Durability of wood and wood-based products - Use classes: definitions, application to solid wood and wood-based products

This European Standard is applicable to solid wood and wood-based products.
This European Standard defines five use classes that represent different service situations to which wood and wood-based products can be exposed. This standard also indicates the biological agents relevant to each situation.
A use class is not a performance class and does not give guidance for how long wood and wood-based product will last in service.

Dauerhaftigkeit von Holz und Holzprodukten - Gebrauchsklassen: Definitionen, Anwendung bei Vollholz und Holzprodukten

Diese Europäische Norm gilt für Vollholz und Holzprodukte.
Diese Europäische Norm legt fünf Gebrauchsklassen fest, die die verschiedenen Nutzungssituationen repräsentieren, denen Holz und Holzprodukte ausgesetzt sein können. Diese Norm enthält zudem Aussagen, welche Organismen unter den jeweiligen Bedingungen von Bedeutung sind.
Eine Gebrauchsklasse ist keine Leistungsklasse und beschreibt nicht die zu erwartende Gebrauchsdauer des Holzes und der Holzprodukte.

Durabilité du bois et des matériaux à base de bois - Classes d'emploi: définitions, application au bois massif et aux matériaux à base de bois

Cette Norme européenne est applicable aux produits en bois et à base de bois.
Cette Norme européenne définit cinq classes d’emploi qui correspondent aux différentes situations en service auxquelles peuvent être exposés le bois et les matériaux à base de bois. Cette Norme indique également les agents biologiques correspondant à chaque situation.
Une classe d’emploi n’est pas une classe de performance et ne donne pas d’indication concernant la durée de vie du bois en service des produits en bois et à base de bois.

Trajnost lesa in lesnih proizvodov - Razredi uporabe: definicije, uporaba pri masivnem lesu in lesnih ploščah

Ta evropski standard se uporablja za masivni les in lesne proizvode. Ta evropski standard določa pet razredov uporabe, ki ustrezajo različnim razmeram, kjer se lahko uporabljajo les in lesni proizvodi. V standardu so opisani tudi biološki dejavniki, značilni za posamezen razred uporabe. Razred uporabe ni razred učinkovitosti in ne podaja smernic glede življenjske dobe lesa in lesnih proizvodov na določenem mestu uporabe.
