Geležinkelio taikmenys. Stacionarieji įrenginiai ir riedmenys. Elektrinės traukos maitinimo šaltinių ir riedmenų veikimo koordinavimo, užtikrinančio jų funkcinį suderinamumą, techniniai kriterijai. 1 dalis. Bendrieji dalykai

This document establishes requirements for the electrical aspects to achieve technical compatibility between rolling stock and electric traction systems, limited to: - co-ordination of protection principles between power supply and traction units, i.e. separation sections, train set current or power limitation, short circuit current discrimination, circuit breaker coordination and use of regenerative braking; - co-ordination of installed power on the line and the power demand of trains, i.e. traction unit power factor, train set current or power limitation, electric system performance, type and characterization; - compatibility assessment relating to harmonics and dynamic effects. Informative values are given for some parts of the existing European railway networks, in annexes. NOTE For those railways within the scope of EU Interoperability Directive, definitive values are set out in the register of infrastructure published in accordance with Article 49 of Directive (EU) 2016/797, and the list of items included in the register is described in the commission decision (EU) 2019/777. The following electric traction systems are within the scope of this document: - railways; - guided mass transport systems that are integrated with railways; - material transport systems that are integrated with railways. Information is given on electrification parameters to enable train operating companies to confirm, after consultation with the rolling stock manufacturers, that risks of non-compatibility are minimized and that there will be no consequential disturbance on the electrification system. The interaction between pantograph and overhead contact line is dealt with in EN 50367:2020. The interaction with the control-command and signalling subsystem is not dealt with in this document. Basic considerations have been included concerning the use of traction units with onboard electric traction energy storage in the electric traction power system. Details of this are dealt with in CLC/TS 50729:2025.

The amendment will address misunderstandings on provisions for AI/ML by providing additional guidance and clarifications without changing the fundamental technical requirements and recommendations of the standard. The amendment and its limitation to broadly editorial changes is based on following considerations: • Limited Standardization for AI: While AI/ML holds promise for various applications, current standardization efforts specific to AI/ML in safety-critical domains like railway are still in their early stages. This lack of mature and widely accepted standards for verifying and validating AI/ML systems in these contexts makes it challenging to reference or directly incorporate such technologies into the scope of EN 50716 (with less restrictive provisions) at this time. • Promoting Flexibility and Innovation: By clarifying the existing provisions and adding guidance without imposing new requirements, the amendment allows for flexibility and encourages developers to explore the potential of AI/ML (where is safe to do so). The following areas have already been identified by WG28 for the amendment: • Explicitly remind the scope of Table A.3: State that the table's techniques and measures are primarily intended for the design of the software architecture for safety-related functions (e.g. does not strictly apply to support tools). • Provide guidance on AI/ML usage: Explicitly acknowledge the potential of AI/ML in non-safety-critical areas and offer examples of possible applications (complementary to current recommendation for Basic Integrity, “-”, in Table A.3 for 13. Artificial Intelligence and Machine Learning). • Guidance on Support Tools: Ensure a consistent understanding of the AI/ML provisions related to support tools (& programming languages). This represent current view on potential changes - other areas may be identified during the amendment drafting, keeping into account the above mentioned limitations to broadly editorial changes.

This document specifies minimum requirements for the materials, design, construction, prototype testing and routine manufacturing inspections of fully wrapped composite gas cylinders for compressed, liquefied and dissolved gases. NOTE 1 For the purposes of this document, the word “cylinder” includes tubes (seamless transportable pressure receptacles of a water capacity exceeding 150 l and of not more than 3 000 l). This document is applicable to cylinders that comprise a liner of metallic material (welded or seamless) or non-metallic material (or a mixture thereof), reinforced by a wound composite consisting of fibres of glass, carbon or aramid (or a mixture thereof) embedded in a matrix. This document is also applicable to composite cylinders without liners. This document is not applicable to gas cylinders which are partially covered with fibres and commonly called “hoop wrapped” cylinders. For hoop wrapped composite cylinders, see EN 12257. NOTE 2 This document does not address the design, fitting and performance of removable protective sleeves. Where these are fitted, they are considered separately. This document is primarily for compressed, liquefied and dissolved gases other than LPG. NOTE 3 For dedicated LPG cylinders, see EN 14427.

Karštuoju būdu apdoroti nelegiruotojo ir smulkiagrūdžio plieno tuščiaviduriai statybiniai profiliuočiai. 1 dalis. Techninės tiekimo sąlygos

This document specifies technical delivery conditions for hot-finished seamless, electric welded and submerged arc welded steel structural hollow sections of circular, square, rectangular or elliptical forms. It applies to hollow sections formed hot, with or without subsequent heat treatment, or formed cold with subsequent heat treatment above 580 °C to obtain equivalent mechanical properties to those obtained in the hot formed product. NOTE 1 The requirements for tolerances, dimensions and sectional properties are specified in EN 10210-2. NOTE 2 The provisions that apply under the Construction Products Regulations (CPR) are specified in EN 10380. NOTE 3 The attention of users is drawn to the fact that whilst cold formed grades in EN 10219-1 can have equivalent mechanical properties to hot-finished grades in this document the sectional properties of square and rectangular hollow sections in EN 10210-2 and EN 10219-2 are not equivalent. NOTE 4 A range of material grades is specified in this standard and the user should select the grade most appropriate to the intended use and service conditions. The grades and mechanical properties of the finished hollow sections are generally comparable with those in EN 10025-2, EN 10025-3, EN 10025-4, EN 10025-5 and EN 10025-6. NOTE 5 The requirements for seamless and welded steel structural hollow sections for use in offshore structures are covered in EN 10225. NOTE 6 Spiral welded hollow sections must be used with caution in applications involving dynamic behaviour (fatigue stress) as, up to now, there is insufficient data regarding their performance.
