- Guideline:
- EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))

- Principles of method if other than guideline:
- In every ignition test, a small portion of the flammable substance under test was introduced into an open conical flask (Erlenmeyer flask). The flask was heated in an electric furnace and it was observed whether ignition takes place at the prevailing temperature. Finally, any vaporizable components left in the flask were blown out with air. An ignition was observed at a temperature of 560 °C at a sample size of five drops. Proceeding from this temperature, the lowest result in the main test run was found to be 555 °C. A repeat test was performed using fresh ignition vessels. The lowest result in the repeat test was found to be 550 °C. The barometric pressure was 980 hPa at the time of the test runs.
Bearing in mind the significance of the ignition temperature for risk assessment, the result is not to be reported as the mean, but as the lowest value, where no ignition occurs. - GLP compliance:
- yes (incl. QA statement)
- Auto-ignition temperature:
- 545 °C
- Atm. press.:
- 980 hPa
- Remarks on result:
- other:
- Conclusions:
- The auto ignition temperature of ‘N-1,4-dimethylpentyl-N’-phenyl-p-phenylenediamine' is specified as 545 °C when tested according to EC Test Procedure A 15 (DIN 51794).
- Executive summary:
The auto ignition temperature of ‘N-1,4-dimethylpentyl-N’-phenyl-p-phenylenediamine' is specified as 545 °C when tested according to EC Test Procedure A 15 (DIN 51794).

Additional information
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
