Structural finger jointed solid timber - Performance requirements and minimum production requirements
This European Standard sets out provisions regarding the performance characteristics for structural finger jointed timber with rectangular cross section for use in buildings and bridges.
The use of structural finger jointed timber may be limited to certain service classes in some member states.
It also lays down minimum production provisions and procedures for Assessment and Verification of Constancy of Performance for structural finger jointed timber.
This European Standard is applicable to structural finger jointed timber made of coniferous timber species listed in this standard or poplar.
Although it may be possible to produce structural finger jointed timber made from specific broadleaf species based on some provisions of this European Standard, this standard is not applicable to these products.
This European Standard is only applicable to finger joints between timber sections of the same species.
This European Standard does not cover impressed (die-formed) finger joints.
This European Standard covers structural finger jointed timber untreated or treated against biological attack. Structural finger jointed timber treated with fire retardants is not covered.
Keilgezinktes Vollholz für tragende Zwecke - Leistungsanforderungen und Mindestanforderungen an die Herstellung
Diese Europäische Norm enthält Festlegungen hinsichtlich der Leistungsmerkmale von keilgezinktem Vollholz für tragende Zwecke mit rechteckigem Querschnitt zur Verwendung im Hoch- und Brückenbau.
ANMERKUNG Die Verwendung von keilgezinktem Vollholz für tragende Zwecke kann in einigen Mitgliedstaaten auf bestimmte Nutzungsklassen beschränkt sein.

Diese Europäische Norm gilt für keilgezinktes Vollholz für tragende Zwecke aus Nadelholzarten, die in dieser Norm aufgeführt sind, oder Pappelholz.
Obwohl auf der Grundlage einiger Festlegungen dieser Europäischen Norm keilgezinktes Vollholz für tragende Zwecke aus besonderen Laubholzarten hergestellt werden könnte, gilt diese Norm nicht für diese Produkte.
Diese Europäische Norm gilt nur für keilgezinktes Vollholz für tragende Zwecke derselben Holzart.
Keilzinkenverbindungen, die mit Pressverformung („die-formed“) hergestellt werden, sind in dieser Europäischen Norm nicht berücksichtigt.
Diese Europäische Norm gilt für unbehandeltes oder zum Schutz gegen biologischen Befall behandeltes keilgezinktes Vollholz für tragende Zwecke. Mit Flammschutzmitteln behandeltes keilgezinktes Vollholz für tragende Zwecke ist nicht Gegenstand dieser Norm.
Bois massif de structure à entures multiples - Exigences de performances et exigences minimales de fabrication
La présente Norme Européenne spécifie les exigences concernant les caractéristiques de performance du bois de structure avec aboutages à entures multiples de section rectangulaire destiné à être utilisé dans les bâtiments et les ponts.
Dans certains États Membres, l'utilisation de bois de structure avec aboutages à entures multiples peut être limitée à certaines classes de service.
Elle spécifie également les exigences minimales relatives à la fabrication ainsi que les procédures d'évaluation et de vérification de la constance des performances du bois de structure avec aboutages à entures multiples.
La présente Norme Européenne s'applique au bois de structure avec aboutages à entures multiples fabriqué à partir des essences de bois de résineux énumérées dans la présente Norme ou de peuplier.
Bien qu'il puisse être possible de fabriquer du bois de structure avec aboutages à entures multiples à partir d'essences de bois feuillus spécifiques en se basant sur certaines exigences de la présente Norme Européenne, celle-ci ne s'applique pas à ces produits.
La présente Norme Européenne s'applique uniquement aux aboutages à entures multiples entre des profilés en bois de même essence.
La présente Norme Européenne ne traite pas des aboutages emboutis.
La présente Norme Européenne s'applique au bois de structure avec aboutages à entures multiples non traité ou traité contre les attaques biologiques. Le bois de structure avec aboutages à entures multiples traité par des produits ignifuges n'est pas couvert.
Konstrukcijski zobato spojen masivni les - Zahteve za uporabo in minimalne zahteve za proizvodnjo
Standard EN 15497 podaja določbe v zvezi z zahtevami za uporabo konstrukcijskega zobato spojenega lesa s pravokotnim prečnim prerezom pri gradnji stavb in mostov. Uporaba konstrukcijskega zobato spojenega lesa je v nekaterih državah članicah morda omejena na določene razrede storitev. Standard prav tako podaja minimalne določbe za proizvodnjo in postopke za ocenjevanje in preverjanje nespremenljivosti lastnosti konstrukcijskega zobato spojenega lesa. Ta evropski standard velja za konstrukcijski zobato spojeni les, izdelan iz iglavcev, ki so navedeni v tem standardu, ali topolovine. Čeprav je na podlagi nekaterih določb tega evropskega standarda izdelava konstrukcijskega zobato spojenega lesa iz določenih listavcev mogoča, ta standard ne velja za te izdelke. Ta evropski standard velja samo za zobate spoje med lesenimi elementi iz iste vrste lesa. Ta standard ne zajema tlačno litih zobatih spojev. Ta evropski standard zajema zaščiten in nezaščiten konstrukcijski zobato spojeni les pred biološkimi dejavniki. Konstrukcijski zobato spojeni les, ki je obdelan z zaščitnimi sredstvi proti ognju, ni zajet.

Class as provided for in Table 1 of the Annex to Decision 2000/147/EC.
When reaction to Fire is determined by testing the product shall be tested according to EN 13823 (SBI test) and mounted and fixed in accordance with the following: — the whole area of both wings in the SBI apparatus shall be covered with pieces of structural flinger jointed timber mounted edge to edge (butt jointed), without jointing or bonding and orientated horizontally or vertically; — supported by battens of the product concerned of a size minimum (40 × 80) mm, fixed to the test backing boards at 400 mm to 600 mm centres horizontally or vertically (perpendicular to the orientation of the product pieces), so that the resulting spacing between backing board and product is 80 mm; see also Figure 3. NOTE Test results are valid for finger jointed structural timber having at least the density and the minimum overall thickness of the specimens tested.
