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…
Electrical insulation systems - Procedures for thermal evaluation - Part 42: Specific requirements f...
IEC TS 61857-42:2025 provides a procedure to evaluate the lifetime of an electrical insulation system (EIS) in a drivetrain unit within road transportation (automotive) applications. Typical applications include motors and generators in hybrid and full electric passenger vehicles, light-duty and heavy-duty commercial vehicles, as well as buses.
In general, the IEC 61857 series is applicable to…
Optical fibre cables - Part 1-214: Generic specification - Basic optical cable test procedures - Env...
IEC 60794-1-214:2025 defines the test procedure used to measure the ability of cable sheath materials to maintain their integrity when exposed to ultraviolet (UV) radiation due to sunlight or fluorescent light.
This first edition cancels and replaces Method F14 of the second edition of IEC 60794‑1‑22 published in 2017. This edition constitutes a technical revision. This edition includes the…
