An update on durability of New Zealand grown timber

IRG/WP 15-10851

D Page, T Singh

Classification and predication of in-service performances of naturally durable timber is much more difficult than preservative treated timber due to the variability of wood properties within and between trees of the same species and the variable nature of the hazard to which the timber will be exposed. A combination of field test and in-service testing has been used to classify the suitability of New Zealand locally grown timber for various end-uses and to show that they are a suitable substitute for preservative treated timber. Suggested uses of the species, their suitability to meet the requirements of NZS 3602:2003 and likely limitations are discussed.
