This document gives guidelines and recommendations for the general principles of design appropriate to articles to be hot dip galvanized after fabrication (e.g. in accordance with ISO 1461) for the corrosion protection of, for example, articles that have been manufactured in accordance with EN 1090-2. This document does not apply to hot dip galvanized coatings applied to continuous wire or sheet (e.g. to EN 10346).

This document specifies the safety requirements and test methods for soft carriers without a framed support designed to carry one or two children hands free when attached to the carer’s torso. If the soft carrier has functions not covered in this document, reference can be made to the relevant European Standard. This document does not apply to garment or apparel carriers or carriers in the scope of prEN 13209-3:2026. This document does not cover baby carriers designed for children with special needs.

This document specifies a method for determining the dynamic surface tension of liquids based on the pressure in gas bubbles. The dynamic surface tension of solutions is influenced by surface-active molecules in the solution (often surfactants in water-based solutions). The surface tension is measured at a newly created interface depending on the age of this surface. This allows direct conclusions to be drawn about how quickly and strongly the surfactants in the solution reduce the surface tension of a new surface. The interface used to determine surface tension is renewed with each gas bubble. Due to the principle, very short measurement times in the millisecond range are possible, which makes the test method particularly suitable for surfactant-containing solutions of high concentration (significantly above the critical micelle concentration), e.g. in electroplating baths, cleaning baths, preferably low-viscosity Newtonian paints, inks. The sequence of air bubbles resulting from a gas volume flow enables continuous measurement without the sample having to flow through the measuring system. For the purpose of controlling surfactant concentration, surface tension is monitored at an appropriate, well-defined surface age.

This document defines test methods and criteria for distinguishing intrinsically biodegradable plastic materials from those that are persistent. Biodegradability is inferred from biodegradation tests conducted under aerobic conditions, i.e. under the conditions typically found in most natural habitats. Plastics that undergo ultimate biodegradation under aerobic conditions in a manner similar to natural polymer materials are defined as biodegradable plastics. This document describes a method for distinguishing between non-biodegradable plastics, which do not biodegrade even when environmental conditions are favourable for biodegradation (including aerobic conditions), and biodegradable plastics, i.e. those that biodegrade upon contact with active microorganisms when environmental conditions are favourable for biodegradation.

The aim is to demonstrate ultimate aerobic biodegradability of plastic materials, i.e. the intrinsic potential for conversion to carbon dioxide, water and biomass by aerobic microorganisms in an oxygen-rich environment, which is representative of most natural environments.

The potential for biodegradation should be verified using alternative tests and criteria, if a deposition in a permanent anaerobic environment (e.g. deep subsurface environments, wetlands and swamps, anoxic zones in oceans and lakes) is expected.

NOTE          Currently, there are no methodologies or criteria available to verify accumulation due to the lack of biodegradation of plastics in such anaerobic habitats.

The plastic materials identified as intrinsically biodegradable following this document can be used in the design of products with a high risk of dispersion whenever the use of biodegradable components is searched by the designer. Intrinsically non-biodegradable components are not susceptible to biodegradation and therefore cannot be removed from the environment by the action of micro-organisms. This factor tends to increase the residence time of products in the environment. In addition, their eventual degradation, mainly due to abiotic factors, results in persistent fragments (microplastics).

The test scheme described in this document is not specific to any particular application. Rather, it is a framework methodology that can be used in different industries to identify biodegradable plastics that can be used to make different types of products and for different applications. For the characterisation and environmental assessment of products placed on the market containing plastics identified as biodegradable according to this document, reference is made to the specific product standards, where available. This document only deals with the definition of intrinsic biodegradability of plastic materials, without defining the hazard of the products, which requires a specific assessment that is beyond the scope of this document. The rate of biodegradation of a plastic object as a function of environmental conditions cannot be determined from this document. Therefore, this document is not sufficient to carry out an analysis of the ecological risk associated with the dispersal of products, as this requires an assessment of the intrinsic hazard, of the environmental fate, in addition to the assessment of biodegradability.

The methodology described in this document does not apply to applications covered by mandatory regulations.

This document is applicable to self-propelled and pedestrian propelled manual and semi-manual industrial trucks as defined in ISO 5053 1:2020 including their load handling devices and attachments (hereafter referred to as trucks) intended for use in potentially explosive atmospheres. NOTE 1 Attachments mounted on the load carrier or on fork arms which are removable by the user are not considered to be a part of the truck. This document specifies supplementary technical requirements for the prevention of the ignition of an explosive atmosphere of flammable gases, vapours, mists or dusts by industrial trucks of equipment group II and equipment category 2G, 3G, 2D or 3D. NOTE 2 The relationship between an equipment category (hereafter referred to as category) and the corresponding zone (area classification) is shown in informative Annex B. This document does not apply to: — trucks of equipment group I; — trucks of equipment group II, equipment category 1; — trucks intended for use in potentially explosive atmospheres with hybrid mixtures; — protective systems. This document does not apply to trucks intended for use in potentially explosive atmospheres of carbon disulfide (CS2), carbon monoxide (CO) and/or ethylene oxide (C2H4O) due to the special properties of these gases.

This document specifies characteristics concerning the design and performance requirements together with type testing and on-site testing procedures especially for ducted filtration fume cupboards (DFFCs) not described in the other parts of EN 14175. Filters in DFFCs can be specific filters or a combination of filters dependent on the characteristics of the contaminants to be removed. This part of EN 14175 is related to and refers to other parts of EN 14175 regarding definitions, technologies, testing methodologies, design factors and functional aspects and is read in conjunction with these. This standard covers the specific layout version of ducted fume cupboards with integral filtration. These devices called ducted filtration fume cupboards can be designed to partially reuse filtered air for internal dilution. Therefore, the term “hybrid” fume cupboards is sometimes used. Fume cupboards with associated filters are considered as standard fume cupboards according EN 14175 1 to EN 14175 3. NOTE Their filter requirements, description and testing are listed in Annex A for information. The requirements for fume cupboards and filters for radioactive work are described in detail in EN 14175 8. Recirculatory filtration fume cabinets which return the filtered exhaust air back into the surrounding room are not part of this document but described in prEN 17242. DFFCs are not foreseen for work with pathogens. Appropriate microbiological cabinets are described in the EN 12469 series.

This part of EN 820 describes methods for determining the elastic moduli, specifically Young's modulus, shear modulus and Poisson's ratio, of advanced monolithic technical ceramics at temperatures above room temperature. The standard prescribes three alternative methods for determining some or all of these three parameters: A the determination of Young's modulus by static flexure of a thin beam in three- or four-point bending. B the determination of Young's modulus by forced longitudinal resonance, or Young's modulus, shear modulus and Poisson's ratio by forced flexural and torsional resonance, of a thin beam. C the determination of Young's modulus from the fundamental natural frequency of a struck bar (impulse excitation method). This part of EN 820 extends the above-defined room-temperature methods described in EN 843-2 to elevated temperatures. All the test methods assume the use of homogeneous test pieces of linear elastic materials. The test assumes that the test piece has isotropic elastic properties. At high porosity levels all of the methods can become inappropriate. The maximum grain size (see EN 623-3), excluding deliberately added whiskers, should be less than 10 % of the minimum dimension of the test piece. NOTE 1 Method C in EN 843-2 based on ultrasonic time of flight measurement has not been incorporated into this part of EN 820. Although the method is feasible to apply, it is specialised, and outside the capabilities of most laboratories. There are also severe restrictions on test piece geometries and methods of achieving pulse transmission. For these reasons this method has not been included in EN 820-5. NOTE 2 The upper temperature limit for this test depends on the properties of the test pieces, and can be limited by softening within the timescale of the test. In addition, for method A there can be limits defined by the choice of test jig construction materials.

This part of EN 843 specifies methods for determining the elastic moduli, specifically Young’s modulus, shear modulus and Poisson’s ratio, of advanced monolithic technical ceramics at room temperature. This European Standard prescribes four alternative methods for determining some or all of these three parameters: A The determination of Young’s modulus by static flexure of a thin beam in three- or four-point flexure. B The determination of Young’s modulus by forced longitudinal resonance, or Young’s modulus, shear modulus and Poisson’s ratio by forced flexural and torsional resonance, of a thin beam. C The determination of Young’s modulus, shear modulus and Poisson’s ratio from the time-of-flight of an ultrasonic pulse. D The determination of Young’s modulus from the fundamental natural frequency of a struck bar (impulse excitation method). All the test methods assume the use of homogeneous test pieces of linear elastic materials. NOTE 1 Not all ceramic materials are equally and linearly elastic in tension and compression, such as some porous materials and some piezoelectric materials. With the exception of Method C, the test assumes that the test piece has isotropic elastic properties. Method C may be used to determine the degree of anisotropy by testing in different orientations. NOTE 2 An ultrasonic method for dealing with anisotropic materials (ceramic matrix composites) can be found in ENV 14186 (see Bibliography). An alternative to Method D for isotropic materials using disc test pieces is given in Annex A. NOTE 3 At high porosity levels all of the methods except Method C can become inappropriate. The methods are only suitable for a maximum grain size (see EN 623-3), excluding deliberately added whiskers, of less than 10 % of the minimum dimension of the test piece. NOTE 4 The different methods given in this European Standard can produce slightly different results on the same material owing to differences between quasi-isothermal quasi-static an

It is the responsibility of the user of this document to establish appropriate health, safety and environmentally acceptable practices.

This document specifies a tensile testing procedure to evaluate the effect of a high-pressure test gas on the materials properties in comparisons to a high-pressure inert gas. It defines the required specimen geometries and the inner surface quality of hollow specimen of metallic materials, filled with a high-pressure-gas. The procedure is intended for screening and characterisation of metallic materials by assessing changes in mechanical properties resulting from various test gases, temperatures, or test pressures. Specific test conditions for tensile testing with high-pressure hydrogen gas are provided in normative Annex A.

This document provides guidelines on implementation and application of the concept of metrological traceability in measurements supporting the exploration, upgrading, transmission, distribution and use of natural gas, biogas, biomethane and other substitutes. The guidance aims at implementing requirements such as those laid down in ISO/IEC 17025:2017 6.5. The measurement of flow rate, composition, temperature, pressure and natural gas properties are covered. The document also addresses the metrological traceability of properties calculated from other quanties, such as pressure, temperature and composition.

This document describes how calibration, quality control and the evaluation of measurement uncertainty aid to establishing and underpinning the metrological traceability of measurement results. Requirements for the certification of traceable calibration gas mixtures and test gases are also addressed in this document.

Finally, the guidance extends to the measurement of the quantity and energy supplied or received, such as described in ISO 15112. Whereas it is recognised that the measurement of quantity and energy is in practice often implemented as a computational process using measurement data, this document takes the view that the purpose of the measurement is the quantity and energy, and that the measurements made in gas metering serve the purpose of providing metrologically traceable results as input for the measurement of quantity and energy.
