(Main)Furniture - Assessment of the surface reflectance
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.
This document is applicable to the test, 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 is not applicable to some metallic paints and pearly coatings.
Möbel - Bewertung des Oberflächenreflexionsgrades
Dieses Dokument legt ein Verfahren zur Bewertung des Oberflächenreflexionsgrades von Möbeloberflächen fest und bezieht sich auf starre Oberflächen aller fertigen Produkte unabhängig von den Werkstoffen; nicht von diesem Dokument erfasst sind Oberflächenbehandlungen auf Leder und Textilien.
Dieses Dokument ist für die Prüfung anzuwenden, die für die Durchführung am gebrauchsfertigen Möbel vorgesehen ist, aber auch an Prüfkörpern durchgeführt werden kann, die aus dem gleichen Werkstoff mit identischer Oberflächenbehandlung wie das Möbel bestehen und groß genug sind, um den Anforderungen der Prüfung zu entsprechen.
Das Prüfverfahren ist bei einigen Metallic- und Perlmuttlackierungen nicht anzuwenden.
Ameublement - Évaluation de la luminance lumineuse des surfaces
Le présent document 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 exclues du présent document.
Le présent document est applicable à l’essai 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 à certaines peintures métallisées et certains revêtements nacrés.
Pohištvo - Ocenjevanje odbojnosti površine
Ta dokument določa metodo za ocenjevanje odbojnosti površin pohištva in se navezuje na trdne površine vseh končanih izdelkov ne glede na material, razen za zaključke iz usnja in blaga, ki so izključeni iz tega dokumenta.
Preskus naj bi se izvedel na končanem kosu pohištva, izvesti pa ga je mogoče tudi na preskusnih ploščah iz istega materiala, ki so obdelane na identičen način kot končan izdelek in dovolj velike, da ustrezajo zahtevam preskusa.
Preskusna metoda se ne uporablja za nekatere kovinske barve in biserne premaze.
