This document specifies the Image File Format, an interoperable storage format for a single image, a collection of images, and sequences of images. The format defined in this document is built on tools defined in ISO/IEC 14496-12 and enables the interchange, editing, and display of images, as well as the carriage of metadata associated with those images. The Image File Format defines structures…

This document provides guidance on how four complementary international standards can be used in combination by developers of health ICT systems and infrastructures. These standards, three published by CEN and ISO and one by HL7, are —     ISO 13940:2015, —     ISO 13606-1:2019, —     ISO 13606-3:2019, and —     HL7 Fast Health Interoperability Resources (FHIR) Release 4. This document defines…

This document specifies a method for the determination in a closed conduit of the volume rate of flow of a regular flow a)       of a fluid of substantially constant density or corresponding to a Mach number not exceeding 0,25, b)       with substantially uniform stagnation temperature across the measuring cross-section, c)        running full in the conduit, and d)       under steady flow…

This document specifies field procedures to be adopted when determining and evaluating the precision (repeatability) of rotating lasers, the uncertainty of measurement results obtained by geodetic instruments and their ancillary equipment, particularly when used in building and surveying measurements for levelling tasks. Primarily, these tests are intended to be field verifications of the…

This document specifies the minimum image quality values (using IQIs) to ensure a uniform radiographic image quality. This document specifies the minimum IQI values for the two testing classes, A and B, of radiographic techniques as specified in ISO 5579. This document is applicable to the two types of image quality indicators as detailed in ISO 19232-1 for wire-type IQIs and ISO 19232-2 for step…

Le présent document spécifie les indices de qualité d’image (en utilisant les IQI) minimaux permettant d’assurer une qualité d'image radiographique uniforme. Le présent document spécifie les indices IQI minimaux pour les deux classes d’essai, A et B, de techniques radiographiques spécifiées dans l’ISO 5579. Le présent document est applicable aux deux types d’indicateurs de qualité d’image…

This document specifies categorial structures within the subject field of acupuncture needling (specialized for using filiform needles) by defining a set of domain constraints. This document describes a concept system detailing domain constraints of sanctioned characteristics, each composed of a semantic link and an applicable characterizing category.

Le présent document spécifie des méthodes de laboratoire qui ont pour but de reproduire les effets des réactions se produisant naturellement, telles que l’oxydation ou l’hydrolyse causées par l’humidité pour les matériaux polymères alvéolaires souples et rigides.

This document specifies the safety requirements of hydrogen gas generation appliances or systems that use electrochemical reactions to electrolyse water to produce hydrogen, herein referred to as hydrogen generators.

IEC TR 62368-2:2025 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 TR 62368-2:2025 identifies the purpose and applicability of IEC 62368-1:2023 and the exclusions from the scope…
