Annotation of standard text IEC 63522-13-ed.1.0 :
IEC 63522-13:2024 is used for testing electromechanical elementary relays (electromechanical relays, reed relays, reed contacts, reed switches and technology combinations of these) and for evaluating their ability to perform under expected conditions of transportation, storage and all aspects of operational use. This document defines a standard test method to simulate impacts of sulfuric atmospheres to relays. The test conditions simulate an artificial situation and allow a performance comparison for usability of the devices under test (DUT) with regard to known and existing switching solutions. The test is a static test without actual operation of the DUT to simulate a worst-case scenario for corrosion, since corrosion increases over time. The corrosion layer can potentially create contact sticking, increase resistance or other undesired effects in the relay. Those aspects can be affected by DUT actuations during the test, which can destroy the corrosion layers or hide relevant long-term effects. In addition to polluted atmospheres, the suitability of the DUT for use and/or storage in corrosive atmospheres can be assessed in a salt-laden atmosphere as described in IEC 63522-44. Le IEC 63522-13:2024 traite des essais des relais electromecaniques elementaires (relais electromecaniques, relais a lames souples, contacts a lames souples et leur combinaisons technologiques) et permet devaluer leur aptitude a fonctionner dans des conditions prevues de transport, de stockage, et tous les aspects dutilisation operationnelle. Le present document definit une methode dessai normalisee qui vise a simuler les impacts des atmospheres sulfuriques sur les relais. Les conditions dessai simulent une situation artificielle et permettent une comparaison des performances en matiere daptitude a lemploi des dispositifs soumis a lessai (DUT, Devices Under Test) par rapport a des solutions de commutation existantes connues. Lessai est un essai statique sans fonctionnement reel du DUT afin de simuler le scenario le plus defavorable en ce qui concerne la corrosion, celle-ci augmentant avec le temps. La couche de corrosion peut potentiellement creer un collage des contacts, une augmentation de la resistance ou dautres effets indesirables dans le relais. Ces aspects peuvent etre alteres par les manouvres du DUT au cours de lessai, qui peuvent detruire les couches ou masquer les effets pertinents a long terme. Outre les atmospheres polluees, laptitude du DUT a etre utilise et/ou stocke dans des atmospheres corrosives peut etre evaluee dans une atmosphere saline, comme cela est decrit dans lIEC 63522-44.
