ANSI S2/WG4

Characterization of the Dynamic Mechanical Properties of Viscoelastic Polymers

Chair: W. Madigosky

Vice-Chair: James Dlubac

Scope: Development and maintenance of standards for measurement procedures, instrument calibration, data processing algorithms, and data reporting formats for dynamic properties of viscoelastic polymers. Properties of interest include the complex shear, Young’s Modulus, Bulk Modulus, the Lamé constants, Poisson’s ratio, and the frequency-temperature shift functions obtained through application of the time-temperature superposition principle.

Responsible for the following published standards:

• ASA/ANSI S2.8 – Technical Information Used for Resilient Mounting Applications
• ASA/ANSI S2.9 – Parameters for Specifying Damping Properties of Materials and System Damping
• ASA/ANSI S2.21 Method for Preparation of a Standard Material for Dynamic Mechanical Measurements
• ASA/ANSI S2.22 – Resonance Method for Measuring the Dynamic Mechanical Properties of Viscoelastic Materials
• ASA/ANSI S2.23 – Single Cantilever Beam Method for Measuring the Dynamic Mechanical Properties of Viscoelastic Materials
• ASA/ANSI S2.24 – Graphical Presentation of the Complex Modulus of Viscoelastic Materials
