Timber structures - Strength graded structural timber with rectangular cross section - Part 2: Machine grading; additional requirements for initial type testing

This European Standard specifies requirements, additional to those in EN 14081-1, for initial type testing of machine graded structural timber with rectangular cross-sections shaped by sawing, planing or other methods, and having deviations from the target sizes corresponding to EN 336. This includes requirements for strength grading machines and test equipment for proof loading graded material, and optional requirements for control planks to test the dynamic performance of grading machines.

Holzbauwerke - Nach Festigkeit sortiertes Bauholz für tragende Zwecke mit rechteckigem Querschnitt - Teil 2: Maschinelle Sortierung, zusätzliche Anforderungen an die Erstprüfung

Diese Europäische Norm legt Anforderungen an die Erstprüfung für maschinell sortiertes Bauholz für tragende Zwecke mit rechteckigem Querschnitt fest, welches durch Sägen, Hobeln oder andere Produktionsverfahren hergestellt wurde und die zulässigen Maßabweichungen nach EN 336 einhält. Die Anforderungen gelten neben den in EN 14081-1 angegebenen. Anforderungen an Maschinen, die nach Festigkeit sortieren, und an Prüfeinrichtungen für die Prüfung von Bauholz, das durch Prüfbelastung sortiert wurde, sowie Sonderanforderungen an Referenzbohlen zur Prüfung des dynamischen Leistungsvermögens von Sortiermaschinen sind ebenfalls enthalten.

Structures en bois - Bois de structure de section rectangulaire classé selon la résistance - Partie 2: Classement mécanique - Exigences supplémentaires concernant les essais de type initiaux

La présente Norme européenne spécifie les exigences, en complément des exigences établies dans l’EN 14081-1, concernant les essais de type initiaux du bois de structure de sections rectangulaires classé par machine et profilé par sciage, rabotage ou d’autres méthodes, et dont les dimensions s’écartent des dimensions cibles correspondant à l’EN 336. Ceci comprend les exigences concernant les machines de classement de la résistance et le matériel d’essai pour les matériaux classés en fonction de leur charge d’épreuve, ainsi que les exigences facultatives concernant les planches de contrôle destinées à vérifier la performance dynamique des machines de classement.
