Table 5 summary of result

Parameter	Value (°C)
Lowest value of test series 1	274
Lowest value of test series 2	275
Lowest value of test series 3	275
Lowest value of all test series	274
Absolute deviation of the lowest value (1.5%)	4.1
Auto ignition temperature	270

According to DIN EN 14522 the lowest value of all test series (274°C) was reduced by the deviation value based on the precision of the method (rel. 1.5% = 4.1°C). The resulting value was rounded to the next integral number (270°C).

Conclusions:

An auto-ignition temperature value of 270°C at 968.4 - 976.2 hPa was determined for the substance using a relevant test method. The result is considered to be reliable.
