Expiry date 31. Dec. 2025
Storage room temperature (20 ± 5 °C)
Stability stable under storage conditions - Key result
- Relative self-ignition temperature:
- > 400 °C
- Remarks on result:
- no self ignition observed under the test conditions
- Conclusions:
- The test item Lead Sulphate is considered as showing no self-ignition up to 400 °C under the test conditions.
- Executive summary:
The auto-flammability behaviour was determined by placing the test item into a stainless steel cube and heating from room temperature to an oven temperature of 400 °C with the ZPA-3 oven.
No increase in the temperature of the sample in comparison to that of the oven could be detected, also no signs of ignition could be observed.
Therefore, the test item Lead sulphate should be considered as showing no self-ignition up to 400°C under the test conditions.
