ASTM WK38116

    Revision of C747 - 93(2010)e1 Standard Test Method for Moduli of Elasticity and Fundamental Frequencies of Carbon and Graphite Materials by Sonic Resonance

    (What is a Work Item?)

    Active Standard: C747 - 93(2010)e1

    Developed by Subcommittee: D02.F0 | Committee D02 | Contact Staff Manager



    WK38116

    1. Rationale

    Currently the standard is written for sonic resonance excitation only and we wish to expand the standard to include impulse excitation. The fundamental frequency of vibration and elastic modulus are independent of the method of excitation. An ILSS will be conducted and a precision and bias statement developed since there is currently not one included.
