Flexural strength testing of Wood is accomplished with three point bend fixtures. Wood products are a common engineering material used in the construction and furniture industry. The strength of wood is influenced by factors, including the specific type of wood, loading type, loading direction and duration, moisture content and temperature. Test Standards cover testing methods to determine properties including flexure strength, tensile strength and shear strength. To ensure that failure of the specimen arises from tensile or compressive stress, and not shear stress, many testing standards require a minimum span-to-depth ratio of 14.
