This document defines a number of subsets of the syntax specified in ISO/IEC 21122-1 as profiles. It also defines lower bounds on the throughput in the decoded domain via levels and the encoded domain via sublevels that a conforming decoder implementation shall support. Furthermore, it defines a buffer model to ensure interoperability between implementations in the presence of a latency…

This document defines transport and container formats for JPEG XS codestreams as specified in ISO/IEC 21122-1. It defines file formats for working with still image and motion image sequence files on computer platforms and gives guidance on how to embed the codestream in transport streams, allowing internet-based communication. This document uses already existing specifications for file formats…

This document defines the syntax and an accompanying decompression process that is capable to represent continuous-tone grey-scale, or continuous-tone colour digital images without visual loss at moderate compression rates. Typical compression rates are between 2:1 and 6:1 but can also be higher depending on the nature of the image. In particular, the syntax and the decoding process specified in…

This document establishes a systematic description of the concepts in the field of biometrics pertaining to recognition of human beings. This document also reconciles variant terms in use in pre-existing International Standards on biometrics against the preferred terms, thereby clarifying the use of terms in this field. This document does not cover concepts (represented by terms) from information…

Le présent document établit une description systématique des concepts du domaine de la biométrie, en rapport avec la reconnaissance des êtres humains. Il fait le rapprochement entre les variantes de termes utilisées dans des Normes internationales préexistantes sur la biométrie et les termes privilégiés, permettant ainsi de clarifier l'usage des termes dans ce domaine. Le présent document ne…

IEC PAS 63422:2022(E) Book 20 defines a smart interface between an indoor LED luminaire and a sensing/communication module. The module connects to the LED driver and control system, and typically can provide sensory inputs or enable communication between network components. Modules can be installed and replaced in the field. Book 1 defines the common concepts that underlie the Zhaga interface…

IEC TS 62804-2:2022 defines apparatus and procedures to test and evaluate the durability of photovoltaic (PV) modules to power loss by the effects of high voltage stress in a damp heat environment, referred to as potential-induced degradation (PID). This document defines a test method that compares the coulomb transfer between the active cell circuit and ground through the module packaging under…

This document defines terms used in the hose industry. Recommended terminology for electrical conductivity and resistance of rubber and plastics hoses and hose assemblies can be found in ISO 8031:2020, Annex A.

Le présent document définit les termes utilisés dans l’industrie des tuyaux. La terminologie recommandée pour la conductivité électrique et la résistance électrique des tuyaux et flexibles en caoutchouc et en plastique se trouvent dans l’ISO 8031:2020, Annexe A.

Le présent document spécifie une méthode de séchage à l’étuve pour la détermination de la teneur en matières sèches dans le papier, le carton, la pâte et les nanomatériaux cellulosiques sous forme solide, tous pouvant être produits à partir de matériaux vierges et/ou recyclés. Elle est aussi applicable pour la détermination de la teneur en matières sèches du papier et du carton à recycler. La…
