This document specifies letter codes for designation of colours and provides rules for their combination to designate colour combinations. The letter codes are intended to be applied in the technical documentation of electrical installations, electrical equipment and products, and in markings of electrical equipment and products. This basic safety publication focusing on safety essential requirements 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 ISO/IEC Guide 51. It is not intended for use by manufacturers or certification bodies. One of the responsibilities of a technical committee is, wherever applicable, to make use of basic safety publications in the preparation of its publications. The requirements of this basic safety publication will not apply unless specifically referred to or included in the relevant publications. This document does not specify any requirements for the encoding of colour properties, nor for their visual representation. Such requirements are under the responsibility of the different technical committees.

IEC 61558-2-23:2024 is available as IEC 61558-2-23:2024 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 61558-2-23:2024 deals with the safety of transformers for construction sites and power supply units incorporating transformers for construction sites. Transformers incorporating electronic circuits are also covered by this document. This third edition cancels and replaces the second 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) adjustment of structure and references in accordance with IEC 61558-1:2017; b) new symbol for power supply units with linearly regulated output voltage. It has the status of a group safety publication in accordance with IEC Guide 104.

IEC 61846:2025 is applicable to: – therapy equipment using extracorporeally induced focused pressure pulse waves; – therapy equipment producing focused mechanical energy excluding thermal energy. This document does not apply to percutaneous and laser lithotripsy equipment. This document does not apply to: – histotripsy or other therapeutic ultrasound bursts of longer time duration than that of the pressure pulse; – non-focused pressure pulse equipment. This document specifies: – measurable parameters which could be used in the declaration of the acoustic output of extracorporeal focused pressure pulse equipment; – methods of measurement and characterization of the pressure field generated by focused pressure pulse equipment. While this document has been developed for equipment intended for use in lithotripsy, it has been developed such that, as long as no other specific standards are available to be used for other medical applications of therapeutic extracorporeal focused pressure pulse equipment, this document can be used as a guideline. IEC 61846:2025 cancels and replaces the first edition published in 1998. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Change of title: "pressure pulse lithotripters" in the previous edition is changed to "therapeutic focused short pressure pulse sources" in order to take into account the development in the relevant technical and biomedical applications of such sources, which were originally used only for (kidney) lithotripsy, while recent applications include a wide range for the treatment of, for example, stone diseases, orthopaedic pain, tissue, cardiac and brain diseases. The term "focused" was added to differentiate IEC 61846 from IEC 63045. The term "short" was added to align the nomenclature to IEC 63045 and to differentiate IEC 61846 from standards in the HIFU and HITU fields. b) Clause 1 and elsewhere in the document: The term "lithotripsy" is changed to "therapy" in order to account for the wide range of applications beyond stone diseases. c) Clause 3: The "−6 dB" parameter definitions are replaced by "−n dB" to avoid misconceptions in the significance and use of these parameters and to account for newer findings in literature. Additional "n MPa" parameters are introduced for the same reasons. The definitions of "derived" parameters are aligned to those in recently published standards, for example IEC 62127-1. New definitions were added which describe parameters appearing in newer relevant literature, for example "momentum", "average positive acoustic pressure", "cavitation induction index", "pulse to pulse variability", "total pressure pulse energy dose". d) Clause 6: The terms "focus hydrophone" and "field hydrophone" were removed to account for newer technical developments. New terms distinguish between "hydrophones for pressure pulse measurements" and "hydrophones for quality assurance". e) Annexes: Descriptions, tables and figures were edited to account for newer literature and standards as well as technical developments.

IEC 61987-100:2025 provides the semantics of the data needed for the area of process automation, the Industrial Internet of Things (IIoT), and smart manufacturing. Classification and description of products with classes and properties for future objects within the scope of TC 65 (Industrial-process measurement, control and automation) will be developed as IEC 61987 DB standard and published via IEC CDD data dictionary IEC 61987.
