EN 60297-3-109:2016

Mechanical structures for electrical and electronic equipment - Dimensions of mechanical structures of the 482,6 mm (19 in) series - Part 3-109: Dimensions of chassis for embedded computing devices

IEC 60297-3-109:2015 specifies dimensions and physical properties of chassis and associated printed boards in order to provide mechanical and environmental integrity for embedded computing devices. They are used in various applications such as machine control, medical, transportation, aerospace and telecommunication, typically based on single board computers. For the easy definition of the suitable chassis and associated single board dimensions, this standard is based on a structural grid of 44,45 mm (1,75 in). Key words: Dimensions, Mechanical Structures, Chassis, Embedded Computing Devices

Structures mécaniques pour équipements électriques et électroniques -Dimensions des structures mécaniques de la série 482,6 mm (19 pouces) – Partie 3-109: Dimensions des châssis pour dispositifs informatiques intégrés

L'IEC 60297-3-109:2015 spécifie les dimensions et les propriétés physiques des châssis et des cartes imprimées associées, afin de garantir l'intégrité mécanique et environnementale des dispositifs informatiques intégrés. Ces derniers sont utilisés dans de nombreuses applications, notamment pour commander des machines dans les environnements de la santé, des transports, de l'aérospatial et des communications. Il s'agit généralement d'ordinateurs monocartes. Pour faciliter la définition des dimensions adaptées des châssis et cartes imprimées associées, la présente norme se base sur une grille structurelle de 44,45 mm (1,75 pouce). Mots-clés: Dimensions, Structures mécaniques, Châssis, Dispositifs informatiques intégrés

Mehanske konstrukcije za elektronsko opremo - Mere mehanskih konstrukcij serije 482,6 mm (19 palcev) - 3-109. del: Mere ohišij za vgrajeno računalniško opremo

Ta del standarda IEC 60297 določa mere in fizikalne lastnosti ohišij in z njimi povezanih tiskanih plošč, da se zagotovi mehanska in okoljska neoporečnost za vgrajene računalniške naprave. Uporabljajo se za različne namene, npr. nadzor strojev, medicinske namene, prevoz, vesoljske namene in telekomunikacije, kjer se običajno uporabljajo računalniki z eno matično ploščo.
Za enostavno opredelitev ustreznega ohišja in mer z njim povezane matične plošče ta standard temelji na strukturni mreži 44,45 mm (1,75 palca).

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation.
