Key result
Auto-ignition temperature:
435 °C
Atm. press.:
>= 101 630 - <= 102 000 Pa

 Result

The requirements for repeatability of the DIN standard are stated as follows: Three lowest values of the main study have to lie within a range of 10 K (if auto ignition temperature is above 300 °C).

The following lowest values were recorded:

The lowest value of the auto ignition temperature is 439 °C. This value was determined using 5 drops of test substance. The test substance showed auto ignition after 18 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 435 °C.

The three lowest values of the main study lay within a range of 10 K (as required for auto ignition temperatures above 300°C.

Conclusions:
The auto ignition temperature of ethylphthalyl ethyl glycolate is stated as 435 °C at 102,000 Pa.
