Furniture - Assessment of the surface resistance to scratching

This European Standard specifies a method for the assessment of the surface resistance to penetrating 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 scratches that may only 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

Diese Europäische Norm legt ein Verfahren für die Bewertung der Oberflächenbeständigkeit gegen tiefe und deutliche Kratzmarkierungen fest und gilt für die starren Oberflächen aller fertigen Produkte unabhängig vom Werkstoff.
Sie gilt nicht für fertige Produkte aus Leder und Textilien.
Verfahren A ist für alle Arten von Oberflächenbeschichtung und Auflagen geeignet, außer für Melaminflächen und HPL (Hochdruckschichtstoffplatten). Es bildet messbare durchdringende und/oder verformende Kratzer nach.
Verfahren B ist für alle Oberflächenarten geeignet. Es bildet erste sichtbare Kratzer nach, die lediglich eine Veränderung des Glanzes  sein können.
Die Prüfung ist im Allgemeinen an einem Teil des gebrauchsfertigen Möbels durchzuführen, kann aber auch an Prüfkörpern durchgeführt werden, die aus dem gleichen Werkstoff mit identischer Oberflächenbehandlung wie das fertige Produkt hergestellt wurden und groß genug sind, um den Prüfanforderungen zu entsprechen.
Die Prüfung ist in jedem Fall an unbenutzten Oberflächen durchzuführen.

Ameublement - Evaluation de la résistance de la surface à la rayure

La présente Norme européenne spécifie une méthode d’évaluation de la résistance de la surface aux rayures par pénétration et s’applique aux surfaces rigides de tous les produits finis, indépendamment des matériaux.
Elle ne s’applique pas aux finitions appliquées sur le cuir ou les textiles.
La méthode A convient à tous les types de revêtements de surface, excepté les revêtements de mélamine et les HPL. 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 rayures visibles qui peuvent n’être qu’un changement de brillance.
L’essai est destiné à être réalisé sur une partie du meuble fini mais il peut être effectué sur des panneaux d’essai constitués du même matériau, de finition identique au produit fini et de dimensions suffisantes pour satisfaire aux spécifications de l’essai.
Il est essentiel que l’essai soit réalisé sur des surfaces neuves.

Pohištvo - Ocenjevanje odpornosti površine proti razenju

Ta evropski standard določa preskusno metodo za odpornost površin proti globokemu razenju. Nanaša se na trdne površine vseh končanih izdelkov, ne glede na njihov material. Ne uporablja se za površine, prekrite z usnjem ali tkanino. Metoda A je primerna za vse tipe premazov in prevlek površin, razen za plošče, katerih površina je prekrita z melaminom (v skladu z EN 14322) in HPL (v skladu z EN 438-1). Metoda simulira izmerljive raze, ki prodrejo v globino in/ali povzročijo deformacije. Metoda B je primerna za vse vrste površin. Metoda simulira prve vidne raze, ki lahko pomenijo samo spremembo sijaja. Preskus naj bi se izvedel na delu končanega kosa pohištva. Lahko pa se izvede tudi na preskusnih ploščah iz istega materiala, ki so obdelane na identičen način kot končan izdelek, njihova velikost pa mora biti dovolj velika, da ustreza zahtevam preskusa. Pomembno je, da se preskus izvede na še nerabljenih površinah.
