Standard Test Method for Measuring Surface Water Absorption of Overlaid Wood-Based Panels

Importancia y uso:

3.1 Water absorptiveness through the surface of an overlaid panel is a function of various characteristics of the overlay and substrate, including overlay resin content, thickness of the overlay, porosity, and permeability.

3.2 This test method is useful in comparing the water absorption characteristics of different overlaid panel products. The results from this test method are influenced by both the performance of the overlay system and the panel substrate. Therefore, the results are appropriate for comparison of the relative performance of an overlay system when tested over similar or matched panel substrates.

Note 1: Panel attributes that may influence water absorption include, but are not limited to, panel type, wood species, face veneer thickness and grade, preoverlay surface treatment such as sanding, particle geometry and compaction ratio.
