Laminate floor coverings - Elements with a surface layer based on aminoplastic thermosetting resins - Specifications, requirements and test methods
This European Standard specifies characteristics, states requirements and gives test methods for laminate floor coverings (as defined in 3.1).
It includes a classification system, based on EN 685, giving practical requirements for areas of use and levels of use, to indicate where laminate floor coverings will give satisfactory service and to encourage the consumer to make an informed choice. It also specifies requirements for marking and packaging.
Laminate floor coverings are considered for domestic and commercial levels of use. This standard does not specify requirements relating to areas which are subjected to frequent wetting, such as bathrooms, laundry rooms or saunas, but it does apply to domestic kitchens.
Laminatböden - Elemente mit einer Deckschicht auf Basis aminoplastischer, wärmehärtbarer Harze - Spezifikationen, Anforderungen und Prüfverfahren
Diese Europäische Norm legt Merkmale, Anforderungen und Prüfverfahren für Laminatböden fest (wie in
3.1 definiert).
Sie enthält ein Klassifizierungssystem, das auf EN 685 basiert, mit praktischen Anforderungen für bestimmte
Verwendungsbereiche und Beanspruchungsklassen. Dies dient dazu aufzuzeigen, in welchen Bereichen
Laminatböden zufrieden stellend eingesetzt werden können sowie dazu den Verbraucher in die Lage zu
versetzen, informiert eine Auswahl zu treffen. Sie legt ebenfalls Anforderungen an Kennzeichnung und
Verpackung fest.
Für Laminatböden werden die Anwendungsgebiete ‘Wohnen’ und ‘Gewerblich’ berücksichtigt. Diese Norm
legt keine Anforderungen für Bereiche fest, die regelmäßig Nässe ausgesetzt sind (wie etwa Badezimmer,
Hauswirtschaftsräume oder Saunen); sie gilt jedoch für Küchen im Wohnbereich.
Revetements de sol stratifiés - Elements dont la surface est a base de résines aminoplastes thermodurcissables - Spécifications, exigences et méthodes d'essai
La présente Norme européenne spécifie les caractéristiques, fixe les exigences et donne les méthodes
d’essai pour les revetements de sol stratifiés (tels que définis en 3.1).
Elle comporte un systeme de classification, basé sur l’EN 685, définissant des exigences pratiques pour les
zones et niveaux d’utilisation, afin d’indiquer dans quels cas les revetements de sol stratifiés fournissent un
service satisfaisant et d’encourager le consommateur a faire un choix informé. Elle précise également les
exigences relatives au marquage et a l’emballage.
Les revetements de sol stratifiés sont destinés a un usage domestique et commercial. La présente norme ne
précise pas les exigences relatives aux zones présentant des risques d’humidification fréquente comme les
salles de bain, les buanderies ou les saunas ; en revanche, elle s’applique aux cuisines domestiques.

3 Terms and definitions For the purposes of this European Standard, the following terms and definitions apply. 3.1
laminate floor covering floor covering with a surface layer consisting of one or more thin sheets of a fibrous material (usually paper), impregnated with aminoplastic, thermosetting resins (usually melamine) NOTE By the simultaneous action of heat and pressure, these sheets are either pressed as such (HPL, CPL, Compact), and in the case of HPL and CPL bonded on a substrate (usually wood-based panels), or in the case of DPL directly pressed on a substrate (usually wood-based panels). The product is usually finished with a backing (e.g. HPL, CPL, impregnated papers and veneers), primarily used as a balancing material. 3.1.1
surface layer upper decorative layer intended to be the visible side when the floor is installed.
NOTE This layer consists of sheets impregnated with thermosetting resins, pressed by three different techniques. High-pressure laminates (HPL), as defined in EN 438; Continuous pressed laminates (CPL); Directly pressed to the substrate (DPL). 3.1.2
substrate core material of the laminate floor covering NOTE It is generally a particleboard, as defined in EN 309, or a Medium Density Fibreboard or High Density Fibreboard (MDF or HDF), as defined in EN 316. 3.1.3
backing layer opposite to the surface layer NOTE The backing is generally made of HPL, CPL, impregnated papers or veneers. It is primarily used to balance and stabilise the product. 3.2
laminate floor covering element consisting of a surface layer, a substrate and a backing, shaped and machined on its sides to the appropriate dimensions
NOTE See Figure 1. The elements are usually tongued and grooved to facilitate assembly at installation.

Determination of dimensional variations after changes in relative humidity C.1 General Test in accordance with EN 318, with the following modifications. C.2 Sampling Take from each of three laminate floor-covering elements one test specimen in the length direction and another in the width direction. The test specimens may be taken from any part of the element as long as the length direction and width direction is maintained (see Figure C.1). The dimension of a test specimen shall be (180 ± 1) mm x (20 ± 1) mm. If the nominal width of the element is less than 180 mm, no test specimen in the width direction shall be taken. 123 Key 1 Test specimen taken in the width direction 2 Test specimen taken in the length direction 3 Laminate floor covering element Figure C.1 — Example of sampling C.3 Conditioning Test specimens are measured in the received state. For type approval or verification purposes, the test specimens shall be stabilized to a constant mass in an atmosphere of (23 ± 2) ºC and (50 ± 5) % relative humidity.

The achieved results cannot be scaled-up to large flooring elements, and should never be used as a basis for calculation of the dimensional changes of a laminate floor covering in service.

D.4.2 Bonding the steel pad to the surface To obtain sufficient bonding to the decorative surface layer it may be necessary to sandpaper the surface with a coarse-grained abrasive paper.
D.4.3 Determination of force at fracture Record the force at fracture for each test specimen. Ignore the results for any test specimens which display total or partial breakage of the bond between the steel pad and the test specimen, or between the test specimen and the aluminium plate. Under these circumstances, repeat the test, using new test specimens. D.5 Calculation and expression of results Calculate the individual value for each test specimen tested. Express the results to the nearest 0,01 N/mm2.
