- Expiry date: 2013-06-16 - Key result
- Auto-ignition temperature:
- 260 °C
- Atm. press.:
- > 99 939 - < 100 816 Pa
- 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.

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.
Description of key information
The auto-ignition temperature (rounded) according to EU A.15 of Sika Hardener MH is 260 °C.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 260 °C
