Protezai. Apatinių galūnių protezų konstrukcijos bandymai. Reikalavimai ir bandymo metodai (ISO/DIS 10328:2025)

IMPORTANT - ISO 10328:2016 is suitable for the assessment of the conformity of lower limb prosthetic devices/structures with the strength requirements specified in 4.4 of ISO 22523:2006 (see NOTE 1). Prosthetic ankle-foot devices and foot units on the market, which have demonstrated their compliance with the strength requirements specified in 4.4 of ISO 22523:2006 through submission to the relevant tests of ISO 10328:2006, need not be retested to ISO 22675:2016. WARNING - ISO 10328:2016 is not suitable to serve as a guide for the selection of a specific lower limb prosthetic device/structure in the prescription of an individual lower limb prosthesis! Any disregard of this warning can result in a safety risk for amputees. ISO 10328:2016 specifies procedures for static and cyclic strength tests on lower-limb prostheses (see NOTE 2) which typically produce compound loadings by the application of a single test force. The compound loads in the test sample relate to the peak values of the components of loading which normally occur at different instants during the stance phase of walking.

Aerospace series - Programme management - Verification and validation of numerical models and simulations

This document provides an inventory of best practices, shared by actors from the aerospace and defence sector, concerning the verification and validation (V&V) of numerical simulations and models, in order to ensure the credibility of the outputs obtained in a logic of faster development of decision-making support, of reducing the number of physical tests, of shortening development times, of facilitating numerical qualification and certification, etc. These are all the major challenges concerning simulation. The approach applies to models based on physical equations. EXAMPLE Mechanics, acoustics, electrical, electromagnetism, thermal physics for electronics, fluid dynamics, multibody dynamics, multiphysics, optical, signal integrity and power integrity. The objective is to determine recommendations depending on the challenges of the simulation, in order to adapt the procedures to be applied to ensure the credibility of the simulation. The items being considered are: - criticality of the product and the simulation; - complexity of the phenomenon or the product; - capability, fidelity and maturity of the model; - product lifecycle; - skills; - verification and validation approach, with uncertainties quantification; - etc. This document is organized as follows: - terms and definitions; - general principles and concepts of simulation V&V: o the document’s objectives and added value; o state of the art; o different uses of simulation depending on the maturity (approximation level) of the model and product lifecycle, linked to the expected fidelity of the model and the simulation outputs; o presentation of the different types of models and impacts on criteria and quantities of interest, as well as on requirements; - recommended V&V process and activities (linked to the degree of maturity); - an example of a simulation plan template; - examples for a clearer understanding. The aim of this document is to complete and reference the information available in the literature. This document takes a generic approach so that it is applicable by most organizations and for different types and domains of simulation. This document addresses simulation specialists, simulation team managers and other stakeholders involved in the simulation process or decision-making support. This document provides recommendations for each criticality level, linked also to the level of confidence in the simulation, at each stage of the simulation process. Modelling and simulation have long been part of product qualification and certification, and the recommendations laid down in this document do not aim to replace the many qualification, certification and analysis processes already proven and established. The practices recommended in this document were specifically developed in response to potential future applications of modelling and simulation which could, in some cases, give it a more prominent role in qualification and certification, thereby reducing programme costs and development times.

Bandymo metodai bendrajam vėdinimui skirtų dujinius teršalus šalinančių oro valymo priemonių ir įtaisų veiksmingumui vertinti. 1 dalis. Dujinius teršalus šalinančios oro valymo priemonės (ISO/DIS 10121-1:2025)

ISO 10121-1:2014 aims to provide an objective laboratory test method, a suggested apparatus, normative test sections and normative tests for evaluation of three different solid gas-phase air cleaning media (GPACM) or GPACM configurations for use in gas-phase air cleaning devices intended for general filtration applications. ISO 10121-1:2014 is specifically intended for challenge testing and not for general material evaluation or pore system characterization. The three different types of GPACM identified in ISO 10121-1:2014 are GPACM-LF (particles of different shape and size intended for e.g. Loose Fill applications), GPACM-FL (FLat sheet fabric intended for e.g. flat one layer, pleated or bag type devices) and GPACM-TS (three dimensional structures that are many times thicker than flat sheet and e.g. used as finished elements in a device). The tests are conducted in an air stream and the GPACM configurations are challenged with test gases under steady-state conditions. Since elevated gas challenge concentrations (relative to general ventilation applications) are used, test data should be used to compare GPACM within the same configuration and not for the purpose of predicting performance in a real situation. It is also not implied that different GPACM configurations can be directly compared. The primary intention is to be able to compare like GPACM configurations to like, not between GPACM configurations. Testing of complete devices is described in ISO 10121‑2. To ensure objectivity for test equipment suppliers, no specific design of the test apparatus is defined: an example is illustrated in an annex. Instead normative demands for media sample holder design, apparatus properties and validation tests are specified.

This document defines the process, protective measures and demonstration of safety in accordance with EN 50126-1:2017 and EN 50126 2:2017 for AC and DC electric traction power supply systems for railways. This document can also be applied to urban rail and trolleybus systems. All these systems can be elevated, at-grade and underground. This document has two parts: — prEN 50562 1:2025 establishes the code of practice for conventional applications, functions and properties in electric traction power supply systems. — prEN 50562 2:2025 supports the implementation of non-conventional applications, functions and properties in electric traction power supply systems. This document applies to electric traction power supply systems, which are new or are undergoing major changes as defined in the legal framework. For similar technology and similar hazardous scenarios, the safety considerations can be used as a guideline. This document does not apply to: — underground mine traction systems, — cranes, transportable platforms and similar transportation equipment on rails, temporary structures (e.g. exhibition structures) in so far as these are not supplied directly or via transformers from the contact line system and are not endangered by the traction power supply system, — suspended cable cars, — funicular railways, — magnetic levitated systems, This document does not consider aspects like IT-security or protection against any other malevolent acts. It is assumed that those aspects are handled on the overall system level. NOTE For railways IT-security is covered in CLC/TS 50701. Because of the short life cycles of IT security applications it is advisable to separate IT-security functions from safety functions at least on virtual levels. E.g. the frequent patch processes for updating the IT-security applications is expected to be independent from safety applications.
