- Key result
- Auto-ignition temperature:
- 367 °C
- Atm. press.:
- 1 013.25 hPa
- Conclusions:
- The auto ignition temperature of SIKA Hardener MTJ was determined to be 365 °C at 1013.25 hPa.
- Executive summary:
A study was conducted to determine the auto-ignition temperature of SIKA Hardener MTJ according to Regulation (EC) No 440/2008 method A.15 and DIN 51794 Three independent determinations were conducted. The auto-ignition temperature was determined to be 367 °C in all three replicates. According to the criteria as laid down in DIN 51794 the auto ignition temperature is the lowest value of the three experiments, rounded down to a whole multiple of 5 °C. Therefore, the auto ignition temperature is stated as 365 °C. The three lowest values of the main study lay within a range of 20 K. No observations were made which might cause doubts concerning the validity of the study outcome. Thus, the validation criteria were fulfilled.

*The temperature was selected at the ZPA3 corresponding to an initial oven temperature of 200 °C. Using a constant heating rate, the subsequent ignition trials were conducted every 20 ± 5 K
Main Study
The requirements for repeatability of the DIN 51794 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 below 300 °C) respectively 20 K (if auto ignition temperature is above 300 °C).
The following lowest values were recorded:
