Results and discussion
Relative self-ignition temperature (solids)
- Key result
- Remarks on result:
- no self-ignition observed up to the melting point
Any other information on results incl. tables
The plots of the oven temperature and sample temperature versus time are shown in Figure 6. No endothermic or exothermic effect of the test item was observed between 20°C and 165°C. It demonstrated that the test item is not self-ignitable. After the experiment, the test item had turned into an off white/brown residue and 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
- Conclusions:
- The self-ignition temperature of Phenyl Phosphonic Acid was determined using a temperature programmed laboratory oven, a stainless steel wire mesh cube, NiCr/NiAl thermocouples and a temperature recording device.
Based on the results obtained the test item is considered ‘not self-ignitable’.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
