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. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
Give our test engineers a d465 today for help configuring the best test machine and accessories according to your standard. A number in parentheses indicates the year asfm last reapproval.
By means of our testing expertise and modular product design, we will help find d44065 solution that is right for you. Any temperature programmer should be sufficiently stable to permit measurement of sample temperature to Plots of elastic and loss moduli are indicative of the viscoelastic characteristics of a plastic. Mechanical spectrometerB,C Sinusoidal xed or variable frequency Forced constant amplitude; xed or variable frequency-torsional oscillation see Fig.
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.
The regions of rapid moduli change are normally referred to as transition regions. For example, while thick specimens of low modulus materials are suitable for measurement, thin specimens of high modulus materials are required. 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.

Elastic or loss moduli, or both of the specimen are measured while d465 time, temperature of the specimen or frequency of the oscillation, or both the latter. If other specimen conditioning is used, it should be noted in the report.

Formally confirming that your products and services meet all trusted external and internal standards. Last previous edition approved in as D – Current edition approved Dec. Specific hazards statements are given in Section 8. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.

Awtm Formally confirming that satm products and services meet all trusted e4065 and internal standards. D Test Method for Plastics: The elastic modulus of plastic materials is dependent on temperature, time or frequency, or both. 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 impact. C Instruments of this type are available from Rheometric-Scientic, Inc.
The Analyzer applies torsional oscillation to the test sample while slowly moving through the specified temperature range. Assurance Testing Inspection Certification. NOTE 2—The particular method for measurement of elastic and loss moduli depends upon the operating principle of the instrument used. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
A maximum is observed for the loss modulus, as well as for the tan delta curve, in the transition region. The regions of rapid moduli change are normally referred to as transition regions.
