Wood-based panels - Determination of moisture resistance under cyclic test conditions

This document establishes the method for assessing the water resistance of engineered wood panels when subjected to cyclic test conditions. The procedure defines specific requirements for specimen preparation, conditioning, and the immersion process to ensure consistent and comparable results across different laboratories. It focuses on determining the dimensional stability and swelling characteristics of the panels after repeated exposure to water and drying cycles. The standard outlines the precise duration for the conditioning phases and the specific criteria for measuring the resulting changes in thickness and dimensions. It is applicable to a wide range of panel products used in interior and exterior applications where moisture exposure is a concern. By following the prescribed protocol, manufacturers and testing facilities can accurately evaluate the performance of wood-based materials under realistic environmental stress. The method provides a systematic approach to quality control and product development, ensuring that panels meet the necessary durability requirements for their intended use in construction and furniture manufacturing.
