Environmental testing - Part 2-18: Tests – Test R and guidance: Water
NEW!IEC 60068-2-18:2017 is available as IEC 60068-2-18:2017 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60068-2-18:2017 provides methods of test applicable to products which, during transportation, storage or in service, can be subjected to falling water drops, impacting water, immersion or high pressure water impact. The primary purpose of water tests is to verify the ability of enclosures, covers and seals to maintain components and equipment in good working order after and, when necessary, under a standardized drop field or immersion in water. These tests are not corrosion tests and cannot be considered and used as such. Established water tests in other standards are not intended to simulate natural rainfall and their quoted intensities are too high to be adopted for that purpose. Therefore, in addition to the high-intensity severities, test R includes an artificial rain test based upon natural conditions but not taking into account high wind speeds generally associated with natural rain. Guidance is given on the applicability of the tests and the severities to be selected. This third edition cancels and replaces the second edition published in 2000. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a. addition of the new test method Rb 3.

NEW!IEC 60068-2-18:2017 est disponible sous forme de IEC 60068-2-18:2017 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L’IEC 60068-2-18:2017 spécifie les méthodes d’essai applicables aux produits qui, pendant leur transport, leur stockage, ou alors qu’ils sont en service, peuvent être soumis à des chutes de gouttes d'eau, à des projections d’eau, à une immersion ou à des projections d’eau à haute pression. Le but premier des essais d’eau est de vérifier l’aptitude des enveloppes, des couvercles et des joints d’étanchéité à maintenir les composants et les matériels en bon état de marche après et, si besoin, pendant un arrosage par des gouttes d’eau ou une immersion dans l’eau normalisée. Ces essais ne sont pas des essais de corrosion et ne peuvent pas être considérés ou utilisés comme tels. Les essais d’eau déjà établis dans d’autres normes ne sont pas destinés à simuler les chutes de pluie naturelles et leurs intensités correspondantes sont trop élevées pour être utilisées dans ce but. En conséquence, en plus des sévérités de forte intensité, l’essai R comprend un essai de pluie artificielle basé sur des conditions naturelles, mais sans tenir compte des grands vents qui sont généralement associés à la pluie naturelle. Des préconisations sont données sur l’applicabilité des essais et sur les sévérités à choisir. Cette troisième édition annule et remplace la deuxième édition parue en 2000. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a. ajout de la nouvelle méthode d'essai Rb 3.
Okoljsko preskušanje - 2-18. del: Preskusi - Preskus R in navodilo: Voda (IEC 60068-2-18:2017)
Ta del standarda IEC 60068 podaja preskusne metode za uporabo pri proizvodih, ki so lahko med prevozom, skladiščenjem ali uporabo izpostavljeni padajočim vodnim kapljam, vplivom vode, potopitvi ali vodnim curkom pod visokim tlakom. Osnovni namen preskusov z vodo je preverjanje, ali so ohišja, pokrovi in tesnila zmožni zagotoviti ustrezno delovno stanje sestavnih delov in opreme po (ter po potrebi pri) standardiziranem kapljičnem polju ali potopitvi v vodo.
Ti preskusi niso preskusi korozivnosti in jih ni mogoče obravnavati ali uporabljati kot take. Vzpostavljeni preskusi z vodo v drugih standardih niso namenjeni simulaciji naravnega dežja in njihove navedene intenzitete so previsoke za ta namen. Poleg zahtevnosti visoke intenzitete preskus R zaradi tega vključuje preskus z umetnim dežjem na podlagi naravnih pogojev, vendar ob neupoštevanju visokih hitrosti vetra, ki so običajno povezane z naravnim dežjem. Standard podaja smernice glede uporabnosti preskusov in izbire zahtevnosti.
