Adaptación de la madera de Eucalyptus globulus a la normativa europea de durabilidad natural

Abstract

La madera de Eucalyptus globulus en algunos países como Australia es recomendada para situaciones de riesgo de ataque de organismos xilófagos por su elevada durabilidad. En Galicia esta madera ha sido utilizada desde hace muchas décadas en estructuras y carpinterías, que aún hoy perduran. Sin embargo, la norma europea EN-350-2 encuadra la especie E. globulus en la peor categoría de durabilidad natural, situación que no se corresponde con la realidad. El objetivo de este proyecto es constatar la durabilidad de esta especie frente a hongos de pudrición e insectos xilófagos y modificar en consecuencia la clase de durabilidad asignada en la norma europea. Con este fin se están realizando los correspondientes ensayos frente a hongos e insectos xilófagos, tanto en laboratorio como en campo. Los resultados que se han obtenido con los hongos de pudrición fibrosa y pudrición blanda indican que, efectivamente, el duramen es durable (clase 2), mientras que la albura no es durable (clase 4) y la madera juvenil es medianamente durable (clase 3). De este modo, se confirma la elevada durabilidad del duramen de eucalipto, a la espera de finalizar los ensayos en curso y obtener los resultados finales.__________________________In some countries as Australia the wood of Eucalyptus globulus is recommended for its high durability in risk situations where attack by organisms is likely to occur. In Galicia this species has been utilised since many decades for timber structures, which are still in service. But the European Standard EN-350-2 qualifies Eucalyptus globulus with the worst category of natural durability, situation that does not correspond with the reality. The objetive of this project is to determine the durability of the species against wood decay fungi and wood boring insects and to accordingly classify E. globulus in the mentioned standard. To achieve this objective laboratory and field tests against fungi and insect attack are carried out. The preliminary results of the laboratory tests with white and soft rot indicate that the heartwood is durable (class 2), sapwood is not durable (class 4) and juvenil wood is moderately durable (class 3). These results confirm the high durability of the heartwood of this species, pending the end of the remaining tests.
