NOTE: For…

1 Domaine d’application 1.1 Ces exigences couvrent : a) les compteurs pour liquides inflammables et combustibles, du type et de la taille couramment utilisés dans l’assemblage des dispositifs de distribution de carburant pour moteurs; et b) les compteurs de gaz de pétrole liquéfié (GPL), du type et de la taille couramment utilisés dans l’assemblage des appareils de distribution de carburant…

IEC 60092-503:2021(E) is applicable to AC supply systems with voltages from 1 kV up to and including 36 kV. The requirements contained in other parts of the IEC 60092 series apply where appropriate, subject to the exceptions stated in the clauses of this document.

IEC 60891:2021 defines procedures to be followed for temperature and irradiance corrections to the measured I-V (current-voltage) characteristics (also known as I-V curves) of photovoltaic (PV) devices. It also defines the procedures used to determine factors relevant to these corrections. Requirements for I-V measurement of PV devices are laid down in IEC 60904-1 and its relevant subparts. This…

IEC 60891:2021 définit des procédures à suivre pour les corrections en fonction de la température et de l'éclairement appliquées aux caractéristiques I-V (courant-tension) mesurées (également appelées courbes I-V) des dispositifs photovoltaïques (PV). Il définit également les procédures utilisées pour déterminer les facteurs appropriés pour ces corrections. Les exigences pour le mesurage I-V…

IEC 61970-452:2021 defines the subset of classes, class attributes, and associations from the CIM necessary to execute state estimation and power flow applications between control centres and/or control centre components, such as power systems applications. The North American Electric Reliability Council (NERC) Data Exchange Working Group (DEWG) Common Power System Modelling group (CPSM)…

IEC 61970-452:2021 définit le sous-ensemble des classes, des attributs de classe et des associations du CIM nécessaires à l’exécution des applications d’estimation d’état et de flux d’énergie. Le groupe Common Power System Modeling (CPSM) de Data Exchange Working Group (DEWG) du North American Electric Reliability Council (NERC) a établi les premières exigences relatives aux données, présentées à…

This document specifies the accelerated ageing test and requirements for electrochromic glazings intended to either control direct or indirect solar transmission, or both. The electrochromic glazings can be assembled as insulating glass unit, laminated glass or combination of both. The test method described in this document is only applicable to chromogenic glazings that can be switched between…

This document specifies requirements for, and gives guidance on, the design and use of a traceability system in a rare earth supply chain. It specifies the information to be recorded by supply chain businesses for rare earth materials or products passing through the supply chain from mine to separated products.
