Fixed installations and rolling stock for railway applications - Technical criteria for the coordination between electric traction power supply systems and rolling stock to achieve interoperability - Part 1: General

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.

Food authenticity - Determination of 18O/16O isotope ratios in liquid aqueous food matrices by Equilibration - Isotope Ratio Mass Spectrometry (Eq-IRMS)

This document specifies a method for instrumental analysis by equilibration-isotope ratio mass spectrometry (Eq-IRMS) of liquid, aqueous food matrices to determine ¹⁸O/16O isotope ratios of the water of the product. The ¹⁸O/¹⁶O isotope ratios obtained by following this document are expressed as δ¹⁸O values relative to internationally recognised reference materials. This document does not apply to sample preparation. It is assumed that the food sample has been pre-treated as necessary and homogenised. Similarly, the interpretation of the obtained δ¹⁸O values is not covered by this document. Following this protocol will result only in isotope delta values for the sample materials. Although other instrumental techniques can be applied to determine δ¹⁸O values in liquid, aqueous food materials, these other techniques are not covered by this document.

Railway Applications - Requirements for software development

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.

Water quality - Enumeration of Escherichia coli and coliform bacteria - Part 2: Most probable number method (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.
