Railway infrastructure - Rail fastening systems - Part 7: Test method for clamping force and uplift stiffness (ISO 22074-7:2021)
This document specifies the laboratory test procedure for determining the clamping force exerted by the fastening system on the foot of the rail by measuring the force to separate the rail foot from its immediate support. When required, the procedure is also used to determine the uplift stiffness of the fastening system.
It is applicable to systems with and without baseplates on all types of sleepers, bearers or elements of ballastless track. The test does not determine the security of the fastening components fixed into the sleeper or other fastening system support.
This test procedure applies to a complete fastening assembly. It is not applicable to fastening systems for embedded rail or other fastening systems which do not act on the foot of the rail.

Infrastructure ferroviaire - Systèmes de fixation du rail - Partie 7: Méthode d'essai pour la détermination de l'effort d'application au patin du rail et la rigidité au soulèvement (ISO 22074-7:2021)
Le présent document spécifie la procédure d'essai en laboratoire qui permet de déterminer l'effort d'application au patin du rail exercé par le système de fixation sur le patin du rail en mesurant l'effort nécessaire pour séparer le patin du rail de son support immédiat. Si nécessaire, la procédure est également utilisée pour déterminer la raideur de soulèvement du système de fixation. Elle s'applique aux systèmes avec et sans selles, sur tous types de traverses, de supports ou d'éléments de voie sans ballast. L'essai ne détermine pas le niveau de sécurité des composants de fixation attachés à la traverse ou à tout autre support du système de fixation.
Cette procédure d'essai s'applique aux systèmes de fixation complets. Elle ne s'applique pas aux systèmes de fixation destinés aux rails enrobés ou aux autres systèmes de fixation qui n'agissent pas sur le patin du rail.
