Table 5: summary of result

Parameter	Value
Lowest value of test series 1:	355°C
Lowest value of test series 2:	363°C
Lowest value of test series 3:	361°C
Lowest value of all test series:	355°C
Absolute deviation of the lowest value (1.5%):	5.3°C
Auto-ignition temperature:	350°C

 

According to DIN EN 14522 the lowest value of all test series (355°C) was reduced by the deviation value based on the precision of the method (rel. 1.5% = 5.3°C). The resulting value was rounded to the next integral number (350°C).

Conclusions:

An auto-ignition temperature value of 350°C at 966-970 hPa was determined for the substance using a relevant test method and in compliance with a known quality system. The result is considered to be reliable.
