The values given in brackets are for information only. Therefore, consult the appropriate material specication before using this practice. The time to reach equilibrium will depend upon the mass of the particular specimen and the gripping arrangement. Dynamic testing of plastic is done to determine the viscous elastic properties.
A maximum is observed for the loss modulus, as well as for the tan delta curve, in the transition region.
Dynamic Mechanical Analysis ASTM D, D, D
The test specimen is clamped between the movable and stationary fixtures, and then enclosed in d44065 thermal chamber. The regions of rapid moduli change are normally referred to as transition regions.
Summary of Practice 4. Determination and Report of Procedures 1 This standard is issued under the xed zstm D ; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A maximum is observed for the loss modulus, as well as for the tan delta curve, in the transition region. Need help or have a question?
Dynamic Mechanical Properties Melt Rheology. Clearly label the abscissa with title and units of measurement.

Specic hazards statements are given in Section 8. In Flexure Dual Cantilever Beam. An assumption of this technique is that testing is conducted in the region of linear viscoelastic behavior.
Plots of elastic and loss moduli are indicative of the viscoelastic characteristics of a plastic. Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world. Note 1 — This practice is equivalent to ISO —1.

DMA identifies transition regions in plastics, such as the glass transition, and may be used for quality control or product development. It incorporates laboratory practice for determining dynamic mechanical properties of specimens subjected to various oscillatory deformations on a variety of instruments of the type commonly called dynamic mechanical analyzers or dynamic thermomechanical analyzers.
Therefore, consult the appropriate material specification before using this practice. In Flexure Three-Point Bending. Give our test engineers a call today for help configuring the best test machine and accessories according to your standard. Dfor those tests where conditioning is required. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.
This standard has been approved for use by agencies of the Department of Defense. Frequency, amplitude, and a temperature range appropriate for the material are input. For example, while thick specimens of low modulus materials are suitable for measurement, thin specimens of high modulus materials are required. Last previous edition approved in as D – It incorporates laboratory practice for determining dynamic mechanical properties of plastic specimens subjected to various oscillatory deformations on a variety of instruments of the type commonly called dynamic mechanical analyzers or dynamic thermomechanical analyzers.

These moduli are functions of temperature or frequency in plastics, and change rapidly at particular temperatures or frequencies. D Test Method for Plastics: The Analyzer applies torsional oscillation to the test sample while slowly moving through the specified temperature range. ASTM D outlines the general concerns for plastic dynamic testing and references other ASTM testing standards for specific dynamic testing procedures.
