This is an indicator of how efficiently a material loses energy to molecular rearrangements and internal friction. The values given in parentheses are for information only. The values given in parentheses are for information only. 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.

Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. In Flexure Dual Cantilever Beam.

Signicance and Use 5. By means of our testing expertise and modular product design, we will help find the solution that is right for you. Auditing Consulting Sourcing Training. Tan Delta peaks below the Tg asgm a material on a DMA curve are often used to determine how well a material will stand up to impact.

ASTM D4065 Plastic Dynamic Mechanical Properties | Testing Machine

NOTE 4—Preferably, tests conducted over a temperature range should be performed in incremental steps or at a rate slow enough to allow temperature equilibrium throughout the entire specimen. Link to Active This axtm will always route to the current Active version of the standard. Various techniques for determination of Tg by DMA: The time to reach equilibrium will depend upon the mass of atm particular specimen and the gripping arrangement.

The values given in brackets are for information only. Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.

They typically operate in one of seven oscillatory modes: Any temperature programmer should be sufficiently stable to permit measurement of sample temperature to D Test Method for Plastics: A maximum is observed for the loss modulus, as well as for the tan delta curve, in the transition region.

It incorporates laboratory practice for determining dynamic mechanical properties of plastic specimens subjected to various oscillatory deformations on a variety of instruments of dd4065 type commonly called dynamic mechanical analyzers or dynamic thermomechanical analyzers.

Plots of the elastic or loss moduli, or both, are indicative of viscoelastic characteristics of the specimen. D Terminology for Plastics: These moduli are functions of temperature or frequency in plastics, and change rapidly at particular temperatures or frequencies.

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. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.

In transition regions, experience has indicated that the specimen temperature should be read to Measures displacement for axial tensile, compression, and cyclic testing Gage lengths from 10 mm to 50 mm 0. In Flexure Dual Cantilever Beam. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The elastic modulus of plastic materials is dependent on temperature, time or frequency, or both.

Clearly label the abscissa with title and units of measurement. Validating the specifications, value and safety of your raw materials, products and assets. 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.
