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.

Cybersecurity requirements for platforms of smartcards and similar devices including secure elements

The products with digital elements in the scope of this document are the platforms of smartcards and similar devices including secure elements, which consist of a tamper-resistant MCU/MPU and optionally an application environment or operating system. Platforms are designed to store and process sensitive data, and to protect it against physical and logical attacks by attackers with significant resources and skills, at AVA_VAN.4 (moderate attack potential) or AVA_VAN.5 (high attack potential) levels. Although platforms do not delegate data processing to remote entities, these can be involved in operations such as software update, configuration or key provisioning. The platform ensures the authentication of the remote entities before receiving/sending sensitive information and ensures this information is protected during the exchange. Platforms are intended for final products including, but not limited to, electronic identity cards, removable UICCs, eUICC, payment cards, physical access cards, digital tachograph cards or wrist bands with integrated payment secure elements, trust anchors in connected digital products and critical IT systems. This document defines technical requirements for platforms, which meet the essential requirements defined in Regulation (EU) 2024/2847 to the extent described in Annex ZZ. It also defines the methods for assessing the technical requirements. The expression of the technical requirements and the assessment methods use the Common Criteria (CC) formalism defined in the EN ISO/IEC 15408 series and EN ISO/IEC 18045:2023 supplemented by the EUCC state-of-the-art documents for the technical domain smart cards and similar devices. This document covers platforms conformant with the Protection Profiles (PPs) PP0084, PP0117, PP0104 and PP TPM, and identifies the gaps of these specifications against the CRA essential requirements. In this document, PP0104 also refers to the PP0104-based PP-Configuration 0107. The evaluation of platforms against PP0084, PP0117, PP0104 or PP TPM plus the applicable additional technical requirements which cover their gaps allow to demonstrate conformance with the CRA essential requirements. The technical requirements and the mappings against PP0084, PP0117, PP0104 and PP TPM are defined in Clause 7 and Annex B, respectively. This document also covers platforms consisting of a hardware layer and either an application environment, e.g. Java Card platform, or firmware/software. Annex C contains an informative mapping of Java Card platforms towards PP0099. Platforms can have discrete, integrated or embedded form factors, and employ technologies such as integrated circuits, programmable macros or system-in-package or system-on-chip. These do not affect the requirements or the assessment methods. Unless specified, clauses apply to all platforms, from pure hardware to platforms consisting of hardware, firmware and/or software. Platforms are accompanied by guidance which contains all the requirements and recommendations for the secure integration of the platform into further intermediate or final products and the secure usage of the platform by the external entities. The guidance covers all the non-platform aspects which can impact the security of the platform assets. The applications stored and/or running on the platforms, which are an integral part of the final products, are outside the scope of this document. prEN 18330:2026 applies to products composed of a platform and a set of applications.

Electronic fee collection - System architecture for vehicle-related tolling - Part 1: Reference model (ISO/DIS 17573-1:2025)

This document defines the architecture of electronic fee collection (EFC) system environments, in which a customer with one contract may use a vehicle in a variety of toll domains with a different toll charger for each domain. EFC systems conforming to this document can be used for various purposes including road (network) tolling, area tolling, collecting fees for the usage of bridges, tunnels, ferries, for access or for parking. From a technical point of view the considered toll systems may identify vehicles subject to tolling by means of electronic equipment on-board in a vehicle or by other means (e.g. automatic number plate recognition, ANPR). From a process point of view the architectural description focuses on toll determination, toll charging, and the associated enforcement measures. The actual collection of the toll, i.e. collecting payments, is outside of the scope of this document. The architecture in this document is defined with no more details than required for an overall overview, a common language, an identification of the need for and interactions among other standards, and the drafting of these standards. This document as a whole provides: — the enterprise view on the architecture, which is concerned with the purpose, scope and policies governing the activities of the specified system within the organization of which it is a part; — the terms and definitions for common use in an EFC environment; — a decomposition of the EFC systems environment into its main enterprise objects; — the roles and responsibilities of the main actors. This document does not impose that all roles perform all indicated responsibilities. It should also be clear that the responsibilities of a role may be shared between two or more actors. Mandating the performance of certain responsibilities is the task of standards derived from this architecture; — identification of the provided services by means of action diagrams that underline the needed standardised exchanges; — identification of the interoperability interfaces for EFC systems, in specialised standards (specified or to be specified).

Non-destructive testing - Radiographic inspection of corrosion and deposits in pipes by X- and gamma rays - Part 2: Double wall radiographic inspection (ISO/DIS 20769-2:2026)

This document specifies fundamental techniques of film and digital radiography with the object of enabling satisfactory and repeatable results to be obtained economically. The techniques are based on generally recognized practice and fundamental theory of the subject. This document applies to the radiographic examination of pipes in metallic materials for service induced flaws such as corrosion pitting, generalized corrosion and erosion. Besides its conventional meaning, "pipe" as used in this document is understood to cover other cylindrical bodies such as tubes, penstocks, boiler drums and pressure vessels. Weld inspection for typical welding process induced flaws is not covered, but weld inspection is included for corrosion/erosion type flaws. The pipes can be insulated or not, and can be assessed where loss of material due, for example, to corrosion or erosion is suspected either internally or externally. This document covers double wall inspection techniques for detection of wall loss, including double wall single image (DWSI) and double wall double image (DWDI). Note that the DWDI technique described in this document is often combined with the tangential technique covered in ISO 20769-1. This document applies to in-service double wall radiographic inspection using industrial radiographic film techniques, computed digital radiography (CR) and digital detector arrays (DDA).
