Railway applications — Track geometry quality — Part 1: Characterization of track geometry and track...
This document defines track geometry parameters and specifies the minimum requirements for track geometry measurements and the evaluation method for track geometry quality.
This document is applicable to 1 435 mm and wider track gauges. The urban/light rail systems, tramways and any track gauge narrower than 1 435 mm are excluded from the scope of this document, however it can be used as a…
Non-destructive testing — Characterization and verification of ultrasonic phased array equipment — P...
This document specifies the functional characteristics of multi-channel ultrasonic phased array instruments used for array probes and provides methods for their measurement and verification.
This document is also applicable to ultrasonic phased array instruments in automated systems; but other tests can be needed to ensure satisfactory performance. When the phased array instrument is a part of an…

Wind energy generation systems - Part 50: Wind measurement - Overview
IEC 61400-50:2022 provides a general introduction to the options that are available for wind measurement, which are further detailed in the other parts of the IEC 61400-50 series. Whereas those other standards define use-cases for wind measurements, the IEC 61400-50 series sets those wind measurement requirements which are independent of the use-case. Its purpose is to ensure that wind…
Fibre optic interconnecting devices and passive components - Connector optical interfaces for single...
IEC 61755-2-1:2022 defines a set of prescribed conditions for a single-mode fibre optic connection that is maintained in order to satisfy the requirements of attenuation and return loss (RL) performance in a randomly mated pair of non-angled polished physically contacting (PC) fibres. The model uses a Gaussian distribution of light intensity over the specified mode field diameter (MFD) for…
Generic smart grid requirements - Part 1: Specific application of the use case methodology for defin...
IEC SRD 62913-1:2022 (E) describes a common approach for IEC technical committees to define generic smart grid requirements for further standardization work. It uses as input the use case methodology defined as part of the IEC 62559 series, and provides a more detailed methodology for describing use cases and extracting requirements from these use cases. This will achieve a consistent and…
