Railway applications - Axlebox lubricating greases - Part 1 : method to test the ability to lubricate ordinary-speed vehicles with speeds up to 200 km/h and high-speed vehicles with speeds up to 300 km/h

Le présent document spécifie une méthode d'essai et présente les critères d'acceptation pour la détermination du pouvoir lubrifiant des graisses destinées à être utilisées pour la lubrification des roulements de boîte d'essieu. Le pouvoir lubrifiant, lié en premier lieu à la capacité des graisses lubrifiantes à protéger contre l'usure, est déterminé sur un banc d'essai permettant d'étudier la lubrification des roulements à rouleaux. L'usure des galets des roulements à rouleaux, le comportement en friction et la température pendant l'essai servent à l'analyse comparative des graisses lubrifiantes.
