ASTM D5572-95(2019)

Anotácia textu normy ASTM D5572-95(2019) :

This specification establishes the performance levels for adhesives to be used in finger joints in nonstructural bonded-lumber products. Such products include, but are not limited to, interior and exterior mouldings, window and door components or parts, and bonded-lumber panels. The apparatus shall consist of environmental chamber for moist-heat aging, oven with sufficient air circulation to remove moisture from the chamber, tanks for soaking and boiling, testing machines for the flexure and tension specimens, and vacuum-pressure vessel. Tests shall be conducted such as dry, soak, elevated-temperature, and temperature-humidity tests for dry-use classification and dry, boil, elevated-temperature, and vacuum-pressure tests for the wet-use classification. The adhesives shall be tested for performance which shall meet the following requirements: moisture content; specific gravities of wood species; tensile strength; wood failure for soft and hard woods; and rupture modulus.
