Furniture - Assessment of the surface reflectance

This document specifies a method for the assessment of the surface reflectance of furniture surfaces and relates to rigid surfaces of all finished products regardless of materials, except for finishes on leather and fabrics, which are excluded from this document.
The test is intended to be carried out on 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 method does not apply to extreme reflectances, i.e. below 15 % and above 75 %, because in the extreme reflectance range the results of the different measurement methods could deviate.
It is not applicable to some metallic paints and pearly coatings.

Möbel - Bewertung des Oberflächenreflexionsgrades

Dieses Dokument legt ein Prüfverfahren für die Bewertung des Oberflächenreflexionsgrades von ebenen Möbeloberflächen unabhängig vom Werkstoff fest, ausgenommen Oberflächen aus Leder und Textilien.
Die Prüfung wird im Allgemeinen am gebrauchsfertigen Möbel durchgeführt, kann aber auch an Prüfkörpern durchgeführt werden, die aus dem gleichen Werkstoff mit identischer Oberflächenbehandlung wie das Möbel bestehen und groß genug sind, die Prüfungen entsprechend durchführen zu können.
Das vorliegende Verfahren gilt nicht für extreme Reflexionsgrade, d. h. Helligkeit unter 15 % und über 75 %, da in diesem Reflexionsbereich die Ergebnisse zwischen den verschiedenen Messwerten voneinander abweichen können.
Dieses Prüfverfahren ist bei einigen Metallic- und Perlmuttlackierungen nicht anwendbar.

Meubles - Évaluation de la luminance lumineuse des surfaces

La présente norme européenne spécifie une méthode permettant d'évaluer la luminance lumineuse des surfaces des meubles et s'applique aux surfaces rigides de tous les produits finis, sans distinction de matériaux, à l'exception des finitions appliquées sur le cuir et les textiles, qui sont exclus de la présente norme européenne.
Cet essai est destiné à être réalisé sur des meubles finis, mais il peut être mené sur des panneaux d'essai dont le matériau et la finition sont identiques à ceux du produit fini et d'une taille suffisante pour satisfaire aux exigences de l'essai.
La méthode d'essai ne s'applique pas aux luminances lumineuses extrêmes, c'est-à-dire inférieures à 15 % et supérieures à 75 %, parce que, dans ces zones, les résultats des différentes méthodes de mesure peuvent dévier.
Elle ne s'applique pas à certaines peintures métallisées et certains revêtements nacrés.
