Modelling the Material Resistance of Wood—Part 3: Relative Resistance in above- and in-Ground Situations—Results of a Global Survey

Durability-based designs with timber require reliable information about the wood properties and how they affect its performance under variable exposure conditions. This study aimed at utilizing a material resistance model (Part 2 of this publication) based on dose–response approach for predicting relative decay rates in above-ground situations. Laboratory field test data were, first time, surveyed globally used to determine material-specific dose values, which were correlated rates. In addition, laboratory indicators adapt in-ground exposure. The relationship between in- above-ground, predictive power predict such rates, method implementing both service life prediction tool, established 195 hardwoods, 29 softwoods, 19 modified timbers, 41 preservative-treated timbers.
