Rezumat:
         Lucrarea prezinta cercetari experimentale privind durabilitatea lemnului, prin teste de laborator in contact cu solul conform unei metode adaptate dupa SR EN 807:2003. Speciile testate au fost brad (Abies alba Mill.), molid (Picea abies ), pin silvestru (Pinus sylvestris L.), larice (Larix decidua Mill.), stejar (Quercus robur L.), fag (Fagus sylvatica L.), salcam (Robinia Pseudacacia) si eucalipt (Eucaliptus globulus L.). In incercari au fost utilizate epruvete martor netratate si tratate prin impregnare cu Romalit N. Sunt prezentate o serie de rezultate preliminare macroscopice si microscopice. Rezultatele evidentiaza colonizarea biologica diferentiata a probelor investigate, demonstrand diferentele de durabilitate functie de specie si tratament. Testul este in derulare urmand sa se faca evaluarea finala in perioada urmatoare.
