IEC 62541-15:2025 describes a safety communication layer (services and a protocol) for the exchange of SafetyData using IEC 62541 mechanisms. It identifies the principles for functional safety communications defined in IEC 61784‑3 that are relevant for this safety communication layer. This safety communication layer is intended for implementation in safety devices only. NOTE 1 This document…

This document specifies physical and performance requirements, test methods and marking requirements for industrial protective helmets. This document describes the requirements for two helmet types. Type I — intended to protect the upper part of wearer’s head against impacts that may occur in an industrial setting, such as a falling object. Type II — intended to protect the head against impacts…

This document specifies the design requirements for architectural supports, in terms of their shape and dimensions, material, strength, etc. This document covers architectural supports of topside and living-quarter regions for fixed or floating offshore oil and gas platforms including lower carbon energy.

Le présent document spécifie les exigences de conception pour les supports architecturaux, en matière de forme et de dimensions, de matériaux, de résistance, etc. Le présent document couvre les supports architecturaux des zones Top Sides et des quartiers de vie pour les plateformes pétrolières et gazières en mer fixes ou flottantes, y compris les énergies à faible teneur en carbone.

The commented version provides you with a quick and easy way to compare all the changes between IEC 61039:2025 edition 3.0 and the previous IEC 61039:2008 edition 2.0. Furthermore, comments from IEC TC 10 experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content…

IEC 61039:2025 establishes the detailed classification of the N family (insulating liquids) that belongs to class L (lubricants, industrial oils and related products) in accordance with ISO 8681 and ISO 6743-99, affecting product categories that include products derived from petroleum processing, synthetic chemical products and synthetic and natural esters.

Le présent document spécifie une méthode pour déterminer la teneur totale des cyclosiloxanes suivants dans les produits chimiques pour l’industrie du tannage du cuir: —     l’octaméthylcyclotétrasiloxane (D4); —     le décaméthylcyclopentasiloxane (D5); —     le dodécaméthylcyclohexasiloxane (D6). Cette méthode nécessite de recourir à la chromatographie en phase gazeuse (CPG) couplée à un…

This document specifies a method for determining the total content of the following cyclosiloxanes in chemicals for the leather tanning industry: —     octamethylcyclotetrasiloxane (D4); —     decamethylcyclopentasiloxane (D5); —     dodecamethylcyclohexasiloxane (D6); This method requires the use of gas chromatography (GC) equipped with a single quadrupole mass spectrometer (MS) to identify and…

Le présent document contient les dispositions relatives à la conception géotechnique qui s'appliquent à une vaste gamme de structures en mer, plutôt qu'à un type particulier de structure. Le présent document décrit les méthodes développées principalement pour la conception des fondations superficielles avec un rapport entre longueur enfouie (L) et diamètre (D) L/D < 0,5, des…

This document contains provisions for geotechnical engineering design that are applicable to a broad range of offshore structures, rather than to a particular structure type. This document outlines methods developed for the design of shallow foundations with an embedded length (L) to diameter (D) ratio L/D < 0,5, intermediate foundations, which typically have 0,5 ≤ L/D ≤ 10 (see Clause 7), and…
