Space systems — Space-based services for a high accuracy positioning system with safety requirements
This document provides requirements and recommendation for space-based systems that, using satellite radionavigation services, provide high accuracy positioning of rovers. It is particularly intended for rovers whose operation requires meeting specific safety requirements, including in situations of low visibility. This document also provides methods to verify the system requirements, as well as…
Marine energy - Wave, tidal and other water current converters - Part 10: Assessment of mooring syst...
IEC TS 62600-10:2021 provide uniform methodologies for the design and assessment of mooring systems for floating Marine Energy Converters (MECs) (as defined in the TC 114 scope). It is intended to be applied at various stages, from mooring system assessment to design, installation and maintenance of floating Marine Energy Converters plants.
This document is applicable to mooring systems for…
Aéronautique et espace — Éléments de fixation borgnes, type fileté, à freinage interne — Méthode d&#...
Le présent document décrit la méthode d'essai de couple de freinage pour les éléments de fixation borgnes, de type fileté. Cette méthode d’essai est utilisée pour mesurer le couple de freinage des éléments de fixation borgnes à filetage intérieur et manchon externe. Elle s’applique aux éléments de fixation borgnes composés de quatre éléments (écrou d’entraînement, écrou, manchon et boulon…
Aéronautique et espace — Bague filetée, à freinage interne — Méthode d'essai de couple et de pr...
Le présent document décrit la méthode d'essai de couple et de précharge pour les bagues filetées. Cette méthode d’essai est utilisée pour mesurer le couple de freinage, le couple de freinage au démarrage après desserrage, la coupure de couple (torque off) et la précharge des bagues filetées.
Aerospace — Blind fasteners, threaded type, self-locking — Test method for locking torque
This document describes the locking torque test method for blind fasteners, threaded type. This test method is used to measure the locking torque of blind fasteners with internal thread and external sleeve. It is applicable to blind fasteners consisting out of four elements (drive nut, nut, sleeve and corebolt) having a cross recess at the top of the nut.
Aerospace — Collar, threaded, self-locking — Test method for torque and preload
This document describes torque and preload test method for threaded collars. This test method is used to measure the locking torque, breakaway torque, torque off and preload of threaded collars.
Photovoltaic system performance - Part 1: Monitoring
IEC 61724-1:2021 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.
IEC 61724-1:2021 outlines terminology, equipment, and methods for performance monitoring and analysis of photovoltaic…
Photovoltaic system performance - Part 1: Monitoring
IEC 61724-1:2021 outlines terminology, equipment, and methods for performance monitoring and analysis of photovoltaic (PV) systems. It also serves as a basis for other standards which rely upon the data collected. This document defines classes of photovoltaic (PV) performance monitoring systems and serves as guidance for monitoring system choices. This second edition cancels and replaces the…
