Mechanical vibration and shock. Guidelines for dynamic tests and investigations on bridges and viaducts Ingestion-build-256245 Note1: ISO 18639‑4 does not1 Scope This International Standard provides guidelines for dynamic tests and investigations on bridges and viaducts. It classifies the testing as a function of construction and usage, indicates the types of investigation and control for individual structural parts and whole structures, lists the equipment required for excitation and measurement, and classifies the techniques of investigation with reference to suitable methods for signal processing,
