lowest value for main test:	383°C
lowest value for first retest:	385°C

 

Lowest value of all test series: 383°C.

The stated value is the lowest of all single tests rounded down (according to the prescribed rounding procedure) to the next lowest multiple of 5 K.

Auto Ignition Temperature of the sample: 380°C

The inaccuracy of the test was ±1 K.

Conclusions:

An auto-ignition temperature value of 380°C at 1015 - 1020 hPa was determined for the substance using a relevant test method and in compliance with GLP. The result is considered to be reliable.
