Many analytical methods are available within the family
of thermoanalytical techniques for characterizing roof
membrane materials. These techniques include classical
methods, such as differential scanning calorimetry
(DSC), differential thermal analysis (DTA), and
thermogravimetry (TG), and modern methods, such as
thermomechanical analysis (TMA), torison pendulum
analysis (TPA), and dynamic mechanical analysis (DMA).
This paper summarizes the work of the RILEM/CIB Joint
Committee on Membrane Roofing Systems - Thermal Analysis
Task Group on TG and DMA Testing of Roofing Membrane
Materials. The recommendations from the committee on
how TG and DMA can be used to study new and in-service
bituminous-and polymer-based roof membrane materials are
