Environmental testing - Part 2-85: Tests - Test Fj: Vibration - Long time history replication
IEC 60068-2-85:2019 demonstrates the adequacy of specimens to resist dynamic loads without unacceptable degradation of its functional and/or structural integrity when subjected to the specified vibration test requirements as defined by a time history (long time history replication). These can either be recorded in measurement exercises or generated artificially. In both cases, this method allows for generating a test tailored to very specific applications.

Essais d'environnement - Partie 2-85 : Essais - Essai Fj: Vibrations - Reproduction dans le temps par accélérogrammes
L'IEC 60068-2-85:2019 a pour objet de démontrer la capacité des spécimens à résister aux charges dynamiques sans dégradation inacceptable de leur intégrité de fonctionnement et/ou de structure, lorsqu'ils sont soumis aux exigences d'essais de vibrations spécifiées, définies par un accélérogramme (reproduction des vibrations dans le temps). Ces vibrations peuvent être enregistrées lors de sessions de mesure ou être générées artificiellement. Dans les deux cas, cette méthode permet de réaliser un essai adapté à des applications bien spécifiques.
Okoljski preskusi - 2-85. del: Preskusi - Preskus Fj: Vibracije - Dolga časovna replikacija (IEC 60068-2-85:2019)
Ta dokument izkazuje primernost primerkov glede odpornosti proti dinamičnim obremenitvam brez nesprejemljivega poslabšanja funkcionalne in/ali strukturne celovitosti, kadar so izpostavljeni podanim zahtevam preskušanja vibracij, kot določa časovna zgodovina (dolga časovna replikacija). Te so lahko zabeležene pri izvajanju meritev ali pa so ustvarjene umetno. V obeh primerih ta metoda omogoča ustvarjanje preskusa, ki je prilagojen zelo specifičnim uporabam. Tipični načini uporabe so preskusi, pri katerih je potrebno zelo specifično deterministično prehodno, periodično ali naključno vzbujanje in značilnosti gibanja niso zajete v drugih preskusnih standardih. To vključuje časovne zgodovine, ki niso dobro predstavljene v standardnih preskušanjih z udarci iz standarda IEC 60068-2-27 [2] ali v splošnem opisu spektra odzivov na udarce iz standarda IEC 600682- 81 [3], periodične vibracije, ki niso zajete v sinusoidni valovni obliki iz standarda IEC 60068-2-6, in naključne vibracije, ki niso zajete v opisu Gaussovih ali ne-Gaussovih (visoka sploščenost) naključnih širokopasovnih vibracij iz standarda IEC 60068-2-64. Vendar pa je uporabnik seznanjen, da dolga časovna replikacija uporablja deterministično časovno zgodovino. Simulacija morebitnih naključnih vibracij je približno zajeta z navidezno naključnostjo. Poleg tega so pri tej preskusni metodi možni dodatni preskusi kombiniranega delovanja z ustvarjanjem časovnih zgodovin, ki predstavljajo zahtevane preskusne signale. To vključuje zelo zahtevne preskuse. Namen tega preskusa je drugačen od standarda IEC 60068-2-57 [4]. Namen standarda IEC 60068-2-57 je ocenjevanje prehodnih vibracij s povečini sintetizirano časovno zgodovino. Preskus dolge časovne replikacije se v glavnem uporablja za preskus odpornosti in funkcionalnosti z dejansko časovno zgodovino, merjeno v realnem okolju. Uporablja se lahko tudi kot metoda za uporabo simulirane ne-Gaussove časovne zgodovine. Ta dokument se uporablja za primerke, ki so lahko izpostavljeni zelo specifičnim vibracijam zaradi transportnih ali obratovalnih okolij, na primer v letalih, vesoljskih plovilih in kopenskih vozilih. Zlasti je namenjen nezapakiranim primerkom in predmetom v njihovem transportnem vsebniku, pri čemer se slednji obravnava kot del samega primerka. Kadar pa je predmet zapakiran, se sam predmet obravnava kot izdelek, izdelek in njegova embalaža pa se obravnavata kot preskušanec. Ta dokument se lahko uporablja v povezavi s standardom IEC 60068-2-47 za preskušanje zapakiranih izdelkov. Čeprav je primarno namenjen elektrotehničnim primerkom, ta dokument ni omejen nanje in se lahko poljubno uporablja na drugih področjih (glej dodatek A). Ta dokument se uporablja za enoosno vzbujanje.

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. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for
