ÖNORM EN ISO 10846-1

This part of ISO 10846 explains the principles underlying parts 2 to 5 of ISO 10846 for determining the transfer properties of vibration isolators from laboratory measurements, and provides assistance in the selection of the appropriate part of this series. This part of ISO 10846 is applicable to vibration isolators which are used to reduce: a) the transmission of audiofrequency vibrations (structure-borne sound, 20 Hz to 20 kHz) to a structure which may, for example, radiate fluid-borne sound (airborne, waterborne, or other); b) the transmission of low frequency vibrations (typically 1 Hz to 80 Hz) which may, for example, act upon humans or cause damage to structures when vibration is too severe. The data obtained with the measurement methods which are outlined in this part of ISO 10846 and further detailed in parts 2 to 5 of ISO 10846 can be used for: product information provided by manufacturers and suppliers; information during product development; quality control; computation of the transfer of vibrations through isolators. The conditions for the validity of the measurement methods are a) linearity of the vibrational behaviour of the isolator (this includes elastic elements with non-linear static loaddeflection characteristics as long as the elements show approximate linearity for vibrational behaviour for a given static preload); b) the contact interfaces of the vibration isolator with the adjacent source and receiver structures can be considered as point contacts.
