Furniture - Assessment of surface resistance to cold liquids
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. 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. Annex B (informative) describes a direct light source.
Möbel - Bewertung der Beständigkeit von Oberflächen gegen kalte Flüssigkeiten
Diese Europäische Norm legt ein Bewertungsverfahren für die Beständigkeit von Oberflächen gegen kalte Flüssigkei¬ten fest und gilt für starre Oberflächen von oberflächenbehandelten Möbeln unabhängig vom verwendeten Werkstoff, außer für Oberflächen aus Leder und Textilien.
Die Prüfungen werden gewöhnlich am Möbel durchgeführt, können aber auch an Prüfkörpern durchgeführt werden, die aus dem gleichen Werkstoff mit identischer Oberflächenbehandlung wie das Möbel 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 und Prüfzeiten (zu entnehmen aus der Tabelle 1 in Abschnitt 7) sind in den Spezifikationen dargelegt oder werden zwischen Hersteller und Händler oder den jeweiligen Interessenten festgelegt.
Eine Auswahl geeigneter Prüfflüssigkeiten ist im Anhang A aufgelistet, falls es notwendig ist können jedoch andere Flüssigkeiten herangezogen werden.
Meubles - Évaluation de la résistance de la surface aux liquides froids
La présente Norme européenne spécifie une méthode d’évaluation de la résistance de la surface aux liquides
froids 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.
L’essai est destiné a etre réalisé sur une partie du meuble fini mais il peut etre effectué sur des panneaux
d’essai constitués du meme matériau, de finition identique au produit fini et de dimensions suffisantes pour
satisfaire aux spécifications de l’essai.
L’essai doit etre conduit sur des surfaces neuves.
Le type et le nombre des liquides d’essai ainsi que les durées d’essai (a choisir dans le Tableau 1, Article 7)
sont fixés dans les spécifications ou font l’objet d’un accord entre l’acheteur et le fournisseur ou les parties
intéressées.
Une sélection de liquides d’essai appropriés est donnée en Annexe A mais d’autres liquides peuvent etre
employés, si nécessaire.
