Plastics - Determination of the ultimate anaerobic biodegradation under high-solids anaerobic-digestion conditions - Method by analysis of released biogas (ISO 15985:2014)

Plastics - Determination of the ultimate anaerobic biodegradation under high-solids anaerobic-digestion conditions - Method by analysis of released biogas (ISO 15985:2014)

ISO 15985:2014 specifies a method for the evaluation of the ultimate anaerobic biodegradability of plastics based on organic compounds under high-solids anaerobic-digestion conditions by measurement of evolved biogas at the end of the test. This method is designed to simulate typical anaerobic digestion conditions for the organic fraction of mixed municipal solid waste. The test material is exposed in a laboratory test to a methanogenic inoculum derived from anaerobic digesters operating only on pretreated household waste. The anaerobic decomposition takes place under high-solids (more than 20 % total solids) and static non-mixed conditions. The test method is designed to yield the percentage of carbon in the test material and its rate of conversion to evolved carbon dioxide and methane (biogas).

Plastiques - Évaluation de la biodégradation anaérobie ultime dans des conditions de digestion anaérobie à teneur élevée en solides - Méthode par analyse du biogaz libéré (ISO 15985:2014)

L'ISO 15985:2014 spécifie une méthode pour l'évaluation de la biodégradabilité anaérobie ultime des plastiques basée sur des composés organiques dans des conditions de digestion anaérobie à teneur élevée en solides, par mesurage du biogaz libéré à la fin de l'essai. La présente méthode est conçue pour simuler les conditions de digestion anaérobie caractéristiques de la fraction organique des déchets municipaux solides mixtes. Le matériau d'essai est exposé, lors d'un essai en laboratoire, à un inoculum méthanogène dérivé de digesteurs anaérobies fonctionnant uniquement avec des déchets ménagers prétraités. La décomposition anaérobie a lieu dans des conditions à teneur élevée en solides (plus de 20 % de matières solides totales) et statiques non mixtes. La méthode d'essai a pour objet de permettre d'obtenir le pourcentage de carbone contenu dans le matériau d'essai et son taux de conversion en dioxyde de carbone et en méthane (biogaz) libérés.
Les conditions décrites dans l'ISO 15985:2014 ne correspondent pas nécessairement aux conditions optimales permettant d'obtenir le taux maximal de biodégradation.

Polimerni materiali - Ugotavljanje dokončne anaerobne biodegradacije v pogojih anaerobne razgradnje pri visokem deležu trdnih snovi - Metoda z analizo sproščenega bioplina (ISO 15985:2014)

Standard ISO 15985:2014 določa metodo za ocenjevanje končne anaerobne biorazgradljivosti polimernih materialov, ki temeljijo na organskih sestavinah, pod pogoji anaerobne razgradnje pri visokem deležu trdnih snovi z merjenjem količine sproščenega bioplina na koncu preskusa. Ta metoda je zasnovana za simulacijo značilnih pogojev anaerobne razgradnje organskega deleža mešanih trdnih komunalnih odpadkov. Preskusni material je v laboratorijskem preskusu izpostavljen metanogenemu inokulumu, pridobljenemu iz anaerobnih gnilišč izključno za predhodno obdelane gospodinjske odpadke. Anaerobna razgradnja se odvija pri visokem deležu trdnih snovi (več kot 20 % trdnih snovi) in pri statičnih pogojih, pri čemer se odpadki ne mešajo. Preskusna metoda je zasnovana za prikaz deleža ogljika v preskusnem materialu ter njegove hitrosti pretvorbe v sproščeni ogljikov dioksid in metan (bioplin).

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.
