IEC 6033:2019 defines terms for high-voltage direct current (HVDC) power transmission systems and for HVDC substations using electronic power converters for the conversion from AC to DC or vice versa. This document is applicable to HVDC substations with line commutated converters, most commonly based on three-phase bridge (double way) connections (see Figure 2) in which unidirectional electronic…

IEC 60633:2019 définit les termes relatifs aux systèmes de transport de puissance en courant continu à haute tension (CCHT), et aux postes CCHT utilisant des convertisseurs électroniques de puissance pour la conversion du courant alternatif en courant continu ou inversement. Le présent document est applicable aux postes CCHT avec des convertisseurs commutés par le réseau, fondés le plus souvent…

IEC 60086-4:2019 specifies tests and requirements for primary lithium batteries to ensure their safe operation under intended use and reasonably foreseeable misuse. NOTE Primary lithium batteries that are standardized in IEC 60086-2 are expected to meet all applicable requirements herein. It is understood that consideration of this part of IEC 60086 might also be given to measuring and/or…

IEC 60086-4:2019 spécifie les essais et les exigences pour les piles électriques au lithium afin d’assurer leur fonctionnement en toute sécurité dans les conditions d’utilisation prévue et en cas de mauvais usage raisonnablement prévisible. NOTE Les piles électriques au lithium qui sont normalisées dans l'IEC 60086-2 sont prévues pour satisfaire à toutes les exigences applicables ci-dessous…

IEC 60193:2019 applies to laboratory models of any type of impulse or reaction hydraulic turbine, storage pump or pump-turbine. This document applies to models of prototype machines either with unit power greater than 5 MW or with reference diameter greater than 3 m. Full application of the procedures herein prescribed is not generally justified for machines with smaller power and size.…

IEC 60193:2019 est applicable aux modèles de laboratoire de tout type de turbine hydraulique à action ou à réaction, de pompe d'accumulation ou de pompe-turbine. Il s'applique aux modèles de machines prototypes ayant une puissance unitaire supérieure à 5 MW ou un diamètre de référence supérieur à 3 m. Bien que l'application intégrale des procédures prescrites ne soit généralement…

IEC 61158-3-12:2019 defines the services provided to the Type 12 fieldbus application layer at the boundary between the application and data-link layers of the fieldbus reference model and systems management at the boundary between the data-link layer and systems management of the fieldbus reference model. This fourth edition cancels and replaces the third edition published in 2014. It…

IEC 61158-3-19:2019 defines the services provided to the Type 19 fieldbus application layer at the boundary between the application and data-link layers of the fieldbus reference model and systems management at the boundary between the data-link layer and systems management of the fieldbus reference model. This fourth edition cancels and replaces the third edition published in 2014. It…

IEC 61158-3-4:2019 defines the services provided to the Type 4 fieldbus application layer at the boundary between the application and data-link layers of the fieldbus reference model and systems management at the boundary between the data-link layer and systems management of the fieldbus reference model. This third edition cancels and replaces the second edition published in 2014. It constitutes…

IEC 61158-3-21:2019 defines in an abstract way the externally visible service provided by the Type 21 fieldbus data-link layer in terms of the primitive actions and events of the service; the parameters associated with each primitive action and event, and the form which they take and the interrelationship between these actions and events, and their valid sequences. It cancels and replaces the…
