IEC 62899-402-3:2021(E) specifies the optical measurement method for acquiring two-dimensional images of voids and obtaining the void-related attributes in the dried or cured printed patterns which are part of the electronic products in the field of printed electronics. The measurable voids using this document are limited to those that are distinguishable by the optical image measurement. NOTE …

IEC 60809:2021 is applicable to electric light sources for use in automotive applications, for example in road illumination devices and/or light signalling devices for road vehicles. It is especially applicable to light sources listed in UN Resolution R.E.5 and light sources subject to other legislations. This fourth edition cancels and replaces the third edition published in 2014, Amendment 1:…

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…

IEC 60286-1:2017+A1:2021 applies to the tape packaging of components with axial leads for use in electronic equipment. In general, the tape is applied to the component leads. It covers requirements for taping techniques used with equipment for the preforming of leads, automatic handling, insertion and other operations, and includes only those dimensions which are essential to the taping of…
