Abstract
Overview
ISO 22074-8:2022 specifies laboratory test methods for vertical stiffness of rail fastening components. It defines procedures to measure the and of , and . The standard focuses on controlled laboratory tests that simulate the vertical loading experienced in railway track under passing wheels and bogies. It does not cover stiffness testing above 30 Hz.
