GB/T 33061.4-2023 Plastics—Determination of dynamic mechanical properties—Part 4:Non-resonance method under tensile vibration
Abstract
This document describes a forced non-resonant method for measuring the complex tensile modulus E of plastics in the frequency range of 0.001 Hz to 100 Hz.
Note: Higher frequencies may lead to significant errors in the measured dynamic performance (see 9.5.1 and 10.1.2).
This document is suitable for measuring the dynamic storage modulus of 0.01 GPa to 5 GPa, and can also be used to study plastics beyond this modulus range, but other non-tensile deformation modes can be used to more accurately measure their dynamic mechanical properties [i.e., shear mode with G' < 0.01 GPa (see GB/T 33061.6), bending mode with E' > 5 GPa (see ISO 6721-3 or GB/T 33061.5)].
This document is particularly suitable for measuring loss factors greater than 0.02, so as to study the changes in the dynamic performance of the glassy and rubbery relaxation regions of most plastics with temperature and frequency (see GB/T 33061.1).
