This document establishes a classification for phenolic and aminoplastic polycondensation adhesives classified according to EN 301, one component polyurethane adhesives classified according to EN 15425 and emulsion polymer isocyanate adhesives classified according to EN 16254, according to their suitability for use for load-bearing timber structures made of selected hardwood species (group A) in defined climatic exposure conditions; it specifies performance requirements for such adhesives for the factory manufacture or factory-like manufacturing conditions of load-bearing timber structures made of selected hardwood species only, with no specific high shear strength classification. NOTE An adhesive with high shear strength classification is needed when the declared characteristic shear strength of the glued laminated product is above 3,5 N/mm2, which is the declared characteristic shear strength of glulam made of softwoods according to EN 14080:2013 Table 4. See prEN 18307-3 requirements in this case. It also classifies aminoplastic adhesive systems being used with a range of hardener dosage, and one component polyurethane adhesive product lines where all the products within the line have the same chemical composition except for a different amount of catalyst. This document only specifies the performance of an adhesive for use in an environment corresponding to the defined conditions. The performance requirements of this document are applicable to the adhesive only, not to the manufacturing timber products. This document does not cover the performance of adhesives for on-site gluing (except for factory-like conditions) nor the production of wood-based panels, except solid wood panels, or modified and stabilized wood with considerably reduced swelling and shrinkage properties, e.g. such as acetylated wood, heat treated wood and polymer impregnated wood. It also does not cover preservative treated wood. This document is primarily intended for use by adhesive manufacturers and for use in timber products made of selected hardwood species bonded with adhesives, to assess or control the quality of adhesives. The requirements apply to the type testing of the adhesives. Production control activities are outside the scope of this document. Adhesives meeting the requirements of this document are adequate for use in a load-bearing timber products made of selected hardwood species, provided that the bonding process has been carried out according to an appropriate product standard. Selected hardwood species covered by this document are listed in FprCEN/TS XXX , group A. FprCEN/TS XXX also specifies nominal physical properties of the mentioned species that are used for testing according to this document.

Vandens kokybė. Plutonis ir neptūnis. Bandymas ICP-MS metodu (ISO/DIS 20899:2026)

This document specifies methods to determine the 239Pu, 240Pu, 241Pu and 237Np by inductively coupled plasma mass spectrometry (ICP-MS). The mass concentrations obtained can be converted into activity concentrations. Due to its relatively short half-life and 238U isobaric interference, 238Pu can hardly be measured by this method. To quantify 238Pu isotope by mass spectrometry, other techniques can be used (ICP-MS with collision-reaction cell, ICP-MS/MS with collision-reaction cell or chemical separation). Alpha spectrometry measurement, as described in ISO 13167,[8] is currently used[9]. The method is applicable to test samples of supply/drinking water, rainwater, surface and ground water, marine water, as well as cooling water, industrial water, domestic, and industrial wastewater after proper sampling and handling, and test sample preparation. A chemical separation of Np and Pu, with quantitative removal of all other elements (including uranium, americium, etc.) is mandatory, given all the potential interferences that may bias the measurement or lead to false positives. Chemical separations can eliminate most of the 238U. However, use of reagents, glassware, and atmosphere for the chemical separation, will also add 238U to the samples and prevent measurement of 238Pu. The limit of detection depends on the sample volume, the instrument used, the background count rate, the detection efficiency, the counting time, and the chemical yield. The detection limit of the method described in this document, using currently available ICP-MS apparatus, is approximately 1 mBq·l-1 for 239Pu, 240Pu, 237Np and 1 Bq·l-1 for 241Pu, which is lower or of the same order of magnitude than the WHO criteria for safe consumption of drinking water (1 mBq·l-1 for 239Pu, 240Pu, 237Np and 10 Bq·l-1 for 241Pu[4]).This method covers the measurement of those radionuclides in water at activity concentrations between approximately[10][11]: — 1 mBq·l−1 to 5 Bq·l−1 for 239Pu, 240Pu and 237Np; — 1 Bq·l−1 to 5 Bq·l−1 for 241Pu. Samples with higher activity concentrations than 5 Bq·l−1 can be measured if a dilution is performed. The higher is the concentration factor, the lower are the LD and LQ expressed in Bq/L of water. A preconcentration is especially useful for the quantification of 241Pu that is usually the less abundant isotope of plutonium. The method described in this document is applicable in the event of an emergency situation. Filtration of the test sample is necessary. The analysis of 239Pu, 240Pu, 241Pu and 237Np adsorbed to suspended matter is not covered by this method. The analysis of the insoluble fraction requires a mineralization step that is not covered by this document. In this case, the measurement is performed separately on each phase or the total phase. It is the user’s responsibility to ensure the validity of this test method for the water samples tested.

Plastikai. Lankstomųjų savybių nustatymas (ISO/DIS 178:2026)

This document specifies a method for determining the flexural properties of rigid and semi-rigid plastics under defined conditions. A preferred test specimen is defined, but parameters are included for alternative specimen sizes for use where appropriate. A range of test speeds is included. The method is used to investigate the flexural behaviour of the test specimens and to determine the flexural strength, flexural modulus and other aspects of the flexural stress/strain relationship under the conditions defined. It applies to a freely supported beam, loaded at midspan (three-point loading test). The method is suitable for use with the following range of materials: — thermoplastic moulding, extrusion and casting materials, including filled and reinforced compounds in addition to unfilled types; rigid thermoplastics sheets; — thermosetting moulding materials, including filled and reinforced compounds; thermosetting sheets. In agreement with ISO 10350-1[5] and ISO 10350-2,[6] this document applies to fibre-reinforced compounds with fibre lengths ≤7,5 mm prior to processing. For long-fibre-reinforced materials (laminates) with fibre lengths >7,5 mm, see ISO 14125[7]. The method is not normally suitable for use with rigid cellular materials or sandwich structures containing cellular material. In such cases, ISO 1209-1[3] and/or ISO 1209-2[4] can be used. NOTE 1 For certain types of textile-fibre-reinforced plastic, a four-point bending test is used. This is described in ISO 14125. The method is performed using specimens which can be either moulded to the specified dimensions, machined from the central section of a standard multipurpose test specimen (see ISO 20753) or machined from finished or semi-finished products, such as mouldings, laminates, or extruded or cast sheet. The method specifies the preferred dimensions for the test specimen. Tests which are carried out on specimens of different dimensions, or on specimens which are prepared under different conditions, can produce results which are not comparable. Other factors, such as the test speed and the conditioning of the specimens, can also influence the results. NOTE 2 Especially for injection moulded semi-crystalline polymers, the thickness of the oriented skin layer, which is dependent on the moulding conditions, also affects the flexural properties. The method is not suitable for the determination of design parameters but can be used in materials testing and as a quality control test.
