Adhesives for load-bearing timber structures - Test methods - Part 3: Determination of the effect of acid damage to wood fibres by temperature and humidity cycling on the transverse tensile strength
This Part of EN 302 describes a method of determining the effect on bond strength of damage to wood fibres caused by the action of acids from the adhesive during climatic cycling. It is suitable for the following applications: a) for assessing the compliance of adhesives with EN 301; b) for assessing the usability and quality of adhesives for wood and load-bearing timber structures; c) for determining if the adhesive after bonding has a damaging influence on the strength of the wood due to chemical action.
Klebstoffe für tragende Holzbauteile - Prüfverfahren - Teil 3: Bestimmung des Einflusses von Säureschädigung der Holzfasern durch Temperatur- und Feuchtezyklen auf die Querzugfestigkeit
Dieser Teil von EN 302 beschreibt ein Prüfverfahren zur Bestimmung des Einflusses von Holzfaserschädigung auf die Klebstoffugenfestigkeit, verursacht durch die Wirkung von Säuren des Klebstoffes während einer zyklischen Klimabeanspruchung. Er ist für folgende Anwendungsfälle geeignet: a) Zuordnung des Klebstoffs zu einem in EN 301 angegebenen Klebstofftypen; b) Feststellung der Eignung und der Qualität von Klebstoffen für tragende Holzbauteile; c) Feststellung, ob der Klebstoff nach der Aushärtung infolge chemischer Vorgänge einen schädigenden Einfluss auf die Holzfestigkeit hat.
Adhésifs pour structures portantes en bois - Méthodes d'essais - Partie 3: Détermination de l'influence de l'attaque acide des fibres du bois résultant de traitements cycliques de température et d'humidité sur la résistance à la traction transversale
Cette partie de la norme EN 302 décrit une méthode d'évaluation de l'incidence sur la résistance du joint de l'endommagement des fibres du bois causé par l'action d'acides produits par l'adhésif au cours de cycles climatiques. Elle a pour but: a) de garantir la conformité d'un adhésif avec EN 301; b) de démontrer l'adéquation et la qualité d'adhesifs pour les structures portantes en bois; c) de déterminer si l'adhésif après collage montre un effet dommageable à la résistance du bois par suite d'action chimique.
