The influence of some surface and edge coatings on MUF glued panels made of veneers of the poplar clone I214 has been evaluated against the attack of wood decay fungi according to the test method provided by CEN TC38 now ENV 12038. The residual bonding quality has also been verified EN 314 . All specimens showed a high level of biodegradation. The best protection system seems to be the combination of treating the surface and painting the edges of the panels while the surface treatments alone were less effective. The article also points out that the test method used is not the most suitable for evaluating the biological durability of plywood considering its real use in exterior conditions. poplar plywood fungal decay biological durability protective treatment Résumé - Résistance du contreplaqué de peuplier aux dégâts dus aux champignons efficacité des traitements de protection en relation à la norme ENV 12038. Ce travail est une contribution à la connaissance du comportement du contreplaqué de peuplier face aux dégâts dus aux champignons en considérant son utilisation dans une exposition caractérisée par une forte humidité. L influence de la protection sur la surface et sur le bord des panneaux collés avec une résine MUF réalisés avec des placages déroulés provenant du clone I-214 a été .
