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.

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.

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.

NOTE Compliance criteria relating to data sheet parameters in this document are covered by IEC 63554 or IEC 62031 for safety, and IEC 63555 for performance. This third edition cancels and replaces the second edition published in 2023. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) addition of datasheets for GJ6.6d-2-x capped LED lamps.

Applies to electric storage heaters intended to heat the room in which they are located. It defines the main performance characteristics and describes methods for measuring these characteristics. It does not apply to heating appliances incorporated in the building structure, to central heating systems or to floor heating appliances.

This document applies to personal dosemeters with the following characteristics: a) They are worn on the trunk, close to the eye, or on the extremities. b) They measure the personal dose equivalents Hp(10), Hp(3), and Hp(0,07), from external X and gamma, neutron (not for Hp(3)), and beta radiations, and may measure the respective personal dose equivalent rates for the same radiations (for alarming purposes). c) They have a digital indication. This indication may or may not be attached. d) They have alarm functions for the personal dose equivalents or personal dose equivalent rates except for hybrid dosemeters. For hybrid dosemeters an alarm function for the personal dose equivalents shall be implemented in the associated readout system.

Applies to electric direct-acting room heaters. They may be portable, stationary, fixed or built-in. It defines the main performance characteristics and the methods for measuring these characteristics. For thermal-storage room heaters, see IEC 60531.

The EN 50483 series applies to overhead line fittings for tensioning, supporting and connecting aerial bundled cables (ABC) of rated voltage U0/U (Um): 0,6/1 (1,2) kV. This document defines the environmental tests in particular the climatic and corrosion ageing tests. The objective of these tests is to predict the behaviour of ABC accessories when subjected to sun radiation, to weather conditions (humidity, spraying water, heat, cold) and pollution. EN 50483-1, EN 50483-2, EN 50483-3 and EN 50483-4 specify which type tests included in this part of the standard are needed.

The EN 50483 series applies to overhead line fittings for tensioning, supporting and connecting aerial bundled cables (ABC) of rated voltage U0/U (Um): 0,6/1 (1,2) kV. This document applies to connectors used for the electrical connection of ABC. The connectors are designed to be installed where either the main and/or branch cable is ABC as defined by HD 626 S2. Tests described in this document are type tests.

IEC 61512-1:2026 applies to systems, specifications, and their use for implementing batch and related procedure-oriented manufacturing controls in the process industries. This document establishes a reference model framework for procedure-oriented control, defines terms to help explain the model relationships and usage, and describes general criteria for evaluating conformance. This follows the principle of separation between recipe procedural elements and equipment procedural elements enabling operations to define recipes without the need of changes in equipment procedures. This second edition cancels and replaces the first edition published in 1997. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Models and text are modified to provide more detail and clarity. Key clarifications are: 1) Two types of equipment modules are defined: generic and recipe-aware. All recipe-aware equipment modules contain procedural control and can be used as phases in the recipe. 2) Execution of all procedural control contained directly in units is part of the Unit Supervision activity. 3) The relationships between types of recipes, recipe components, and equipment control are more fully described and illustrated. 4) Entity relationship diagrams have been replaced with more intuitive UML instance diagrams, except for the equipment entity model. 5) The transition diagram for the procedural states example has been updated with a more intuitive and complete UML state diagram. 6) References to other standards in the series and to IEC 62264 are included to provide direction for further clarification of selected topics. 7) Activity names are capitalised to help prevent confusion with similar terms, such as their underlying functions. b) Previous Clauses 4 through 6 (now Clauses 4 through 8) were rearranged to provide a clearer top-down organisation of the document. Key changes are: 1) Removing the lower levels of the physical (role-based equipment) model (see 4.4.2) to eliminate redundancy because their groupings are defined by the associated functionality in the equipment entity model and are not meaningful for batch control without those associations. 2) Describing equipment control and the equipment entity model immediately after the physical (role-based equipment) model and describing each level as completely as possible without excessive use of forward references (see 4.4.3). 3) Combining the descriptions of basic, procedural, and coordination control with their usage in each type of equipment entity, providing a single consolidated discussion of each type of control (see Clause 5) 4) Additional considerations to support application of the models have been grouped in Clause 7 to clarify their supporting relationship to the core models. c) Clause 9 was added to define completeness, compliance, and conformance in relation to this document. d) Annex B was added to provide a more expansive procedural state reference model. The model found in Clause 7 can be considered a collapsed version of this more general model. e) Annex C was added to clarify a number of points concerning the models, their application, and the new Clause 9 on conformance and compliance. f) Annex E was added to more fully describe the changes in this update to IEC 61512-1:1997.
