Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Reference
Endpoint:
flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.9 (Flash-Point)
Deviations:
no
Qualifier:
according to guideline
Guideline:
ISO 3679 (Determination of flash point - Rapid equilibrium closed cup method)
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Type of method:

Flash point apparatus:
other: Normalab NPV310, Inv. No. 49405775
Specific details on test material used for the study:
SOURCE OF TEST MATERIAL
- 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.

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.
