Relative self-ignition temperature:
398 °C

Any other information on results incl. tables

Results of the three consecutive tests were 397.5 °C, 398.7 °C and 400.9 °C. The relative self-ignition temperature of Leuco Sulfur Red 14 was found to be 398 °C.

Applicant's summary and conclusion

Conclusions:
The relative self-ignition temperature of Leuco Sulfur Red 14 was determined to be 398 °C
Executive summary:

The objective of the study was to evaluate the relative self-ignition temperature of Leuco Sulfur Red 14.

A certain volume of the test item under the assay was placed into an oven at ambient temperature; the temperature/time curve was recorded while the temperature of the oven was increased up to 400 °C, at a rate of approximately 0.5 °C/min. For the purpose of this test, the temperature of the oven at which the sample temperature reachesby self-heating is called the self-ignition temperature.Three replicate tests were performed. The relative self-ignition temperature ofLeuco Sulfur Red 14was determined to be 398 °C.
