Information technology — Image processing and interchange (IPI) functional specification — Part 5: B...
This document establishes the specification of the Basic image interchange format (BIIF). This document provides a foundation for interoperability in the interchange of imagery and imagery-related data among applications. It also provides a detailed description of the overall structure of the format, as well as specification of the valid data and format for all fields defined with BIIF. Annex C…
Information technology — Generic coding of moving pictures and associated audio information — Part 1...
This document specifies the system layer of the coding. It was developed principally to support the combination of the video and audio coding methods defined in Parts 2 and 3 of ISO/IEC 13818. The system layer supports six basic functions:
1) the synchronization of multiple compressed streams on decoding;
2) the interleaving of multiple compressed streams into a single stream;
3) the…

OPC unified architecture - Part 18: Role-Based Security
IEC 62541-18: 2025 defines an Information Model. The Information Model describes the basic infrastructure to model role-based security.
NOTE In the previous version, Role-Based Security was in IEC 62541-5:2020, Annex F.
Architecture unifiée OPC - Partie 18: Sécurité fondée sur les rôles
IEC 62541-18: 2025 définit un modèle d'information. Le modèle d'information décrit l'infrastructure de base pour modéliser la sécurité fondée sur les rôles.
NOTE Dans la version précédente, la sécurité fondée sur les rôles figurait dans l'IEC 62541-5:2020, Annexe F.
Safe management and operation of electrical installations
IEC TS 63527:2025 is applicable to the safe management and operation of and work activity on, with, or near electrical installations operating at voltage levels from and including extra-low voltage up to and including high voltage.
This latter term includes those levels commonly referred to as medium and extra-high voltage.
These electrical installations are designed for the generation,…
Geographic information — Land Administration Domain Model (LADM) — Part 5: Spatial plan information
This document:
— specifies a reference land administration domain model (LADM) covering basic information-related components of spatial plan information on land/water and elements below/on/above the surface of the Earth with 2D/3D/4D (3D + time) geometric representation;
— provides an abstract, conceptual model with packages related to:
— plan unit, i.e. the smallest homogenous area/…
