Title

Results of a Round Robin Test Series to Evaluate Complex Moduli of a Selected Damping Material
-
Description
-
A Round Robin test series was conducted to establish the current state of the art in the measurement of complex moduli of polymeric damping materials as functions of frequency and temperature. Several laboratories participated, using a variety of test systems, providing data over the temperature range from -50°C to +100°C, and the frequency range from 1E-5 Hertz to over 10000 Hertz. The paper briefly describes the selection of the test material, the test methods used, and the means used to establish the accuracy of each data set and identify random and systematic errors. The results show the manner in which data from different test techniques can differ and sources are identified for some of these differences. Frequency-temperature analysis of the data is discussed.
