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.

Measurement of CO2 streams - Sampling and analysis for pipeline transportation

This document specifies requirements and recommendations for measuring the composition of CO2 streams during post capture pipeline transportation. The primary objective of this document is to establish standardized technical requirements and recommendations necessary for implementing regulations, commercial contracts, inventory ownership and fiscal transactions within the framework of Carbon Capture and Storage (CCS). This document includes measurements up to the storage injection points but does not cover Measurement, Monitoring, and Verification (MMV) once the CO2 has entered the geological storage complex. The differentiation between biogenic and non-biogenic CO2 in a CO2 stream is recognized as highly relevant for accounting purposes. However, the measurement methodologies for the biogenic CO2 fraction fall outside the scope of this document, which covers post-capture pipeline transportation. This document is not intended to differentiate between biogenic CO2 and CO2 produced from non-biogenic sources.

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.

Bitumens and bituminous binders - Determination of complex shear modulus and phase angle - Dynamic Shear Rheometer (DSR)

This document specifies a general method of using a dynamic shear rheometer (DSR) for measuring the rheological properties of bituminous binders. The procedure involves determining the complex shear modulus and phase angle of binders over a range of test frequencies and test temperatures when tested in oscillatory shear. From the test, the complex shear modulus, |G*|, and its phase angle, δ, at a given temperature and frequency are calculated, as well as the components G' and G" of the complex shear modulus. This method is applicable to un-aged, aged, stabilized and recovered bituminous binders. The test procedure in accordance with this document is not applicable for bituminous binders with particles larger than 250 μm (e.g. filler material, granulated rubber). WARNING - The use of this document can involve hazardous materials, operations and equipment. This document does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this document to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
