Results and discussion
Relative self-ignition temperature (solids)
- Key result
- Remarks on result:
- no self-ignition observed up to the melting point
Applicant's summary and conclusion
- Conclusions:
- A certain volume of the test item under the assay was placed into an oven at ambient
temperature; the temperature/time curve was recorded while the temperature of the oven was
increased up to the melting point, at a rate of approximately 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.
Three replicate tests were performed.
In the course of this study the test item 4-Nitrobenzic acid did not self-ignite up to the
melting point. Thus, no self-ignition temperature could be stated. - Executive summary:
Three consecutive tests were performed. A temperature-time curve can be seen in Figure 1.
In the course of this study the test item 4-Nitrobenzic acid did not self-ignite up to the melting
point (237 - 240 °C, based on Material Safety Data Sheet, provided by the Sponsor). Thus, no
self-ignition temperature could be stated.
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).
