Environmental testing - Part 3-3: Supporting documentation and guidance - Seismic test methods for equipment

IEC 60068-3-3:2019 applies primarily to electro-technical equipment but its application can be extended to other equipment and to components. In addition, if some type of analysis is always performed when making a seismic qualification, for example for the choice of the representative sample to be tested or for the extension of the seismic qualification from the tested specimen to similar specimens, the verification of the performance of an equipment by analysis or by a combination of testing and analysis can be acceptable but is outside the scope of this document, which is restricted to verification based entirely upon data from dynamic testing. This second edition cancels and replaces the first edition published in 1991. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - the main aim of this revision is to connect the testing level to the seismic activity level of the zone where the equipment could be installed; - a standard shape for the required response spectrum is also given for the general seismic class for which the seismic environment is either not known or is imprecisely known; - Clauses 11 to 15 were renumbered and some adjustments were made as their content is very general and the requirements can be applied both to the general seismic class and to the specific seismic class; - the word “envelope” is replaced with “dominance” and “to envelop” with “to dominate” in order to provide a more precise meaning from a mathematical point of view.

Essais d’environnement - Partie 3-3: Documentation d’accompagnement et recommandations - Méthodes d’essais sismiques applicables aux matériels

L’IEC 60068-3-3:2019 s’applique principalement au matériel électrotechnique mais son application peut s’étendre à d’autres matériels et composants. Par ailleurs, si un certain type d’analyse est toujours effectuée lors de la réalisation d’une qualification sismique, par exemple pour choisir l’échantillon représentatif à soumettre à essai ou pour étendre la qualification sismique du spécimen soumis à essai à des spécimens similaires, la vérification des performances d’un matériel par l’analyse ou par une combinaison d’essais et d’analyses peut être acceptable mais elle n’entre pas dans le domaine d’application du présent document, qui se limite à la vérification uniquement fondée sur les données d’essais dynamiques. Cette deuxième édition annule et remplace la première édition parue en 1991. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - le principal objectif de la présente révision est d’adapter le niveau d’essai au niveau d’activité sismique de la zone où le matériel est susceptible d’être installé; - une forme normalisée du spectre de réponse spécifié est également fournie pour la classe sismique générale pour laquelle l’environnement sismique n’est pas connu ou l’est de manière imprécise; - les Articles 11 à 15 ont été renumérotés et plusieurs ajustements ont été effectués car le contenu de ces articles est très général et les exigences peuvent s’appliquer aussi bien à la classe sismique générale qu’à la classe sismique spécifique; - le terme «enveloppe» est remplacé par «dominance» et «envelopper» par «dominer» afin d’expliciter ces termes du point de vue mathématique.

Okoljsko preskušanje - 3-3. del: Podporna dokumentacija in navodilo - Seizmične preskusne metode za opremo (IEC 60068-3-3:2019)

Ta dokument se uporablja predvsem za elektrotehnično opremo, vendar ga je mogoče uporabljati tudi za drugo opremo in sestavne dele. Dodatno velja naslednje: če se pri pripravi seizmične kvalifikacije vedno izvaja neka analiza, na primer za izbiro reprezentativnega vzorca za preskus ali za razširitev seizmične kvalifikacije s preskušenega vzorca na podobne vzorce, je lahko sprejemljivo preverjanje delovanja opreme z analizo ali s kombinacijo preskušanja in analize, vendar je to zunaj področja uporabe tega dokumenta, ki je omejen na preverjanje na podlagi podatkov iz dinamičnega preskušanja. Ta dokument obravnava zgolj seizmično preskušanje opreme v polni velikosti, ki se lahko preskuša na vibracijski mizi. Seizmično preskušanje opreme je namenjeno izkazovanju njene zmožnosti za izvajanje potrebnih funkcij med in/ali po tem, ko je bila podvržena obremenitvam in premikom zaradi potresa. Namen tega dokumenta je predstaviti nabor metod za preskušanje, ki jih je, kadar tako določa ustrezna specifikacija, mogoče uporabiti za izkazovanje zmogljivosti opreme, za katero se zahteva seizmično preskušanje, katerega glavni cilj je doseganje kvalifikacije.
