Plastics - Methods of exposure to laboratory light sources - Part 3: Fluorescent UV lamps (ISO/FDIS 4892-3:2024)

ISO 4892-3:2016 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/FDIS 4892-3:2024)

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.

EN ISO 22007-1:2024

This document describes the background to methods for the determination of the thermal conductivity
and thermal diffusivity of polymeric materials. Different techniques are available for these measurements
and some can be better suited than others for a particular type, state and form of material. This document
provides a broad overview of these techniques. Standards specific to these techniques, as referenced in this
document, are used to carry out the actual test method.

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

Plastics - Test specimens (ISO 20753:2023)
EN ISO 20753:2023

This document specifies dimensional requirements relating to test specimens prepared from plastics materials intended for processing by moulding, as well as to test specimens prepared by machining from sheets or shaped articles. It compiles the designations and dimensions of test specimens used for the acquisition of comparable data and also of other frequently used specimens.
The following types of test specimen are specified:
a) Type A1 and type A2 specimens (1 = injection moulded, 2 = machined from a sheet or shaped article)
These are tensile test specimens from which, with simple machining, specimens for a variety of other tests can be taken (see Annex A).
The type A1 specimen is a multipurpose test specimen. The principal advantage of a multipurpose test specimen is that it allows all the test methods mentioned in Annex A to be carried out by all test laboratories on the basis of comparable mouldings. Consequently, the properties measured are coherent as all are measured using similar specimens prepared in the same way. In other words, it can be expected that test results for a given set of specimens will not vary appreciably due to unintentionally different moulding conditions. On the other hand, if desired, the influence of moulding conditions and/or different states of the specimens can be assessed without difficulty for all of the properties measured.
Also described are reduced-scale test specimens designated type Axy, where x is the number indicating the method of specimen preparation (1 = injection moulded, 2 = machined from a sheet or shaped article) and y is a number indicating the scale factor (1:y). These can be used e.g. when full-sized test specimens are not convenient or when sample material exists in small quantities only.
b) Type B specimens
These are bar specimens which can be directly moulded or can be machined from the central section of type A1 specimens or from sheets or shaped articles.
c) Type C specimens
These are small tensile test specimens which can be directly moulded or machined, e.g. from plates (Type D or type F specimens), from the central section of type A1 specimens or from sheets or shaped articles.
d) Type D1 and type D2 specimens
These are square plates of thickness 1 mm and 2 mm, respectively.
e) Type F specimens
These are rectangular plates intended for use in the analysis of mechanical anisotropy.
If a particular type of test specimen is not mentioned in this document, this does not mean that there is any intention to exclude the use of the specimen. Additional specimen types can be added in future if they are commonly used.

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

ISO 8256:2004 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 ISO 179 or ISO 180.
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.
These methods are applicable both to specimens prepared from moulding materials and to specimens taken from finished or semi-finished products (for example mouldings, films, laminates, or extruded or cast sheets).
Results obtained by testing moulded specimens of different dimensions may not necessarily be the same. Equally, specimens cut from moulded products may 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 may or may not be comparable.
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 Charpy impact properties - Part 1: Non-instrumented impact test (ISO 179-1:2023)
EN ISO 179-1:2023

ISO 179-1:2010 specifies a method for determining the Charpy impact strength of plastics under defined conditions. A number of different types of specimen and test configurations are defined. Different test parameters are specified according to the type of material, the type of test specimen and the type of notch.
The method can be used to investigate the behaviour of specified types of specimen under the impact conditions defined and for estimating the brittleness or toughness of specimens within the limitations inherent in the test conditions. It can also be used for the determination of comparative data from similar types of material.
The method has a greater range of applicability than that given in ISO 180 (Izod impact testing) and is more suitable for the testing of materials showing interlaminar shear fracture or of materials exhibiting surface effects due to environmental factors.
The method is suitable for use with the following range of materials:
rigid thermoplastic moulding and extrusion materials (including filled and reinforced compounds in addition to unfilled types) and rigid thermoplastics sheets;
rigid thermosetting moulding materials (including filled and reinforced compounds) and rigid thermosetting sheets (including laminates);
fibre-reinforced thermosetting and thermoplastic composites incorporating unidirectional or multi-directional reinforcements (such as mats, woven fabrics, woven rovings, chopped strands, combination and hybrid reinforcements, rovings and milled fibres) or incorporating sheets made from pre-impregnated materials (prepregs), including filled compounds;
thermotropic liquid-crystal polymers.
