CAS 101-80-4 - Key result
- Relative self-ignition temperature:
- > 192 °C
- Remarks on result:
- other: No ignition was observed up to 192°C ( the melting point of the substance as was determined in study reference 10/051-344AN).
- Conclusions:
- The substance is not considered to have a relative self ignition temperature below the melting point. The substance is therefore not classified for this endpoint hazard.
- Executive summary:
The substance is not considered to have a relative self ignition temperature below the melting point. The substance is therefore not classified for this endpoint hazard. In compliance withAnnex V A.16 guideline "Relative Self-Ignition Temperature", Paragraph1.4. Principle of the Method, it is stated that:
"A certain volume of the substance under test is placed in an 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, at a rate of 0,5 °C/min.
For the purpose of this test, the temperature of the oven at which the sample temperature reaches 400 °C by self-heating is called the self-ignition temperature.As the substance melted prior to achieiving any self ignition, it is deemed that the substance does not pose a hazard for this endpoint.
Reference
Three replicate tests were performed. The relative self-ignition temperature of 4,4-Diaminodiphenylether: no ignition was observed up to 192°C(melting point was determined in 10/051-344AN study).
Description of key information
The auto-flammability of the test item was determined using the EU Method A.16 under GLP conditions.
No ignition was observed up to 192°C (melting point).
The substance is not considered to have a relative self ignition temperature below the melting point. The substance is therefore not classified for this endpoint hazard.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 192 °C
