Furniture - Assessment of the surface resistance to abrasion
This European Standard specifies a method for the assessment of the abrasion resistance of surfaces referred to under 7.4.
It does not apply to leather and textile surfaces.
It does not apply to the surfaces covered by EN 14434.
The test is intended to be carried out on a part of the finished furniture, but can 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.
The test shall be carried out on unused surfaces.
Möbel - Bewertung der Abriebfestigkeit von Oberflächen
Diese Europäische Norm legt ein Verfahren für die Bewertung der Abriebfestigkeit von Oberflächen fest, auf die in 7.4 Bezug genommen wird. Sie gilt nicht für Oberflächen aus Leder und Textilien. Sie gilt nicht für die Oberflächen von Wandtafeln nach EN 14434. Die Prüfung ist dafür vorgesehen, an einem Teil des gebrauchsfertigen Möbels durchgeführt zu werden, kann aber auch an Prüfkörpern durchgeführt werden, die aus dem gleichen Werkstoff mit identischer Ober-flächenbehandlung wie das fertige Produkt hergestellt wurden und groß genug sind, um den Prüfan-forderungen zu entsprechen. Die Prüfung muss auf unbenutzten Oberflächen durchgeführt werden.
Ameublement - Évaluation de la résistance de la surface à l'abrasion
La présente Norme européenne spécifie une méthode d’évaluation de la résistance à l’abrasion des surfaces
désignées en 7.4.
Elle ne s’applique ni au cuir, ni aux textiles.
Elle ne s’applique pas aux surfaces traitées dans l’EN 14434.
L’essai est destiné à être réalisé sur une partie des meubles finis, mais il peut être effectué sur des panneaux
d’essai du même matériau, de finition identique au meuble fini et de dimensions suffisantes pour satisfaire aux
exigences de l’essai.
L’essai doit être réalisé sur des surfaces neuves.
Pohištvo - Ocenjevanje odpornosti površine proti obrabi
Ta evropski standard določa preskusno metodo za odpornost površin proti obrabi, ki je omenjena v točki 7.4. Ne uporablja se za usnjene in tekstilne površine. Ne uporablja se za površine, ki jih pokriva standard FprEN 14434. 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. Preskus je treba izvesti na še nerabljenih površinah.

3.2 test panel panel including the test surface NOTE It may be cut from a finished item of furniture or it may be a separate panel produced in the same manner as the finished item of furniture. 3.3 test area part of the test surface under the wheels covered by the abrasion paper strips (5.3)
3.4 colour rendering index (CRI or Ra) unitless number that specifies how well the colour of an object appears under illumination by a light source compared to a reference light source 4 Principle The test simulates the ability of the furniture surface under test, to resist abrasive wear-through. Abrasion is achieved by rotating a specimen in contact with a pair of loaded cylindrical wheels covered with abrasive paper. The wheels are positioned so that their cylindrical faces are equidistant from the specimen's axis of rotation but not tangential to it. As they are turned by the rotating specimen they abrade an annular track on the specimen's surface. The number of revolutions of the specimen required to cause one defined degree of abrasion, is used as measurement of resistance to surface wear. 5 Apparatus and materials 5.1 Cleaning cloth White soft absorbent cloth. 5.2 Calibration plates Taber S-341) or equivalent, having a thickness of (0,8 ± 0,1) mm and a Brinell hardness of (48 ± 2) when tested in accordance with EN ISO 6506-1, except that the ball diameter shall be 5 mm and the load 360 N.
