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. This standard has been approved for use by agencies of the Department of Defense. Tan Delta peaks below the Tg of a material on a DMA curve are often used to determine how well a material will stand up to adtm.

Signicance and Use 5. 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. Have a question about conducting the test for this standard? 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? Axtm assumption of adtm technique is that testing is conducted in the region of linear viscoelastic behavior. 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.

It is the responsibility of the user of e4065 practice to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Current edition approved Dec. Specific hazards statements are given in Section 8. wstm

If other specimen conditioning is used, it should be noted in the report. In many cases, a specimen of 0. The test specimen is clamped between the movable and stationary fixtures, and then enclosed in the thermal chamber.

Link to Active This link will always route to the current Active version of the standard. NOTE 5—The accuracy required of the temperature measurement will depend upon the rate of change of moduli with temperature of the plastic being investigated. Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.

In transition regions, experience has indicated that the specimen temperature should be read to 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.

Dfor those tests where conditioning is required. Formally confirming that your products and services meet all trusted external and internal standards. ASTM D is a practice for gathering test data during dynamic mechanical loading on plastic materials.

NOTE 3—It is important to select a specimen size consistent with the modulus of the material under test and capabilities of the measuring apparatus. A superscript epsilon e indicates an editorial change since the last revision or reapproval.

Historical Version s – view previous versions of standard. In Flexure Dual Cantilever Beam. Standards x4065 be obtained from appropriate standards authorities. ASTM D outlines the general concerns for plastic dynamic testing and references other ASTM testing standards for specific dynamic testing procedures. Refer to EEand E for additional details on calibration.

Dynamic Mechanical Analysis ASTM D, D, D

A plot of the elastic modulus and loss modulus of material versus temperature provides a graphical representation of elasticity and damping astk a function of temperature or frequency. They typically operate in one of seven oscillatory modes: Auditing Consulting Sourcing Training.

Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world. Work Item s – proposed d40065 of this standard. Your comments will receive asttm consideration at a meeting of the responsible technical committee, which you may attend.

A number in parentheses indicates the year of last reapproval. Last previous edition approved in as D – This is an indicator of how efficiently a material loses energy to molecular rearrangements and internal friction.

D0465 Validating the specifications, value and safety of your raw materials, products and assets. The effect of heating rate is observed by running specimens at two or more rates and comparing the elastic and viscous property results obtained. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.

December 1, 1 D465 revisions made throughout.

Specic hazards statements are given in Section asm. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Dynamic Mechanical Analysis DMA determines elastic modulus or storage modulus, G’viscous modulus or loss modulus, G” and damping coefficient Tan D as a function of temperature, frequency or time.

These moduli are functions of temperature or frequency in plastics, and change rapidly at particular temperatures or frequencies. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. Active view current version of standard. In the temperature ranges where signicant changes occur, elastic modulus decreases rapidly with increasing temperature at constant or near constant frequency or increases with increasing frequency at constant temperature.
