Adhesives for load-bearing timber structures - Test methods - Part 1: Determination of longitudinal tensile shear strength
This European Standard specifies a method for determining the shear strength of adhesive bonds in close contact glue line and thick glue line.
It is suitable for the following applications:
a) for assessing the compliance of adhesives with EN 301, EN 15425 and prEN 16254;
b) for assessing the suitability and quality of adhesives for load-bearing timber structures.
This test is intended primarily to obtain performance data for the classification of adhesives for load-bearing timber structures according to their suitability for use in defined climatic environments. This method is not intended for use to provide for structural design, and does not necessarily represent the performance of the bonded member in service.
Klebstoffe für tragende Holzbauteile - Prüfverfahren - Teil 1: Bestimmung der Längszugscherfestigkeit
Dieser Teil von EN 302 legt ein Verfahren zur Bestimmung der Scherfestigkeit von Klebstoffverbindungen in dünnen und dicken Klebstofffugen fest.
Er gilt für folgende Anwendungen:
a) zur Beurteilung der Übereinstimmung von Klebstoffen mit EN 301 und EN 15425;
b) zur Beurteilung der Eignung und Qualität von Klebstoffen für tragende Holzbauteile.
Diese Prüfung ist hauptsächlich dafür vorgesehen, Leistungsdaten für die Klassifizierung von Klebstoffen für tragende Holzbauteile entsprechend ihrer Eignung zur Verwendung in festgelegten klimatischen Umgebungen zu erhalten.
Dieses Verfahren ist nicht dafür vorgesehen, Konstruktionsdaten zu ermitteln und gibt nicht zwangsläufig die Leistungsfähigkeit des geklebten Bauteils im Gebrauch wieder.

La présente partie de l’EN 302 décrit une méthode de détermination de la résistance au cisaillement des adhésifs en joint mince et en joint épais.
Elle concerne les applications suivantes :
a) évaluation de la conformité des adhésifs à l’EN 301 et à l’EN 15425 ;
b) évaluation de l’adéquation et de la qualité des adhésifs pour les structures portantes en bois.
Le présent essai est principalement destiné à obtenir des données de performances en vue de la classification des adhésifs pour les structures portantes en bois en fonction de leur aptitude à l’utilisation dans des environnements climatiques définis.
La présente méthode n’est pas destinée à fournir des données relatives au dimensionnement des structures et ne représente pas nécessairement les performances de l’élément collé dans son application.
Lepila za nosilne lesene konstrukcije - Preskusne metode - 1. del: Ugotavljanje vzdolžne natezne strižne obremenitve
Ta evropski standard določa metodo za ugotavljanje strižne obremenitve strjenega lepila pri zelo tankem in pri debelem sloju lepljenega stika.
Metoda se uporablja:
a) za oceno skladnosti lepil s standardi EN 301, EN 15425 in prEN 16254;
b) za oceno ustreznosti in kakovosti lepil za nosilne lesene konstrukcije.
Ta preskus je namenjen zlasti pridobivanju podatkov o lastnostih za razvrstitev lepil za nosilne lesene konstrukcije glede na njihovo ustreznost za uporabo v opredeljenih podnebnih okoljih. Ta metoda ni namenjena za zagotavljanje podatkov za konstrukcijsko zasnovo, pri čemer ne predstavlja nujno lastnosti zlepljenega elementa v uporabi.
