Dear Jorgen
Thanks a lot for sharing your knowledge about mechanics of polymers!
I have a question regarding the condition of DMA tests in term of relative humidity (RH).
How important is to keep the RH constant when one changes the T in each DMA test? Does it depend on the type of material ? Or If each DMA test is relatively short, then maybe the RH effect can be ignored?
Best regards,Reza

Most people ignore the influence of the relative humidity during a DMA test. For most materials it is a second order effect.
