(Main)Particleboards - Specifications
Particleboards - Specifications
This European Standard specifies the requirements for flat-pressed or calendar-pressed unfaced particleboards as defined in EN 309.
NOTE 1 This standard is called up in EN 13986 for construction applications. Products specified in this standard are referred to in EN 13986 as resin-bonded particleboards.
The values listed in this standard relate to product properties, but they are not characteristic values to be used in design calculations.
NOTE 2 Such characteristic values (e.g. for use in design calculation in EN 1995-1-1) are given either in EN 12369-1 or derived by testing according to EN 789, EN 1058 and ENV 1156.
Additional information on supplementary properties for certain applications is also given.
NOTE 3 Particleboards in accordance with this standard may be referred to as P1 to P7-boards.
Boards of type P4 to P7 are intended for use in design and construction of load-bearing or stiffening building elements, e.g. walls, flooring, roofing and I-beams (see EN 1995-1-1 and/or performance standards).
This standard does not apply to extruded particleboards and flaxboards, which are standardised in EN 14755 and EN 15197 respectively.
Spanplatten - Anforderungen
Diese Europäische Norm legt Anforderungen an flach- oder kalandergepresste, unbeschichtete Spanplatten, wie in EN 309 definiert, fest. ANMERKUNG 1 Auf diese Norm wird in EN 13986 für Anwendungen im Bauwesen Bezug genommen. Die in dieser Norm geregelten Produkte werden in EN 13986 als kunstharzgebundene Spanplatten bezeichnet. Die in dieser Norm angegebenen Werte beziehen sich auf Produkteigenschaften; es sind keine charakteristischen Werte, die für konstruktive Berechnungen verwendet werden können. ANMERKUNG 2 Solche charakteristischen Werte (z. B. für konstruktive Berechnungen in EN 1995-1-1) sind entweder in EN 12369-1 angegeben oder werden durch Prüfung nach EN 789, EN 1058 und ENV 1156 ermittelt. Sie enthält zusätzliche Informationen über weitere Eigenschaften für bestimmte Verwendungszwecke. ANMERKUNG 3 Spanplatten nach dieser Norm können als P1- bis P7-Platten bezeichnet werden. Die Plattentypen P4 bis P7 sind zur Ausführung von tragenden oder aussteifenden Bauteilen vorgesehen, z. B. Wand-, Fußboden-, Dachkonstruktionen oder I-Trägern (siehe EN 1995-1-1 und/oder Leistungsnormen). Diese Norm gilt nicht für Strangpressplatten und Flachsspanplatten. Hierfür gelten EN 14755 bzw. EN 15197.
Panneaux de particules - Exigences
La présente Norme européenne prescrit les exigences pour les panneaux de particules non revêtus, pressés
à plat ou par cylindre tels que définis dans l’EN 309.
NOTE 1 La présente norme est référencée dans la norme EN 13986 pour les applications dans la construction. Les
produits spécifiés dans la présente norme sont référencés dans l’EN 13986 comme panneaux de particules liées à la
résine.
Les valeurs données dans la présente norme concernent les caractéristiques du produit mais ne sont pas les
valeurs caractéristiques à utiliser dans les calculs de conception
NOTE 2 De telles valeurs caractéristiques (par exemple pour des calculs de conception selon EN 1995-1-1) sont soit
données dans la norme EN 12369-1 soit obtenues à partir d’essais selon les normes EN 789, EN 1058 et ENV 1156.
Des informations supplémentaires sur des caractéristiques complémentaires relatives à certaines applications
sont également fournies.
NOTE 3 Les panneaux de particules conformes à cette norme peuvent être désignés comme panneaux P1 à P7. Les
panneaux de type P4 à P7 sont destinés à être utilisés dans la conception et la construction d’éléments de
bâtiment travaillants ou raidisseurs, par exemple en mur, plancher, toiture ou poutre en I (voir EN 1995-1-1
et/ou les normes de performances).
La présente norme ne s’applique pas aux panneaux extrudés et panneaux de lin qui sont, respectivement
normalisés dans les normes EN 14755 et EN 15197.
Iverne plošče - Specifikacije
Ta evropski standard določa zahteve za plosko stisnjene iverne plošče oziroma po opredeljenem postopku stisnjene neobdelane iverne plošče, kot je opredeljeno v EN 309. Vrednosti, navedene v tem standardu, se nanašajo na lastnosti proizvodov, vendar niso značilne vrednosti, ki bi jih uporabili v izračunih pri načrtovanju. Podane so tudi dodatne informacije o dopolnilnih lastnostih za nekatere vrste uporabe. Ta standard ne velja za ekstrudirane iverne plošče in lanene plošče, ki so standardizirane v EN 14755 in EN 15197.
