IEC 60728-1-1:2014 is applicable to RF cabling for two-way home networks with wired cords or wireless links inside a room and primarily intended for television and sound signals operating between about 5 MHz and 3 000 MHz. The frequency range is extended to 6 000 MHz for distribution techniques that replace wired cords with a wireless two-way communication. This second edition cancels and replaces the first edition published in 2010, and constitutes a technical revision. It includes the following changes: update of performance requirements in Clause 5 to include those for DVB-T2 signals.

IEC 62974-1:2024 specifies product and performance requirements for devices that fall under the heading of "monitoring and measuring systems used for data collection, aggregation and analysis", for industrial, commercial, and similar use rated below or equal to 1 kV AC and 1,5 kV DC. These devices are fixed and are intended to be used indoors as panel-mounted devices, or as modular devices fixed on a DIN rail, or as housing devices fixed on a DIN rail, or as devices fixed by other means inside a cabinet. These devices are used to upload or download information (energy measured on loads, power metering and monitoring data, temperature information, etc.), mainly for energy efficiency purposes. These devices are known as energy servers (ESE), energy data loggers (EDL), data gateways (DGW) and I/O data concentrators (IODC) and are grouped together under the family name of Data Management Devices (DMD). This document does not cover: • devices used only in the consumer market (living quarters) or household; • devices used in the smart metering infrastructure (e.g. smart meters); • devices used in the smart grid infrastructure; • devices used as IT servers in the information technology business; • power metering and monitoring devices (PMD); • I/O data concentrators already covered by a specific product standard; • communication protocols and interoperability; • power quality instruments (PQI); • software used for the data collection and analysis of the power quality for the supply side. IEC 62974-1:2024 cancels and replaces the first edition published in 2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the performance criteria have been reviewed; b) EMC and safety requirements have been improved; c) mechanical requirements have been clarified and amended.

IEC 60688:2024 applies to transducers (TRD) with electrical inputs and outputs for making measurements of AC or DC electrical quantities. The output signal can be in the form of an analogue or digital signal. This document applies to measuring transducers used for converting electrical quantities such as: – current, – voltage, – active power, – reactive power, – power factor, – phase angle, – frequency, – harmonics or total harmonic distortion, – apparent power, and – DC power to an output signal. This document applies a) if the fundamental frequency of the input(s) lies between 0 Hz and 1 500 Hz, b) to the electrical measuring transducer if it is part of a system for the measurement of an electrical or non-electrical quantity, c) to transducers for use in a variety of applications such as telemetry and process control and in one of a number of defined environments. This document is not applicable for: – instrument transformers that comply with IEC 61869 (all parts), – transmitters for use in an industrial process application that comply with IEC 60770 (all parts), – power metering and monitoring devices (PMD) that comply with IEC 61557-12, – meters that comply with the IEC 62053 series, – handheld sensors, – residual current monitoring devices (RCMs) that comply with IEC 62020-1, – residual current detecting devices (RDC-DD) that comply with IEC 62955, – in-cable control and protection devices (IC-CPDs) that comply with IEC 62752, – modular residual current devices (MRCDs) that comply with IEC 60947 2:2016/AMD1:2019, Annex M. Within the measuring range, the output signal is a function of the measurand. An auxiliary supply can be required. This document is intended: – to specify the terminology and definitions relating to transducers whose main application is in industry, – to unify the test methods used in evaluating transducer performance, – to specify accuracy limits and output values for transducers. IEC 60688:2024 cancels and replaces the fourth edition published in 2021. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) updating normative references; b) updating definitions; c) updating structure; d) adding DC power measurement.

IEC 62683-2:2024 specifies the functional safety and reliability data model descriptions for low‑voltage switchgear and controlgear to be used by engineering tools for the design of safety related control systems according to IEC 62061, IEC 61508-2 and ISO 13849-1, and for dependability analysis of electrotechnical systems. This dictionary is used to facilitate the exchange between computers of data characterizing low-voltage switchgear and controlgear. Each property has an unambiguously defined meaning and naming, and where relevant, a defined value list, a defined format and a defined unit. The data models described in this document are intended to complement the product catalogue data defined by IEC 62683-1. This document does not cover: - exchange format such as defined in VDMA 66413, - explosive atmosphere applications, - manufacturer specific features.
