l'IEC 60034-3:2020 s'applique aux alternateurs triphasés synchrones de grande taille, de puissance assignée supérieure ou égale à 10 MVA, entraînés par des turbines à vapeur ou par des turbines à gaz. Elle inclut également les compensateurs Mvar synchrones de même puissance connectés à un réseau, destinés à échanger de la puissance réactive. Le présent document constitue un complément…

IEC 61169-63:2020 which is a sectional specification (SS), provides information and rules for the preparation of detail specifications (DS) for RF coaxial connectors which can preferably be used with RF cables 60096 IEC 50-3 of IEC 60096-2. These connector patterns are for low power, quick connect/disconnect applications using a bayonet type coupling mechanism and are commonly known as type…

IEC 60664-1:2020 deals with insulation coordination for equipment having a rated voltage up to AC 1 000 V or DC 1 500 V connected to low-voltage supply systems. This document applies to frequencies up to 30 kHz. It applies to equipment for use up to 2 000 m above sea level and provides guidance for use at higher altitudes. It provides requirements for technical committees to determine clearances…

L’IEC 60664-1:2020 traite de la coordination de l'isolement des matériels ayant une tension assignée allant jusqu’à 1 000 V en courant alternatif ou jusqu’à 1 500 V en courant continu connectés aux réseaux d’énergie électrique à basse tension. Le présent document s’applique aux fréquences jusqu’à 30 kHz inclus. Il s'applique au matériel utilisé jusqu'à 2 000 m au-dessus du niveau…

This document gives the dimensions of, and specifies the contact allocation and tests and test requirements for, 15-pole connectors for the electrical connection of equipment other than braking systems and running gear of towing and towed vehicles with 24 V nominal supply voltage. It specifies a park socket used to receive and store the plug when disconnected, and a means of adaptation between 7-…

This document specifies the technical delivery conditions for corrosion-resistant alloy seamless tubular products for casing, tubing, coupling stock and accessory material (including coupling stock and accessory material from bar) for two product specification levels: — PSL-1, which is the basis of this document; — PSL-2, which provides additional requirements for a product that is…

The document gives guidance for managing healthcare service security using connectable personal health devices. This document considers unidirectional data uploading from the PHD to the gateway (manager device), however, there are many clinical use cases for bidirectional data exchange. This document is applicable to identification and authentication between the bidirectionally connected PHDs and…

This document specifies terms and definitions that are related to air quality (see 3.1.1.1). These are either general terms or are used in connection with the sampling (see 3.3.3.1) and measurement of gases, vapours (see 3.1.5.8) and airborne particles (see 3.2.2.1) for the determination of air quality. The terms included are those that have been identified as being fundamental because their…

IEC 62496-4-214: 2020 defines the standard interface dimensions for a terminated waveguide optical circuit board (OCB) assembly (referred to simply as "assembly") using single-row thirty-two-channel connectors for polymer waveguides connected with a symmetric PMT connector.
