- Expiration date of the lot/batch: August 04, 2020
- Purity test date: Quality certificate dated August 04, 2017
STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: Ambient temperature (10°C to 30°C)
FORM OF TEST MATERIAL
- Purity: 15.06 % w/w platinum
- Form: Liquid
- Appearance: Reddish liquid - Remarks on result:
- no flash point - measurement carried out until boiling temperature
- Remarks:
- No flash point was detected up to the beginning of boiling. The test was stopped at 106°C.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- No ignition was detected up to the beginning of boiling. The test was stopped at 106°C.
- Executive summary:
Nau (2017) is a GLP-compliant study following EU method A9. It is reliable without restrictions and can be used as the key study for this endpoint. No ignition was detected up to the beginning of boiling. The test was stopped at 106°C.
Reference
The preliminary test with 2 mL test item (starting temperature: 20 °C) showed no ignition up to 100°C. At 100°C the test was stopped.
The preliminary test with 4 mL test item (starting temperature: 100°C) showed no ignition up to 106°C. At 106°C (oven temperature) boiling was observed. Afterwards the test was stopped.
Due to the ongoing boiling the composition of the test item changes. These changes will become more and more pronounced with increasing temperatures. Additionally, if the temperature of the oven is above the boiling point a major part of the test item will vaporize after being put into the apparatus and hence fill the space above the remaining test item with vapour: in exchange of air no flammable vapour/air mixture is present.
Due to the results of the preliminary test the main test was not performed.
