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.

This edition includes the following significant technical changes with respect to IEC TS 61400‑3-2: a) The relevant contents of IEC 61400-3-1 have been migrated into IEC 61400-3-2, making IEC 61400-3-2 a self-standing document that does not have to be read directly in conjunction with IEC 61400-3-1. b) Several modifications have been made regarding metocean conditions in Clause 6 considering the nature of FOWT and the offshore site where FOWT will be installed, including: (1) the importance of wave directional spreading has been highlighted as it may result in larger loads for FOWT, including the addition of the new informative Annex O and Annex P and (2) the characteristic of swell has been explained, which may be relevant for some FOWT projects, including the addition of new informative Annex R regarding the characteristic of swell. c) Subclauses 7.1, 7.2, 7.3, 7.4 and 7.5 have been changed to include a revised DLC table and its related descriptions, including amongst others updated requirements on directionality, wave conditions, redundancy check and damage stability cases, and a robustness check case; further updates are made related to guidance and necessities provided on load calculations and simulation requirements. d) Subclause 7.6 has been updated with guidance on fatigue assessment along with clarifications on serviceability analysis and the applicable material for WSD; related Annex L has been updated and a new Annex M has been added for clarification of the safety factors and load and load effect approach for floating substructures e) The concept of floater control system that will interact with the wind turbine controller has been introduced in Clause 8. f) Clause 11 has been renamed from "Foundation and substructure design" to "Anchor design" and requirements for the transient conditions have been added. g) A more detailed clause regarding concrete design has been added to Clause 16 together with an informative Annex Q. h) Clause 15 has been updated with the aim to improve ease of use, using experience from oil and gas and considering unique wind turbine characteristics; updates included guidance for TLPs, damage stability, dynamic stability, testing and the addition for Annex S regarding how to analyse collision probability.

IEC 62813:2025 specifies the electrical characteristics (capacitance, internal resistance, discharge accumulated electric energy, and voltage maintenance rate) test methods of lithium-ion capacitors (LIC) for use in electric and electronic equipment. This edition includes the following significant technical changes with respect to the previous edition: a) The document has been restructured to comply with the ISO/IEC Directives, Part 2.

These particular requirements apply to single unit electric tumble dryers for household and similar use intended for placing on the floor against a wall, for building-in or placing under a counter, a kitchen worktop or under a sink, for wall-mounting or on a counter. This standard is also applicable for gas-fired electric tumble dryers

Scope unchanged, see EN61121:2013

IEC 80601-2-71:2025 applies to the BASIC SAFETY and ESSENTIAL PERFORMANCE of FUNCTIONAL NIRS EQUIPMENT, as defined in 201.3.205, intended to be used by itself, or as a part of an ME SYSTEM hereinafter referred to as ME EQUIPMENT. HAZARDS inherent in the intended physiological function of ME EQUIPMENT or ME SYSTEMS within the scope of this document are not covered by specific requirements in this document except in IEC 60601-1:2005, IEC 60601-1:2005/AMD1:2012 and IEC 60601-1:2005/AMD2:2020, 7.2.13 and 8.4.1. This document is not applicable to – equipment for the measurement of oxygen saturation of the haemoglobin in the micro vessels (capillaries, arterioles and venules), i.e. tissue oximeters; – frequency-domain and time-domain equipment for functional near-infrared spectroscopy; – equipment for the measurement of changes in the concentration of chromophores other than oxy- and deoxy-haemoglobin; – equipment for the measurement of changes in the concentration of oxy- and deoxy-haemoglobin in tissues other than the brain. This document does not specify the requirements for: – cerebral tissue oximeter equipment, which are given in ISO 80601-2-85; and – pulse oximeter equipment, which are given in ISO 80601-2-61. IEC 80601-2-71:2025 cancels and replaces the first edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) alignment with IEC 60601-1:2005, IEC 60601-1:2005/AMD1:2012, IEC 60601-1:2005/AMD2:2020, IEC 60601-1-8:2006, IEC 60601-1-8:2006/AMD1:2012, IEC 60601-1-8:2006/AMD2:2020, IEC 60601-1-2:2014, IEC 60601-1-2:2014/AMD1:2020, IEC 60601-1-6:2010, IEC 60601-1-6:2010/AMD1:2013 and IEC 60601-1-6:2010/AMD2:2020; b) added requirements for ESSENTIAL PERFORMANCE; c) added requirements for PRIMARY OPERATING FUNCTIONS; d) added requirements for protection against excessive temperatures; e) added requirements for the display legibility for OPERATORS wearing personal protective equipment; f) harmonization with ISO 20417, where appropriate.

IEC 62127-2:2025 specifies: - absolute hydrophone calibration methods; - relative (comparative) hydrophone calibration methods. Recommendations and references to accepted literature are made for the various relative and absolute calibration methods in the frequency range covered by this document. This document is applicable to - hydrophones used for measurements made in water and in the ultrasonic frequency range 50 kHz to 100 MHz; - hydrophones employing piezoelectric sensor elements, designed to measure the pulsed wave and continuous wave ultrasonic fields generated by ultrasonic equipment; - hydrophones with or without a hydrophone pre-amplifier. IEC 62127-2:2025 cancels and replaces the first edition published in 2007, Amendment 1:2013 and Amendment 2:2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the upper frequency limit of 40 MHz has been removed; b) hydrophone sensitivity definitions have been changed to recognize sensitivities as complex-valued quantities; c) directional response measurement and effective size determination procedures have been updated in 12.5.1 to align with recent changes in IEC 62127-3; d) Annex F has been amended to comprise a calibration technique for high-frequency complex-valued calibration; e) the reciprocity method description in Annex K was extended to also comprise focusing transducers.
