Plywood - Specifications
This European Standard specifies the requirements for plywood, as defined in EN 313-2, for both general purpose use (non-structural application) and structural application in dry, humid or exterior conditions. It also gives a classification system based on the bending properties. NOTE 1 This European Standard is referenced in EN 13986 for construction applications. NOTE 2 For additional guidance on application, information is provided in CEN/TS 1099. The values listed under Clause 4 relate only to product properties; they are not 'characteristic values' and are not to be used in design calculations. NOTE 3 Characteristic values (i.e. for use in design calculation according to EN 1995-1-1) are given either in EN 12369-2 which is based on the classification system given in this standard or by the manufacturer based on testing according to EN 789, EN 1058 and ENV 1156. Additional information on supplementary properties for certain applications is also given.
Sperrholz - Anforderungen
Diese Europäische Norm legt Anforderungen an Sperrholz, wie in EN 313-2 definiert, für allgemeine (nicht tragende) und tragende Zwecke zur Verwendung im Trocken , Feucht oder Außenbereich fest. Sie enthält außerdem ein Klassifizierungssystem auf der Grundlage der Biegeeigenschaften.
ANMERKUNG 1 Auf diese Norm wird in EN 13986 für Anwendungen im Bauwesen Bezug genommen.
ANMERKUNG 2 Weitere Hinweise zur Verwendung enthält CEN/TS 1099.
Die in Abschnitt 4 angegebenen Werte beziehen sich nur auf Produkteigenschaften; es sind keine charakteristischen Werte, die für konstruktive Berechnungen verwendet werden können.
ANMERKUNG 3 Solche charakteristischen Werte (d. h. für konstruktive Berechnungen in EN 1995 1 1) sind entweder in EN 12369 2 auf der Grundlage dieses „Klassifizierungssystems“ angegeben oder werden durch Prüfung nach EN 789, EN 1058 und ENV 1156 bestimmt und durch den Hersteller angegeben.
Sie enthält zusätzliche Informationen über weitere Eigenschaften für bestimmte Verwendungszwecke.
Contreplaqué - Exigences
Le présent document prescrit les exigences relatives aux panneaux contreplaqués selon l'EN 313-2, pour usage général (non utilisation en structure) et pour utilisation en structure, utilisés en milieu sec, humide ou extérieur. Elle décrit également un système de classification basé sur les propriétés en flexion.

Vezane plošče - Specifikacije
Ta evropski standard določa zahteve za vezane plošče, kot je določeno v standardu EN 313-2, ki se uporabljajo za splošne namene (nekonstrukcijska uporaba) in konstrukcijsko uporabo v suhih, vlažnih ali zunanjih pogojih. Podaja tudi sistem razvrščanja na podlagi lastnosti upogibanja. OPOMBA 1 Na ta evropski standard se sklicuje standard EN 13986 za uporabo v gradbeništvu. OPOMBA 2 Informacije o dodatnih smernicah v zvezi z uporabo so podane v standardu CEN/TS 1099. Vrednosti, naštete v točki 4, se nanašajo le na lastnosti izdelka; niso karakteristične vrednosti in se jih ne sme uporabljati v projektnih izračunih. OPOMBA 3 Karakteristične vrednosti (npr. za uporabo v projektnih izračunih v skladu s standardom EN 1995-1-1) so podane v standardu EN 12369-2, ki temelji na sistemu razvrščanja iz tega standarda, ali pa jih zagotovi proizvajalec na podlagi preskušanja v skladu s standardi EN 789, EN 1058 in ENV 1156. Podane so tudi dodatne informacije o dopolnilnih lastnostih za določene vrste uporabe.
