Mechanical structures for electronic equipment - Tests for IEC 60917 and IEC 60297 - Part 5: Seismic tests for chassis, subracks and plug-in units

IEC 61587-5:2013 specifies seismic test requirements for chassis, subracks, and plug-in units as defined in the IEC 60297 and IEC 60917 series. It applies in whole or in part, only to the mechanical structures of chassis, subracks, and plug-in units for electronic equipment, according to the IEC 60297 and IEC 60917 series, and does not apply to electronic components, equipment or systems within the mechanical structures. The object of this standard is to establish a level of physical integrity of chassis, subracks, and plug-in units according to IEC 60297 and IEC 60917 series that may provide a level of survivability that will preserve functionality during and after a seismic occurrence. It is intended to provide the user with a high level of confidence in the selection of an equipment practice to meet such needs. Since IEC 60297 and IEC 60917 series chassis, subracks, and plug-in units come in many sizes, weights and mechanical complexities, it is not possible to define a single minimum seismic test requirement for all weight categories. Therefore, overall mass categories are defined in this standard. However, the mass distribution inside a chassis and subrack is considered 'application-specific' and herein defined as 'intended use'. Key words: chassis, subracks, plug-in units, seismic tests

Structures mécaniques pour équipement électronique - Essais pour la CEI 60917 et la CEI 60297 - Partie 5: Essais sismiques pour châssis, bacs et unités enfichables

L'IEC 61587-5:2013 spécifie les exigences d'essai sismique pour les châssis, les bacs et les unités enfichables tels que définis dans les séries CEI 60297 et CEI 60917. Elle s'applique, en tout ou en partie, seulement aux structures mécaniques des châssis, des bacs et des unités enfichables pour les équipements électroniques, conformément aux séries CEI 60297 et CEI 60917, et ne s'applique pas aux équipements ou systèmes électroniques, aux équipements ou aux systèmes qui se trouvent à l'intérieur de ces structures mécaniques. L'objet de la présente norme est d'établir un niveau d'intégrité physique des châssis, des bacs et des unités enfichables, conformément aux séries CEI 60297 et CEI 60917, qui peut fournir un niveau de pérennité qui protégera la fonctionnalité pendant et après une occurrence sismique. L'objectif est d'aider l'utilisateur à mieux choisir une structure appropriée pour satisfaire à ses besoins spécifiques. Les châssis, les bacs et les unités enfichables décrits dans les CEI 60297 et CEI 60917 ont diverses tailles, poids et complexités mécaniques; aussi, on ne peut pas définir une seule exigence d'essai sismique minimum pour toutes les catégories de poids. Des catégories de masse globales sont donc définies dans cette norme. La distribution de masse à l'intérieur d'un châssis et d'un bac, toutefois considérée comme 'spécifique à l'application', est ici définie dans son 'utilisation prévue'. Mots clés: châssis, bacs, unités enfichables, essai sismique

Mehanske konstrukcije za elektronsko opremo - Preskusi za IEC 60917 in IEC 60297 - 5. del: Potresni preskusi za šasije, okvire in vtične enote (IEC 61587-5:2013)

EN IEC 61587-5 določa potresne preskuse za šasije, okvire in vtične enote, kot jih določajo standardi iz serij IEC 60297 in IEC 60917. V celoti ali v delih velja le za mehanske strukture šasij, okvirov in vtičnih enot elektronske opreme v skladu s standardi iz serij IEC 60297 in IEC 60917 ter ne velja za elektronske komponente, opremo ali sisteme znotraj mehanskih struktur. Cilj tega standarda je določiti raven fizične celovitosti šasij, okvirov in vtičnih enot v skladu s standardi iz serij IEC 60297 in IEC 60917, ki lahko zagotovijo raven preživetja za ohranjanje delovanja med seizmičnimi pojavi in po njih. Uporabniku naj bi zagotovil visoko raven samozavesti pri izbiri pripomočkov, ki bodo ustrezali njegovim potrebam. Šasije, okviri in vtične enote iz serij IEC 60297 in IEC 60917 so na voljo v različnih velikostih, imajo različno težo in različno raven mehanične kompleksnosti, zato ni mogoče določiti enotne minimalne zahteve potresnega preskusa za vse kategorije teže. Zato ta standard določa splošne kategorije teže. Vendar se šteje, da je porazdelitev mase znotraj šasije in okvirov „namenjena določenemu načinu uporabe“, zato je določena kot „predvidena uporaba“. Enoosna ali triosna pospešitev za potresno preskušanje je izbirna.

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,
