Communication networks and systems for power utility automation - Part 90-20: Use cases of redundanc...
IEC TR 61850-90-20:2025, which is a technical report, describes use cases of redundancy in systems.
This document considers use cases of duplication of function and devices and covers redundancy of information flow at message level. Functional safety is out of scope of this document. To keep focus on details relevant for this document, some figures and drawings do not show electrical wiring,…
Environmental testing - Part 2-78: Tests - Test Cab: Damp heat, steady state
IEC 60068-2-78:2025 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.
IEC 60068-2-78:2025 establishes a test method for determining the ability of components or equipment to withstand…
This document specifies a method using energy-dispersive X-ray fluorescence spectrometry for the determination of the sulfur content of petroleum products, such as naphthas, unleaded motor gasolines, middle distillates, residual fuel oils, base lubricating oils and components. The method is applicable to products with sulfur content in the range of a mass fraction of 0,03 % to a mass fraction of…

L'ISO 8754:2003 spécifie une méthode d'essai qui a pour but de déterminer la teneur en soufre des produits pétroliers tels que naphtas, essences sans plomb, distillats moyens, combustibles résiduels, huiles de base et constituants. La méthode est applicable aux produits dont la teneur en soufre est comprise entre 0,03 % (en masse) et 5 % (en masse).
Information technology — Coding of audio-visual objects — Part 24: Audio and systems interaction
This document describes the desired joint behaviour of MPEG-4 Systems (MPEG-4 File Format) and MPEG-4 Audio codecs. It is desired that MPEG-4 Audio encoders and decoders permit finite length signals to be encoded to a file (particularly MPEG-4 files) and decoded again to obtain the identical signal, subject to codec distortions. This enables the use of audio in systems implementations (…
