Optical circuit boards - Basic test and measurement procedures - Part 2-5: Flexibility test for flexible opto-electric circuits
This part of IEC 62496-2 defines a test method for folding flexibility inspection of flexible opto-electric circuits with a MIT folding endurance tester and presents a guideline for a step stress test method for finding the predetermined minimum mechanical folding radii below which the flexible opto-electric circuits can be damaged by intended folding distortion. Here, test samples are used instead of products for the flexibility test of their flexible opto-electric circuits, and the test samples have the same layer structure as the products.

IEC 62496-2-5:2022 définit une méthode d’essai pour l’examen de la flexibilité au pliage des circuits optoélectriques souples au moyen d’un appareil de contrôle de la flexibilité, et fournit un guide qui présente une méthode d’essai sous contrainte échelonnée destinée à déterminer les rayons de pliage mécanique minimaux prédéterminés en deçà desquels les circuits optoélectriques souples peuvent être endommagés par la distorsion induite par un pliage intentionnel. Des échantillons d’essai sont utilisés ici à la place des produits pour l’essai de flexibilité de leurs circuits optoélectriques souples, et ces échantillons d’essai sont constitués du même matériau, ont la même structure de couches et utilisent la même technologie et les mêmes équipements de traitement que les produits eux-mêmes.

Ta del standarda IEC 62496-2 opredeljuje preskusno metodo za preskušanje upogljivosti zvijavih optoelektričnih vezij z napravo za preskušanje vzdržljivosti pregibanja MIT in predstavlja smernice za metodo stopenjskega preskusa obremenitve, da se ugotovi vnaprej določen minimalni mehanski zgibni polmer, pod katerim se zvijava optoelektrična vezja lahko poškodujejo zaradi namernega zvijanja. Tukaj se namesto izdelkov uporabljajo preskusni vzorci za preskušanje prožnosti njihovih zvijavih optoelektričnih vezij. Preskusni vzorci imajo enako strukturo plasti kot izdelki.

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 collabor
