It lists methods in a standardized form followed by additional detailed interpretive information. This document also includes necessary preparations of structural timber prior to this kind of treatment. It gives guidance on how to calculate necessary retentions for filling pre-drilled holes or for pressure impregnation from test results obtained from surface applications (e.g. EN 1390).
