18、nd high frequency dynamic loading. For measurements at high frequency, the corrected driving point method has been included although it is only valid up to 120 Hz whilst the direct and indirect methods are valid up to 400 Hz. Only a few test laboratories have the equipment and the experience necessa
19、ry to perform the indirect and direct methods. More laboratories should be able to perform the corrected driving point method and for some purposes, measurements up to 120 Hz are adequate. No method for testing at acoustic frequencies is included. The procedure in EN 15461, which involves testing a
20、length of track incorporating the fastening assemblies under test can be used. - - EN 13146-9:2009 (E) 5 1 Scope This European Standard specifies laboratory test procedures to determine the static and dynamic stiffness of rail pads, baseplate pads and complete rail fastening assemblies. The procedur
21、es for dynamic stiffness cover low and high frequencies. 2 Normative references The following documents are indispensable for the application of this document.
