GB/T 33061.5-2023 Plastics—Determination of dynamic mechanical properties—Part 5:Non-resonance method under flexural vibration
Abstract
This document describes a forced non-resonant method for measuring the complex modulus Ef* of plastics in the frequency range of 0.01 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 10 MPa to 200 GPa. This document can study materials with a modulus less than 10 MPa, but using shear vibration can more accurately measure their dynamic mechanical properties (see GB/T 33061.6).
This document is particularly suitable for measuring loss factors greater than 0.02, so as to study the changes in the dynamic performance of most glassy and rubbery relaxation regions with temperature and frequency (see GB/T 33061.1).
