This part of ISO 10846 specifies a driving point method for determining the low-frequency transfer stiffness for translations of resilient supports, under specified preload. The method concerns the laboratory measurement of vibrations and forces on the input side with the output side blocked, and is called "driving point method". The method is applicable to test elements with parallel flanges (see Figure 1). Resilient elements, which are the subject of this part of ISO 10846, are those, which are used to reduce a) the transmission of vibration in the lower part of the audible frequency range (typically 20 Hz - 200 Hz) to a structure which may, for example, radiate unwanted fluid-borne sound (airborne, waterborne or others); b) the transmission of low-frequency vibration (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. Measurements for translations normal and transverse to the flanges are covered in this part of ISO 10846. The method covers the frequency range from f1 < 1 Hz to the upper limiting frequency fUL. Typically 50 Hz < f UL < 200 Hz.
