature; the temperature/time curve relating to conditions in the centre of the sample is recorded while the temperature of the oven is increased to 400 °C, or to the melting point if lower. The temperature of the oven at which the sample temperature reaches 400 °C by self-heating is called the self-ignition temperature. Testing in the Grewer oven is a screening procedure for self-heating substances.

Results and discussion
For thermal stability study
- Test substance thermally stable:
- yes
Operating temperature
- Operating temp.:
- 20 - 400 °C
Any other information on results incl. tables
No exothermal event, only the endothermal melting at 170 °C was observed.
Testing in the "Grewer oven" is a screening procedure for "self-heating substances". If T(onset) >= 220 °C (or no exothermal onset is detectable because of melting) testing according to UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, 5th Edition, 2009 is not required.
Applicant's summary and conclusion
- Conclusions:
- Adipic acid dihydrazide has no self-ignition and no self-heating properties.
- Executive summary:
A screening test in the "Grewer oven" for possible self-heating properties was performed.
No exothermal event, only the endothermal melting at 170 °C was observed.
If the onset temperature for exothermic reactions is >= 220 °C or no exothermal onset is detectable because of melting, no further testing according to UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, 5th Edition, 2009 is required.
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).
