Information technology - Biometric sample quality - Part 5: Face image data
This document establishes requirements on implementations that quantify how a face image’s properties conform with those of canonical face images, for example those specified in ISO/IEC 39794-5:2019, Clause D.1, for three use-cases:
1) collection of reference samples for ID documents;
2) sample system enrolment; and
3) probes for instantaneous response.

Wind energy generation systems - Part 4: Design requirements for wind turbine gearboxes
IEC 61400-4:2025 is applicable to enclosed speed increasing gearboxes for horizontal axis wind turbine drivetrains with a power rating in excess of 500 kW. This document applies to newly designed gearboxes for wind turbines installed onshore or offshore. The technical requirements given in this document are not intended for repaired or refurbished gearboxes, or for the extension of the service…
Railway infrastructure — Rail fastening systems — Two directional test method for resistance to repe...
This document describes a test procedure for the determination of resistance to repeated loading by – amongst others – applying out-of-phase load cycles which generate forces in two directions, representative of those caused by traffic on railway track, taking into account the effect of two consecutive axles of passing railway vehicles.
Space systems — Structural design — Loads and induced environment
This document defines the principles used to determine loads and the induced environment during the service life of a space system and its components, taking account of the notions of probability, combined loads, corresponding safety factors and life cycle.
