IEC 60953-0:2022 constitutes a technical revision.This edition includes the following significant technical changes with respect to the previous edition: a) IEC 60953-2:1990 has been used as the basis to develop IEC 60953-0; b) Outdated measuring techniques have been updated and the corresponding reduction of the expected test result measuring uncertainty indicated; c) Guarantee of power…

IEC 63173-2:2022 the scope of secure communication between ship and shore (SECOM) includes interfaces (APIs) for data exchange (information services), information security measures to enable secure communication and interfaces for service discoverability. SECOM provides technical interoperability, where the same service interface is used for exchanging the information regardless of its…

IEC 62271-203:2022 specifies requirements for gas-insulated metal-enclosed switchgear in which the insulation is obtained, at least partly, by an insulating gas or gas mixture other than air at atmospheric pressure, for alternating current of rated voltages above 52 kV, for indoor and outdoor installation, and for service frequencies up to and including 60 Hz. This third edition cancels and…

IEC 61970-401:2022 describes how IEC 61970-450 (all parts), IEC 61970-600 (all parts) profile specifications are structured and created. Profile specifications describe a subset of the Canonical CIM dedicated to a specific data exchange. The Canonical CIM is described in IEC 61970 300 (all parts) as well as in IEC 61968-11. Rules for creation or extension of Canonical CIM are outside the scope…

IEC 62271-203:2022 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 62271-203:2022 edition 3.0 and the previous IEC 62271-203:2011 edition 2.0. Furthermore, comments from IEC SC 17C experts are provided to explain the reasons of the most relevant changes, or to clarify any part of…

IEC TR 63363-1:2022(E) is to present the "state of the art" with respect to general guidance on the steady-state performance demands of VSC HVDC transmission systems. It concerns the steady-state performance of two-terminal VSC HVDC transmission systems utilizing converters with power flow capability in both directions. Different configurations of a VSC HVDC transmission system are…

IEC 61131-9:2022 specifies a single-drop digital communication interface technology for small sensors and actuators SDCI (commonly known as IO-Link™ ), which extends the traditional digital input and digital output interfaces as defined in IEC 61131-2 towards a point-to-point communication link for the exchange of complex data in both directions. This techno¬logy also enables the transfer of…

support equipment (GSE) with respect to a risk of fire, electric shock, and explosion hazards associated with the battery powered electrical system. 1.2 These requirements also cover these electrical systems when they are used to convert fueled GSE to battery powered GSE. 1.3 In accordance with 1.1, the minimum GSE electrical system consists of the battery and integral battery management…

This document provides nomenclature for general modes of gear tooth wear and failure. It classifies, identifies, and describes the most common types of failure and provides information that, in many cases, enables the user to identify failure modes and evaluate the degree or change from original condition. This document is based on experience with steel gears; however, many of the failure modes…

This document defines terminology related to autonomous ship systems, which includes ships that can be classified as a “Maritime Autonomous Surface Ship” (MASS) according to the preliminary definitions from the International Maritime Organization (IMO). Autonomous ship system can also be applied to similar ship types for use on inland waterways.
