IEC TR 63410:2023, which is a Technical Report, aims to prepare a road map for categorizing Decentralized Electrical Energy Systems and identifying gaps in the existing standards relevant to Decentralized Electrical Energy Systems. The task of IEC Subcommittee 8B is to develop IEC publications enabling the development of secure, reliable and cost-effective systems with decentralized management…
Lightning protection system components (LPSC) - Part 1: Requirements for connection components
IEC 62561-1:2023 specifies the requirements and tests for metallic connection components that form part of a lightning protection system (LPS). Typically, these can be connectors, clamps, bonding and bridging components, expansion pieces and test joints. This third edition cancels and replaces the second edition published in 2017. This edition constitutes a technical revision. This edition…
Acoustics — Normal equal-loudness-level contours
This document specifies combinations of sound pressure levels and frequencies of pure continuous tones which are perceived as equally loud by human listeners. The specifications are based on the following conditions:
a)Â Â Â the sound field in the absence of the listener consists of a free progressive plane wave;
b)Â Â Â the source of sound is directly in front of the listener;
c)   the sound…

IEC 63287-2:2023 gives guidelines for the development of reliability qualification plans using the concept of mission profile, based on the environmental conditioning and proposed usage of the product. This document is not intended for military- and space-related applications.
Wind energy generation systems - Part 21-2: Measurement and assessment of electrical characteristics...
IEC 61400-21-2:2023 defines and specifies the quantities that are determined to characterize the electrical characteristics of grid-connected power plants (PPs).
This document defines the measurement and test procedures for quantifying the electrical characteristics as basis for the verification of compliance of PPs. This document defines a uniform functionality test and measurement procedure…
Industrial networks - Profiles - Part 2-3: Additional real-time fieldbus profiles based on ISO/IEC/I...
IEC 61784-2-3:2023 defines extensions of Communication Profile Family 3 (CPF 3) for Real-Time Ethernet (RTE). CPF 3 specifies a set of Real-Time Ethernet (RTE) communication profiles (CPs) and related network components based on the IEC 61158 series (Type 10), ISO/IEC/IEEE 8802-3 and other standards.
For each RTE communication profile, this document also specifies the relevant RTE performance…
