L'IEC 62920:2017+A1:2021 spécifie les exigences de compatibilité électromagnétique (CEM) pour les équipements de conversion de puissance (PCE) en courant continu et en courant alternatif utilisés dans les systèmes de production photovoltaïque (PV). Le PCE couvert par le présent document peut être couplé au réseau ou autonome. Il peut être alimenté par un ou plusieurs modules photovoltaïques…
Surface chemical analysis — Sample handling, preparation and mounting — Part 3: Biomaterials
This document gives guidance on methods of handling, mounting and surface treatment for a biomaterial specimen prior to surface chemical analysis. It is intended for the analyst as an aid in understanding the specialized specimen-handling conditions required for analyses by the following techniques:
— X-ray photoelectron spectroscopy (XPS or ESCA);
— secondary ion mass spectrometry (SIMS…
Health informatics — Interoperability and integration reference architecture — Model and framework
This document enables the advancement of interoperability from the data/information exchange paradigm to knowledge sharing at decreasing level of abstraction, starting at IT concept level (semantic coordination) through business domain concept level (agreed service function level cooperation), domain level (cross-domain cooperation) up to individual context (skills-based end-user collaboration).…
