Plastics - Methods of exposure to laboratory light sources - Part 3: Fluorescent UV lamps (ISO 4892-3:2016)
This part of ISO 4892 specifies methods for exposing specimens to fluorescent UV radiation, heat and
water in apparatus designed to simulate the weathering effects that occur when materials are exposed
in actual end-use environments to global solar radiation, or to solar radiation through window glass.
The specimens are exposed to fluorescent UV lamps under controlled environmental conditions
(temperature, humidity and/or water). Different types of fluorescent UV lamp can 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 4892-1.
NOTE Fluorescent UV lamp exposures for paints, varnishes and other coatings are described in ISO 11507.

Plastiques - Méthodes d'exposition à des sources lumineuses de laboratoire - Partie 3: Lampes fluorescentes UV (ISO 4892-3:2016)
ISO 4892-3:2016 spécifie des méthodes pour l'exposition d'éprouvettes à des rayonnements fluorescents UV, à la chaleur et à l'eau dans un appareillage conçu pour simuler les effets du vieillissement qui interviennent lorsque des matériaux sont exposés au rayonnement solaire total dans des environnements d'utilisation finale réelle, ou au rayonnement solaire à travers un vitrage de fenêtre.
Les éprouvettes sont exposées à des lampes fluorescentes UV dans des conditions environnementales maîtrisées (température, humidité et/ou teneur en eau). Différents types de lampes fluorescentes UV peuvent être utilisés pour satisfaire aux exigences relatives aux essais de différents matériaux.
La préparation des éprouvettes et l'évaluation des résultats sont traitées dans d'autres Normes internationales pour des matériaux spécifiques.
Des lignes directrices générales sont données dans l'ISO 4892‑1.
NOTE L'exposition aux lampes fluorescentes UV des peintures, vernis et autres revêtements est décrite dans l'ISO 11507.
Polimerni materiali - Metode izpostavljanja laboratorijskim virom svetlobe - 3. del: Fluorescentne UV-svetilke (ISO 4892-3:2016)
Ta del standarda ISO 4892 določa metode izpostavljenosti preskušancev fluorescenčnemu ultravijoličnemu sevanju, toploti in vodi v aparatu, ki je zasnovan za poustvaritev vremenskih vplivov, do katerih pride, ko so materiali v okolju, kjer se uporabljajo, izpostavljeni globalnemu sončnemu sevanju ali sončnemu sevanju, ki se filtrira skozi okensko steklo. Preskušanci so izpostavljeni fluorescenčnim ultravijoličnim sijalkam v okolju z nadzorovanimi okoljskimi pogoji (temperatura, vlažnost in/ali voda.) Za izpolnjevanje vseh zahtev pri preskušanju različnih materialov je mogoča uporaba različnih vrst fluorescenčnih ultravijoličnih sijalk.
Priprava preskušancev in vrednotenje rezultatov sta obravnavana v drugih mednarodnih standardih za določene materiale.
Splošna navodila so podana v standardu ISO 4892-1.
OPOMBA: Izpostavljenost fluorescenčnim ultravijoličnim sijalkam v povezavi z barvami, laki in drugimi premazi je opisana v standardu ISO 11507.

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 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
