Water quality - Uranium - Test method using alpha liquid scintillation counting (ISO/DIS 13169:2025)

This document specifies the measurement method for the determination of total activity concentration of uranium isotopes in non-saline waters by extraction and liquid scintillation counting. This method covers the measurement of soluble uranium isotopes in water in activity concentrations between approximately 2·10−3 Bq/kg and 10 Bq/kg when analysing a 1 l test sample volume with a 60 000 s counting time with a typical alpha LSC instrument. The ratio 234U/238U can also be determined. This method has not been tested for the measurement of other uranium isotopes.

Railway applications - Hydrogen and fuel cell systems for rolling stock - Part 2: Hydrogen fuel system

This document amends EN IEC 63341-2 which applies to onboard hydrogen fuel systems used to supply the fuel cells for the traction power and the auxiliaries supply of rolling stock vehicles (such as hybrid vehicles as defined in EN IEC 62864-1). NOTE 1 This document may also be used as informative recommendations for applications with hydrogen internal combustion engines. EN IEC 63341-2 applies to hydrogen storage in gaseous form. Other means of storage (such as liquid, liquid cryo-compressed, metal hydrides) are not covered in this document. EN IEC 63341-2 applies to any rolling stock type (e.g. light rail vehicles, tramways, streetcars, metros, commuter trains, regional trains, high speed trains, locomotives). EN IEC 63341-2 addresses the mechanical, fluidic and electrical interfaces between the on-board hydrogen fuel system and fuelling station. The fuelling station, fuelling protocol and communication for the fuelling protocol are not in the scope of this document. EN IEC 63341-2 defines: – the scope of supply of hydrogen fuel system (HFS) and the description of the interfaces with sub-systems internal and external to the rolling stock such as fuel cell power system, fuelling station systems; – the environmental constraints; – the design requirements to support HFS compliance with railway applications; – the safety and reliability requirements to design and install the HFS for railway applications; – the marking and labelling requirements; – the requirements related to storage, transportation, installation and maintenance; – the validation (type, routine and investigation tests) requirements

This document is intended to allow for different implementations based on a company’s specific business environment. This document is not intended to incorporate company specific requirements and does not dictate specific organizational structures within a company. This document does not specify a design or an implementation of an archive system. Actual implementations can distribute responsibilities or break out functionality differently. This document assumes that all requirements for configuration management of the product data are in place and therefore are not specifically described in this document.

Piping systems for rehabilitation of underground drains, sewers and water supply networks - Part 4: Thermoplastic composite materials (ISO/DIS 11300‑4:2025)

This document specifies requirements and test methods for pipes and fittings which are part of piping systems for the renovation of underground non-pressure drainage and sewerage networks. It is applicable to pipes, fittings and assemblies, made from thermoplastic composite materials, as manufactured and as installed. It is not applicable to the existing pipeline. It is applicable to technique families for renovation: — lining with spirally-wound (SWO) pipes; — lining with a rigidly anchored plastic inner layer (RAPL). and intended to be used at an operating temperature of 20 °C as the reference temperature. In the case of lining with SWO pipes, where the pipes, are formed on site, to a fixed or variable diameter, by spirally winding and jointing a pre-manufactured profiled plastics strip, this document applies to, strips made of unplasticized poly(vinyl chloride) (PVC U), or of polyethylene (PE), with or without steel stiffening elements, and installed with or without integral locking mechanism. In the case of lining with RAPL, where a single rigid annulus of structural cementitious grout is formed behind a plastics inner layer serving as permanent formwork anchored to the grout. This document applies to integrally joined profiled plastics strips of PVC-U or PE or studded sheets of PE, and grout systems with or without steel reinforcement. It does not apply to the structural design of the lining system. NOTE Systems with multiple annuli are available, but these are controlled by patent rights and not covered by this document.

Aerospace series - LOTAR - Long Term Archiving and Retrieval of digital technical product documentation such as requirements, architecture, simulation, and analytical data - Part 500: Fundamentals and Concepts for Long Term Archiving to enable Model-based Systems Engineering

1.1 In Scope The EN 9300-5xx series specifies the methods for long term archiving and retrieval of MBSE data represented as digital models. The characterization of models that are considered in scope of this document and the MBSE process use cases include: - product or system design requirements models; - functional architecture models; - logical architecture models (system structure, arrangement, connectivity, software allocations and controls, and part relationships); - numerically-based system analysis and simulation models, generally regulated 1D control loop models featuring system components and transport elements (tubing, piping, signalling, software); - verification and validation of requirements; - protocol dependent signal or communication networks; - multi-model linking and system parametric models; - system trade study models; - the solution architecture models and data that are needed to implement the system and generate system engineering data for downstream designs. 1.2 Out of Scope The EN 9300-5xx series does not address the original product model design process, or a specific configuration management process for the LOTAR archive. It does not address models depicting part specific technical data (physical materials or detail part standards). It is assumed that these archiving processes are within the scope of other parts of the EN 9300 series such as the 1xx series for CAD, the 2xx series for Product Data Management (PDM) data, or by applying existing alternative industry standards, or existing company business procedures. Typical models and capabilities considered out of scope of this document include: - physical spatial models or composite structures (as described by other LOTAR Parts); - Finite Element and CFD models (as described by other LOTAR Parts); - Product Data Management models (as described by other LOTAR Parts); - electrical circuit boards, or physical wiring parts or systems (described by other LOTAR Parts or standards); - the software development process and software models that are outside of the context of software parts, behaviours, or functions that represent software code within a model; - how to preserve property and access rights, or government acquisition-regulatory controls; - new standards, or major revisions to existing MBSE standards that were not available or applicable prior to the publication of this document.
