Plastics - Methods of exposure to solar radiation - Part 1: General guidance (ISO 877-1:2025)
This document provides information and general guidance on the selection and use of the methods of exposure to solar radiation described in detail in subsequent parts of the ISO 877 series. These methods of exposure to solar radiation are applicable to plastics materials of all kinds as well as to products and portions of products.
It also specifies methods for determining radiant exposure.
It does not include direct weathering using black-box test fixtures, which simulate higher end-use temperatures in some applications.
NOTE ASTM G7 and ASTM D4141 describe black-box exposure tests.
Kunststoffe - Freibewitterung - Teil 1: Allgemeine Anleitung (ISO 877-1:2025)
Dieses Dokument stellt Informationen und eine allgemeine Anleitung zur Auswahl und Anwendung der Verfahren für die Beanspruchung durch die Sonnenstrahlung, die in den nachfolgenden Teilen der Normenreihe ISO 877 ausführlich beschrieben sind, zur Verfügung. Diese Verfahren für die Beanspruchung durch die Sonnenstrahlung sind auf Kunststoff-Werkstoffe aller Art sowie auf Produkte und Produktteile anwendbar.
Darüber hinaus werden in diesem Dokument Verfahren zur Bestimmung der Bestrahlung festgelegt.
In diesem Dokument ist die direkte Bewitterung unter Anwendung der Black-Box-Prüfvorrichtungen, die höhere Gebrauchstemperaturen bei manchen Anwendungen simuliert, nicht enthalten.
ANMERKUNG Beanspruchungsprüfungen unter Anwendung von Black-Box-Prüfvorrichtungen sind in ASTM G7 [1] und ASTM D4141 [2] beschrieben.
Plastiques - Méthodes d'exposition au rayonnement solaire - Partie 1: Lignes directrices générales (ISO 877-1:2025)
Le présent document fournit des informations et des lignes directrices générales concernant le choix et l’utilisation des méthodes d’exposition au rayonnement solaire, décrites de manière détaillée dans les parties suivantes de la série ISO 877. Ces méthodes d’exposition au rayonnement solaire sont applicables à tous les types de plastiques ainsi qu’aux produits et parties de produits.
Il spécifie également les méthodes de détermination de l’exposition énergétique.
Il n’inclut pas l’exposition directe aux intempéries au moyen d’installations d’essai d’exposition en boîte noire, qui simule des températures finales plus élevées dans certaines applications.
NOTE L’ASTM G7 et l’ASTM D4141 décrivent les essais d’exposition en boîte noire.

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).
