Railway applications - Simulation Credibility

This document sets out a framework to replace and/or complement physical tests with virtual tests by introducing simulation credibility for a given railway application. This covers simulation development, use, and management. Users of this document can be: - simulation engineers or organizations and their subcontractors, - standardization working groups to introduce simulations in their standards or - technical assessors and conformity assessment bodies. This document provides guidance, particularly when simulations are not yet defined. Where applicable, this document can be used in conjunction with existing standards pertaining to the use of simulations. If simulation is already recognized in existing domain-specific standards, this document does not modify the requirements of those standards. However, it may assist in future improvements and harmonization. It does not provide domain-specific guidance on applying simulations. For the use of technologies including, but not limited to, artificial intelligence, model-scale testing, and distributed computing, relevant potential technology based risks can arise.

Non-destructive testing - Ultrasonic testing of steel flat product of thickness equal or greater than 5 mm (reflection method)

This document describes a method for the ultrasonic testing of uncoated flat steel product for internal discontinuities. This document is applicable to flat product in nominal thickness range of 5 mm to 200 mm of non-alloyed or alloyed steel, excluding austenitic or austenoferritic steels. However, this document can be applied to the latter types of steels provided that the difference between the amplitude of the noise signal and that of the echo detection threshold is sufficient for the limit fixed. This document also defines five quality classes for the flat product body (classes S0, S1, SA, S2 and S3) and five classes (E0, E1, E2, E3, E4) for the edges (see Clause 13). Other methods of testing (e.g. by phased-array) or other test equipment may be used at the manufacturer's discretion provided that they give identical results to those obtained under the conditions of this document. In the event of a dispute, only the method defined in this document shall prevail. Testing of flat product of thickness less than 5 mm or higher than 200 mm may be the subject of special agreements between the parties concerned. The inspection is normally carried out in the place of production or on the premises of the supplier. If specified on the order, the inspection takes place in the presence of the purchaser or his representative1. A list of equivalent terms in several European languages is given in Annex A.

Residual current operated circuit-breakers without integral overcurrent protection for household and similar uses (RCCBs) - Part 1: General rules

This document gives general requirements and tests for residual current operated circuit-breakers without integral overcurrent protection for household and similar uses (hereafter referred to as RCCBs), for rated operational voltages not exceeding 440 V AC, with rated frequencies of 50 Hz, 60 Hz or 50/60 Hz and rated currents not exceeding 125 A, intended principally for protection against shock hazard. RCCBs are intended to provide fault protection (previously referred to as protection against indirect contact), the exposed conductive parts of the installation being connected to an appropriate earth electrode. They are also intended to be used to provide protection against fire hazards due to a persistent earth fault current. RCCBs having a rated residual operating current not exceeding 30 mA are used for fault protection and additional protection in the case of failure of the protective provisions against electric shock. This document applies to RCCBs performing simultaneously the functions of detection of the residual current, of comparison of the value of this current with the residual operating value and of opening of the protected circuit when the residual current exceeds this value. RCCBs are intended to be operated by ordinary or uninstructed persons and designed not to require maintenance. The requirements of this document apply for standard conditions (see 7.1). Additional requirements can be necessary for RCCBs used in locations which have severe environmental conditions. RCCBs within the scope of this document are intended for use in an environment with pollution degree 2 (see 7.3) and overvoltage category III. RCCBs are suitable for isolation. Special precautions (e.g. surge protective devices) can be necessary when excessive overvoltages are likely to occur on the supply side (for example in the case of supply through overhead lines, see IEC 60364-4-44 and IEC 60364-5-53). RCCBs are suitable for use in IT systems. RCCBs of the general type are resistant to current surges, including the case where surge voltages (as a result of switching transients or induced by lightning) cause loading currents in the installation without occurrence of flashover. RCCBs of type S are considered to be sufficiently resistant against unwanted tripping even if the surge voltage causes a flashover and a follow-on current occurs. Particular requirements are necessary for RCCBs intended to be used at frequencies other than 50 Hz or 60 Hz. For RCCBs incorporated in, or intended for association with socket-outlets only, the requirements of this document can be used, as far as applicable, in conjunction with the requirements of IEC 60884-1 or the national requirements of the country where the product is placed on the market. This document does not apply to: – RCCBs the current setting of which is adjustable without a tool; – RCCBs including batteries. This document is not intended to be used alone; it is intended to be used in conjunction with the relevant product standard, IEC 61008-2-1 or IEC 61008-2-2.

Soil quality - Inhibition of reproduction of the soil mite (Hypoaspis (Gaeolaelaps) aculeifer) by soil contaminants (ISO/DIS 21285:2025)

This document specifies a chronic test method for evaluating the habitat function of soils and determining effects of soil contaminants and substances on the reproduction of Hypoaspis aculeifer by ? mainly ? alimentary uptake. This method is applicable to soils and soil materials of unknown quality, e.g. from contaminated sites, amended soils, soils after remediation, industrial, agricultural or other sites under concern and waste materials (e.g. dredged material, municipal sludge from a wastewater treatment plant, composed material, or manure, especially those for possible land disposal). The reproduction (= number of juveniles) is the measured parameter of the test. The test reflects the bioavailability of a mixture of contaminants in natural soils (contaminated site soils) to a species which represents a trophic level which is not covered by other ISO standards. This test is not intended to replace the earthworm (see ISO 11268-2) or Collembola (see ISO 11267) reproduction tests since this species belongs not only to a different trophic group but also a different taxonomic group (= mites; i.e. arachnids) than those used usually. Effects of substances are assessed using a standard soil, preferably a defined artificial soil substrate. For contaminated soils, the effects are determined in the soil to be tested and in a control soil. Depending on the objective of the study, the control and dilution substrate (dilution series of contaminated soil) are either an uncontaminated soil comparable to the soil to be tested (reference soil) or a standard soil (e.g. artificial soil). This document provides information on how to use this method for testing samples (soils or substances) under temperate conditions. This document is not applicable to substances for which the air/soil partition coefficient is greater than one, or to substances with vapour pressure exceeding 300 Pa at 25 °C. NOTE The stability of the test substance cannot be ensured over the test period. No provision is made in the test method for monitoring the persistence of the substance under test.

Oil and gas industries including lower carbon energy - Materials for use in H2S-containing environments in oil and gas production - Part 2: Service environment assessment and material selection (ISO/DIS 15156-2:2025)

This document gives requirements and recommendations for the selection and qualification of carbon and low-alloy steels for service in equipment used in oil and natural gas production and natural gas treatment plants in H2S-containing environments, whose failure can pose a risk to the health and safety of the public and personnel or to the environment. It can be applied to help to avoid costly corrosion damage to the equipment itself. It supplements, but does not replace, the materials requirements of the appropriate design codes, standards or regulations. This document addresses the resistance of these steels to damage that can be caused by sulfide stress cracking (SSC) and the related phenomena of stress-oriented hydrogen-induced cracking (SOHIC) and soft-zone cracking (SZC). This document also addresses the resistance of these steels to hydrogen-induced cracking (HIC) and its possible development into stepwise cracking (SWC). This document is concerned only with cracking. Loss of material by general (mass loss) or localized corrosion is not addressed. Table 1 provides a non-exhaustive list of equipment to which this document is applicable, including exclusions. This document applies to the qualification and selection of materials for equipment designed and constructed using load controlled design methods. For design utilizing strain-based design methods, see ISO 15156-1:2020, Clause 5. Annex A lists SSC-resistant carbon and low alloy steels, and A.2.4 includes requirements for the use of cast irons. This document is not necessarily suitable for application to equipment used in refining or downstream processes and equipment.

Plastics pipes for the conveyance of fluids under pressure - Miner's rule - Calculation method for cumulative damage (ISO/DIS 13760:2026)

In general terms, Miner’s rule is a common approach to calculate how the accumulation of a specific load that varies over time effects the time until failure. This international standard specifies the application of Miner’s rule for calculating the design time until failure of plastics pipes and piping systems of plastics materials under varying, but known, load conditions. Miner’s rule can also be applied reciprocally to calculate the tolerable load levels along a desired design time. This international standard specifies particularly the application of Miner’s rule to calculate stress or pressure regimes, respectively, that are tolerable during a targeted design time for plastics or composite pipes. Further, the application of Miner’s rule on the effect of accumulated damage on polyolefins caused by oxidative attack under varying temperatures and times on the design life is specified. It is necessary to apply Miner's rule to each failure mechanism separately. Thus, for mechanical failure due to internal pressure, other failure mechanisms, such as oxidative or dehydrochlorinative degradative failure mechanisms, are to be neglected (assuming, of course, no interaction). A material may be used only when it is proven to conform to all failure mechanism criteria. NOTE Miner's rule is an empirically based procedure and is only a first approximation to reality.

Fine ceramics (advanced ceramics, advanced technical ceramics) — Test methods for fracture toughness of monolithic ceramics — Single-edge V-notch beam (SEVNB) method

ISO 23146:2012 specifies a method for the determination of the fracture toughness of advanced technical ceramics. The procedure makes use of single-edge V-notched bars, which are loaded in four-point bending until failure. It is applicable to monolithic ceramics with a grain size or major microstructural feature size larger than about 1 µm. The use of ISO 23146:2012 for yttria tetragonal zirconia polycrystal material (Y-TZP) is not recommended. The method might also be unsuitable for some other very tough or soft ceramics in which a sharp crack does not form at the root of the V-notch.

Railway applications - Testing and simulation for the acceptance of running characteristics of railway vehicles - Running safety under longitudinal compressive force

This document defines the assessment of endurable longitudinal compressive force (LCF) of a vehicle. The endurable longitudinal compressive force is a parameter depending on the vehicle design. It is used to estimate the risk of derailment of a vehicle as a result of being subjected to longitudinal compressive force, under operating conditions. NOTE 1 As operating conditions can vary in several aspects (infrastructure, train configurations etc.), this document defines uniform assessments of endurable longitudinal compressive force per vehicle in specific operating conditions. The main assessment of endurable longitudinal compressive force for conventional trains is derived from UIC 530-2:2011, which is based on practical tests performed in ERRI-B12. Assessments of endurable longitudinal compressive force for high-capacity trains in this document are required by the methodology of IRS 40421. IRS 40421 assesses operational train parameters. This document applies to the following types of vehicles: - single wagons; - permanently coupled units with standard ends between the vehicles; - permanently coupled units with diagonal buffers and screw couplers between the vehicles; - permanently coupled units with a bar coupler between the vehicles; - articulated units with 2-axle bogies; - wagons with 3-axle bogies; - low-floor wagons with eight or more axles (e.g. rolling road wagon); - vehicles with centre couplers; - railbound construction and maintenance machines as defined in EN 14033-1:2017. NOTE 2 This document defines the acceptance process to be followed by vehicles that are operated in a way that high longitudinal compressive force occur in the trains due to their operational environment (e.g. train composition, brake mode, track layout). The following vehicles are not in the scope of this document: - locomotives and passenger rolling stocks; - vehicles that are only operated in passenger trains. NOTE 3 Locomotives, passenger rolling stocks and vehicles operated in passenger trains only are not in the scope of this document as they either are subject to low longitudinal compressive force in operation or have sufficient endurable longitudinal compressive force due to their axle load. Acceptance criteria and test conditions as well as conditions for simulation are defined in this document. Conditions for dispensation of the assessment of the endurable longitudinal compressive force are also defined in this document. This document applies principally to vehicles which operate without restrictions on tracks with a gauge of 1 435 mm in Europe. NOTE 4 The influence on railway systems using other gauges is not sufficiently understood to extend the scope of this document to gauges other than 1 435 mm. NOTE 5 For wagons with centre couplers, a need for assessment of derailment risk due to Longitudinal Forces on other gauges (1 524 mm, 1 600 mm, 1 668 mm) has been expressed. The influence on railway systems using other gauges is not sufficiently understood. This document only introduces some notions to assess it independently from the gauge.
