This dataset documents the following parameters related to the perpendicular-to-grain tensile strength of Black Castanopsis (Castanopsis nigrescens): serial number of the dataset entry, logbook serial number, specimen serial number, specimen width, specimen thickness, failure area, radial failure load, tangential failure load, moisture content during testing, radial perpendicular-to-grain tensile strength measured during testing, radial perpendicular-to-grain tensile strength at 15% moisture content, tangential perpendicular-to-grain tensile strength measured during testing, and tangential perpendicular-to-grain tensile strength at 15% moisture content. All measured physical and mechanical properties of this wood species directly reflect its strength and other mechanical characteristics, providing reliable scientific data for wood utilization and the formulation of wooden structure codes. This database contains both the physical and mechanical test data and the corresponding test methods. Please refer to Attachment 1 for the Chinese National Standard GB 1927~1943-91 *Test Methods for Physical and Mechanical Properties of Wood*, and Attachment 2 for the definitions of each item in wood physical and mechanical testing.
