Adhesives for load-bearing timber structures - Test methods - Part 7: Determination of the working life under referenced conditions
This part of EN 302 specifies a method for determining the working life for adhesives for load-bearing timber structures, by a viscosity test. This method is not suitable for determining the working life of a multi-component adhesive whose actual working life is very short. This document is only intended for obtaining a reliable basis for comparison between adhesives. The method gives results which cannot be applied to the safe manufacture of timber structures without modifications for the influences of factory temperature and relative air humidity.
Klebstoffe für tragende Holzbauteile - Prüfverfahren - Teil 7: Bestimmung der Gebrauchsdauer bei Referenzbedingungen
Dieser Teil von EN 302 legt ein Verfahren zur Bestimmung der Gebrauchsdauer für Klebstoffe für tragende Holzbauteile mit einer Viskositätsprüfung fest.
Dieses Verfahren ist nicht geeignet zur Bestimmung der Gebrauchsdauer eines Mehrkomponentenklebstoffs, dessen tatsächliche Gebrauchsdauer sehr kurz ist.
Dieses Dokument dient nur dazu, Klebstoffe auf einer zuverlässigen Grundlage zu vergleichen. Die nach diesem Verfahren erhaltenen Ergebnisse können nicht unverändert für die zuverlässige Herstellung von Holzbauteilen verwendet werden, ohne die Einflüsse von Verarbeitungstemperatur und relativer Luftfeuchte zu berücksichtigen.
Adhésifs pour structures portantes en bois - Méthodes d´essai - Partie 7 : Détermination de la durée conventionelle d´utilisation
La présente Norme européenne spécifie une méthode permettant de déterminer, à partir d'un essai de viscosité, la durée d'utilisation des adhésifs mélangés à un durcisseur pour structures portantes en bois dans des conditions de référence.
Cette méthode n'est pas applicable pour déterminer la durée d'utilisation d'un adhésif multi-composants dont la durée de vie réelle est très courte.
Le présent document vise seulement à fournir une base fiable de comparaison des adhésifs. La méthode fournit des résultats qui ne sont pas applicables sans risque à la fabrication de structures en bois, sans des modifications prenant en compte l'influence de la température et de l'humidité relative de l'air dans l'usine.
Lepila za nosilne lesene konstrukcije - Preskusne metode - 7. del: Določanje dobe trajanja pri referenčnih pogojih
Ta del standarda EN 302 opisuje metodo za določanje dobe trajanja lepil za nosilne lesene strukture s preskusom viskoznosti. Ta metoda ni ustrezna za določanje dobe trajanja večkomponentnega lepila z zelo kratko dobo trajanja. Ta dokument je namenjen le za pridobivanje zanesljive podlage za primerjavo lepil. Z metodo se pridobijo rezultati, ki jih ni mogoče uporabiti za varno proizvodnjo lesenih struktur brez prilagoditev zaradi vplivov tovarniške temperature in relativne vlažnosti zraka.

EN 301, EN 302 Parts 1 to 7 and EN 15416-2 have the following titles.
EN 301, Adhesives, phenolic and aminoplastic, for load-bearing timber structures — Classification and
performance requirements
EN 302, Adhesives for load-bearing timber structures — Test methods
Part 1: Determination of longitudinal tensile shear strength
Part 2: Determination of resistance to delamination
Part 3: Determination of the effect of acid damage to wood fibres by temperature and humidity cycling on
the transverse tensile strength
Part 4: Determination of the effects of wood shrinkage on the shear strength
Part 5: Determination of the maximum assembly time under referenced conditions
Part 6: Determination of the minimum pressing time under referenced conditions
Part 7: Determination of the working life under referenced conditions
EN 15416-2, Adhesives for load bearing timber structures other than phenolic and aminoplastic — Test
