Magnesium Oxide Board Testing
As with any innovative building product, manufacturers of magnesium oxide (MgO) boards must demonstrate to their customers and local authorities having jurisdiction that their products are safe and effective. Rather than second-guess the compliance requirements, which can lead to project delays, poor customer reception and loss of market share, well prepared manufacturers seek comprehensive guidance from collaborative and innovative third-party partners like ICC-ES.
ICC-ES accredited laboratories conduct tests of MgO boards for various characteristics, including but not limited to:
- Use as structural floor sheathing for wood and/or cold-formed steel framing
- Use as structural roof sheathing attached to cold-formed steel framing
- Use as wall and ceiling sheathing or floor underlayment
- Use as a substrate in interior areas
- Flexural Strength
- Freeze/Thaw Resistance
- Dimensional Tolerances
- Moisture Movement
- Water Absorption
- Compression Indentation
- Fastener Pull-Through
- Falling Ball Impact
- Shear Bond Strength
- Humidified Deflection
- Flame Spread
- Corrosion Effects
- Concentrated Static and Impact Loads
- Transverse Wind Load
- Fastener Capacity
- Diaphragm Performance
- Long Term Durability
- Density
- Fire Resistance
- Racking Shear Resistance
We create tailored test plans that capture specialized requirements for innovative products, such as those found in the ICC-ES Acceptance Criteria. Below is a list of standards or criteria that may be included in test plans for gypsum wallboard:
