IEC 60761-2:2026 is applicable to equipment intended for simultaneous, delayed or discrete sequential measurement of aerosols in gaseous effluents discharged into the environment.
It is applicable to equipment designed to fulfil the following functions:
- the measurement of the volumetric activity (Bq/m3) of the aerosols in either gaseous effluents or the released total activity of aerosols (Bq), or both;
- the actuation of an alarm signal when either a predetermined volumetric activity or a predetermined total released activity of aerosols is exceeded.
This equipment is intended for measurement over a wide range of activity, including very small quantities in the presence of a much larger natural background. The daughters of 222Rn (radon) and 220Rn (thoron) are naturally occurring aerosols contributing to the natural background.
The objective of this document is to establish specific standard requirements, including technical characteristics and general test conditions, and to give examples of acceptable methods for aerosol effluent monitors.

IEC SRD 63347-2:2026 describes and analyses a comprehensive set of high-level scenarios of how smart cities can best respond to public health emergencies, and strengthen their “Urban Immune System”, using evidence from as many countries as possible. It covers use cases related to the prevention, the control and the successful ending of public health emergencies, and to dealing with the longer-term harm that these may cause.

IEC 63522-41:2026 provides guidelines for the insulation coordination of electromechanical elementary, solid state, time, forcibility guided and reed relays as well reed contacts and hybrid switching solutions. This document can also be used for similar devices when specified in a detail specification.

IEC TS 63529:2026, which is a Technical Specification, is intended to inform and guide the harmonic design of the DC side of HVDC projects. It considers all aspects of AC current and voltage occurring on the DC circuit and also the interaction with adjacent systems.
The switching action in HVDC converters results in a wide spectrum of harmonics. These range from the fundamental frequency to the radio frequency range. Traditionally the specification of DC side harmonic performance has been limited to the frequency range of interest for induced audible noise on nearby telephone systems. Often a limit of 50th harmonic has been applied, corresponding to 2 500 Hz or 3 000 Hz on 50 Hz and 60 Hz systems respectively. Occasionally the range has been extended to 5 000 Hz. This frequency range has corresponded to the spectrum of characteristic harmonic generation from thyristor line commutated converters (LCC).
The introduction of HVDC voltage sourced converters (VSC) has meant that although the magnitude of DC side harmonic generation from these converters is generally lower, the generated spectrum of interest extends to higher frequencies.
The scope of this document therefore covers the frequency range up to approximately 5 000 Hz. Higher frequencies are mentioned only when relevant. The scope excludes the much higher frequency ranges appropriate to PLC communication and the radio interference spectra.
