L'IEC 60809:2021 est applicable aux sources lumineuses électriques (voir Note 1) destinées à être utilisées dans les applications automobiles, par exemple dans les dispositifs d'éclairage de la route et/ou les appareils de signalisation pour véhicules routiers. Il s'applique en particulier aux sources lumineuses répertoriées dans la Résolution R.E.5 de l'ONU et aux sources…

IEC 61753-111-08:2021 contains the minimum tests, test severities and measurement requirements which a sealed fibre optic closure need to meet in order to be categorised as meeting the IEC standard for category G - Ground, as defined in Table A.14 of IEC 61753-1:2018. Free breathing closures are not covered in this document. This first edition cancels and replaces IEC 61753-111-8 published in…

IEC 61753-111-08: 2021 contient les essais, les sévérités d’essai et les exigences de mesure minimaux auxquels un boîtier fibronique scellé est tenu de satisfaire afin d’être classé comme conforme aux exigences de la norme IEC pour la catégorie G – au niveau du sol, telle qu’elle est définie dans le Tableau A.14 de l’IEC 61753‑1:2018. Les boîtiers à ventilation libre ne sont pas couverts par le…

IEC 60794-3-70:2021 covers outdoor optical fibre cables intended for rugged terrestrial rapid/multiple deployment. These cables, with enhanced mechanical, environmental and ingress performance can be used wherever a rapid or multiple deployment is relevant (e.g. mobile broadcast units, emergency rescue services, tactical ground-forces, outdoor motion-robotics, mining machinery, temporary repair…

IEC 60794-3-70:2021 est une spécification de famille qui couvre les câbles à fibres optiques extérieurs destinés à un déploiement rapide/multiple terrestre renforcé. Ces câbles, dont les performances mécaniques, environnementales et d’infiltration sont améliorées, peuvent être utilisés partout où un déploiement rapide ou multiple est applicable (par exemple, dans des unités mobiles de diffusion,…

This document provides a calculation method for bevel and hypoid gears regarding scuffing based on experimental and theoretical investigation[7]. This calculation method is a flash temperature method. The formulae in this document are intended to establish uniformly acceptable methods for calculating scuffing resistance of straight, helical (skew), spiral bevel, Zerol and hypoid gears made of…

Variable message signs (VMSs) are installed in areas where traffic managers identify a frequent need to convey information to the travelling public, such as upstream from interchanges to alert the public to downstream congestion in time for them to alter their routes. This allows traffic managers to improve the efficiency, safety, and quality of traveller journeys. In order to manage the…

This version of the specification models various details of the following objects of the media library for monitoring. Library Drives Changer Devices Slots IO Slots SCSI Interfaces and SCSI and FC Target Ports Physical Tapes Physical Package Magazines In general, a CIM client can monitor the health and status of the above objects as well as get alert, status change and lifecycle CIM indications…

Storage Management Technical Specification, Part 2 Common Architecture, 1.8.0 Rev 4 defines the core architecture and protocols in SMI-S. The components of SMI-S architecture include: Transport - communicating management information between constituents of the management system Health and fault management - detecting failures through monitoring the state of storage components General information…

Storage Management Technical Specification, Part 3 Common Profiles, 1.8.0 Rev 4 defines profiles that are supported by profiles defined in the other parts of this standard. The first few clauses provide background material that helps explain the purpose and profiles. Common port profiles are grouped together since they serve as transport-specific variations of a common model. The port profiles…
