ASTM's wood standards are instrumental in the evaluation and testing of the physical and chemical properties of a wide range of wood and wood-based products. Wooden materials covered here include timber, lumber, wood-base fibers, commercial softwoods and hardwoods, wood preservatives, laminated timber, and composite lumber to name a few. These materials are notably used in the fabrication of construction materials such as structural panels and members, construction poles, and log buildings. These wood standards are helpful in guiding wooden material and product manufacturers and end-users in their proper testing and fabrication procedures to ensure acceptable quality towards safe and satisfactory use.
