(Main)Adhesives for non-structural wood applications — Test method and requirements for resistance to static load
Adhesives for non-structural wood applications — Test method and requirements for resistance to static load
This document specifies a method for determining the ability of a test piece bonded with a thermoplastic adhesive, to support a given load for a specified time without fracture or excessive distortion, and specifies performance requirements for mean survival time. It should be used in conjunction with ISO 19209 and ISO 19210, which describe durability classes and corresponding test methods for non-structural wood adhesives based on their ability to withstand various water treatments and relatively rapidly applied loads. The test described in this standard may be used to assess joints made with thin glue line, as defined in ISO 19210. NOTE The test described in this document is not a mandatory requirement for the classification of adhesives into the classes D1, D2, D3 and D4 given in ISO 19209. It is an additional test that can be specified by a purchaser if required.
Adhésifs pour bois à usages non structuraux — Méthode d'essai et exigences pour la résistance à la charge statique
Le présent document spécifie une méthode permettant de déterminer la capacité d’une éprouvette, collée avec un adhésif thermoplastique, à résister à une charge donnée pendant une durée spécifiée sans se rompre ni se déformer exagérément et spécifie les exigences de performance pour une durée de vie moyenne. Il convient de l’utiliser conjointement avec l’ISO 19209 et l’ISO 19210 qui décrivent les classes de durabilité et les méthodes d’essai correspondant aux adhésifs pour bois à usages non structuraux en se reposant sur la capacité de ces derniers à résister à différents traitements par l’eau et aux charges appliquées rapidement. L’essai décrit dans la présente norme peut servir à évaluer les collages réalisés avec des joints minces définis dans l’ISO 19210. NOTE L’essai décrit dans le présent document ne constitue pas une exigence obligatoire pour le classement des adhésifs dans les classes DI, D2, D3 et D4 définies dans l’ISO 19209. Il s’agit d’un essai supplémentaire qui peut éventuellement être prescrit par un acheteur.
