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 2 pre-treatments (PT1 and PT2) of the test specimens.
The test methods described in this document allow to determine the minimum top layer bonding quality, also for the use application on floor heating, and for the identification of bonding failure.
NOTE 1   For this application, the pre-treatments have proven to be suitable.
This document does not apply to the bonding quality of plywood if it is in use in the multilayer parquet construction.
NOTE 2   This standard doesn’t 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 Deckschicht von Mehrschichtparkettelementen nach EN 13489 mit unterschiedlichen Konstruktionsweisen, Abmessungen und Klebstoffen, die zur Verwendung als Bodenbelag im Innenbereich vorgesehen sind, zum Zeitpunkt der ersten Lieferung des Produkts bestimmt werden kann.
Das Dokument legt 2 Vorbehandlungen (PT1 und PT2) fest, denen die Prüfkörper unterzogen werden.
Die in diesem Dokument beschriebenen Prüfverfahren ermöglichen es, eine Mindestqualität der Deckschichtverklebung, auch für die Anwendung auf Fußbodenheizungen, zu bestimmen und Verklebungsversagen zu identifizieren.
ANMERKUNG 1   Für diese Anwendung haben sich die Vorbehandlungen als geeignet erwiesen.
Dieses Dokument gilt nicht für die Verklebungsqualität von Sperrholz, sofern dieses in der Mehrschichtparkettkonstruktion verwendet wird.
ANMERKUNG 2   Diese Norm 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 deux prétraitements (PT1 et PT2) des éprouvettes.
Les méthodes d’essai décrites dans le présent document permettent de déterminer la qualité de collage minimale de la couche supérieure. Elle est également utilisée pour les applications liées au chauffage par le sol et pour l’identification des défauts de collage.
NOTE 1   Les prétraitements se sont révélés appropriés pour cette application.
Le présent document ne s’applique pas à la qualité de collage du contreplaqué éventuellement utilisé dans la construction du parquet contrecollé.
NOTE 2   La présente norme 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.

Introduction
This document is one of a series of standards specifying requirements and test methods for wood flooring
and wood panelling and cladding.
This document specifies a test method to test and evaluate 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. There it was concluded
that a very good agreement in terms of delamination between the laboratories was observed when very low or very
high delamination was rated. At moderate delamination’s, there was strong scattering of the individual values
within the laboratories, partially between 0 % and 100 % delamination, but also between the laboratories
sometimes very significant differences in the results occurred. The test method is t
