Glued laminated timber - Performance requirements and minimum production requirements

This standard specifies requirements for the components of glued laminated timber structures members and minimum requirements for the production of such members for structural use.
This standard is applicable to products with a finished lamination thickness of not more than 45 mm.
Although most glued laminated timber is made from coniferous species this standard also applies to broad leaved species if information is available to enable them to be satisfactorily bonded.

Brettschichtholz - Leistungsanforderungen und Mindestanforderungen an die Herstellung

Diese Norm legt Anforderungen an die Bestandteile von Bauteilen aus Brettschichtholz und Mindestanforderungen an die Herstellung solcher Bauteile für tragende Zwecke fest.
Diese Norm gilt nur für Produkte mit einer fertigen Lamellendicke von höchstens 45 mm.
Obwohl Brettschichtholz meistens aus Nadelhölzern hergestellt wird, gilt diese Norm auch für Laubhölzer, sofern Angaben über die Anforderungen hinsichtlich einer zufriedenstellenden Verklebung vorliegen.

Bois lamellé collé - Exigences de performance et exigences minimales de fabrication

La présente norme définit des exigences pour les éléments de structures en bois lamellé-collé et des exigences minimales pour la fabrication de tels éléments pour usage structurel.
La norme s'applique aux produits avec une épaisseur de lamelle finie inférieure ou égale à 45 mm.
Bien que la plupart des bois lamellés collés soit réalisée à partir de conifères, la présente norme s'applique aussi aux essences feuillues si des informations sont disponibles pour leur permettre de réaliser des assemblages collés satisfaisants.

For the lamination and the end jointing, the adhesive should be chosen considering the climatic conditions in service, thetimber species, the preservative used (if any) and the production methods.NOTE 2
Such strength and durability can be achieved by a polycondensation adhesive of the phenolic or aminoplastic type asdefined in EN 301.For adhesives of other types than covered by EN 301 a bond with equivalent durability and strength shall beachieved. Special considerations shall be given to creep failure, the ability to maintain structural integrity during fireand elevated temperature and moisture conditions in ordinary service.5.4 End joints in laminationsThe characteristic bending strength fm,k obtained from flatwise bending tests of the end joints shall meet thefollowing requirement:fm,k fm,dc,kwherefm,dc,k is the declared characteristic bending strength.The flatwise bending tests shall be performed in conformity with EN 385.The characteristic bending strength shall be determined from the Log-Normal probability distribution function.5.5 Glue line integrity and strength5.5.1The requirements for glue line integrity shall be based on testing of the glue line in a full cross-sectionalspecimen, cut from the manufactured glulam member. The specimens shall be representative of the manufacture.5.5.2For structures of service class 3, delamination tests shall be made in conformity with method A of EN 391.For structures of service class 1 or 2 the testing shall be either delamination tests in conformity with method A ofEN 391 or block shear tests in conformity with EN 392.NOTE
For routine quality control the test methods specified may be substituted by the following: Delamination method A maybe substituted by delamination method B of EN 391:2001. For members to be used in service class 1 or 2 block shear tests maybe substituted by delamination method C of EN 391:2001.5.5.3Depending on the method and number of cycles the total delamination percentage of each cross-sectionalspecimen shall be less than the values given in Table 1.SIST EN 386:2002
