Diese Europäische Norm legt die Leistungsanforderungen für tragende Holzwerkstoffe in Fußböden, Dächern und Wänden fest, die auf tragenden Lagerhölzern und Rippen für Unterböden, Wandbeplanungen und Dachschalungen für Wohn- und Geschäftszwecke (Endanwendungen A, B, H und I nach EN 1991-1-1) befestigt sind und beschreibt ein Nachweis-Verfahren für die Übereinstimmung durch Typprüfung:
- Punktbelastung für Stanzscherung;
- Prüfung durch weichen Stoß.
Enthalten ist darüber hinaus ein Berechnungsverfahren für weiche Bedeckungen, die auf Dächern oder Fußböden verlegt sein können.
ANMERKUNG Der weiche Stoß, der Sicherheitsfragen während des Baus und Betriebs anspricht, wird weder in EN 1991-1 noch in EN 1995-1-1 definiert.
Flächenlasten nach EN 1991-1-1 werden in dieser Norm nicht berücksichtigt; tragende Platten können jedoch nach EN 1995-1-1, EN 789, EN 14358 (und EN 1058) sowie EN 12369 (Teil 1, Teil 2 und Teil 3) berechnet werden.
Im Hinblick auf Fußböden und Dächer gilt die vorliegende Norm nicht für die Endanwendung C, D und E (siehe EN 1991-1-1).

La présente norme ne prend pas en compte les charges uniformément réparties selon l’EN 1991-1-1, mais on peut calculer les panneaux travaillants selon les EN 1995-1-1, EN 789, EN 14358 (et EN 1058) et EN 12369 (parties 1, 2 et 3).
En ce qui concerne les planchers et toitures, la présente norme ne s’applique pas aux usages C, D et E (voir l’EN 1991-1-1).

EN 12871:2010 (E) 4 Foreword This document (EN 12871:2010) has been prepared by Technical Committee CEN/TC 112 “Wood-based panels”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2010, and conflicting national standards shall be withdrawn at the latest by September 2010. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12871:2001. Compared to EN 12871:2001 the following changes have been made: a) the publication of EUROCODE 1 (EN 1991-1-1) and EUROCODE 5 (EN 1995-1-1) after EN 12871 made the latter obsolete with regard to coefficients, loads and testing apparatus; b) the serviceability limit, for which EN 12871 sets specifications, is missing in EN 1195. If test reports in accordance with that standard do not allow to determine this factor, this revised version provides a means to derive it; c) where no national regulations exist, specifications are proposed for panel deflection under concentrated loading; d) the additional requirements for roofing covered with membrane has been upgraded with regard to the shrinkage of the supporting panels; e) the exploitation of the results has been updated to take into account the revision of EN 14358.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. SIST EN 12871:2010
EN 12871:2010 (E) 5 Introduction This revision incorporates modifications introduced since the publication of the previous version in European Standards, especially EN 1995-1-1 (EUROCODE 5) and wood-based panels harmonised standard: EN 13986. To assess the performances of completed structures incorporating wood-based panels, two complementary procedures are available. The first approach is to design the structure by calculation in accordance with EN 1995-1-1, using structural characteristic values, tabled in EN 12369 (all parts) or derived according to EN 1058 and EN 789. This method can be applied to any structure.
However, these standards provide no evaluation for concentrated loads or impact loads. Non-standard calculation methods for these properties may not lead to an optimised design in terms of performance.
The second approach is to design the structure by type testing in order to satisfy the requirements for both impact and concentrated loading. This approach yields an optimised design since the results from the testing apply only to that one specific design.
This standard relates specifically to the second approach, namely, design by type testing. Thus, this standard sets out the specifications and requirements for structural floor or roof decking or wall sheathing using
wood-based panels. SIST EN 12871:2010
EN 12871:2010 (E) 6 1 Scope This European Standard specifies the performance requirements and the procedure for demonstrating compliance, through type testing, of load-bearing wood-based panels fitted on: a) structural joists for decking: − in flooring applications in categories of use A, B, C and D; − in roof applications in categories of use H and I; for which type testing involves: − punching shear under concentrated loading; − vertically dropped soft body impact; b) studs for walling application for which type testing involves: − racking behaviour; − pendular soft body impact. This European Standard also provides a calculation method related to soft overlays that may be installed on roofs or floors with uniform loading. NOTE Soft body impact, addressing safety matters both during construction and in service, is defined in EN 1990 and EN 1991-1 (all parts). Annex A (normative) lists the contact areas of the loading heads that may be used for concentrated loading. Annex B (informative) provides examples for a decking application in a floor and a roof. 2 Normative references The following referenced documents are indispensable for the application of this document.
