IEC 61496-3:2025 specifies additional requirements for the design, construction and testing of non‑contact electro-sensitive protective equipment (ESPE) designed specifically to detect persons or parts of persons as part of a safety-related system, employing active opto-electronic protective devices responsive to diffuse reflection (AOPDDRs) for the sensing function. Special attention is directed to requirements which ensure that an appropriate safety-related performance is achieved. An ESPE can include optional safety-related functions, the requirements for which are given both in Annex A of this document and in Annex A of IEC 61496‑1:2020. NOTE "Non-contact" means that physical contact is not required for sensing. This document does not specify the dimensions or configurations of the detection zone and its disposition in relation to hazardous parts for any particular application, nor what constitutes a hazardous state of any machine. It is restricted to the functioning of the ESPE and how it interfaces with the machine. AOPDDRs are devices that have either - one or more detection zone(s) specified in two dimensions (AOPDDR-2D), or - one or more detection zone(s) specified in three dimensions (AOPDDR-3D) wherein radiation in the near infrared range is emitted by an emitting element(s). When the emitted radiation impinges on an object (for example, a person or part of a person), a portion of the emitted radiation is reflected to a receiving element(s) by diffuse reflection. This reflection is used to determine the position of the object. Opto-electronic devices that perform only a single one-dimensional spot-like distance measure­ment, for example, optical proximity switches, are not covered by this document. This document is limited to ESPE that do not require human intervention for detection. It is limited to ESPE that detect objects entering into or being present in a detection zone(s). This document does not address those aspects required for complex classification or differentiation of the object detected. This document does not address requirements and tests for outdoor application. Excluded from this document are AOPDDRs employing radiation with the peak of wavelength outside the range 820 nm to 1 100 nm, and those employing radiation other than that generated by the AOPDDR itself. For sensing devices that employ radiation of wavelengths outside this range, this document can be used as a guide. This document is relevant for AOPDDRs having a minimum detectable object size in the range from 30 mm to 200 mm. This document can be relevant to applications other than those for the protection of persons, for example, for the protection of machinery or products from mechanical damage. In those applications, different requirements can be appropriate, for example when the materials that are recognized by the sensing function have different properties from those of persons and their clothing. This document does not deal with electromagnetic compatibility (EMC) emission requirements. This fourth edition cancels and replaces the third edition published in 2018. This edition constitutes a technical revision.

IEC 63402-1:2025 specifies general requirements and the architecture between the Point of Common Coupling (PCC) and smart devices (SD) operating within the Smart Grid premises-side system (i.e. residential or commercial but not industrial premises). This document does not include requirements for: - safety - electromagnetic compatibility (EMC); - data security, as it is assumed that the underlying protocols will take the data security aspect into account - special equipment (e.g. legacy heat pumps) with a direct physical connection to the grid, as such equipment bypasses the customer energy manager (CEM) and is not HBES/BACS enabled (covered by other standards than the IEC 63402 series). This group EE publication is primarily intended to be used as an EE standard for the products mentioned in the scope, but is also intended to be used by TCs in the preparation of publications for products which are included in the boundary mentioned in the scope of this document. It has the status of a group energy efficiency publication in accordance with IEC Guide 118.

IEC 60794-1-133: 2025 defines the test procedure to demonstrate the ability of an optical fibre cable to withstand multiple coiling and uncoiling on a specified diameter of cable reel. This test is primarily intended to evaluate the performance of cables for mobile rapid or multiple deployment. See IEC 60794‑1‑2 for a reference guide to test methods of all types and for general requirements. This first edition of IEC 60794-1-133 cancels and replaces Method E33 of the second edition of the IEC 60794-1-21:2015/AMD1:2020, which will be withdrawn. It includes an editorial revision, based on the new structure and numbering system for optical fibre test methods.

IEC 63522-45:2025 used for testing electromechanical elementary relays (electromechanical relays, reed relays, reed contacts, reed switches and technology combination of these) and evaluates their ability to perform under expected conditions of transportation, storage and all aspects of operational use.

IEC 60931-1:2025 is applicable to both non-self-healing capacitor units and non-self-healing capacitor banks intended to be used, particularly, for power-factor correction of AC power systems having a rated voltage up to and including 1 000 V and frequencies 15 Hz to 60 Hz. This document also applies to capacitors intended for use in power filter circuits.

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.

IEC 60122-2:2025 has been compiled in response to a generally expressed desire on the part of both users and manufacturers for guidelines to the use of quartz crystal units for filters and oscillators so that the crystal units may be used to their best advantage. It draws attention to some of the more fundamental questions which will be considered by the user before it places its order for a unit for a new application, and in so doing will, it is hoped, help ensure against unsatisfactory performance, unfavourable cost and non-availability. It is not the function of this document to explain theory, nor to attempt to cover all the eventualities that can arise in practical circumstances. Lastly, it it is not considered as a substitute for close liaison between manufacturer and user. Standard specifications, such as those of the IEC of which these guidelines form a part, and national specifications or detail specifications issued by manufacturers, will define the available combinations of the resonant characteristics and the temperature characteristic. These specifications are compiled to include a wide range of quartz crystal units with standardized performances. It cannot be over-emphasized that it is the responsibility of the user , wherever possible, to select the quartz crystal units from these specifications, when available, even if it can lead to making small modifications to the circuit to enable the use of standard resonators. This applies particularly to the selection of the nominal frequency. This edition includes the following significant technical changes with respect to the previous edition: a) addition of SC cut type and related requirements; b) addition of ageing calculation and low level of drive requirements according to the general specification, c) update of the frequency temperature curve according to the common cut requirements; d) removal of infrequently used product types.

IEC 63267-3-81: 2025 defines the dimensional limits of an optical interface for reference connectors with rectangular ferrules necessary to meet specific requirements for fibre-to-fibre interconnection of non-angled polished multimode reference connectors with rectangular ferrules intended to be used for attenuation measurements as defined in IEC 63267‑2‑2. Ferrule dimensions and features are contained in the IEC 61754 series of fibre optic interface standards.One grade of reference connector is defined in this document. The reference connector is terminated to restricted IEC 60793-2-10 A1-OM2b to A1-OM5b fibre at 850 nm band only. The geometrical dimensions and tolerances of the specified reference connector have been developed primarily to limit the variation in measured attenuation between multiple sets of two reference connectors, and therefore to limit the variation in measured attenuation between randomly chosen reference connectors when mated with connectors in the field or factory.

IEC 63267-3-61: 2025 defines the dimensional limits of an optical interface for reference connectors with 2,5 mm or 1,25 mm diameter cylindrical zirconia (ZrO2) ferrules necessary to meet specific requirements for fibre-to-fibre interconnection of non-angled polished multimode reference connections as defined in IEC 63267-2-2. Ferrule dimensions and features are contained in the IEC 61754 series of fibre optic connector interface standards. One grade of reference connector, Rm1, is defined in this document. The reference connector is terminated to restricted IEC 60793-2-10 using A1-OM2b to A1‑OM5b fibre in 850 nm band only. The geometrical dimensions and tolerances of the specified reference connector have been developed primarily to limit the variation in measured attenuation between multiple sets of reference connectors, and therefore to reduce the variation in measured attenuation between an arbitrarily chosen reference connector when mated with a connector in the field or factory. This first edition and the first edition of IEC 63267-2-2 cancel and replace the first edition of IEC 61755-6-2 published in 2018. This edition constitutes a technical revision. The document includes the following significant technical changes with respect to the previous edition: a) Definition of a reference grade, Rm1 interface; b) Inclusion of A1-OM2b to A1-OM5b fibres; c) Updates to normative references; d) The addition of Annex A, which describes the attenuation test limits of reference grade Rm1 connectors to grade Bm connectors; e) A new Annex B that describes the allowable fibre undercut.

IEC 62508: 2025 provides guidance on current knowledge and practice concerning dependability in an operational environment, in terms of the humans, teams and organizations involved in conducting the work. It is part of a suite of IEC standards that are intended to address the dependability of both the technical and human elements of equipment and organizations. This document describes the human elements of a typical operational system, and the importance of those elements to overall dependability. It also describes the means of assessing how well these elements are functioning, and general concepts on how the reliability of humans can be improved. These elements typically include the individual workers, the groups or teams into which they are organized, the interfaces between humans and technical systems, and the overall organization. The following guidance is applicable to any industry that depends on human-systems interactions involving the technology, software, or systems of work required to support the production and safety objectives of an organization. This document primarily addresses complex technical systems, but some parts are also applicable to the manufacturing of industrial and consumer products. Principles for design of the human-machine interface (usability) are described, and further information can be found in the technical literature and in relevant product standards. Although this document does not specifically cover worker health or safety, the application of this document can raise related issues, particularly in process safety, which is closely associated with system reliability. This second edition cancels and replaces the first edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) The emphasis on user-centred design in the previous edition was reduced in favour of a greater emphasis on human dependability in an existing operational environment. b) The emphasis on human error and error-rate determination methods was reduced in favour of a greater emphasis on means of providing organizational support for the workforce in their execution of required tasks. c) Where appropriate, discussions of human factors in an operational environment were aligned with current theory, terminology and practice.
