What is ISO 6721-7 - Dynamic mechanical properties through Torsional vibration about?
ISO 6721-7 is the seventh part of the series on plastics which discusses the method to determine dynamic mechanical properties of plastic. ISO 6721-7 describes a torsional, non-resonance method for determining the components of the shear complex modulus G* of solid polymers in the form of bars or rods at frequencies typically in the range 0,001 Hz to 100 Hz.
Who is ISO 6721-7 - Dynamic mechanical properties through Torsional vibration for?
ISO 6721-7 on the determination of dynamic mechanical properties of plastic is relevant to:
- Plastic industry
- Plastic testing laboratory
Why should you use ISO 6721-7 - Dynamic mechanical properties through Torsional vibration?
The determination of dynamic mechanical properties is a technique that is widely used to characterize material properties as a function of temperature, time, frequency, stress, atmosphere, or a combination of these parameters.
ISO 6721-7 clearly gives the visualization of the suitable loading assemblies for determining dynamic shear moduli by a forced torsional non-resonance method. This process helps the end-user maintain stiffness and inertia in the product.
ISO 6721-7 allows the engineers to have a better understanding of the dynamics of rotating equipment enabling them to troubleshoot and validate performance.
