IEC TS 62861:2017(E) This Technical Specification provides guidelines for establishing confidence in product reliability using principal component testing for LED light sources and LED luminaires for general lighting. It includes methods and criteria using initial qualification tests and accelerated stress tests of the principal components. The performance of any principal component will…

L’IEC 60749-4:2017 décrit un essai de contrainte de température et d’humidité fortement accéléré (HAST, highly accelerated temperature and humidity stress test) qui est réalisé dans le but d’évaluer la fiabilité des dispositifs à semiconducteurs sous boîtier non hermétique dans les environnements humides. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’…

Le présent document fournit une présentation générale du fonctionnement d'un système de tomographie informatisée (TI) et de l'interprétation des résultats afin de donner à l'utilisateur des informations techniques pour sélectionner les paramètres adaptés. Il est applicable à l'imagerie industrielle (c'est-à-dire aux applications non médicales) et donne un ensemble…

ISO 22201-1:2017 is applicable to the product family of passenger and goods/passenger lifts used in residential buildings, offices, hospitals, hotels, industrial plants, etc. This document covers those aspects that it is necessary to address when programmable electronic systems are used to carry out electric safety functions for lifts (PESSRAL). This document is applicable for lift safety…

L'IEC 61851-1:2017 s'applique au système d’alimentation pour VE destiné à charger les véhicules routiers électriques, avec une tension assignée d’alimentation jusqu'à 1 000 V en courant alternatif ou 1 500 V en courant continu, et une tension de sortie assignée jusqu'à 1 000 V en courant alternatif ou 1 500 V en courant continu.

ISO 22412:2017 specifies the application of dynamic light scattering (DLS) to the measurement of average hydrodynamic particle size and the measurement of the size distribution of mainly submicrometre-sized particles, emulsions or fine bubbles dispersed in liquids. DLS is also referred to as "quasi-elastic light scattering (QELS)" and "photon correlation spectroscopy (PCS),"…

1.1 This part of the IEC 61508 series a) is intended to be used only after a thorough understanding of IEC 61508-1, which provides the overall framework for the achievement of functional safety; b) applies to any safety-related system, as defined by IEC 61508-1, that contains at least one electrical, electronic or programmable electronic element; c) applies to all elements within an E/E/PE safety…

1.1 This International Standard covers those aspects to be considered when electrical/electronic/programmable electronic (E/E/PE) systems are used to carry out safety functions. A major objective of this standard is to facilitate the development of product and application sector international standards by the technical committees responsible for the product or application sector. This will allow…

1.1 This part of the IEC 61508 series a) is intended to be utilized only after a thorough understanding of IEC 61508-1 and IEC 61508-2; b) applies to any software forming part of a safety-related system or used to develop a safety-related system within the scope of IEC 61508-1 and IEC 61508-2. Such software is termed safety-related software (including operating systems, system software, software…

This part of IEC 61511 gives requirements for the specification, design, installation, operation and maintenance of a safety instrumented system (SIS), so that it can be confidently entrusted to achieve or maintain a safe state of the process. IEC 61511-1 has been developed as a process sector implementation of IEC 61508:2010. In particular, IEC 61511-1: a) specifies the requirements for…
