IEC 63044-6:2021 specifies the requirements for planning and installation of HBES/BACS and the supporting infrastructure. Radio frequency (RF) HBES/BACS are also considered. Safety requirements are covered by IEC 60364 (all parts). Information and communication technology (ICT) and broadcasting and communication technology (BCT) network installations are typically interfaced with HBES/BACS.…

IEC 60794-1-31:2021 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 60794-1-31:2021 which is a generic specification, covers optical fibre ribbons. Requirements which are…

IEC 60794-1-31:2021 which is a generic specification, covers optical fibre ribbons. Requirements which are described in this part apply to optical fibre ribbon cables for use with telecommunication equipment and devices employing similar techniques, in particular optical fibre cables in IEC 60794-2 for indoor use, in IEC 60794-3 for outdoor use, in IEC 60794-4 for self-supporting overhead use, in…

IEC 60794-1-31:2021 qui est une spécification générique, s’applique aux rubans de fibres optiques. Les exigences qui sont décrites dans la présente partie s’appliquent aux câbles à rubans de fibres optiques destinés à être utilisés dans les équipements de télécommunications et les dispositifs utilisant des techniques analogues, en particulier les câbles à fibres optiques de l’IEC 60794-2 pour une…

This document provides a description of methods by which the coating thickness and chemical composition of "core-shell" nanoparticles (including some variant and non-ideal morphologies) can be determined using electron spectroscopy techniques. It identifies the assumptions, challenges, and uncertainties associated with each method. It also describes protocols and issues for the general…

IEC TS 63236-1:2021(E) applies to DC appliance couplers for class I equipment with two active contacts plus an earthing contact, a rated power of 2,6 kW and a rated voltage range from 294 V to 400 V DC. They are intended to power DC information and communication technology equipment only, as specified in IEC 62368‑1.

IEC TS 63236-3:2021(E) sets the additional requirements for appliance inlets used for information and communication technology (ICT) equipment installed in data centres and telecom central offices and which are suitable for both alternating current and direct current. This Part 3 is to be used in conjunction with IEC TS 63236-1:2021.

This document describes a laboratory test method, using an IGT1-type or a prüfbau2-type printability tester, for the preparation of specimens to evaluate the absorption rate of an ink on a substrate in offset lithography by setting-off the printed surface to an unprinted surface. This method describes testing with an amount of ink simulating either single colour or multi-colour printing. The…

IEC TS 63236-2:2021(E) applies to DC appliance couplers for class I equipment with two active contacts plus an earthing contact, a rated power of 5,2 kW and a rated voltage range from 294 V to 400 V DC. They are intended to power DC information and communication technology equipment only, as specified in IEC 62368-1. This Part 2 is to be used in conjunction with IEC TS 63236-1:2021.

This document specifies MAC algorithms that use a secret key and a hash-function (or its round-function or sponge function) to calculate an m-bit MAC. These mechanisms can be used as data integrity mechanisms to verify that data has not been altered in an unauthorized manner. NOTE       A general framework for the provision of integrity services is specified in ISO/IEC 10181‑6.
