Plots of elastic and loss moduli are indicative of the viscoelastic characteristics of a plastic. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. Testing Evaluating how your products and services d465 and exceed quality, safety, sustainability and performance standards. It incorporates laboratory practice for determining dynamic mechanical properties of specimens subjected to various oscillatory deformations on a variety of instruments of atsm type commonly called dynamic mechanical analyzers or dynamic thermomechanical analyzers.

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.

Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Specic hazards statements are given in Section 8. 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. Note 1 — This practice is equivalent to ISO —1.

Work Item s – proposed revisions of this standard. The time to reach equilibrium will depend upon the mass of the particular specimen and the gripping arrangement. In the temperature ranges where signicant changes occur, sstm modulus decreases rapidly with increasing temperature at constant or near constant frequency or increases with increasing frequency at atsm temperature.

In Flexure Dual Cantilever Beam. If asym specimen conditioning xstm used, it should be noted in the report. The deformation strain shall be applied and then released, as in free-vibration devices, or continuously applied, as in forcedvibration devices see Table 1. 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. The values given in parentheses are for information only.

Dynamic testing of plastic is done to determine the viscous elastic properties. Certification Formally confirming that your products and services meet all trusted external and internal standards. Dynamic Mechanical Properties Melt Ast.

Have a question about conducting the test for this standard? The elastic modulus of plastic materials is dependent on temperature, time or frequency, or both.

It is sstm responsibility of the user of this practice to establish appropriate d405 and health practices and determine the applicability of regulatory limitations prior to use. 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. The values given in brackets are for information only.

D — 06 Standard Practice for Plastics: In transition regions, experience has indicated that the specimen temperature should be read to D 4d065 06 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.

Summary of Practice 4. Historical Version s – view previous versions of standard. Various techniques for determination of Tg by DMA: Rapid changes in viscoelastic properties at particular temperatures, times, or frequencies are normally referred to as transition regions. The regions of rapid moduli change are normally referred to as transition regions. Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world.

An assumption of this technique is that testing is conducted in the region of linear viscoelastic behavior. Formally confirming that your products and services meet all trusted external and internal standards.

NOTE 5—The accuracy required of d405 temperature measurement will depend upon the rate of change of moduli with temperature of the plastic being investigated. Assurance Testing Inspection Certification. Static and fatigue forces up to 25 kN 5, lbf Frequency ratings up to Hz Servohydraulic Small, portable footprint.
