Resilient, textile, laminate and modular mechanical locked floor coverings - Light reflectance value (LRV) of a flooring surface

This document establishes a test and calculation method for resilient, textile and laminate floor coverings.
This document is also intended to provide guidance for manufacturers, specifiers and consumers, to enable them to choose the appropriate performance of floor covering regarding the light reflectancy of the use surface.

Elastische, textile, Laminat- und modulare mechanisch verriegelte Bodenbeläge - Lichtreflexionswert (LRV) einer Bodenoberfläche

Dieses Dokument legt ein Prüf  und Berechnungsverfahren für elastische, textile, Laminat- und modulare mechanisch verriegelte Bodenbeläge fest.
Dieses Dokument ist ebenfalls als Orientierungshilfe für Hersteller, Planer und Verbraucher gedacht, die geeignete Leistung von Bodenbelägen bezüglich der Lichtreflexion der Bodenoberfläche auszuwählen.

Revêtements de sol résilients, textiles, stratifiés et modulaires à clipsage mécanique - Coefficient de réflexion lumineuse (LRV) d'une surface de sol

Le présent document établit une méthode d'essai et de calcul pour les revêtements de sol résilients, textiles, stratifiés et modulaires à clipsage mécanique.
Il est également destiné à fournir des lignes directrices aux fabricants, aux prescripteurs et aux consommateurs, afin de leur permettre de choisir les performances appropriées des revêtements de sol concernant la réflexion lumineuse de la couche d'usage.

This European Standard was approved by CEN on 18 November 2019.

CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this

European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references

concerning such national standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN

member.

This European Standard exists in three official versions (English, French, German). A version in any other language made by

translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management

Centre has the same status as the official versions.
