Communication networks and systems for power utility automation - Part 2: Glossary
IEC TS 61850-2:2019 (E) contains the glossary of specific terms and definitions used in the context of Substation Automation Systems which are standardized in the various parts of the IEC 61850 series.
This second edition cancels and replaces the first edition, published in 2003. This edition constitutes a technical revision. This edition includes the following significant technical changes with…
Liquid crystal display devices - Part 40-1: Mechanical testing of display cover glass for mobile dev...
IEC 61747-40-1:2019 provides mechanical performance testing guidelines for cover glass used in electronic flat panel displays in mobile devices. This document focuses on key mechanical testing performance parameters and covers mainly strength and damage resistance attributes. The test methods focus on the cover glass level testing only. This edition includes the following significant technical…
Organic light emitting diode (OLED) displays - Part 6-5: Measuring methods of dynamic range properti...
IEC TS 62341-6-5:2019 (E) specifies the standard measurement conditions and dynamic range properties for OLED display panels and modules. More precisely, this document focuses on the specific aspects of the dynamic range properties.
Explosive atmospheres - Part 42: Electrical safety devices for the control of potential ignition sou...
IEC TS 60079-42:2019 provides guidance for equipment manufacturers where electrical safety devices are used to reduce the likelihood of potential ignition sources becoming effective in Ex Equipment located in Explosive Atmospheres. Electrical safety devices perform a safety function to control potential ignition sources from both, electrical or non-electrical Ex Equipment in explosive atmospheres…
Atmosphères explosive - Partie 42: Dispositifs électriques de sécurité pour la commande des sources ...
IEC TS 60079-41:2019 fournit des recommandations pour les constructeurs d’appareils lorsque des dispositifs électriques de sécurité sont utilisés pour réduire la probabilité que les sources potentielles d’inflammation deviennent effectives dans les appareils Ex situés en atmosphères explosives. Les dispositifs électriques de sécurité exécutent une fonction de sécurité pour contrôler les sources…
Extended thermal cycling of PV modules - Test procedure
IEC 62892:2019 defines a test sequence that extends the thermal cycling test of IEC 61215-2. It is intended to differentiate PV modules with improved durability to thermal cycling and evaluate modules for deployment in locations most susceptible to thermal cycling type stress. This document is based on the ability for 95 % of the modules represented by the samples submitted for this test to pass…
