Plastics - Methods of exposure to solar radiation - Part 3: Intensified weathering using concentrated solar radiation (ISO 877-3:2009)

ISO 877-3:2009 specifies a method for exposing plastics to concentrated solar radiation using reflecting concentrators to accelerate the weathering processes. The purpose is to assess property changes produced after specified stages of such exposures.

Kunststoffe - Freibewitterung - Teil 3: Beschleunigte Bewitterung mit gebündelter Sonnenstrahlung (ISO 877-3:2009)

Dieser Teil von ISO 877 legt ein Verfahren für die Beanspruchung von Kunststoffen mit gebündelter Sonnen-
strahlung unter Verwendung von Fresnel-Sammelspiegeln zur Beschleunigung der Bewitterungsvorgänge fest. Das Ziel ist es, die Eigenschaftsänderungen, die nach bestimmten Stufen derartiger Beanspruchungen eintreten, zu beurteilen. Eine allgemeine Anleitung, die den Anwendungsbereich von ISO 877 betrifft, ist in ISO 877-1:2009, Abschnitt 1, angegeben. Die bei diesen Beanspruchungen verwendeten Sammelspiegel werden mitunter als Fresnel-Sammelspiegel bezeichnet, weil der Querschnitt der Spiegelanordnung, die zur Bündelung der Sonnenstrahlung angewendet wird, dem Querschnitt einer Fresnel-Linse ähnelt.
Zu zusätzlichen Informationen über Beanspruchungen mit gebündelter Sonnenstrahlung einschließlich einer Teilliste von Normen, in denen diese festgelegt sind, siehe Literaturhinweise.

Plastiques - Méthodes d'exposition au rayonnement solaire - Partie 3: Exposition intensifiée par rayonnement solaire concentré (ISO 877-3:2009)

L'ISO 877-3:2009 spécifie une méthode d'exposition des plastiques à un rayonnement solaire concentré à l'aide de concentrateurs réfléchissants pour accélérer le processus d'exposition aux intempéries. L'objectif consiste à évaluer les changements produits après des phases d'exposition spécifiées.

Polimerni materiali - Metode izpostavitve vremenskim vplivom - 3. del: Pospešeni vremenski vpliv z uporabo koncentriranega sončnega žarčenja (ISO 877-3:2009)

Ta del standarda ISO 877 določa metodo za izpostavitev plastike koncentriranemu sončnemu žarčenju z odbojnimi solarnimi koncentratorji za pospešitev vremenskega vpliva. Njegov namen je oceniti spremembe lastnosti, do katerih pride po določenih stopnjah take izpostavitve. Splošni napotki v zvezi s področjem uporabe standarda ISO 877 so podani v točki 1 standarda ISO 877-1:2009. Za odbojne koncentratorje, ki se uporabljajo pri teh izpostavitvah, se včasih uporablja izraz »Fresnelovi kolektorji«, ker je razporeditev ogledal, ki se uporablja za koncentracijo sončnega žarčenja, v prerezu podobna Fresnelovi leči. Za več informacij o izpostavitvah koncentriranemu sončnemu žarčenju, vključno z nepopolnim seznamom standardov, v katerih so določene, glejte bibliografijo.

ISO 877-3:2009(E)
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.
ISO 877-3 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 6, Ageing, chemical
and environmental resistance.
Together with the other parts (see below), it cancels and replaces ISO 877:1994, which has been technically
revised.
ISO 877 consists of the following parts, under the general title Plastics — Methods of exposure to solar
radiation:
⎯ Part 1: General guidance
⎯ Part 2: Direct weathering and exposure behind window glass
⎯ Part 3: Intensified weathering using concentrated solar radiation

INTERNATIONAL STANDARD ISO 877-3:2009(E)

Plastics — Methods of exposure to solar radiation —
Part 3:
Intensified weathering using concentrated solar radiation
1 Scope
This part of ISO 877 specifies a method for exposing plastics to concentrated solar radiation using reflecting
concentrators to accelerate the weathering processes. The purpose is to assess property changes produced
after specified stages of such exposures. General guidance concerning the scope of ISO 877 is given in
ISO 877-1:2009, Clause 1. The reflecting concentrators used in these exposures are sometimes referred to as
“Fresnel reflectors” because in cross-section the array of mirrors used to concentrate the solar radiation
resembles the cross-section of a Fresnel lens.
For additional information about solar concentrating exposures, including a partial list of standards in which
they are specified, refer to the Bibliography.

4 Apparatus
4.1 General requirements
Refer to ISO 877-1:2009, Subclause 5.1, for general requirements.
All requirements for the solar concentrating device, operation of the device and measurement of the solar
radiation within the specimen exposure area shall be in accordance with ASTM G 90. See Figures 1 and 2 for
schematic diagrams of the two types of test apparatus.
