Full Description
This practice is applicable to the sampling of wood for all chemical tests.The procedures describe the sampling of wood in all forms, i.e., logs, chips, or sawdust.
Two sampling plans are described: A probability sampling plan which provides test units from which some property of the wood may be determined within known and controlled limits at a minimum total cost; an economic or engineered sampling plan which minimizes errors due to variations in the raw material or the quality of the lot.
