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 laboratories are accredited to the ISO 17025 standard, which ensures that you and your customers can rely on the validity of our results. Our team also understands how important test results are for your business goals and objectives — all our team members work together with you to efficiently conduct tests and prepare the test reports you need. We 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. Test plans help ensure your innovative product has a clear path through the certification process with agreement from all participants.
