IEC TR 63385-1:2023 provides a catalogue of the architecture and principles of measurement of short-range radars that are widely exploited in civil applications. The applications are related to the detection of the target for obstacle avoidance, motion sensing, or identification of devices. The mass civil use of radars sometimes creates compatibility issues among the services. The performance of…

IEC TS 62898-2:2018+AMD1:2023 provides guidelines for operation of microgrids. Microgrids considered in this document are alternating current (AC) electrical systems with loads and distributed energy resources (DER) at low or medium voltage level. This document does not cover direct current (DC) microgrids. IEC TS 62898-2 applies to operation and control of microgrids, including: - operation…

IEC 62506:2023 provides guidance on the application of various accelerated test techniques for measurement or improvement of item reliability. Identification of potential failure modes that can be experienced in the use of an item and their mitigation is instrumental to ensure dependability of an item. The object of the methods is to either identify potential design weakness or provide…

L'IEC 62506:2023 fournit des recommandations pour l’application de diverses techniques d’essais accélérés permettant de mesurer ou d’améliorer la fiabilité de l’entité. L’identification des modes de défaillance potentiels qui peuvent être rencontrés lors de l’utilisation d’une entité donnée et la manière d’y remédier contribuent à assurer la sûreté de fonctionnement d’une entité. L’objectif…

This document specifies the test methods to be used for characterizing an entire generating set. It applies to alternating current (AC) generating sets driven by reciprocating internal combustion (RIC) engines for land and marine use, excluding generating sets used on aircraft or to propel land vehicles and locomotives. This document also provides simulation methods as an alternative method for…

Le présent document spécifie les méthodes d'essai relatives aux caractéristiques d'un groupe électrogène complet. Il s’applique aux groupes électrogènes à courant alternatif (CA), entraînés par moteurs alternatifs à combustion interne (RIC), utilisés pour des applications terrestres et marines, à l'exclusion des groupes électrogènes utilisés à bord des aéronefs ou pour la…

This document specifies technical requirements for independent glazed openings on large yachts, taking into account navigation conditions, the location of the opening and the materials, framing and testing. Large yachts are yachts with length of the hull, LH, higher or equal to 24 m, used for sport or pleasure and commercial operations. This document is suitable for the design of glazed openings…

This document provides an overview of the methods used to determine the nanoparticle number concentration in liquid dispersions and aerosols. The methods described are the ensemble measurement techniques of differential centrifugal sedimentation (DCS), multi-angle dynamic light scattering (MDLS), small-angle X-ray scattering (SAXS) and ultraviolet-visible spectroscopy (UV-vis) and the particle…
