This document specifies two methods for evaluating the melting behaviour of semi-crystalline
polymers.
a) Method A: Capillary tube
This method is based on the changes in shape of the polymer. It is applicable to all semi-crystalline
polymers and their compounds.
NOTE 1 Method A can also be useful for the evaluation of the softening of non-crystalline solids.
b) Method B: Polarizing microscope
This method is based on changes in the optical properties of the polymer. It is applicable to polymers
containing a birefringent crystalline phase. It might not be suitable for plastics compounds containing
pigments and/or other additives which can interfere with the birefringence of the polymeric crystalline
zone.
NOTE 2 Another method applicable to semi-crystalline polymers is described in ISO 11357-3.

This document specifies two test methods for determining the refractive index of plastics, namely:
—    Method A: a refractometric method for measuring the refractive index of moulded parts, cast or extruded sheet or film, by means of a refractometer. It is applicable not only to isotropic transparent, translucent, coloured or opaque materials but also to anisotropic materials.
—    Method B: an immersion method (making use of the Becke line phenomenon) for determining the refractive index of powdered or granulated transparent materials by means of a microscope. Monochromatic light, in general, is used to avoid dispersion effects.
NOTE      The refractive index is a fundamental property which can be used for checking purity and composition, for the identification of materials and for the design of optical parts. The change in refractive index with temperature can give an indication of transition points of materials.

This document specifies the requirements for the laboratory testing of the resistivity of specially
prepared specimens of plastics rendered conductive by the inclusion of conductive fillers or suitable
modification of the structure. The test is applicable to materials of resistivity less than 106 Ω⋅cm
(104 Ω⋅m).
The result is not strictly a volume resistivity, because of surface conduction, but the effects of the latter
are generally negligible.

This document specifies test methods for the determination of the degree of disintegration of plastic materials exposed to marine habitats under real field conditions.
The marine areas under investigation are the sandy sublittoral and the sandy eulittoral zone where plastic materials can either be placed intentionally (e.g. biodegradable fishing nets) or end up as litter due to irresponsible human behaviour. This depends on their physical characteristics, form and size of the materials, and on water currents and tidal movements.
This document specifies the general requirements of the apparatus, and the procedures for using the test methods described.
The determination of the level of disintegration of plastic materials exposed to pelagic zones such as the sea surface or the water column above the seafloor are not within the scope of this document.
This document is not suitable for the assessment of disintegration caused by heat or light exposure.
The described field test is a disintegration test and not a biodegradation test. Therefore, it cannot be used for demonstrating biodegradation or for making unqualified claims such as "biodegradable in marine environment" and similar.

This document specifies a laboratory test method to determine the degree and rate of aerobic biodegradation level of plastic materials. This test method can also be applied to other materials.
Biodegradation is determined by measuring the CO2 evolved by the plastic material when exposed to marine sediments sampled from a sandy tidal zone and kept wet with salt-water under laboratory conditions.
This test method is a simulation under laboratory conditions of the habitat found in sandy tidal zone that, in marine science, is called eulittoral zone.
The conditions described in this document might not always correspond to the optimum conditions for the maximum degree of biodegradation to occur.
Deviations from the test conditions described in this document are justified in the test report.

This document specifies test methods and criteria for showing intrinsic biodegradability in marine environments of virgin plastic materials and polymers without any preliminary environmental exposure or pre-treatment.
Test methods applied in this document are carried out at temperatures in the mesophilic range under aerobic conditions and are aimed to show ultimate biodegradability, i.e. conversion into carbon dioxide, water and biomass.
This document neither assesses the constituents, such as regulated metals or substances hazardous to the environment, nor potential ecotoxic effects but intrinsic biodegradability only. These aspects will be considered in a separate standard covering the overall environmental impact of products intentionally or accidentally released in the marine environment.
This document does not cover the performance of products made from biodegradable plastic materials and biodegradable polymers. Lifetime and biodegradation rates in the sea of products made with biodegradable plastic materials are generally affected by the specific environmental conditions and by thickness and shape.
Although results might indicate that the tested plastic materials and polymers biodegrade under the specified test conditions at a certain rate, the results of any laboratory exposure cannot be directly extrapolated to marine environments at the actual site of use or leakage.
This document is not applicable for "marine biodegradable" claims of biodegradable plastic materials. For such purpose, see relevant product standards, if available.
The testing scheme specified in this document does not provide sufficient information for determining the specific biodegradation rate (i.e. the rate per available surface area) of the material under testing. For such purpose, see relevant standards about specific biodegradation rate, if available.

This document specifies a method, by measuring the amount of carbon dioxide evolved, for the
determination of the degree of aerobic biodegradability of plastic materials, including those containing
formulation additives. The test material is exposed in a synthetic medium under standardized
laboratory conditions to an inoculum from activated sludge under aerobic conditions.
The conditions used in this document do not necessarily correspond to the optimum conditions allowing
maximum biodegradation to occur, but this test method is designed to measure the biodegradation of
plastic materials and give an indication of their potential biodegradability.
The method enables the assessment of the biodegradation to be improved by calculating a carbon
balance (optional, see Annex C).
The method applies to the following materials:
— natural and/or synthetic polymers, copolymers or mixtures thereof;
— plastic materials which contain additives such as plasticizers, colorants or other compounds;
— water-soluble polymers;
— materials which, under the test conditions, do not inhibit the microorganisms present in the
inoculum. Inhibitory effects can be determined using an inhibition control or by another appropriate
method (see, for example, ISO 8192[1]). If the test material is inhibitory to the inoculum, a lower test
concentration, another inoculum or a pre-exposed inoculum can be used.

in a pilot-scale aerobic composting test under defined conditions. It forms part of an overall scheme for
the evaluation of the industrial compostability of plastics as outlined in ISO 17088.
The test method laid down in this document is also used to determine the influence of the test material
on the composting process and the quality of the compost obtained. This test method cannot be used to
determine the aerobic biodegradability of a test material.
NOTE Other methods are available for this test (for example, see ISO 14851, ISO 14852 or ISO 14855-1 and
ISO 14855-2).

This document specifies procedures and requirements for plastics, and products made from plastics, that are suitable for recovery through organic recycling. The four following aspects are addressed: a) disintegration during composting; b) ultimate aerobic biodegradation; c) no adverse effects of compost on terrestrial organisms; d) control of constituents. These four aspects are suitable to assess the effects on the industrial composting process. This document is intended to be used as the basis for systems of labelling and claims for compostable plastics materials and products. This document does not provide information on requirements for the biodegradability of plastics which end up in the environment as litter. It is also not applicable to biological treatment undertaken in small installations by householders. NOTE 1   The recovery of compostable plastics through composting can be carried out under the conditions found in well-managed industrial composting processes, where the temperature, water content, aerobic conditions, carbon/nitrogen ratio and processing conditions are optimized. Such conditions are generally obtained in industrial and municipal composting plants. Under these conditions, compostable plastics disintegrate and biodegrade at rates comparable to yard trimmings, kraft paper bags and food scraps. NOTE 2   “Compostable” or “compostable in municipal and industrial composting facilities” are expressions considered to be equivalent to organically recyclable for the purposes of this document.

This document specifies the general principles of a method for determining the transient extensional viscosity of polymer melts. The procedure details the measurement of polymer melt specimens stretched uniaxially under conditions of constant strain rate and constant temperature. The method is capable of measuring the transient extensional viscosity of polymer melts at Hencky strain rates typically in the range 0,01 s–1 to 1 s–1, at Hencky strains up to approximately 4 and at temperatures up to approximately 250 °C (see NOTEs 1 and 2). It is suitable for measuring transient extensional viscosity values typically in the range from approximately 104 Pa⋅s to 107 Pa⋅s (see NOTE 3). NOTE 1  Hencky strains and strain rates are used (see Clause 3). NOTE 2  Values of strain, strain rate and temperature outside these limiting values can be attained. NOTE 3  The operating limit of an instrument, in terms of the lowest transient extensional viscosity values that can be measured, is due to a combination of factors, including the ability of the specimen to maintain its shape during testing and the resolution of the instrument.

This document defines a test method used to determine the degree of disintegration of plastic materials in a pilot-scale aerobic composting test under defined conditions. It forms part of an overall scheme for the evaluation of the industrial compostability of plastics as outlined in ISO 17088. The test method laid down in this document is also used to determine the influence of the test material on the composting process and the quality of the compost obtained. This test method cannot be used to determine the aerobic biodegradability of a test material. NOTE Other methods are available for this test (for example, see ISO 14851, ISO 14852 or ISO 14855-1 and ISO 14855-2).

This document specifies methods for determining the fluidity of plastics melts subjected to shear stresses at rates and temperatures approximating to those arising in plastics processing. Testing plastics melts in accordance with these methods is of great importance since the fluidity of plastics melts is generally not dependent solely on temperature, but also on other parameters; in particular shear rate and shear stress. The methods described in this document are useful for determining melt viscosities from 10 Pa∙s to 107 Pa∙s, depending on the measurement range of the pressure and/or force transducer and the mechanical and physical characteristics of the rheometer. The shear rates occurring in extrusion rheometers range from 1 s−1 to 106 s−1. Elongational effects at the die entrance cause extrudate swelling at the die exit. Methods for assessing extrudate swelling have also been included. The rheological techniques described are not limited to the characterization of wall-adhering thermoplastics melts only; for example, thermoplastics exhibiting "slip" effects[1][2] and thermosetting plastics can be included. However, the methods used for determining the shear rate and shear viscosity are invalid for materials which are not wall-adhering. Nevertheless, this document can be used to characterize the rheological behaviour of such fluids for a given geometry.

This document specifies the characteristics of non-adiabatic fast differential scanning calorimeters, also covered by the general abbreviation FSC having an open specimen geometry in which specimens are placed directly onto active measurement areas of chip sensors based on Micro-Electro-Mechanical Systems (MEMS) membrane technology, without encapsulation in closed crucibles and ovens. Due to the open specimen geometry, this document is applicable to very small specimens having masses of not greater than 1 µg only. The occurrence of high temperature gradients during measurements can be prevented by keeping specimen thicknesses as small as possible. The use of very low specimen masses enables achievement of very high scanning rates in the order of several thousand K/s, both in heating and cooling mode whereby lower specimen masses and thicknesses allow higher heating and cooling rates. Typically, low scanning rates of FSC overlap with high scanning rates of conventional DSC covered by ISO 11357‑1, thus enabling connection to conventional DSC results. NOTE 1 Due to the sensor layout FSC is also called chip calorimetry. NOTE 2 FSC stands for Fast Scanning Calorimetry but also for Fast Scanning Calorimeter. In practice from the context the choice can be made quite easily. FSC is suitable for thermal analysis of fast kinetic effects of polymers, polymer blends and composites, such as: — thermoplastics (polymers, moulding compounds and other moulding materials, with or without fillers, fibres or reinforcements); — thermosets (uncured or cured materials, with or without fillers, fibres or reinforcements); — elastomers (with or without fillers, fibres or reinforcements). This document specifies methods for qualitative and quantitative analysis of fast physical and chemical processes showing changes in heat flow rate. This includes measurement of characteristic temperatures as well as caloric values of both, solid and liquid materials. This document is particularly applicable for the observation of fast kinetics of thermal effects such as: — physical transitions (glass transition, phase transitions such as melting and crystallization, polymorphic transitions, etc.); — metastability and related processes like reorganization, (re)crystallization, annealing, ageing, amorphization; — chemical reactions (hydration, oxidation, polymerisation, crosslinking and curing of elastomers and thermosets, decomposition, etc.); — isothermal measurements of fast crystallising systems or chemical reactions. It is also applicable for the determination of heat capacity and related changes of thermodynamic functions. FSC provides a technique to analyse material behaviour at similarly high heating or cooling rates used in industrial polymer processing. FSC can also enable separation of overlapping thermal effects with different kinetics such as: — melting and decomposition: higher heating rates can shift decomposition to higher temperatures and allow unperturbed measurement of melting; — glass transition and cold crystallisation of polymers: higher heating rates can suppress cold crystallisation resulting in unperturbed measurement of glass transition as a function of cooling / heating rates; — reorganisation of amorphous or semi-crystalline polymers upon cooling and heating: depending on the cooling rate used specimens with different crystallinities can be generated and their reorganisation upon heating analysed using different scanning rates. This document establishes general aspects of FSC, such as the principle and the apparatus, sampling, calibration and general aspects of the procedure and test report.
