IEC 61156-12:2025 specifies cables intended to be used for single balanced pair cabling for office, home and industrial application described in ISO/IEC 11801-1:2017 and ISO/IEC 11801:2017/AMD1 . An example of existing application is 1000BASE-T1, see ISO/IEC TR 11801 9906. The transmission characteristics of these cables are specified up to a frequency of 1,25 GHz and at a temperature of 20 °C.…

IEC 61156-12:2025 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 61156-12:2025 specifies cables intended to be used for single balanced pair cabling for office, home and…

This document provides a methodology for calculating the carbon balance of (a) forest management unit(s) (FMU). This quantification methodology is intended to demonstrate to what extent carbon pools in the FMU represent a net greenhouse gas sink or a net greenhouse gas source. This document provides information that can be used on organizational or aggregated product levels. This calculation…

This document specifies two accelerated corrosion test methods. These methods assess the corrosion resistance of products containing copper in environments where there is a significant influence of chloride ions, mainly as sodium chloride from a marine source or winter road de-icing salt, as well as the influence of corrosion-promoting gases from industrial or traffic air pollution. This document…

This document specifies graphical symbols for diagrams related to industrial components, products and processing. This document constitutes a symbol library, from which users can use the symbols or created symbol examples for use in diagrams (see Tables 1 to 149). General rules and guidance for the preparation and presentation of graphical symbols are given in ISO 14617-1. Application rules for…

This document specifies how to design and operate allocation systems for gas production facilities. It describes the most common types, principles and methods used for the allocation of gas and associated liquids. The objective is to provide an approach to current best practice in the oil and gas industry. It applies to gas and liquid allocations to be performed in production, processing,…

IEC 61987-41: 2025 provides: • a characterization for the integration of process analysers in the Common Data Dictionary (CDD), • generic structures for operating lists of properties (OLOP) and device lists of properties (DLOP) of measuring equipment in conformance with IEC 61987-10, • generic structures for Dynamic Data, e.g. for condition monitoring of process analysers. The generic…

IEC 63270-1:2025 provides guidance on the functional structure model, procedure, method, interface of function blocks. It also offers guidance on data requirements for predictive maintenance of equipment, devices and systems for industrial automation applications. Condition monitoring is not only within the scope of this document but can also be an important input for predictive maintenance.

IEC 60947-7-1:2025 specifies requirements for terminal blocks and test disconnect terminal blocks according to Annex D with screw-type or screw-less-type clamping units primarily intended for industrial or similar use and to be fixed to a support to provide electrical and mechanical connection between copper conductors. It applies to terminal blocks intended to connect round copper conductors,…

Le présent document établit un système de symboles pour les caoutchoucs de base sous la forme sèche ou la forme de latex, basé sur la composition chimique de la chaîne polymérique. Le but du présent document est de normaliser les termes abrégés utilisés dans l’industrie, le commerce et les administrations.
