La degradation du bois \u00e0 cause de l’humidit\u00e8 de l’environnement.<\/strong><\/h2>\n

Il existe de multiples agents susceptibles de provoquer la d\u00e9gradation du bois.
\nOr, aussi bien pour les champignons que pour les insectes, le facteur limitant le d\u00e9veloppement<\/strong> est tr\u00e8s souvent l’humidit\u00e9<\/strong>.<\/p>\n

Il existe donc une tr\u00e8s forte corr\u00e9lation entre le milieu o\u00f9 se trouve le bois de charpente et les attaques d’agents biologiques destructeurs.<\/p>\n

Par exemple, on comprendra ais\u00e9ment que le bois conserv\u00e9 \u00e0 l’abri, en milieu ferm\u00e9 et sec<\/strong>, a une dur\u00e9e plus \u00e9tendue<\/strong> que le m\u00eame bois mis au contact du terrain humide.<\/p>\n

Le CEN<\/strong> (Comit\u00e9 Europ\u00e9en de Normalisation) a d\u00e9fini 5 classes de risque<\/strong>, dans la Norme Europ\u00e9enne EN 335, parties 1, 2, et 3,\u00a0 qui se distinguent en fonction de l’humidit\u00e9<\/strong> \u00e0 laquelle le bois est expos\u00e9 dans les diff\u00e9rentes conditions d’utilisation.<\/p>\n

Plus le risque est \u00e9lev\u00e9e<\/strong>, plus la n\u00e9cessit\u00e9 d’augmenter la r\u00e9sistance<\/strong> naturelle du bois par des traitements d’impr\u00e9gnation<\/strong> s’affirme.<\/p><\/blockquote>\n

D\u00e9finition des CLASSES DE RISQUE<\/strong><\/h3>\n
\n

Classe de risque 1<\/strong>:situation dans laquelle le bois ou le produit \u00e0 base de bois est abrit\u00e9, compl\u00e8tement prot\u00e9g\u00e9 des agents atmosph\u00e9riques et non expos\u00e9 \u00e0 l’humidit\u00e9.<\/p>\n

Classe de risque 2<\/strong>: situation dans laquelle le bois ou le produit \u00e0 base de bois est abrit\u00e9 et compl\u00e8tement prot\u00e9g\u00e9 des agents atmosph\u00e9riques, mais o\u00f9 une humidit\u00e9 ambiante \u00e9lev\u00e9e peut entra\u00eener une humidification occasionnelle, mais non persistante.<\/p>\n

Classe de risque 3<\/strong>: situation dans laquelle le bois ou le produit \u00e0 base de bois n’est pas abrit\u00e9 et ne se trouve pas au contact du terrain. Il se trouve expos\u00e9 constamment aux agents atmosph\u00e9riques ou, m\u00eame en \u00e9tant prot\u00e9g\u00e9 contre ces derniers, il subit une humidification fr\u00e9quente.<\/p>\n

Classe de risque 4<\/strong>: situation dans laquelle le bois ou le produit \u00e0 base de bois se trouve en contact avec le terrain ou l’eau douce et est donc expos\u00e9 de fa\u00e7on permanente \u00e0 l’humidification.<\/p>\n

Classe de risque 5<\/strong>: situation dans laquelle le bois ou le produit \u00e0 base de bois est expos\u00e9 de fa\u00e7on permanente \u00e0 l’eau sal\u00e9e.<\/p>\n
