Virtual power plants - Part 1: Architecture and functional requirements
IEC TS 63189-1:2023 covers the terms and definitions, system composition and control modes of virtual power plant (VPP). It defines the functional requirements for VPPs, including power generation forecasting, load forecasting, generation and consumption scheduling, control and management of energy storage devices and loads, coordinated optimization of distributed energy resources, status…
Electronic displays - Part 3-5: Evaluation of optical performance - Colour capabilities
IEC 62977-3-5:2023 specifies standard evaluation methods for determining the colour capabilities of electronic display modules and systems with respect to colour accuracy, colour gamut volume, and their intersection with a reference colour space. Also included is evaluation with respect to the chromaticity gamut area. These methods apply to emissive and transmissive direct view displays that…
This document defines the general criteria for the development of flight-to-ground umbilical systems used by a space system. These criteria apply to the service arms or equivalent mechanisms, umbilical carriers and plates, couplings, connectors, withdrawal and retract devices, handling mechanisms and control systems for mechanisms, as well as the prevention of accidental cross-connection.

This document specifies requirements for the design, design verification and validation, manufacturing and data control, performance ratings, functional evaluations, handling and storage of tubing-deployed electrical submersible pump (ESP) systems. Additionally, this document provides requirements for assembled ESP system.
This document is applicable to those ESP related components meeting the…
Textiles and textile products — Microplastics from textile sources — Part 2: Qualitative and quantit...
This document establishes a qualitative-quantitative analytical evaluation (i.e. determination) of microplastics to be able to define their:
— particle number;
— morphology (morphological characteristics);
— dimensional distribution;
— the type, chemical origin or nature of polymers and their colour, if present.
This document is applicable to the determination of microplastics (…
Petroleum products — Characterization of marine fuels by viscosity-gravity constant
This document provides best practices on the calculation and use of an informative indicator for the characterization of fossil residual marine fuels not containing FAME as defined in ISO 8217. This document is based on established guidance used by the petroleum industry to characterize petroleum fractions in terms of their paraffinic, naphthenic or aromatic nature, by their viscosity-gravity…
Information technology - Cloud computing - Part 2: Concepts
This document specifies concepts used in the field of cloud computing. These concepts expand upon the cloud computing vocabulary defined in ISO/IEC 22123-1 and provide a foundation for other documents that are associated with cloud computing.
This document also provides detailed descriptions on the application of these concepts in cloud computing.
