Key result
Auto-ignition temperature:
215 °C
Atm. press.:
ca. 1 013 hPa

Three replicate main tests were performed under atmospheric pressure.

The following lowest values were recorded:

 
 Experiment  Value (°C)  Drops used
 1  216  11
 2  216  11
 3  216  11

Difference between the lowest values of the main studies was less than 10 K, thus, the validity criterion was fulfilled.

The auto-ignition temperature is the lowest value from the lowest values measured during the Main Test, rounded down to the nearest multiple of 5 °C.

The lowest value of the auto-ignition temperature was 216 °C. This value was rounded down, thus, auto-ignition temperature of 2,5-Dimethoxytetrahydrofuran is 215 °C determined as in DIN 51794.

Conclusions:
The lowest value of the auto-ignition temperature was 216 °C. This value was rounded down, thus, auto-ignition temperature of 2,5-Dimethoxytetrahydrofuran is 215 °C determined as in DIN 51794.
Executive summary:

The purpose of this study was to determine the auto-ignition temperature of the test substance in air at atmospheric pressure. The test was performed with ZPA 3 auto-ignition temperature tester according to EU-Method A.15 (referring to DIN 51794) and following GLP. The auto-ignition temperature of the test substance was determined to be 215 °C.
