-
— the transmission of vibration in the lower part of the audible frequency range (typically 20 Hz to 500 Hz) to a structure which may, for example, radiate unwanted fluid-borne sound (airborne, waterborne or others), and
-
— the transmission of low-frequency vibrations (typically 1 Hz to 80 Hz), which may, for example, act upon human subjects or cause damage to structures of any size when vibration is too severe.
NOTE 1 In practice, the size of the available test rig(s) can restrict the use of very small or very large resilient supports.
NOTE 2 Samples of continuous supports of strips and mats are included in this method. Whether or not the sample describes the behaviour of the complex system sufficiently is the responsibility of the user of this part of ISO 10846.
NOTE 3 Because of the large variety of test rigs and test elements, fUL is variable. In this part of ISO 10846, the adequacy of the test rig is not defined for a fixed frequency range, but on the basis of measured data, as described in 6.1 to 6.4.
NOTE 1 When a resilient support has no parallel flanges, an auxiliary fixture is included as part of the test element to arrange for parallel flanges.
NOTE 2 The arrows indicate the load direction.
