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

Note:

  • Pass: Meet the requirements;
  • Fail: Does not meet the requirements;
  • /: Not Apply to the judgment.

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
