Fluid accessibility of various structural components of 15 hardwoods belonging to different treatability classes was studied by using water-soluble and organic solvent stains. Penetration was found to vary even among the species categorized under the same treatability class indicating large-scale variation within the existing treatability classes. A quantitative estimation of this behavior was obtained in the form of a penetration index. This approach indicates that treatability class needs a change for 5 of the 15 species studied.
