BS EN 13146-9:2009+A1:2011EN 13146-9:2009+A1:2011 (E) 4 Introduction This part of EN 13146 brings together test methods for measuring the stiffness of p
23、ads and fastening assemblies under static, low frequency and 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
24、laboratories have the equipment and the experience necessary 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 incl
25、uded. The procedure in EN 15461, which involves testing a length of track incorporating the fastening assemblies under test can be used. BS EN 13146-9:2009+A1:2011EN 13146-9:2009+A1:2011 (E) 5 1 Scope This European Standard specifies laboratory test procedures to determine the static and dynamic sti
26、ffness of rail pads, baseplate pads and complete rail fastening assemblies. The procedures for dynamic stiffness cover low and high frequencies. 2 Normative references The following documents are indispensable for the application of this document.
