- Specific details on test material used for the study:
- - Name: Magnesium hydroxide
- Batch no. 20BR0026
- CAS No.: 1309-42-8
- Purity: 99.9 %
- Expiry date: 31 January 2012
- Storage Room Temp. in the dark - Key result
- Remarks on result:
- no self ignition observed under the test conditions
- Conclusions:
- Based on the results obtained the test substance is considered not self-ignitable.
- Executive summary:
The self-ignition temperature of magnesium hydroxide was determined using a temperature programmed laboratory oven, a stainless steel wire mesh cube, NiCr/NiAl thermocouples and a temperature recording device (EU Method A.16). The oven was heated from 20 °C - 400 °C at a rat of 0.5 °C/minute.
No endothermic or exothermic effect of the test substance was observed over the temeprature range - indicated that the test substance is not considered self-ignitable.
Reference
Plotting of the oven and sample temperature versus time showed no endothermic or exothermic effect between 20 °C and 400 °C, demonstrating that the test substance is not self-ignitable.
Description of key information
The test substance is considered "not self-ignitable".
Key value for chemical safety assessment
Additional information
The self-ignition temperature of magnesium hydroxide was determined using a temperature programmed laboratory oven, a stainless steel wire mesh cube, NiCr/NiAl thermocouples and a temperature recording device (EU Method A.16). The oven was heated from 20 °C to 400 °C at a rate of 0.5 °C/minute.
No endothermic or exothermic effect of the test substance was observed within the temperature range, indicating that the test substance is not considered self-ignitable.
