Plastics - Methods of exposure to solar radiation - Part 1: General guidance (ISO/DIS 877-1:2024)

ISO 877-1:2009 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 ISO 877. 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.

Plastiques - Méthodes d'exposition au rayonnement solaire - Partie 1: Lignes directrices générales (ISO/DIS 877-1:2024)

L'ISO 877-1:2009 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 l'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.
Elle spécifie également les méthodes de détermination de l'exposition énergétique.
Elle 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.

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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.+
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and expressions
related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT) see: www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 6, Ageing,
chemical and environmental resistance.
This second edition cancels and replaces the first edition (ISO 877-1:2009), which has been technically
revised.
The main changes are as follows:
— addition of new term and definition 3.1 "natural weathering";
— addition of a requirement for the area beneath and in the vicinity of racks in 5.1;
— addition of new NOTE 2 in 9.2 referring to ISO/TR 19032;
— addition of information to be included in the test report (Clause 11).
A list of all parts in the ISO 877 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user's national standards body. A
complete listing of these bodies can be found at www.iso.org/members.html.
