Organic light emitting diode (OLED) displays - Part 5-2: Mechanical endurance testing methods
IEC 62341-5-2:2013 defines testing methods for evaluating mechanical endurance quality of Organic Light Emitting Diode (OLED) display panels and modules or their packaged form for transportation. It takes into account, wherever possible, the environmental testing methods outlined in specific parts of IEC 60068. The object of this standard is to establish uniform preferred test methods for judging the mechanical endurance properties of OLED display devices.

Afficheurs à diodes électroluminescentes organiques (OLED) - Partie 5-2: Méthodes d’essais d'endurance mécanique
La CEI 62341-5-2:2013 définit des méthodes d'essais pour évaluer la qualité de l'endurance mécanique de modules et de panneaux d'affichage à diodes électroluminescentes organiques (OLED) ou de leur emballage d'expédition. Elle tient compte, dans la mesure du possible, des méthodes d'essais d'environnement indiquées dans des parties spécifiques de la CEI 60068. La présente norme a pour objet d'établir des méthodes d'essais préférentielles uniformes pour juger les propriétés d'endurance mécanique des dispositifs d'affichage OLED.
Prikazovalniki z organskimi svetlečimi diodami (OLED) - 5-2. del: Metode za preskušanje mehanske zdržljivosti (IEC 62341-5-2:2013)
Ta del standarda IEC 62341 določa metode za preskušanje kakovosti mehanske vzdržljivosti plošč in modulov prikazovalnikov z organskimi svetlečimi diodami (OLED) ali transportne embalaže le-teh. Kadar je to mogoče, upošteva metode okoljskega preskušanja, kot je navedeno v določenih delih standarda IEC 60068. Cilj tega standarda je vzpostaviti enotne priporočene preskusne metode za ocenjevanje lastnosti mehanske vzdržljivosti prikazovalnikov z organskimi svetlečimi diodami (OLED). Običajno obstajata dve kategoriji preskusov mehanske vzdržljivosti: tista, ki se nanaša na okolje uporabe izdelka, in tista, ki se nanaša na transportno okolje izdelka v pakirani obliki. Vibracije, udarci, kvazistatična moč, štiritočkovni upogibni preskus in preskus odpornosti proti luščenju so tukaj določene za okolje uporabe, medtem ko se za transportno okolje uporablja preskus s padcem med transportom. Preskusi mehanske vzdržljivosti se lahko razvrstijo tudi tako: preskusi za mobilne telefone, prenosne računalnike ali monitorje in velike televizorje. Upoštevajo se posebne zahteve ali omejitve metod za preskušanje glede na velikost ali uporabo preskusnega vzorca.
