This part of IEC 60839 specifies the minimum functionality, performance requirements and test methods for electronic access control systems and components used for physical access (entry and exit) in and around buildings and protected areas. It does not include requirements for access point actuators and sensors. This standard is not intended to cover requirements for off premise transmission…

IEC 62271-204:2022 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 62271-204:2022 applies to rigid HV gas‑insulated transmission lines (GIL) in which the insulation is obtained,…

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 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changes with respect to the previous edition: a) IEC 60953-2:1990 has been used as the basis to develop IEC 60953-0; b) Outdated measuring techniques have been updated and the corresponding reduction of the expected test result measuring uncertainty indicated; c) Guarantee of power…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 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 61169-71:2022, which is a sectional specification (SS), provides information and rules for the preparation of detail specifications (DS) for RF coaxial connector, typically for use in 50 Ω radio communication systems, type NEX10® . This document describes mating face dimensions for general purpose connectors (grade 2), dimensional details of standard test connectors (grade 1), gauging…

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 establishes requirements for reciprocating internal combustion engines to minimize the risk of fire caused by the engine, its components and the auxiliaries fitted to it. Where necessary, special requirements can be given for particular engine applications. This document applies to reciprocating internal combustion engines for land and marine use, excluding engines used in an…

This document specifies the characteristics of solid, liquid or gas sources of gamma emitting radionuclides used as reference measurement standards for the calibration of gamma-ray spectrometers. These reference measurement standards are traceable to national measurement standards. This document does not describe the procedures involved in the use of these reference measurement standards for the…
