Adhesives for load-bearing timber structures - Test methods - Part 2: Determination of resistance to delamination

This European Standard specifies a method for determining the resistance to delamination in glue lines.
It is suitable for the following applications:
a)   for assessing the compliance of adhesives with EN 301, EN 15425 and EN 16254;
b)   for assessing the suitability and quality of adhesives for load-bearing timber structures;
c)   for comparing the effects on the bond strength resulting from the choice of bonding conditions, from different climatic conditioning and from the treatment of the test pieces before and after bonding.
This test is not applicable for modified and stabilized wood with strongly reduced swelling and shrinkage properties, such as acetylated wood, heat-treated wood and polymer impregnated wood.
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 to provide data for structural design, and does not necessarily represent the performance of the bonded member in service.

Klebstoffe für tragende Holzbauteile - Prüfverfahren - Teil 2: Bestimmung der Delaminierungsbeständigkeit

Diese Europäische Norm legt ein Verfahren zur Bestimmung der Beständigkeit von Klebstoffverbindungen gegen Delaminierung fest.
Sie ist für folgende Anwendungsfälle geeignet:
a)   zur Beurteilung der Übereinstimmung von Klebstoffen mit EN 301, EN 15425 und EN 16254;
b)   zur Beurteilung der Eignung und Qualität von Klebstoffen für tragende Holzbauteile;
c)   zum Vergleich der Auswirkungen der gewählten Verklebungsbedingungen, von verschiedenen klimati¬schen Beanspruchungen und von der Behandlung der Prüfkörper vor und nach der Verklebung auf die Klebfestigkeit.
Diese Prüfung gilt nicht für modifiziertes und vergütetes Holz mit stark verringerten Quellungs- und Schwin-dungseigenschaften, wie beispielsweise acetyliertes Holz, wärmebehandeltes Holz und polymerimprägniertes Holz.
Diese Prüfung dient hauptsächlich der Bestimmung von Leistungswerten zur Klassifizierung von Klebstoffen für tragende Holzbauteile entsprechend ihrer Eignung zum Einsatz unter festgelegten klimatischen Bedin¬gungen.
Dieses Verfahren ist nicht dafür vorgesehen, Bemessungswerte bereitzustellen und gibt nicht zwangsläufig die Leistungsfähigkeit des verklebten Bauteiles im Gebrauch wieder.

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 - 2. del: Ugotavljanje odpornosti lepljenega stika proti razslojevanju (delaminaciji)

Ta evropski standard določa metodo za ugotavljanje odpornosti lepljenega stika proti razslojevanju (delaminaciji).
Metoda se uporablja:
a) za oceno skladnosti lepil s standardi EN 301, EN 15425 in EN 16254;
b) za oceno ustreznosti in kakovosti lepil za nosilne lesene konstrukcije;
c) za primerjavo vpliva na sprijemno trdnost, ki izhaja iz izbire pogojev lepljenja, različnih podnebnih danosti in obdelave preskusnih kosov pred lepljenjem in po njem.
Ta preskus se ne uporablja za obdelan in stabiliziran les, ki se bistveno manj nabreka in krči, kot so acetiliran les, toplotno obdelan les in polimerno impregniran les.
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.

EN 302-2:2017は、荷重を支える木材構造用接着剤の剥離耐性を測定するための試験方法を定めた欧州規格であり、その適用範囲は非常に広範かつ重要です。本規格は、接着剤がEN 301、EN 15425、EN 16254に準拠しているかを評価するため、また荷重を支える木材構造に適した接着剤の品質や適合性を判断するための有効な手段を提供します。 この基準の強みは、接着条件の選択や異なる気候条件、試験片の前後処理が接着強度に与える影響を比較できる点にあります。これにより、施工条件に応じた詳細な情報を得ることが可能になり、品質管理や製品開発において非常に有用です。また、接着剤の分類を目的としており、使用される気候環境に応じた接着剤の性能データを提供することができます。 ただし、注意すべき点があり、この試験は収縮や膨張の性質が大きく改善された改良・安定化された木材(アセチル化木材、熱処理木材、ポリマー浸透木材など)には適用できません。これは、特定の材料における試験の限界を示しており、実際の使用条件下での接着部材の性能を必ずしも反映するものではないことを理解する必要があります。 総じて、EN 302-2:2017は、荷重を支える木材構造用接着剤の品質評価において不可欠な標準であり、その試験方法は業界内での一致した基準の確立に寄与しています。この標準が持つ意義は、製品の信頼性を向上させ、建設業界における安全性と性能向上に直結します。

표준 EN 302-2:2017은 하중을 지탱하는 목재 구조물에 대한 접착제의 시험 방법을 규명하고 있으며, 특히 박리 저항을 결정하는 데 중점을 두고 있습니다. 이 표준의 범위는 주로 접착제의 EN 301, EN 15425 및 EN 16254 준수 여부를 평가하고, 하중을 지탱하는 목재 구조물에 적합성과 품질을 검토하는 데 적합합니다. 표준의 강점 중 하나는 목재 섬유 내 접착의 품질 및 강도에 미치는 다양한 결합 조건의 영향을 비교할 수 있는 방법을 제공한다는 점입니다. 이는 다양한 기후 조건과 시험편 처리 전후의 차이가 접착 강도에 미치는 영향을 분석하는 데 유용합니다. 이와 함께, 이 시험 방법은 하중을 지탱하는 목재 구조물에 사용될 접착제의 분류를 위한 성능 데이터를 수집하는 데 주로 사용됩니다. 그러나 이 시험 방법은 아세틸화된 목재, 열처리된 목재, 폴리머 침투 목재와 같이 변형되고 안정화된 목재에 대해서는 적용되지 않음을 명시하고 있습니다. 즉, 특정한 특성을 가진 목재에 대한 신뢰할 수 있는 데이터를 제공하지는 않습니다. 종합적으로 볼 때, EN 302-2:2017은 하중을 지탱하는 목재 구조물에서의 접착제의 성능을 평가하는 데 중요한 기준을 제공하며, 접착제의 신뢰성을 높이고 품질 관리를 촉진하는 데 핵심적인 역할을 합니다. 이는 건축 및 공학 분야에서 목재 구조의 안전성과 견고함을 보장하는 데 필수적인 표준입니다.

The standard EN 302-2:2017 provides a comprehensive method for determining the resistance to delamination in glue lines, specifically tailored for adhesives used in load-bearing timber structures. The scope of this European Standard is particularly relevant to quality assurance within the adhesive industry, as it outlines a systematic approach for assessing the compliance of adhesives with established standards such as EN 301, EN 15425, and EN 16254. One of the key strengths of this standard lies in its detailed evaluation criteria, which not only assess adhesive performance but also cover the suitability of adhesives for various timber construction applications. By allowing comparisons of bond strength influenced by different bonding conditions, climatic conditioning, and pre- and post-bonding treatments, EN 302-2:2017 equips professionals with valuable data for optimizing adhesive selection and application in load-bearing timber structures. Furthermore, the focus on obtaining performance data for classification purposes reinforces the standard's relevance in ensuring safety and integrity within timber construction. The explicit mention of the exclusion of modified and stabilized wood types, such as acetylated and heat-treated wood, further clarifies the standard's applicability and reinforces its targeted nature. It is noteworthy that while this standard provides essential insights into adhesive performance, it is designed primarily for data generation rather than structural design. This distinction ensures that users align their expectations regarding the applicability of the results within real-world scenarios, which is critical for users in the timber structure domain. In summary, EN 302-2:2017 stands out for its systematic approach to evaluating adhesive resistance to delamination, its relevance to quality assessment in load-bearing timber structures, and its ability to support the decision-making process in adhesive selection while maintaining clear boundaries regarding its intended use.
