IEC 60773:2021 applies to test methods for the measurement of the operational characteristics of brushes designed to operate on commutating and slip ring machines under specified test conditions. By extension some tests may be relevant for other kinds of sliding electrical contacts for electrical appliances. This second edition cancels and replaces the first edition published in 1983. This…

ISO/IEC 14763-4:2021(E) specifies the measurement of two- and four-pair balanced cabling of a) end-to-end (E2E) link Class D, E and EA; b) modular plug terminated links (MPTLs) of Class D, E, EA, F, FA and of Class I and II; c) direct attach cabling of Class D, E, EA, F, FA and of Class I and II. The free connectors which terminate two and four pairs in field and laboratory conditions are…

IEC 62053-24:2020 applies only to static var-hour meters of accuracy classes 0,5S, 1S, 1, 2 and 3 for the measurement of alternating current electrical reactive energy in 50 Hz or 60 Hz networks and it applies to their type tests only. This document uses a conventional definition of reactive energy where the reactive power and energy is calculated from the fundamental frequency components of the…

IEC 62053-22:2020 applies only to transformer operated static watt-hour meters of accuracy classes 0,1 S, 0,2 S and 0,5 S for the measurement of alternating current electrical active energy in 50 Hz or 60 Hz networks and it applies to their type tests only. This document applies to electricity metering equipment designed to: • measure and control electrical energy on electrical networks (mains…

IEC 62053-23:2020 applies only to static var-hour meters of accuracy classes 2 and 3 for the measurement of alternating current electrical reactive energy in 50 Hz or 60 Hz networks and it applies to their type tests only. For practical reasons, this document is based on a conventional definition of reactive energy for sinusoidal currents and voltages containing the fundamental frequency only.…
