- GLP compliance:
- yes (incl. QA statement)
- Specific details on test material used for the study:
- No further details specified in the study report.
- Key result
- Auto-ignition temperature:
- 370 °C
- Atm. press.:
- > 996.1 - < 996.7 mBar
- Conclusions:
- The requirements for repeatability of the DIN standard are stated as follows: Three lowest values of the main test have to lie within a range of 10 K (if auto ignition temperature is above 300 °C).
The lowest value of the auto ignition temperature is 373.08 °C. This value was determined using 9 drops test item. The test item showed auto ignition after 36 seconds.
The auto ignition temperature (result of determination) is the lowest value from the lowest values of the three experiments, rounded down to a whole multiple of 5 °C. Therefore, the auto ignition temperature is stated as 370 °C. - Executive summary:
Determination of the auto ignition temperature of LUMULSE GMT-K according to EU A.15
Findings and Results:
The auto ignition temperature was determined in three independent determinations. A lowest value of the main test of 373.08 °C was found.
Therefore, the auto-ignition temperature according to EU A.15 (rounded down to a whole multiple of 5 °C) of LUMULSE GMT-K is stated as: 370 °C.
Reference
Determination of the viscosity
The test item was visually compared with the standard liquid Viscosity (50 mPa/s).The viscosity of the test item was below 50 mPa/s.
