Electrical relays - Tests and measurements - Part 49: Long term stability of sealing
IEC 63522-49:2025 This part of IEC 63522 is used for testing all kinds of electrical relays and for evaluating their ability to perform under expected conditions of transportation, storage and all aspects of operational use. This document defines a standard test method for long term stability of sealing.
Relais électriques - Essais et mesurages - Partie 49: Stabilité à long terme de l’étanchéité
IEC 63522-49:2025 La présente partie de l'IEC 63522 traite des essais de tous les types de relais électriques et elle évalue leur aptitude à fonctionner dans les conditions prévues de transport, de stockage et dans tous les aspects de leur utilisation opérationnelle. Le présent document a pour objet de définir une méthode d'essai normalisée pour la stabilité à long terme de l’étanchéité.
Scope
1.1 General
1.1.1 These requirements cover Distributed Energy Resource Systems (DER systems) that contain
multiple DER units and associated control equipment that provide electrical energy to loads within the
DER system. The DER system may utilize one or more DER units of any type. DER systems may also
provide energy to the area EPS (Electric Power System) if present. This Standard…
Domaine d’application
1.1 Généralités
1.1.1 Ces exigences s’appliquent aux systèmes de ressources énergétiques distribuées (systèmes
RED) qui contiennent plusieurs unités de RED et l’équipement de commande connexe qui fournissent de
l’énergie électrique aux charges à l’intérieur du système RED. Le système RED peut utiliser une ou
plusieurs unités RED de n’importe quel type. Les systèmes RED…
Wind energy generation systems — Part 4: Design requirements for wind turbine gearboxes
This document 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 life…
Information technology — SoftWare Hash IDentifier (SWHID) Specification V1.2
This specification defines a standard data format for referencing software artifacts that match the data model of modern distributed version control systems.
This format includes the typical tree-like structure of a filesystem hierarchy, but also, special nodes to track revisions and releases, as well as the full status of a version control system, with all its development branches.
A key…
Information technology — Financial information exchange — Simple binary encoding
This document provides the normative specification of Simple Binary Encoding (SBE), which is one of the possible syntaxes for FIX messages, but not limited to FIX messages. The scope comprises the encoding (wire format) and the message schema for SBE.
