(Main)Wood-based panels - Determination of performance characteristics for load bearing panels for use in floors, roofs and walls
Wood-based panels - Determination of performance characteristics for load bearing panels for use in floors, roofs and walls
This European Standard specifies:
- concentrated load test and assessment methods for floor and roof decking;
- soft body impact assessment methods and classification system for floors, roofs and walls.
This European Standard does not include racking testing or uniformly distributed loads as these are covered by testing according to EN 594 or calculation according to EN 1995-1-1 respectively.
This European Standard specifies the procedure for determining the performance characteristics through type testing, of load-bearing wood-based panels fitted on:
a) structural joists for decking:
1) in flooring applications in load categories A, B, C and D;
2) in roof applications in load categories H and I;
for which type testing involves:
i) punching shear under concentrated loading;
ii) vertical soft body impact;
b) studs for walling application for which type testing involves:
1) pendular soft body impact.
Annex A (normative) lists modifications to EN 1195, particularly the contact area of the loading head that may be used for concentrated loading.
Annex B (informative) provides proposals for national performance requirements.
Annex C (informative) provides examples for a decking application in a floor and a roof.
Holzwerkstoffe - Bestimmung der Leistungseigenschaften für tragende Platten zur Verwendung in Fußböden, Wänden und Dächern
Diese Europäische Norm legt Folgendes fest:
• Prüfung von Punktlasten und Bewertungsverfahren für tragenden Unterboden und tragende Dachschalung;
• Bewertungsverfahren für die Prüfung durch weichen Stoß sowie Klassifizierungssysteme für Fußböden, Dächer und Wände.
Diese Europäische Norm enthält keine Prüfungen von Wandscheiben oder Flächenlasten, da diese entsprechend jeweils nach Prüfung in EN 594 oder Berechnung nach EN 1995-1-1 bestimmt werden können.
Diese Europäische Norm legt das Verfahren für die Bestimmung der Leistungseigenschaften durch Bauart-prüfung von tragenden Platten aus Holzwerkstoffen fest, die folgendermaßen befestigt sind:
a) an tragenden Lagerhölzern:
1) in Unterbodensystemen der Lastkategorien A, B, C und D;
2) in Dachsystemen der Lastkategorien H und I;
für die die Bauartprüfung Folgendes umfasst:
i) Stanzscherfestigkeit bei Punktbelastung;
ii) senkrecht erfolgender weicher Stoß;
b) Rippen für Wandsysteme, für die die Bauartprüfung Folgendes umfasst:
1) pendelnder weicher Stoß.
Anhang A (normativ) führt die Änderungen aus EN 1195 auf, insbesondere die Kontaktflächen der Prüfstempel, die zur Punktbelastung verwendet werden dürfen.
Anhang B (informativ) enthält Vorschläge für nationale Leistungsanforderungen.
Anhang C (informativ) enthält Beispiele für Unterboden- und Dachschalungssysteme.
Panneaux à base de bois - Détermination des caractéristiques de performance des panneaux travaillants utilisés en planchers, toitures et murs
La présente norme européenne spécifie :
• un essai de charge concentrée et des méthodes d'évaluation pour les platelages de planchers et de toitures ;
• des méthodes d'évaluation de choc d'un corps mou et un système de classification pour les planchers, toitures et murs.
La présente norme européenne ne contient pas d'essais relatifs au contreventement ni de charges uniformément réparties car ils sont couverts respectivement par des essais conformément à l'EN 594 ou des calculs conformément à l'EN 1995-1-1.
La présente norme européenne spécifie le mode opératoire permettant de déterminer les caractéristiques de performance, par des essais de type, des panneaux travaillants à base de bois placés sur :
a) solives pour platelage :
1) pour des applications en planchers dans les catégories de charge A, B, C et D ;
2) pour des applications en toitures dans les catégories de charge H et I ;
pour lesquelles l'essai de type implique :
i) le cisaillement par poinçonnement sous charge concentrée ;
ii) le choc par chute verticale d'un corps mou ;
b) poteaux pour application en murs pour lesquels l'essai de type implique :
1) le choc pendulaire d'un corps mou.
L'Annexe A (normative) donne une liste des modifications par rapport à l'EN 1195, notamment la zone de contact de la tête d'application de la charge qui peut être utilisée pour la charge concentrée.
L'Annexe B (informative) propose des exigences nationales de performance.
L'Annexe C (informative) fournit des exemples d'application de platelage en planchers et toitures.
Lesne plošče - Lastnosti in zahteve za nosilne plošče, ki se uporabljajo za pode, stene in strehe
Ta evropski standard določa: – zgoščen preizkus obremenitve in metode ocenjevanja za pode in strešne kritine; – metode ocenjevanja z udarcem z mehkim telesom in sistemi klasifikacije podov, streh in sten. Ta evropski standard ne vključuje preizkusov z natezanjem ali enakomerno razporejenimi bremeni, ker te pokriva preskušanje v skladu s standardom EN 594 ali računanje v skladu s standardom EN 1995-1-1. Ta evropski standard navaja postopke za ugotavljanje značilnosti nosilnih plošč na osnovi lesa s tipskim preskušanjem, nameščene na: a) strukturne nosilce za pode: 1) preizkusi tal pri kategorijah bremen A, B, C in D; 2) preizkusi streh pri kategorijah bremen H in I; za katere tipsko preskušanje vključuje: i) strig pod zgoščeno obremenitvijo; ii) vertikalen udarec z mehkim telesom; b) vijaki za namestitev v fasado, za katere tipsko preskušanje vključuje: 1) nihajni udarec z mehkim telesom.
