For the purposes of ISO 18437-5:2011, and within the framework of ISO/TC 108, the term dynamic mechanical properties refers to the determination of the fundamental elastic properties, e.g. the complex Young modulus and Poisson ratio, as a function of temperature and frequency.
ISO 18437-5:2011 is applicable to resilient materials that are used in vibration isolators in order to reduce: a) transmission of audio frequency vibrations to a structure, e.g. radiating fluid-borne sound (airborne, structure-borne, or other); b) transmission of low-frequency vibrations which can, for example, act upon humans or cause damage to structures or equipment when the vibration is too severe.
The data obtained with the measurement methods that are outlined in ISO 18437-5:2011 and further detailed in ISO 18437-2 to ISO 18437-4 can be used for: 1) design of efficient vibration isolators; 2) selection of an optimum resilient material for a given design; 3) theoretical computation of the transfer of vibrations through isolators; 4) information during product development; 5) product information provided by manufacturers and suppliers; 6) quality control.
