This standard is the core test method for determining the density of wood, primarily specifying the measurement of density under four different conditions: density at corresponding moisture content, air-dry density, oven-dry density, and basic density. It applies to defect-free small specimens, with its core principle being the precise measurement of the specimen's mass and corresponding volume to calculate the density value. According to the standard, the main instruments involved are precision analytical balances and vernier calipers or micrometers for measuring specimen dimensions.
