Method for the determination of the proof and the comparative tracking indices of solid insulating materials

SIST EN IEC 60112:2025

IEC 60112:2025 specifies the method of test for the determination of the proof and comparative tracking indices of solid insulating materials on pieces taken from parts of equipment and on plaques of material using alternating voltage. This document provides a procedure for the determination of erosion when required. The proof tracking index is used as an acceptance criterion as well as a means for the quality control of materials and fabricated parts. The comparative tracking index is mainly used for the basic characterization and comparison of the properties of materials. This test method evaluates the composition of the material as well as the surface of the material being evaluated. Both the composition and surface condition directly influence the results of the evaluation and are considered when using the results in material selection process. The described test method is designed for a test voltage up to 600 V AC, because higher test voltages and DC voltage will lead to a reduced test severity. Test results are not directly suitable for the evaluation of safe creepage distances when designing electrical apparatus. The results of this method have been used for insulation coordination of equipment. It is important that use of these results also considers the overvoltage levels, creepage distances, and establishes the pollution degree to which the product insulation system will be expected to be subjected. This is in compliance with IEC 60664-1. This basic safety publication focusing on a safety test method is primarily intended for use by technical committees in the preparation of safety publications in accordance with the principles laid down in IEC Guide 104 and lSO/lEC Guide 51. One of the responsibilities of a technical committee is, wherever applicable, to make use of basic safety publications in the preparation of its publications. This sixth edition cancels and replaces the fifth edition published in 2020. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - In 7.3, the term "resistivity" has been replaced by "conductivity". It has the status of a basic safety publication in accordance with IEC Guide 104.

Audio/video, information and communication technology equipment – Safety – Power transfer between communication equipment ports using communication wires and cables cabling at non-mains voltage above 60 V DC and ES2/ES3 AC voltage

kSIST FprEN IEC 63316:2026

IEC 63316:2026 prescribes safeguards, test methods and compliance requirements intended to reduce the risk of electrical shock and fire associated with voltage and current at voltages greater than 60 V DC and 60 V AC. This document applies to equipment ports intended to supply and receive operating power from communications equipment ports using communication wires and cables. It covers particular requirements for circuits that are designed to transfer AC or DC power from a power sourcing equipment (PSE) (3.1.2) to a powered device (PD) (3.1.3), including repeaters, amplifiers, Optical Network Units, Remote DSLAMs, service provider terminating equipment, remote telecommunications cabinets and equipment, and midspan passive equipment connected to the PSE (3.1.2) and PD (3.1.3). The power transfer of equipment ports covered by this document uses non-mains AC voltage or non-mains DC voltage above 60 V DC classified as ES2 according to 5.2.1.2 of IEC 62368-1:2023 or, in some very controlled cases, classified as ES3 according to IEC 62368-1:2023. EXAMPLES - DC power transfer using voltages above 60 V DC but ≤ 120 V DC, classified as ES2; - Some telecommunications networks where the voltage was formerly called TNV-3 (see IEC 62368-1:2023, Table W.3), typically used for line, span or express powering outside North America, Long Range Reverse Power Feeding, HDSLx line powering ISDN, Line Powering Primary Rate E1; - Some North American telecommunications networks between the utility service providers´ PSE (3.1.2) and service providers side of the PD (3.1.3) at the PNI (3.1.8); - For DC power transfer using voltages ≥ 120 V DC at ES3: RFT circuits and the associated telecommunications network equipment and cabling used by communications service providers and communications utilities (for example, line powered E1/T1, HDSLx, SHDSLx, xDSL, repeaters, and telecommunications line powering up or line powering down converters as applicable), Optical Network Units, remote DSLAMs, etc. These RFT circuits are used between the utility service providers PSE (3.1.2) and service providers side of the PD (3.1.3) at the PNI (3.1.8). The customer facing ports of this equipment are at voltage not exceeding 60 V DC and are covered by IEC 62368-1:2023, see Annex A for deployment topologies; - For AC/DC remote powering voltage above ES1 over coaxial cable in circuits used by cable television utility service providers for repeaters, amplifiers, Optical Network Units. The customer facing ports of this equipment are at voltage not exceeding 60 V DC that are covered by IEC 62368-1:2023. NOTE 1 Any communications cable that permits power transfer between communication equipment is considered a communication cable even if communication does not take place. For example, a line powering up or line powering down converters as applicable used to power remote telecommunications equipment, can provide limited communications RFT power and not necessarily any superimposed data or signalling. This document does not cover equipment interfaces within the scope of IEC 63315. NOTE 2 IEC 63315 covers equipment intended to either supply or receive charging, or operating power from ICT interfaces using ICT wires and cables such as PoE, USB, HDMI, etc, or any of these combined. This document does not cover ringing signals that are in the scope of IEC 62368-1 or in the scope of IEC 62949:2017. This document does not cover traditional telecommunications technologies which operate at voltages not exceeding 60 V DC (circuits classified as ES1 according to 5.2.1.1 of IEC 62368-1:2023 and Tabl

Superconductivity - Part 15: Electronic characteristic measurements - Intrinsic surface impedance of superconductor films at microwave frequencies

SIST EN IEC 61788-15:2026

IEC 61788-15:2026 describes measurements of the intrinsic surface impedance (Zs) of HTS films at microwave frequencies by a modified two-resonance mode dielectric resonator method. The object of measurement is to obtain the temperature dependence of the intrinsic Zs at the resonant frequency f0. The frequency and thickness range and the measurement resolution for the Zs of HTS films are as follows: - frequency: up to 40 GHz; - film thickness: greater than 50 nm; - measurement resolution: 0,01 mΩ at 10 GHz. It is crucial that the Zs data at the measured frequency, and that scaled to 10 GHz be reported for comparison, assuming the f2 rule for the intrinsic surface resistance, Rs (f < 40 GHz), and the f rule for the intrinsic surface reactance, Xs. This second edition cancels and replaces the first edition published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - informative Annex B, combined relative standard uncertainty in the intrinsic surface impedance is added; - the terms, ‘precision and accuracy’, are replaced with uncertainty; - results from a round robin test are added.

EN IEC 60413:2026(Main)

Test procedures for determining physical properties of brush materials

SIST EN IEC 60413:2026

IEC 60413:2026 concerns graphite-based grades that are used for sliding electrical contacts, such as carbon brushes or pantograph strips. By extension, it is possible to apply the test procedures of this document to all electrical sliding contacts for electrical transmission appliances and to other appliances of graphite-based materials (heat exchangers, bearings, etc.). This document specifies uniformized procedures for determining their following properties: - density and porosity; - resistivity; - flexural strength; - hardness; - ash content. In addition, it provides recommendations on test procedures for other properties: - Mechanical properties: Charpy impact test, compressive strength, tensile strength (Annex B). - Thermal properties: coefficient of thermal expansion, specific heat capacity, thermal conductivity (Annex C). The properties determined by these tests are inherent to the graphite-based materials and it is therefore important to distinguish them from performance characteristics in operation on electrical equipment (carbon brush in an electrical rotating machine, contact strips on a pantograph, etc.). Since these materials are generally brittle, porous materials, it is reasonable that their properties vary much more than the same properties in metals. Some test methods are suitable for use in production quality control (routine tests), others only for more thorough investigations, using precise laboratory techniques (see Annex A). WARNING — The use of this document can involve hazardous substances, operations and equipment. It does not purport to address all of the safety or environmental problems associated with its use. It is the responsibility of the user of this document to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. This second edition cancels and replaces the first edition published in 1972. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Title modified. b) Addition of definitions in Clause 3. c) Clause 5 on test specimen: Nomenclature and addition of the different types of test specimen, specification on their dimensions, tolerances and preparation. d) Improvement of test procedures of the properties already disclosed in the previous edition (Clause 6 to Clause 11). e) Separation of apparent density and apparent porosity (respectively Clause 6 and Clause 10). f) Resistivity (Clause 7): Addition of the eddy current method. g) Rebound hardness (Clause 9): Addition of a new model of scleroscope and addition of Leeb method, as a possible alternative to the traditional scleroscope method. h) Common elements of the test report in a dedicated Clause 12. i) Addition of Annex A (normative): introduction of tests categories (serial/type tests), list of properties to be tested for each test category of test according to their purpose. j) Addition of Annex B: test procedures for other mechanical properties than flexural strength and hardness: tensile, compressive and impact strength. k) Addition of Annex C: test procedures for thermal properties (coefficient of linear expansion, specific heat capacity and thermal conductivity). l) Addition of Annex D: supplement to density and porosity. m) Addition of Annex E: recommendations on methods for elements analysis. n) Addition of Annex F: supplem
