ASTM D4065 PDF

Full Description 1. 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. Plots of elastic and loss moduli are indicative of the viscoelastic characteristics of a plastic. These moduli are functions of temperature or frequency in plastics, and change rapidly at particular temperatures or frequencies. The regions of rapid moduli change are normally referred to as transition regions.

Plots of elastic and loss moduli are indicative of the viscoelastic characteristics of a plastic. These moduli are functions of temperature or frequency in plastics, and change rapidly at particular temperatures or frequencies.

The regions of rapid moduli change are normally referred to as transition regions. Without changing the observed data, reporting in full as described in this practice the conditions under which the data were obtained will enable apparent differences observed in another study to be reconciled.

An assumption of this technique is that testing is conducted in the region of linear viscoelastic behavior. The values given in parentheses are for information only.

It is the responsibility of the user of this practice to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazards statements are given in Section 8.

Note 1—This practice is equivalent to ISO —1. Significance and Use 5. A plot of the elastic modulus and loss modulus of material versus temperature provides a graphical representation of elasticity and damping as a function of temperature or frequency.

In the temperature ranges where significant changes occur, elastic modulus decreases rapidly with increasing temperature at constant or near constant frequency or increases with increasing frequency at constant temperature.

A maximum is observed for the loss modulus, as well as for the tan delta curve, in the transition region. Therefore, consult the appropriate material specification before using this practice.
