E Clip On Axial Extensometer. The values given in brackets are for information only.

NOTE 4—Preferably, tests conducted over a temperature range should be performed in incremental steps or at a d0465 slow enough to allow temperature equilibrium throughout the entire specimen. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

For example, while thick specimens of low modulus materials are suitable for measurement, thin specimens of high modulus materials d406 required.

In Flexure Three-Point Bending. These moduli are functions of temperature or frequency in plastics, and change rapidly at particular temperatures or frequencies. ASTM D outlines the general concerns for plastic dynamic testing and references other ASTM testing standards for specific dynamic testing procedures.

Ast, Mechanical Properties Melt Rheology. The deformation strain shall be applied and then released, as in free-vibration devices, or continuously applied, as in forcedvibration devices see Table 1. ASTM D is a practice for gathering test data during dynamic mechanical loading on plastic materials.

Auditing Consulting Sourcing Training. It incorporates laboratory practice for xstm 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. Specific hazards statements are given in Section 8.

DMA identifies transition regions in plastics, such as the glass transition, and may be used for quality control or product development.

Refer to EEand E for additional details on calibration. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the f4065 address or at phonefaxor service astm. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Standards can be obtained from appropriate standards authorities. The values given in parentheses are for information only.

Link to Active This link will always route to the current Active d40065 of the standard. It is the responsibility of the user of this practice ashm establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

The effect of heating rate is observed by running specimens at two or more rates and comparing the elastic and viscous property results obtained. 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. Results are typically provided as a graphical plot of G’, G”, and Tan D versus temperature.

Elastic or loss moduli, or both of the specimen are measured while varying time, temperature of the specimen or frequency of the oscillation, or both the latter. These moduli are functions of temperature or frequency in plastics, and change rapidly at particular temperatures or frequencies. In Flexure Three-Point Bending.

Referenced Documents purchase separately The documents listed below are referenced within the subject d4605 but are not provided as part of the standard. Note 1 — This practice is equivalent to ISO —1. The abscissa should be clearly labeled with title and units of measurement.

A maximum is observed for the loss modulus, as well as for the tan delta curve, in the transition region. A superscript epsilon e indicates an editorial change since the last revision or reapproval. D Terminology for Plastics: If some heat treatment is applied to the specimen to obtain this preferred analytical form, this treatment shall be noted in the report. Specic hazards statements are given in Section 8. They typically operate in one of seven oscillatory modes: The regions of rapid moduli change are normally referred to as transition regions.

Various techniques for determination of Tg by DMA: NOTE 2—The particular method for measurement of elastic and loss moduli depends upon the operating principle of the instrument used.
