I. Overview
This article shows the way to test the halogenide resistance of magnesium oxide board. We used Suparna MgO boards as samples to do a 15-day test and the result was quite satisfying.
II. Summary of Test Results
|
No. |
Test Item | Test Method | Result | Conclusion |
| 1 | Halogenide Resistance | With reference to JC 688-2006 Section 6.2.7 and client’s requirement | See results |
/ |
Note:
- Pass: Meet the requirements;
- Fail: Does not meet the requirements;
- /: Not Apply to the judgment.
III. Test Description
1. Test item: Halogenide resistance
2. Sample description: See photo below
3. Test method:
Cut boards of 200*200 mm on each of the three sample MgO boards.
Put them into a constant temperature and humidity chamber with a relative humidity of 90% or more and a temperature of 30-35 °C.
Take them out after 24 hours to see if there is any water drops or moisture.
4. Test condition: 30~35℃, 90%RH, 15 days
