Plastics - Methods of exposure to laboratory light sources - Part 2: Xenon-arc lamps (ISO 4892-2:2013)
ISO 4892-2:2013 specifies methods for exposing specimens to xenon-arc light in the presence of moisture to reproduce the weathering effects (temperature, humidity and/or wetting) that occur when materials are exposed in actual end-use environments to daylight or to daylight filtered through window glass.
Kunststoffe - Künstliches Bestrahlen oder Bewittern in Geräten - Teil 2: Xenonbogenlampen (ISO 4892-2:2013)
Dieser Teil von ISO 4892 legt die Verfahren fest, bei denen Probekörper in einem Gerät einer Xenon-bogenstrahlung, Feuchtigkeit ausgesetzt werden, um die Bewitterungseffekte (Temperatur, Luftfeuchte und/oder Benässung) nachzubilden, die auftreten, wenn Werkstoffe in realen, im Endgebrauch vorhandenen Umgebungen der Globalstrahlung oder Globalstrahlung hinter Fensterglas ausgesetzt sind.
Die Vorbereitung der Probekörper und die Auswertung der Ergebnisse werden in anderen, für bestimmte Werkstoffe vorgesehenen Internationalen Normen behandelt.
Eine allgemeine Anleitung ist in ISO 4892 1 gegeben.
ANMERKUNG Die Beanspruchung von Beschichtungsstoffen durch Xenonbogenstrahlung ist in ISO 11341 [1] beschrieben.
Plastiques - Méthodes d'exposition à des sources lumineuses de laboratoire - Partie 2: lampes à arc au xénon (ISO 4892-2:2013)
L'ISO 4892-2:2013 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 (température, humidité et/ou mouillage) qui se produisent lorsque des matériaux sont exposés, dans des environnements d'utilisation finale réels, à la lumière du jour et à la lumière du jour filtrée à travers un vitrage de fenêtre.
Polimerni materiali - Metode izpostavitve laboratorijskim virom svetlobe - 2. del: Ksenonske svetilke (ISO 4892-2:2013)
Ta del standarda ISO 4892 navaja metode izpostavitve primerkov ksenonski svetlobi v vlažnem okolju, kar poustvari vremenske vplive (temperaturo, vlažnost in/ali močenje), do katerih pride, ko so materiali v okolju, kjer se uporabljajo, izpostavljeni neposredni dnevni svetlobi ali dnevni svetlobi, ki se filtrira skozi okensko steklo. Priprava primerkov in vrednotenje rezultatov sta obravnavana v drugih mednarodnih standardih za določene materiale. Splošne smernice so podane v standardu ISO 4892-1.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International
Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies
casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 4892-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 6, Ageing,
chemical and environmental resistance.
This third edition cancels and replaces the second edition (ISO 4892-2:2006), which has been technically
revised. It also cancels and replaces the Amendment ISO 4892-2:2006/Amd.1:2009.
ISO 4892 consists of the following parts, under the general title Plastics — Methods of exposure to

Part 2:
Xenon-arc lamps
1 Scope
This part of ISO 4892 specifies methods for exposing specimens to xenon-arc light in the presence
of moisture to reproduce the weathering effects (temperature, humidity and/or wetting) that occur
when materials are exposed in actual end-use environments to daylight or to daylight filtered through
window glass.
Specimen preparation and evaluation of the results are covered in other International Standards for
specific materials.
General guidance is given in ISO 4892-1.
NOTE Xenon-arc exposures of paints and varnishes are described in ISO 11341.
