L'IEC 60670-1:2024 s'applique aux boîtes, enveloppes et parties d'enveloppes (ci-après désignées par les termes "boîtes" et "enveloppes") pour appareillages électriques dont la tension assignée ne dépasse pas 1 000 V en courant alternatif et 1 500 V en courant continu pour installations électriques fixes pour usages domestiques et analogues, en intérieur ou en…

IEC 60331-4:2024 specifies the test apparatus and procedure, and gives the performance requirements, including recommended flame application times and flame temperatures, for power cables of rated voltage higher than 0,6/1,0 kV up to and including 18/30 kV for maintaining circuit integrity when subject to fire and mechanical shock under specified conditions. The test method in this document is…

IEC 61189-2-809:2024 defines the method to be followed for the determination of the X/Y coefficient of thermal expansion of electrical insulating materials by the use of a thermomechanical analyser (TMA). This method is applicable to materials that are solid of the entire range of temperature used and retain sufficient hardness and rigidity over the temperature range so that irreversible…

L’IEC 61189-2-809:2024 définit la méthode à suivre en vue de déterminer le coefficient de dilatation thermique (CTE, coefficient of thermal expansion) X/Y des matériaux isolants électriques à l'aide d'un analyseur thermomécanique (TMA, thermomechanical analyser). La présente méthode est applicable aux matériaux qui sont solides dans toute la plage de températures utilisée, et qui…

IEC 61188-6-3:2024 specifies the requirements for lands and land pattern on circuit boards for the mounting of components with leads by soldering based on the solder joint requirements of IEC 61191-1 and IEC 61191-3. This part of IEC 61188 specifies the requirements for soldering surfaces on circuit boards. This includes lands and land pattern for surface mounted components and also solderable…

La présente partie de l’IEC 61188 spécifie les exigences relatives aux surfaces de brasage sur les cartes imprimées. Sont incluses les…

This document describes the series of privacy, security, and safety standards to support the HES Gateway and attached devices. The purpose is to specify methods for protecting home and building systems from both internal and external threats, intrusions, or unintended observation of data and unsafe conditions that could result from network functions. Part 3 defines a set of basic and advanced…

This document describes best practices for use case projects in terms of projects, templates and plans, with the objective to improve the consistency of content across different use case projects and enable sharing of knowledge between projects. A long-term goal is to foster interoperability between tools supporting the collection and maintenance of use cases. This document is intended for…

This document specifies a method for determining the pour point of petroleum products by means of automatic equipment for detecting movement of the test specimen using a linear cooling technique. A separate procedure suitable for the determination of the lower pour point of fuel oils, heavy lubricant base stock, and products containing residual fuel components is also described. The procedure…

This standard provides a comprehensive set of procedures for verifying the correct implementation of each capability claimed on a BACnet PICS including: (a) support of each claimed BACnet service, either as an initiator, executor, or both, (b) support of each claimed BACnet object-type, including both required properties and each claimed optional property, (c) support of the BACnet network layer…
