Paints and varnishes - Coating materials and coating systems for exterior wood - Part 3: Natural weathering test

This document specifies a natural weathering test for exterior wood coating systems mainly intended for decoration and protection of planed and sawn wood.
The test provides a means of evaluating the performance of a wood coating system during outdoor exposure. It forms the basis for the performance specification in accordance with EN 927-2. It also facilitates the comparison of coating systems performance on different substrates including the wood species, or other wood modifications.

Beschichtungsstoffe - Beschichtungsstoffe und Beschichtungssysteme für Holz im Außenbereich - Teil 3: Freibewitterung

Dieses Dokument legt eine Freibewitterungsprüfung von Beschichtungssystemen für Holz im Außenbereich fest, die hauptsächlich zur Dekoration und zum Schutz von glattgehobeltem Schnittholz dienen.
Diese Prüfung dient zum Beurteilen des Verhaltens von Beschichtungssystemen für Holz, die dem Wetter ausgesetzt sind. Sie ist die Grundlage der Leistungsspezifikation nach EN 927 2. Sie erleichtert auch den Vergleich der Leistung verschiedener Beschichtungssysteme auf verschiedenen Substraten, einschließlich der Holzarten, oder anderen Holz Modifikationen.

Peintures et vernis - Produits de peinture et systèmes de peinture pour le bois en extérieur - Partie 3 : Essai de vieillissement naturel

Le présent document spécifie un essai de vieillissement naturel des systèmes de peinture pour le bois en extérieur principalement prévus pour la décoration et la protection des bois sciés et rabotés.
L’essai fournit un moyen permettant d’évaluer les performances d’un système de peinture pour bois durant son exposition en extérieur. Il sert de base pour l’élaboration de la spécification de performance selon l’EN 927-2. Il facilite également la comparaison des performances des systèmes de peinture sur divers subjectiles, y compris l’essence de bois, ou d’autres modifications du bois.

Barve in laki - Premazi in premazni sistemi za zaščito lesa za zunanjo uporabo - 3. del: Preskus s staranjem v naravnih razmerah

Ta evropski standard določa preskus s staranjem v naravnih razmerah za premazne sisteme za zaščito lesa v zunanji uporabi, katerih namen je okrasiti in zaščititi obeljen in žagan les.
Preskus je sredstvo za ugotavljanje delovanja premaznega sistema za les, ko je izpostavljen zunanjim vplivom. Predstavlja podlago za zahteve učinkovitosti v skladu s standardom EN 927-2.
