This document specifies the information to be recorded in a metadata registry in the form of a conceptual data model: —    Clause 5 specifies the approach used to model a metadata registry; —    Clause 6 specifies the Core Model of the registry, including basic types and classes to be reused in extending the model. The core model defines a generic “registry item”, from which any type of item that…

IEC 62351-5:2023 defines the application profile (A-profile) secure communication mechanism specifying messages, procedures and algorithms for securing the operation of all protocols based on or derived from IEC 60870-5, Telecontrol Equipment and Systems – Transmission Protocols. For the measures described in this document to take effect, they must be accepted and referenced by the…

IEC TS 62736:2023 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 TS 62736:2023 specifies requirements and methods for periodic testing of the quality of diagnostic medical…

IEC TS 62736:2023 specifies requirements and methods for periodic testing of the quality of diagnostic medical ultrasound systems using reflection-mode (pulse-echo) imaging. Image measurement and interpretation workstations are included. This document includes minimum sets of such tests intended for frequent users of medical ultrasound systems, for quality assurance professionals in their…

This document specifies two laboratory methods for testing certain essential strength characteristics of disc wheels intended for road use on commercial vehicles, buses, trailers, and multipurpose passenger vehicles, as defined in ISO 3833. The test methods are: —    dynamic cornering fatigue test and —    dynamic radial fatigue test.

Classes A1a and B1a porcelain (as defined in ISO 13006) are now manufactured in much larger formats than previously available and are increasingly being used as an external cladding material for buildings. Classes A1b, A11a, and AIIb extruded ceramics (as defined in ISO 13006) are not covered by the scope of this document. These materials, when specifically developed for external façade…

IEC 62146-2:2023 is applicable to TRV capacitors used on high-voltage alternating current circuit-breakers with rated voltages above 100 kV with 50 Hz or 60 Hz. TRV capacitors are installed phase to earth, either in parallel to the bushing on dead tank circuit-breakers, or immersed inside the circuit-breaker, or freestanding close to the circuit-breaker. Their function is to limit the transient…

This document specifies a family of scene-referred extended colour gamut RGB colour image encodings designated as reference input medium metric RGB (RIMM RGB). Digital images encoded using RIMM RGB can be manipulated, stored, transmitted, displayed or printed by digital still picture imaging systems. Three precision levels are defined using 8-, 12- and 16-bits/channel. An extended luminance…
