Plastics - Methods of exposure to solar radiation - Part 3: Intensified weathering using concentrated solar radiation (ISO 877-3:2018)

Plastics - Methods of exposure to solar radiation - Part 3: Intensified weathering using concentrated solar radiation (ISO 877-3:2018)

ISO 877-3:2018 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. 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.
General guidance concerning the scope of the ISO 877 series is given in ISO 877‑1.
NOTE       Additional information about solar concentrating exposures, including a partial list of standards in which they are specified, is given in the Bibliography.

Kunststoffe - Freibewitterung - Teil 3: Beschleunigte Bewitterung mit gebündelter Sonnenstrahlung (ISO 877-3:2018)

Dieses Dokument 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. 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.
Eine allgemeine Anleitung, die den Anwendungsbereich von ISO 877 betrifft, ist in ISO 877-1 angegeben.
ANMERKUNG 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 877-3:2018)

ISO 877-3:2018 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. Les concentrateurs réfléchissants utilisés dans ces essais d'exposition sont parfois désignés sous le nom de «miroirs de Fresnel» car, vu en coupe transversale, le jeu de miroirs utilisé pour concentrer le rayonnement solaire ressemble à la coupe transversale d'une lentille de Fresnel.
Des lignes directrices générales relatives au domaine d'application de la série ISO 877 sont données dans l'ISO 877‑1.
NOTE       Des informations supplémentaires concernant les essais d'exposition à un rayonnement solaire concentré, y compris une liste partielle des normes dans lesquelles ils sont spécifiés, sont données dans la Bibliographie.

Polimerni materiali - Metode izpostavitve vremenskim vplivom - 3. del: Pospešeni vremenski vpliv z uporabo koncentriranega sončnega sevanja (ISO 877-3:2018)

Ta dokument 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. 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.
Splošni napotki v zvezi s področjem uporabe skupine standardov ISO 877 so podani v standardu ISO 877-1.
OPOMBA: Več informacij o izpostavitvah koncentriranemu sončnemu žarčenju, vključno z nepopolnim seznamom standardov, v katerih so določene, je podanih v bibliografiji.

Plastics - Determination of thermal conductivity and thermal diffusivity - Part 4: Light flash method (ISO 22007-4:2024)
SIST EN ISO 22007-4:2024

This document specifies a method for the determination of the thermal diffusivity of a thin solid disc of plastics in the thickness direction by the light flash method. This method is based upon the measurement of the temperature rise at the rear face of the thin-disc specimen produced by a short energy pulse on the front face.
The method is applicable to homogeneous solid plastics as well as composites having an isotropic or orthotropic structure. In general, it covers materials having a thermal diffusivity, α, in the range 1 × 10−7 m2⋅s−1 < α < 1 × 10−4 m2⋅s−1. Measurements can be carried out in gaseous and vacuum environments over a temperature range from −100 °C to +400 °C.
NOTE          For inhomogeneous specimens, the measured values can be specimen thickness dependent.

EN ISO 8256:2023(Main)
Plastics - Determination of tensile-impact strength (ISO 8256:2023)
SIST EN ISO 8256:2024

1.1     This document specifies two methods (method A and method B) for the determination of the tensile-impact strength of plastics under defined conditions. The tests can be described as tensile tests at relatively high strain rates. These methods can be used for rigid materials (as defined in ISO 472), but are especially useful for materials too flexible or too thin to be tested with impact tests conforming to the ISO 179 series or ISO 180.
1.2     These methods are used for investigating the behaviour of specified specimens under specified impact velocities, and for estimating the brittleness or the toughness of specimens within the limitations inherent in the test conditions.
1.3     These methods are applicable both to specimens prepared from moulding materials and to specimens taken from finished or semi-finished products (for example mouldings, laminates, or extruded or cast sheets).
1.4     Results obtained by testing moulded specimens of different dimensions are not necessarily the same. Equally, it is possible that specimens cut from moulded products will not give the same results as specimens of the same dimensions moulded directly from the material. Test results obtained from specimens prepared from moulding compounds cannot be applied directly to mouldings of any given shape, because values may depend on the design of the moulding and the moulding conditions. Results obtained by method A and method B can or can not be comparable.
1.5     These methods are not suitable for use as a source of data for design calculations on components. Information on the typical behaviour of a material can be obtained, however, by testing different types of test specimen prepared under different conditions, and by testing at different temperatures. The two different methods are suitable for production control as well as for quality control.

Plastics - Determination of puncture impact behaviour of rigid plastics - Part 2: Instrumented impact testing (ISO 6603-2:2023)
SIST EN ISO 6603-2:2023

This document specifies a test method for the determination of puncture impact properties of rigid plastics, in the form of flat specimens, using instruments for measuring force and deflection. It is applicable if a force-deflection or force-time diagram, recorded at nominal constant striker velocity, is necessary for detailed characterization of the impact behaviour.
The test method is applicable to specimens with a thickness between 1 mm to 4 mm.
The method is suitable for use with the following types of material:
—    rigid thermoplastic moulding and extrusion materials, including filled, unfilled and reinforced compounds and sheets;
—    rigid thermosetting moulding and extrusion materials, including filled and reinforced compounds, sheets and laminates;
—    fibre-reinforced thermoset and thermoplastic composites incorporating unidirectional or multi-directional reinforcements such as mats, woven fabrics, woven rovings, chopped strands, combination and hybrid reinforcements, rovings, milled fibres and sheets made from pre-impregnated materials (prepregs).
The method is also applicable to specimens which are either moulded or machined from finished products, laminates and extruded or cast sheet.
The test results are comparable only if the conditions of preparation of the specimens, their dimensions and surfaces as well as the test conditions are the same. In particular, results determined on specimens of different thickness cannot be compared with one another (see Annex E). Comprehensive evaluation of the reaction to impact stress can be obtained by determinations made as a function of impact velocity and temperature for different material variables, such as crystallinity and moisture content.
The impact behaviour of finished products cannot be predicted directly from this test, but specimens may be taken from finished products (see above) for tests by this method.
Test data developed by this method is not intended to be used for design calculations. However, information on the typical behaviour of the material can be obtained by testing at different temperatures and impact velocities (see Annex D) by varying the thickness (see Annex E) and by testing specimens prepared under different conditions.
It is not the purpose of this document to give an interpretation of the mechanism occurring on every particular point of the force-deflection diagram. These interpretations are a task for scientific research.
