Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 15 February 2017 - 9 June 2017
- 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)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Key result
- Remarks on result:
- no self ignition observed under the test conditions
- Remarks:
- (up to 400°C)
- Conclusions:
- The self-ignition temperature of yttrium metal was investigated according to the EU A.16 method in compliance with GLP. No self-ignition temperature was observed up to 400°C (corrected value). The temperature of the test item sample followed the temperature of the oven.
Reference
At the start of the test, the test item was a mettalic grey powder.
At the end of the test, the cube was full of grey powder.
The temperature of the test item sample followed the temperature of the oven up to the highest oven temperature reached (400°C).
Similar observations were made in the two assays.
Description of key information
Based on an experimental study (Demangel, 2017, Klimisch score 1) performed in accordance with EU method A.16 and in compliance with GLP, it is concluded that the test item has no self-ignition temperature up to 400°C (corrected value). Within this test, the temperature of the test item sample followed the temperature of the oven. Results of this study are reliable without restrictions.
Key value for chemical safety assessment
Additional information
The test item has no self-ignition temperature up to 400°C.
