IEC 61000-3-2:2018 deals with the limitation of harmonic currents injected into the public supply system. It specifies limits of harmonic components of the input current which can be produced by equipment tested under specified conditions. It is applicable to electrical and electronic equipment having a rated input current up to and including 16 A per phase, and intended to be connected to public…

ISO 11195:2018 specifies requirements for the performance and safety of stand-alone gas mixers intended for mixing oxygen with another gas for medical use. ISO 11195:2018 does not apply to: a) blocks of flowmeters with separate controls for the flow of each gas; b) stand-alone gas mixers which mix oxygen with ambient air; c) stand-alone gas mixers with more than two different gas inlets; d…

IEC 62561-6:2018 specifies the requirements and tests for devices intended to count the number of lightning strikes based on the current flowing in a conductor. This conductor may be part of a lightning protection system (LPS) or connected to an SPD installation or other conductors, which are not intended to conduct a significant portion of lightning currents. LSCs may also be suitable for use…

IEC 62731:2018(E) specifies the text-to-speech functionality for a (broadcast) receiver with a text-to-speech system. Such a system may be one device, i.e. a receiver with an integrated text-to-speech generator, or may be two devices, i.e. a receiver interfacing with an external text-to-speech device. This document applies only to completely functional stationary (or semi-stationary) digital TV…
