Furniture - Assessment of surface resistance to cold liquids
This European standard specifies a method for the assessment of the resistance to cold liquids of all rigid furniture surfaces regardless of materials.
It does not apply to leather and textile surfaces.
This European standard specifies a method for the assessment of the resistance to cold liquids of all rigid furniture surfaces regardless of materials. It does not apply to leather and textile surfaces. 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. The type and number of test liquids (Annex A) and the test periods (Table 1) shall be stated in requirement specifications or shall be agreed upon between purchaser and supplier or interested parties. Annex A (normative) includes a selection of suitable test liquids. Other liquids can be used if required.
Möbel - Bewertung der Beständigkeit von Oberflächen gegen kalte Flüssigkeiten
Diese Europäische Norm legt ein Bewertungsverfahren für die Beständigkeit von Oberflächen gegen kalte
Flüssigkeiten für starre Möbeloberflächen unabhängig von den verwendeten Werkstoffen fest.
Sie gilt nicht für Oberflächen aus Leder und Textilien.
Die Prüfung ist zur Durchführung an einem Teil des oberflächenbehandelten Möbelstücks gedacht, kann aber
auch an Prüflingen durchgeführt werden, die aus dem gleichen Werkstoff mit identischer Oberflächenbehandlung
wie das oberflächenbehandelte Produkt und groß genug sind, um den Anforderungen der Prüfung zu
entsprechen.
Die Prüfung muss auf unbenutzten Oberflächen durchgeführt werden.
Die Art und Anzahl der Prüfflüssigkeiten (Anhang A) und Prüfzeiten (Tabelle 1) müssen in den Anforderungsspezifikationen
dargelegt oder zwischen Hersteller und Händler oder den jeweiligen Interessenten festgelegt
werden.
Anhang A (normativ) beinhaltet eine Auswahl geeigneter Prüfflüssigkeiten. Falls es notwendig ist, können
andere Flüssigkeiten herangezogen werden.
Anhang B (informativ) beschreibt eine direkte Lichtquelle, die zur Bewertung des Prüfbereichs verwendet
werden kann.
Meubles - Évaluation de la résistance de la surface aux liquides froids
La présente Norme européenne spécifie une méthode d’évaluation de la résistance aux liquides froids de
toutes les surfaces d’ameublement rigides, indépendamment des matériaux.
Elle ne s’applique pas aux surfaces en cuir et en textile.
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.
L’essai doit être conduit sur des surfaces neuves.
Le type et le nombre des liquides d’essai ainsi que les durées d’essai (Annexe A) sont fixés dans les
spécifications ou doivent faire l’objet d’un accord entre l’acheteur et le fournisseur ou les parties intéressées.
L’Annexe A (normative) inclus une sélection de liquides d’essai appropriés. D’autres liquides peuvent être
employés si nécessaire.
L’Annexe B (informative) décrit une source de lumière directe.
Pohištvo - Ocenjevanje odpornosti površine proti hladnim tekočinam (vključno z dopolnilom A1)
Ta evropski standard določa metodo za ocenjevanje odpornosti vseh trdnih površin pohištva ne glede na material proti hladnim tekočinam. Ne uporablja se za usnjene in tekstilne površine. 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. Vrsto in število preskusnih tekočin (dodatek A) ter preskusna obdobja (preglednica 1) je treba navesti v specifikacijah zahtev ali pa se morajo glede njih dogovoriti kupec in dobavitelj ali zainteresirane strani. Dodatek A (normativni) vključuje izbor ustreznih preskusnih tekočin. Po potrebi se lahko uporabijo druge tekočine.
