IEC 62751-1:2014+A1:2018 sets out the general principles for calculating the power losses in the converter valves of a voltage sourced converter (VSC) for high-voltage direct current (HVDC) applications, independent of the converter topology. Several clauses in the standard can also be used for calculating the power losses in the dynamic braking valves (where used) and as guidance for calculating…

L'IEC 62751-1:2014+A1:2018 définit les principes généraux de calcul des pertes de puissance dans les valves à convertisseur de source de tension (VSC) pour des applications en courant continu à haute tension (CCHT), quelle que soit la topologie du convertisseur. Plusieurs articles de la norme peuvent également être utilisés pour calculer les pertes de puissance dans les valves à freinage…

ISO/TR 27918:2018 is designed to be an information resource for the potential future development of a standard for overall risk management for CCS projects. The risks associated with any one stage of the CCS process (capture, transportation, or storage) are assumed to be covered by specific standard(s) within ISO/TC 265 and other national and/or international standards. For example, the risks…

ISO 20579-4:2018 identifies information to be reported in a datasheet, certificate of analysis, report or other publication regarding the handling of nano-objects in preparation for surface chemical analysis. This information is needed to ensure reliability and reproducibility of analyses needed to advance research and technology using these materials, and for obtaining appropriate understanding…

IEC 60335-2-114:2018 deals with the electrical safety of self-balancing personal transport devices for use with batteries containing alkaline or other non-acid electrolytes. Appliances not intended for normal household use but which nevertheless may be a source of danger to the public, such as appliances intended to be used by laymen in shops, in light industry and on farms, are within the scope…

L'IEC 60335-2-114:2018 traite de la sécurité électrique des dispositifs de transport personnel autoéquilibrés comportant des accumulateurs alcalins ou autres accumulateurs à électrolyte non acide. Les appareils non destinés à un usage domestique normal mais qui néanmoins peuvent constituer une source de danger pour le public, tels que les appareils destinés à être utilisés par des usagers…

ISO 21188:2018 sets out a framework of requirements to manage a PKI through certificate policies and certification practice statements and to enable the use of public key certificates in the financial services industry. It also defines control objectives and supporting procedures to manage risks. While this document addresses the generation of public key certificates that might be used for…
