Applicant's summary and conclusion

Conclusions:
The substance, 2,5-diphenyloxazole was evaluated in regards to it's auto flammability point via a GLP laboratory. It was determined via use of Carbolite flask heater that the substance auto flammability point was 540 +/- 5 °C at 101.4 +/- 0.1 kPa.
Executive summary:

The substance, 2,5-diphenyloxazole was evaluated in regards to it's auto flammability point in accordance with EU Method A.15 via a GLP laboratory. The test flask was heated in a flask heater. Aliquots of test item (tested as received) were dropped into the flask which was observed for signs of ignition over a 300 second period. This procedure was repeated, varying the sample size, as necessary, until the lowest temperature at which ignition, if any, occurred within 300 seconds of insertion, was determined. It was determined via use of Carbolite flask heater that the substance auto flammability point was 540 +/- 5 °C  at 101.4 +/- 0.1 kPa.
