Furniture - Assessment of the surface resistance to scratching
This document specifies a method for the assessment of the surface resistance to different kinds of visible scratches. It relates to the rigid surfaces of all finished products, regardless of their material.
It does not apply to finishes on leather and fabrics.
Method A is suitable for all types of surface coatings and coverings except for melamine faced boards (according to EN 14322) and HPL (according to EN 438 1). It simulates measurable penetrating and/or deforming scratches.
Method B is suitable for all types of surfaces. It simulates first visible traces (e.g. scratches, marks) that can also be a change in the gloss.
The test is intended to be carried out on a part of finished furniture. It can, however, be carried out on test panels of the same material, finished in an identical manner to the finished product, and of a size sufficient to meet the requirements of the test.
It is essential that the test be carried out on unused surfaces.
Möbel - Bewertung der Kratzfestigkeit von Oberflächen
Dieses Dokument legt ein Verfahren für die Bewertung der Oberflächenbeständigkeit gegen verschiedenartige sichtbare Kratzer fest. Es gilt für die starren Oberflächen aller fertigen Produkte unabhängig von ihrem Werkstoff.
Es ist nicht anwendbar für Oberflächenbehandlungen auf Leder und Textilien.
Verfahren A ist für alle Arten von Oberflächenbeschichtungen und -beläge geeignet, außer für melaminbeschichtete Platten (nach EN 14322) und HPL (Hochdruck-Schichtstoffplatten; en: high pressure laminates) (nach EN 438-1). Es bildet messbare durchdringende und/oder verformende Kratzer nach.
Verfahren B ist für alle Oberflächenarten geeignet. Es bildet erste sichtbare Kratzspuren (z. B. Kratzer, Spuren) nach, bei denen es sich auch um eine Glanzänderung handeln kann.
Die Prüfung ist dafür vorgesehen, an einem Teil des gebrauchsfertigen Möbels durchgeführt zu werden. Sie kann aber auch an Prüfkörpern durchgeführt werden, die aus dem gleichen Werkstoff hergestellt und der gleichen Oberflächenbehandlung unterzogen wurden wie das fertige Produkt, und die groß genug sind, um den Prüfanforderungen zu entsprechen.
Es ist von grundlegender Bedeutung, dass die Prüfung auf unbenutzten Oberflächen durchgeführt wird.
Ameublement - Evaluation de la résistance de la surface à la rayure
Le présent document spécifie une méthode d’évaluation de la résistance de la surface à différents types de rayures visibles. Elle s’applique aux surfaces rigides de tous les produits finis, indépendamment de leur matériau.
Elle ne s’applique pas aux finitions appliquées sur le cuir ou les étoffes.
La méthode A convient à tous les types de revêtements de surface, excepté les panneaux surfacés mélaminés (selon l’EN 14322) et les HPL (selon l’EN 438-1). Elle simule des rayures par pénétration et/ou par déformation mesurables.
La méthode B convient à tous les types de surface. Elle simule les premières traces visibles (par exemple, rayures, marques), qui peuvent n’être qu’un changement de brillance.
L’essai est destiné à être réalisé sur une partie du meuble fini. Il peut cependant être effectué sur des panneaux d’essai constitués du même matériau, de finition identique à celle du produit fini et de dimensions suffisantes pour satisfaire aux exigences de l’essai.
Il est essentiel que l’essai soit réalisé sur des surfaces neuves.
