Branduolinio kuro technologija. Urano nustatymas tirpaluose, urano heksafluoride ir kietosiose medžiagose. 1 dalis. Redukavimo geležimi(II) ir oksidavimo kalio dichromatu titrimetrinės analizės metodas (ISO 7097-1:2025)

This document describes an analytical method for the determination of uranium in samples from pure product materials such as U metal, UO2, UO3, uranyl nitrate hexahydrate, uranium hexafluoride and U3O8 from the nuclear fuel cycle. This procedure is sufficiently accurate and precise to be used for nuclear materials accountability. This method can be used directly for the analysis of most uranium and uranium oxide nuclear reactor fuels, either irradiated or un-irradiated, and of uranium nitrate product solutions. Fission products equivalent to up to 10 % burn-up of heavy atoms do not interfere, and other elements which could cause interference are not normally present in sufficient quantity to affect the result significantly. The method recommends that an aliquot of sample is weighed and that a mass titration is used, in order to obtain improved precision and accuracy. This does not preclude the use of alternative techniques which could give equivalent performance. The use of automatic device(s) in the performance of some critical steps of the method has some advantages, mainly in the case of routine analysis.

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.

Vandens kokybė. Žarninių lazdelių (Escherichia coli) ir koliforminių bakterijų skaičiavimas. 2 dalis. Tikimiausiojo skaičiaus metodas (ISO/DIS 9308-2:2026)

This document specifies a method for the enumeration of E. coli and coliform bacteria in water. The method is based on the growth of target organisms in a liquid medium and calculation of the “Most Probable Number” (MPN) of organisms by reference to MPN tables or by use of appropriate formulae 1]. This method can be applied to a range of types of water (for example drinking water, groundwater, surface water, recreational water and wastewater),[2-5] including those containing a considerable amount of suspended matter and high background counts of heterotrophic bacteria. Users should satisfy themselves that any product used has been validated for its intended use (e.g. chlorinated drinking water) and should generate performance characteristics using ISO13843.[6] Performance characteristic data generated prior to 2017 using ISO TR 13843[7] is also acceptable. If a water sample has some background colour, the incubated sample should be compared to a blank control of the same water sample This method relies upon the detection of E. coli based upon expression of the enzyme β‑D‑glucuronidase and consequently does not detect some enteropathogenic strains of E. coli, which do not typically express this enzyme. Additionally, there are a small number of other E. coli strains that do not express β‑D‑glucuronidase. As they are β‑D‑galactosidase positive, they will appear as coliform bacteria.

Neorganinės trąšos. Tam tikrų parametrų nustatymas

This document specifies a reference to the method for the determination of the following specific parameters in inorganic fertilizers: — granulometry; — organic carbon content; — dry matter content. This document is applicable to the fertilizing products blends where a blend is a mix of at least two of the following components: fertilizers, liming materials, soil improvers, growing media, inhibitors, plant biostimulants, and where the following category: inorganic fertilizers is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If inorganic fertilizer is not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a fertilizing product blend is composed of components in equal quantity, the user decides which standard to apply. Variations in analytical methods for fertilizing product blends can lead to differing results as some components or matrix interactions can affect the outcome. Validation procedures have shown that developed standard methods are robust and reliable across diverse product compositions, but possible interferences and unexpected results when analysing fertilizing product blends are possible.

This document specifies product and system requirements related to cybersecurity threats in the following lifecycle steps: — product development (process and product requirements); — manufacturing; — installation; — operation and maintenance; — decommissioning. This document addresses the roles of product supplier and system integrator as shown in IEC 62443-4-1:2018, Figure 2, for the EUC. This document does not address the role of asset owner as shown in IEC 62443-4-1:2018, Figure 2, but defines requirements for the product supplier and system integrator of the EUC to establish documentation allowing the asset owner, referred to as the “EUC owner” in this document, to achieve and maintain the security of the EUC. This document specifies the minimum cybersecurity requirements for: — essential functions; — safety functions; — alarm functions. This document is applicable to EUCs that are capable of connectivity to external systems such as building networks, cloud services, or service tools. The capability to connectivity can exist through equipment permanently available on site, or equipment temporarily brought to the location during the installation, operation and maintenance, or decommissioning steps. EUC interfaces to external systems and services are in the scope of this document. External systems and services as such are out of the scope of this document.
