Wood flooring and parquet - Determination of top layer delamination of multilayer elements - Test method
This document specifies a test method to determine the top layer delamination of multilayer parquet elements according to EN 13489 with different structures, dimensions and adhesives for internal use as flooring, at the time of the first delivery of the product.
The document specifies a test method with three aging-treatments (AT1, AT2 and AT3) of the test specimens.
The test method described in this document allows to determine a top layer bonding quality, also for parquet used on floor heating, and for the identification of bonding failure.
NOTE 1 For bottom layer of three layers elements the test method is applicable even if the experience is limited.
AT1 is a suitable treatment for the prognosis of multilayer parquets under dry indoor conditions and can be applied for all type of glues of parquets. It can be used for main underfloor heating systems.
AT2 is a suitable treatment for the assessment of multilayer parquets with PVAc-glues for top layer bonding.
AT3 is a suitable treatment for the assessment of multilayer parquets with different type of glues other than PVA-c for top layer bonding.
This document does not apply to the bonding quality of plywood if it is in use in the multilayer parquet construction.
NOTE 2 This document does not allow to estimate the compatibility of use in wet conditions.
Holzfußböden und Parkett - Bestimmung der Delaminierung der Decklagen von Mehrschichtelementen - Prüfverfahren
Dieses Dokument legt ein Prüfverfahren fest, mit dem die Delaminierung der Decklage von Mehrschicht-parkettelementen nach EN 13489 mit unterschiedlichen Aufbauten, Abmessungen und Kleb¬stoffen, die zur Verwendung als Bodenbelag im Innenbereich vorgesehen sind, zum Zeitpunkt der ersten Lieferung des Produkts bestimmt werden kann.
Das Dokument legt ein Prüfverfahren mit drei Alterungsbehandlungen (AT1, AT2 und AT3) fest, denen die Prüfkörper unterzogen werden.
Das in diesem Dokument beschriebene Prüfverfahren ermöglicht es, eine Qualität der Decklagenverklebung, auch für auf Fußbodenheizungen verlegtes Parkett, zu bestimmen und Verklebungsversagen zu identifizieren.
ANMERKUNG 1 Das Prüfverfahren ist auf die untere Schicht von Dreischichtelementen anwendbar, auch wenn die vorliegenden Erfahrungen begrenzt sind.
AT1 ist eine Behandlung, die für Prognosen zum Verhalten von Mehrschichtparkett unter trockenen Innenraumbedingungen geeignet ist und für alle Arten von Parkettklebern angewendet werden kann. Sie kann für Fußbodenheizungen verwendet werden, die als Permanentheizung genutzt werden.
AT2 ist eine geeignete Behandlung zur Beurteilung von Mehrschichtparkett, bei dem für die Decklagen-verklebung PVAc Klebstoffe verwendet wurden.
AT3 ist eine geeignete Behandlung zur Beurteilung von Mehrschichtparkett, bei dem für die Decklagenverklebung andere Klebstoffarten als PVAc verwendet wurden.
Dieses Dokument gilt nicht für die Verklebungsqualität von Sperrholz, sofern dieses in der Mehrschichtparkettkonstruktion verwendet wird.
ANMERKUNG 2 Dieses Dokument ermöglicht es nicht, die Verwendung unter feuchten Bedingungen einzuschätzen.
Planchers en bois et parquets - Détermination du décollement de la couche supérieure des éléments contrecollés - Méthode d'essai
Le présent document spécifie une méthode d’essai visant à déterminer le décollement de la couche supérieure des éléments de parquets contrecollés conformément à l’EN 13489 avec différentes structures, dimensions et colles et pour utilisation en intérieur comme revêtement de sol, au moment de la première livraison du produit.
Le document spécifie une méthode d’essai avec trois traitements de vieillissement (AT1, AT2 et AT3) des éprouvettes.
La méthode d’essai décrite dans le présent document permet de déterminer une qualité de collage de la couche supérieure, également pour le parquet utilisé sur le chauffage par le sol ainsi que pour l’identification de défauts de collage.
NOTE 1 Pour la couche inférieure des trois éléments de couche, la méthode d’essai s’applique malgré l’expérience limitée.
AT1 est un traitement adapté à la caractérisation de parquets contrecollés en conditions intérieures sèches, et il peut être appliqué pour tous les types de colles de parquets. Il peut être utilisé dans le cas de chauffage par le sol, pour les principaux systèmes de chauffage au sol.
AT2 est un traitement adapté à l’évaluation des parquets contrecollés avec des colles PVAc pour le collage de la couche supérieure.
AT3 est un traitement adapté à l’évaluation des parquets contrecollés avec différents types de colles autres que les colles PVAc pour le collage de la couche supérieure.
Le présent document ne s’applique pas à la qualité de collage du contreplaqué éventuellement utilisé dans la construction du parquet contrecollé.
NOTE 2 Le présent document ne permet pas d’estimer la compatibilité d’utilisation en conditions humides.

Introduction
This document is one of a series of standards specifying requirements and test methods for wood flooring
and parquet.
This document specifies a test method with three aging-treatments to measure the top layer bonding of
multilayer parquet with different structures, dimensions and adhesives.
Floor heating systems, low energy or passive houses as well as public areas with heavy exposures
represent a potential high stress to wood flooring and parquet elements that require them to withstand
the effects of temperature and humidity occurring in practical installation situations.
The test method described in this document simulates these situations. By that the already existing large
amount of knowledge about multilayer parquet and values for product characteristics attested by long
use and experience is extended for the benefit of producers, installers, dealers and customers. For new
products, technical data will have to be verified by testing.
NOTE A Round Robin trial was carried out involving seven international laboratories. The test method is
therefore suitable as a yes/no decision for failure in the top layer bonding or poor product quality, but it does not
allow quantification. It is possible to use it in conjunction with low limits of allowable delamination.
