IEC 62351-7:2017 defines network and system management (NSM) data object models that are specific to power system operations. These NSM data objects will be used to monitor the health of networks and systems, to detect possible security intrusions, and to manage the performance and reliability of the information infrastructure. The goal is to define a set of abstract objects that will allow the…

ISO 12354-2:2017 specifies calculation models designed to estimate the impact sound insulation between rooms in buildings, primarily using measured data which characterize direct or indirect flanking transmission by the participating building elements and theoretically-derived methods of sound propagation in structural elements. A detailed model is described for calculation in frequency bands, in…

ISO 12354-4:2017 specifies a calculation model to estimate the sound power level radiated by the envelope of a building due to airborne sound inside that building, primarily by means of measured sound pressure levels inside the building and measured data which characterize the sound transmission by the relevant elements and openings in the building envelope. These sound power levels, together…

IEC 61000-4-12:2017 relates to the immunity requirements and test methods for electrical and electronic equipment, under operational conditions, to ring waves occurring in low-voltage power, control and signal lines supplied by public and non-public networks. The object of this document is to establish a common reference for evaluating the immunity of electrical and electronic equipment when…

ISO 12354-1:2017 specifies calculation models designed to estimate the airborne sound insulation between adjacent rooms in buildings, primarily using measured data which characterize direct or indirect flanking transmission by the participating building elements, and theoretically-derived methods of sound propagation in structural elements. A detailed model is described for calculation in…

ISO 12354-3:2017 specifies a calculation model to estimate the sound insulation or the sound pressure level difference of a façade or other external surface of a building. The calculation is based on the sound reduction index of the different elements from which the façade is constructed and it includes direct and flanking transmission. The calculation gives results which correspond approximately…

ISO 18566-2:2017 dry cooling only surfaces with an air gap between construction and the emitter (not embedded) with or without an insulation fed with water at temperatures below 120 °C connected with a centralized heating and/or cooling supply source intended to be installed in buildings. Ceiling mounted radiant panels covered by this document are limited to a width from 0,3 m up to 1,5 m. ISO…

IEC 62683-1:2017 establishes the reference dictionary of the general description of low-voltage switchgear and controlgear classes based on defined properties. This dictionary is used to facilitate the exchange in electronic format of data describing low-voltage switchgear and controlgear. This document provides clear and unambiguous definitions of a limited number of properties and classes…

ISO/TS 11888:2017 describes methods for the characterization of mesoscopic shape factors of multiwall carbon nanotubes (MWCNTs). Techniques employed include scanning electron microscopy (SEM), transmission electron microscopy (TEM), viscometry, and light scattering analysis. ISO/TS 11888:2017 also includes additional terms needed to define the characterization of static bending persistence length…

IEC 62481-5:2017 ,the DLNA guidelines, specifies guidelines that define various DLNA Device Profiles. A Device Profile is a collection of DLNA capabilities and features within a DLNA device. A device is compliant with a Device Profile when it conforms to all the guidelines listed for that Device Profile. This second edition cancels and replaces the first edition published in 2013. This edition…
