Dans le cadre de la mise en place du marquage CE pour les bois destin\u00e9s \u00e0 un usage en structure, les scieries doivent proc\u00e9der \u00e0 un classement de leurs bois en fonction de leur r\u00e9sistance m\u00e9canique, selon les normes en vigueur. Actuellement, la quasi-totalit\u00e9 de ces classements se fait par m\u00e9thode visuelle, selon la norme NF B 52 001. Or, la prise en compte des crit\u00e8res de classement tels qu\u0092ils sont d\u00e9finis dans cette norme pour les pins (et notamment le pin sylvestre) entra\u00eene un d\u00e9classement important des pi\u00e8ces de bois et risque de limiter l\u0092’utilisation de cette essence pour la construction. Contrairement aux autres essences (douglas, sapin, \u00e9pic\u00e9a), il n’\u0092existe pas, pour les pins, de distinction entre petites et grosses sections pour les crit\u00e8res de classement structure. A la demande des scieurs sp\u00e9cialis\u00e9s dans la valorisation de cette essence en bois de structure, Auvergne Promobois, en partenariat avec le FCBA, engage une action collective pour la requalification des grosses sections de pin sylvestre. Cette requalification permettra notamment de revoir les crit\u00e8res relatifs \u00e0 la taille des noe\u009cuds de rive et la largeur des cernes d’\u0092accroissement. Une fois cette \u00e9tude termin\u00e9e et valid\u00e9e par les professionnels, une demande de modification de la norme NF B 52 001 sera d\u00e9pos\u00e9e aupr\u00e8s de la Commission de normalisation (demande d’\u0092amendement du tableau des pins de la norme NF B 52 001 avec int\u00e9gration des crit\u00e8res sp\u00e9cifiques au tri pour la r\u00e9sistance des grosses sections). Cette action b\u00e9n\u00e9ficie du soutien financier de France Bois For\u00eat, de la DRAAF Auvergne, de la R\u00e9gion Auvergne et du Comit\u00e9 d\u0092’expansion \u00e9conomique de Haute-Loire. Le syndicat des scieurs de Haute-Loire et les entreprises Piveteau Bois, Barillet, Comptoir des Bois Sabbe et Mandray sont partenaires de cette \u00e9tude.\u000b\u000bwww.auvergne-promobois.com<\/span><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
