Methods of testing plastics - Mechanical properties - Flexural vibration. Non-resonance method Ingestion-build-242630 New materials are being discovered1 Scope This part of ISO 6721 describes a flexural, non resonance method for determining the components of the Youngs complex modulus E* of polymers at frequencies typically in the range 0,01 Hz to 100 Hz. Higher frequency measurements can be made, but significant errors may be obtained in the dynamic properties measured (see 10. 2. 1 and 10. 2. 2). The method is suitable for measuring dynamic storage moduli in the range 10 MPa to 200 GPa. Although
