1.1 These test methods cover the physical testing of gypsum panel products.

1.2 The test methods appear in the following order:


These test methods cover the physical testing of gypsum panel products. The test methos appear in the following order: (1) flexural strength (Method A); (2) core, end, and edge hardness (Method A); (3) nail pull resistance (Method A); (4) humidified deflection; (5) end squareness; (6) nominal thickness; (7) recessed- or tapered-edge depth; (8) width; (9) length; (10) water resistance of core-treated water repellant gypsum panel products; and (11) surface water resistance of gypsum panel products with water-repellant surfaces. For use in these test methods, a sample shall consist of gypsum panel products. Flexural properties of gypsum panel products are evaluated by supporting the specimen near the ends and applying a transverse load midway between the supports. The core, end, and edge hardness of gypsum panel products is evaluated by determining the force required to push a steel punch into the area of test. The ability of gypsum panel products to resist nail pull-through is evaluated by determining the loaded required to push a standard nail head through the product. The humidified deflection of gypsum panel products is evaluated by supporting a specimen that has been cut with the long dimension perpendicular to the machine detection, supported horizontally, and subjected to high humidity.
