Paints and varnishes - Methods of exposure to laboratory light sources - Part 2: Xenon-arc lamps (ISO 16474-2:2013)
ISO 16474-2:2013 specifies methods for exposing specimens to xenon-arc light in the presence of moisture to reproduce the weathering effects that occur when materials are exposed in actual end-use environments to daylight or to daylight filtered through window glass.
The specimens are exposed to filtered xenon-arc light under controlled conditions (temperature, humidity and/or wetting). Various types of xenon-arc lamps and various filter combinations may be used to meet all the requirements for testing different materials.
Specimen preparation and evaluation of the results are covered in other International Standards for specific materials.
General guidance is given in ISO 16474‑1. Xenon-arc exposures for plastics are described in ISO 4892‑2.
Beschichtungsstoffe - Künstliches Bestrahlen oder Bewittern in Geräten - Teil 2: Xenonbogenlampen (ISO 16474-2:2013)
Dieser Teil von ISO 16474 legt Verfahren zum Beanspruchen von Probenplatten mit Xenonbogenlicht in Anwesenheit von Feuchte fest, um die Einflüsse der Bewitterung zu reproduzieren, die auftreten, wenn Materialien im Endgebrauch in den vorhandenen Umgebungen durch Tageslicht oder durch Fensterglas gefiltertes Tageslicht beansprucht werden.
Die Probenplatten werden durch gefiltertes Xenonbogenlicht unter geregelten Bedingungen (Temperatur, Luftfeuchte und/oder Befeuchtung) beansprucht. Verschiedene Typen von Xenonbogenlampen und verschiedene Kombinationen von Filtern dürfen angewendet werden, um alle Anforderungen zu erfüllen, die bei der Prüfung unterschiedlicher Materialien gestellt werden.
Die Herstellung der Probenplatten und die Bewertung der Ergebnisse werden in anderen Internationalen Normen für spezielle Materialien behandelt.
Eine allgemeine Anleitung wird in ISO 16474-1 gegeben.
ANMERKUNG Die Beanspruchung von Kunststoffen mit Xenonbogenlampen ist in ISO 4892-2 beschrieben.
Peintures et vernis - Méthodes d'exposition à des sources lumineuses de laboratoire - Partie 2: Lampes à arc au xénon (ISO 16474-2:2013)
L'ISO 16474-2:2013 spécifie des méthodes pour l'exposition d'éprouvettes à des sources lumineuses à arc au xénon en présence d'humidité pour reproduire les effets de vieillissement qui se produisent lorsque des matériaux sont exposés, dans les environnements d'utilisation finale réels, à la lumière du jour ou bien à la lumière du jour filtrée à travers un vitrage de fenêtre.
Les éprouvettes sont exposées à des sources lumineuses à arc au xénon filtrées, dans des conditions maîtrisées (température, humidité et/ou mouillage). Divers types de lampes à arc au xénon et différentes combinaisons de filtres peuvent être utilisés pour répondre à toutes les exigences relatives aux essais de différents matériaux.
La préparation des éprouvettes et l'évaluation des résultats sont traitées dans d'autres Normes internationales concernant les matériaux spécifiques.
Des lignes directrices générales sont données dans l'ISO 16474‑1. L'exposition des matières plastiques aux lampes à arc au xénon est décrite dans l'ISO 4892‑2.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directives
