There are various test methods for checking the strength required for wall using a dry board like a gypsum board. As example of these tests (tests to verify official required performance), there are as follows:
Structural Performance (Flexural Rigidity) of Walls Under Out-Plane Force
The ability to withstand deformation even if three adults (180 kg) apply force to the wall surface.
Structural Performance of Walls Under In-Plane Force
There is no abnormality when the building shakes due to earthquake or wind
Shock resistance (Heavyweight impact)
There is no abnormality even if an adult hits the surface of the wall
Shock resistance (Lightweight impact)
There is no abnormality even if a hard object hits the surface of the wall
Yield strength against screw pulling
Screws will stay safe and not be pulled out even if furniture is fixed in place with screws.
Wall system with enhanced rigidity gA-2000EWI Strongh
It is ideal for places where more strength than a normal wall is required. For example, hallway in schools or where there is a possibility that furniture may collide when moved.
Hard-type gypsum board gTiger Super Hardh, fire resistant gypsum board gTiger BoardEType Zh, and light gauge steel framings (studs) are combined to provide a wall system with enhanced rigidity, gA-2000EWI Strongh, thus making it capable of achieving higher levels of performance and strength.
