Specific details on test material used for the study:

- Batch no.: 10191-AKm
- Purity. 100.5 % (aldimine titration)
- Expiry date: 2013-06-16

Key result

Auto-ignition temperature:

260 °C

Atm. press.:

> 99 939 - < 100 816 Pa

Lowest Values Main Study

Experiment	Value	Ignition delay	Drops used
First Experiment	289 °C	18 seconds	2
Second Experiment	299 °C	10 seconds	2
Third Experiment	267 °C	99 seconds	8
Fourth Experiment	262 °C	84 seconds	8
Fifth Experiment	262 °C	92 seconds	8

 

The results of the first and the second experiment were discarded and the lowest value of the auto-ignition temperature is 262 °C. This value was determined using 8 drops test item. The test item showed auto-ignition after 84 seconds. The auto-ignition temperature (result of the 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 260 °C.

Conclusions:

The auto-ignition temperature (rounded) according to EU A.15 of Sika Hardener MH is 260 °C.

Executive summary:

The determination of the auto-ignition temperature of Sika Hardener MH was performed according to EU Method A.15. Five independent determinations were performed. An auto-ignition temperature of 262 °C was determined. This value is the lowest value of three independent determinations and the higher temperatures of two determinations were discarded. The auto-ignition temperature (rounded) according to EU Method A.15 of Sika Hardener MH is 260 °C.
