Administrative data
Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 1998-06-16 to 1998-07-29
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.16 (Relative Self-Ignition Temperature for Solids)
- GLP compliance:
- yes
- Relative self-ignition temperature:
- >= 367 °C
- Remarks on result:
- other: The exothermal reaction occurred at 135 °C and the temperature of the test substance was permanently above the oven temperature until the maximum of 416 °C.
- Conclusions:
- The relative self ignition temperature of Reactive Navy 63805 is 367 °C, which is above the decomposition temperature of 140 °C.
- Executive summary:
A study was performed in accordance to the EU method A.16 and in compliance with GLP. The exothermal reaction occurred at 135 °C and the temperature of the test substance was permanently above the oven temperature until the maximum of 416 °C. Therefore, the relative self ignition temperature for Reactive Navy is 367 °C, which is above the decomposition temperature of 140 °C. No self-ignition up to the decomposition temperature of 140 °C could be observed.
Reference
The exotherm reaction of the test substance occurs at a temperature of about 135 °C and the temperature of the test substance was permanent over the oven temperature until the maximum temperature of 416 °C. The relative self ignition temperature was determined to be 367 °C.
Description of key information
A study was performed in accordance with EU method A.16 (Relative Self-Ignition Temperature for Solids) in compliance with GLP to determine the self-ignition temperature of the test substance Reactive Navy FC63805. The self-ignition temperature was determined to be 367 °C, which is above the decomposition temperature of 140 °C.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 367 °C
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).
