By the linear viscoelastic theory in the textbook of viscoelasticity, the viscoelastic parameters obtained by different viscoelastic tests can be interconversion. However, this interconversion is based on that theory, the interconversion of the experimental data have not seen yet. In this study, the viscoelastic tests were carried out with different environment and same test conditions. And also we carried out the viscoelastic tests with the same testing apparatus and using the same materials. The results showed the difference in the environment on the viscoelastic tests, the silicon oil environment more progressed the creep behavior than the air environment. This is because that the silicon oil's thermal conductivity is one fourth of the air, and the heat generated with the deformation could not escape from the surface of the materials. In addition, the static bending tests were carried out with different strain rate and stress rate at elevated temperature. The results of static bending tests were converted to the creep compliances, then the results were compared with master curve of short term creep tests and 1 month long term creep tests. The results shows the good agreement between the master curve and long term creep tests. However the creep compliances obtained by static bending tests showed the different creep behaviors.
