Vandens kokybė. Bendrojo sujungtojo azoto kiekio (ST-TNb) vandenyje nustatymas mažo masto tyrimo naudojant užsandarintus mėgintuvėlius metodu. 1 dalis. Dimetilfenolio spalvinė reakcija (ISO 23697-1:2023)

This document specifies a method for the determination of total bound nitrogen (ST-TNb) in water of various origins: groundwater, surface water, and wastewater, in a measuring range of concentration generally between 0,5 mg/l and 220 mg/l of ST-TNb using the small-scale sealed tube method. Different measuring ranges of small-scale sealed tube methods can be required. The measuring ranges can vary depending on the type of small-scale sealed tube method of different manufacturers. It is up to the user to choose the small-scale sealed tube with the appropriate application range or to adapt samples with concentrations exceeding the measuring range of a test by preliminary dilution. NOTE The results of a small-scale sealed tube are most precise in the middle of the application range of the test. All small-scale sealed tube methods are based on a heated alkaline potassium persulfate oxidation in a heating block. Different digestion temperatures, 100 °C or 120 °C or 170 °C, and different digestion times are applicable. Dimethylphenol colour reactions are applied, depending on the typical operating procedure of the small-scale sealed tube used, see Clause 9.

This document specifies procedures for the evaluation of basic performance parameters of the radiographic film digitisation process such as spatial resolution and spatial linearity, density range, density contrast sensitivity and characteristic transfer curve. They can be integrated into the system software and together with a standard reference film (see Annex B) used for quality control of the digitisation process. This reference film provides a series of test targets for performance evaluation. The test targets are suitable for evaluating a digitisation system with a basic spatial resolution down to 10 µm, a density contrast sensitivity down to 0,02 optical density, a density range of 0,5 to 4,5 and a film size capacity of (350∙430) mm2.

Plastikai. Standartinių gaisrinių bandymų naudojimo rekomendacijos (ISO/DIS 10840:2025)

ISO 10840:2008 covers the following aspects of fire testing of plastics materials and products: selection of appropriate tests that reflect realistic end-use conditions; grouping of the reaction-to-fire characteristics that any given test or tests can measure; assessment of tests as to their relevance in areas such as material characterization, quality control, pre‑selection, end-product testing, environmental profiling and DfE (Design for the Environment); definition of potential problems that may arise when plastics are tested in standard fire tests. The scope of the standard does not include the development or design of new fire tests for plastics. However, the flexibility of approach that is indicated with respect to the mounting and fixing of test specimens will be valuable when fire-testing laboratories and certification bodies are considering how to evaluate ranges of plastics that are used in different ways.

Sveikatos informatika. Sąvokų sistema sveikatos priežiūros tęstinumui palaikyti (ISO 13940:2025)

ISO 13940:2015 defines a system of concepts for different aspects of the provision of healthcare. The core business in healthcare is the interaction between subjects of care and healthcare professionals. Such interactions occur in healthcare/clinical processes and are the justification for the process approach of ISO 13940:2015. To be able to represent both clinical content and clinical context, ISO 13940:2015 is related to a generic healthcare/clinical process model as well as comprehensive concept definitions and concept models for the clinical, management and resource aspects of healthcare services. In practice ISO 13940:2015 covers the concept definitions needed whenever structured information in healthcare is specified as a requirement. The definitions are intended to refer to the conceptual level only and not to details of implementation. ISO 13940:2015 will cover all levels of specifications in the development of logical reference models within the information viewpoint as a common basis for semantic interoperability on international, national or local levels, information systems, and information for specified types of clinical processes.

The machines are designed to process solid wood and material with similar physical characteristics to wood, with hand feed or integrated feed. This document is intended to be used in conjunction with the other parts of the ISO 19085 series, applicable to specific machine types. The extent to which all significant hazards of a specific machine type are covered is indicated in the specific part of the ISO 19085 series relevant to that machine type. The hazards covered, at least partly, by the requirements of this document, are listed in Annex A. It is not applicable to machines intended for use in potential explosive atmospheres or to machines manufactured prior to the date of its publication.
