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 TR 63519:2024 provides information on terminology and general concepts in the determination of measurement uncertainties (MU). It focuses on application aspects based on the example of IEC TC 85 (Measuring equipment for electrical and electromagnetic quantities) and shows the opportunities and implications for further use of measurement uncertainties.
Measurement uncertainties are relevant for metrological compatibility and metrological traceability. Therefore, information on the role of measurement uncertainty in decisions or conformity assessments is given.
References to documents, standards and guidelines are made but only key results will be stated.

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 TS 63383:2022 deals with cybersecurity related to measuring devices (PMD according to IEC 61557-12 and PQI according to IEC 62586-1) and devices for data collection (devices according to IEC 62974-1) that are intended to be installed in restricted access areas.
This document deals with cybersecurity aspects (e.g. device hardening or device resilience) of device(s) used for power metering and monitoring, power quality monitoring, data collection and analysis, but does not cover requirements for organisational cybersecurity (e.g. end-user security policy).
This document is a first attempt to develop awareness by manufacturers and other relevant stakeholders about cybersecurity aspects and provide basic guidance for achieving the appropriate security mitigation against vulnerabilities to security threats:
– in coherence with device/system approaches described in relevant standards such as IEC 62443 (all parts) and ISO/IEC 27001,
– based on generic system use-cases.
This document does not cover billing meters covered by the IEC 62053-2x set of standards.
