Conveyor belts - Transverse flexibility (troughability) - Test method (ISO 703:2017)

ISO 703:2017 specifies a test method for determining the transverse flexibility (troughability) of a conveyor belt, expressed as a ratio, F/L. The method is not suitable or valid for light conveyor belts as described in ISO 21183‑1.

Courroies transporteuses - Flexibilité transversale (aptitude à la mise en auge) - Méthode d'essai (ISO 703:2017)

ISO 703:2017 spécifie une méthode d'essai pour déterminer la flexibilité transversale (aptitude à la mise en auge) d'une courroie transporteuse, exprimée comme le rapport F/L. Cette méthode n'est pas applicable ou valable pour les courroies transporteuses légères décrites dans l'ISO 21183‑1.

Naprave za kontinuirni transport - Trakovi tračnih transporterjev - Prečna upogibnost - Preskusna metoda (ISO 703:2017)

Ta dokument določa preskusno metodo za ugotavljanje prečne upogibnosti
trakov tračnih transporterjev, izraženo kot razmerje F/L. Ta metoda ni primerna oziroma veljavna za lahke trakove tračnih transporterjev, kot so opisani v standardu ISO 21183-1.
OPOMBA: Prečna »upogibnost«, določena z metodo, opisano v tem dokumentu, je le posredno povezana z nasprotno vrednostjo upogibnega modula, kot je določen v standardu ISO 178. Prav tako ne upošteva razlik v »upogibnosti«, značilne za tri- in štiritočkovno upogibanje, ki upošteva upogibno deformacijo in debelino preskušanca.
