Plastics. Determination of dynamic mechanical properties - Tensile vibration. Sonic-pulse propagation methodWhat is ISO 6721 9 Tensile vibration of plastic about? ISO 6721 9 is the ninth part of the ISO 6721 multi series on dynamic mechanical properties of plastic. ISO 6721 9 describes a pulse propagation method for determining the storage component of the complex tensile modulus E' of polymers at discrete frequencies typically in the range of 3 kHz to 10 kHz. The method is suitable for measuring materials with storage moduli in the range 0,01 GPa to 200

it is vital that everyone uses the same method to measure them
