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.

From this edition, the CLC TS 50654-2 is the adoption (identical) of the IEC TS 63291-2 (not covered by a parallel procedure). This document defines aspects on planning, specification, and execution of multi-vendor HVDC grid systems also referred to as HVDC grids. The terms "HVDC grid systems" or "HVDC grids" are used in this document to describe HVDC systems for power transmission having more than two HVDC stations connected to a common DC circuit. The DC circuit can be of radial or meshed topology or a combination thereof. In this document, the term "HVDC grids" is used. While this document focuses on requirements specific for HVDC grids, some requirements are considered applicable to all HVDC systems in general, i.e., including point-to-point HVDC systems. Existing IEC (e.g., IEC TR 63363-1 [1]), Cigre or other relevant documents have been used for reference as far as possible. Corresponding to electric power transmission applications, this document is applicable to high voltage systems, i.e., those having typically nominal DC voltages higher than 50 kV with respect to earth are considered in this document. NOTE While the physical principles of DC networks are basically voltage independent, the technical options for designing equipment get much wider with lower DC voltage levels, e.g. in the case of converters or switchgear. This document covers technical aspects of: • coordination of HVDC grid and AC systems, • HVDC grid characteristics, • HVDC grid control, • HVDC grid protection, • AC/DC converter stations, • HVDC grid installations, including DC switching stations and HVDC transmission lines, • studies and associated models, • testing. Beyond the scope of this document, the following content is proposed for future work: • DC/DC converter stations.

IEC 63322:2025 establishes security requirements of ME EQUIPMENT using high-activity SEALED RADIOACTIVE SOURCES, directly or indirectly, for medical treatment and other clinical procedures. ME EQUIPMENT containing SEALED RADIOACTIVE SOURCES that are defined as Category 1, 2 and 3 RADIOACTIVE SOURCES by IAEA are subject to this document. The object of this document is to specify requirements for the security of ME EQUIPMENT containing high-activity SEALED RADIOACTIVE SOURCES with the aim to minimize the risk of unauthorized access to the contained SEALED RADIOACTIVE SOURCES, and to serve as the basis for other standards. This document contains requirements for the MANUFACTURER of the ME EQUIPMENT and, separately, for the RESPONSIBLE ORGANIZATION regarding security at the location during use and storage. The requirements of this document apply when the SEALED RADIOACTIVE SOURCES are contained in the ME EQUIPMENT, i.e. from the time when the SEALED RADIOACTIVE SOURCES are inserted into the ME EQUIPMENT, during the INTENDED USE and when the ME EQUIPMENT is not being used for its INTENDED USE or taken out of regular use, until the equipment is being decommissioned, i.e. until all SEALED RADIOACTIVE SOURCES are permanently removed from the equipment.
