In spite of the various testing activities on superplastic materials, currently available standards on characterising the behaviour of this unique class of materials are limited, and do not agree on several testing issues. Besides, the standards are unable to address some of the important and controversial issues in superplastic materials’ testing, and therefore leave the reader without enough guidelines on those particular ones. In a recent work, a review of the main standards describing the proper method for testing superplastic materials was carried out, and the most critical of un-confronted testing issues were highlighted. And in an effort to tackle those issues, an integrated testing methodology, centred about newly-developed quick-mount testing grips was proposed. Though the methodology was validated for a narrow range of testing conditions, the preliminary results were very promising. Consequently, in this work we further explore the potentials of the methodology through a comprehensive FE and experimental investigation, targeting a wide range of superplastic materials and testing conditions. Refined quick-mount grips, that accommodate testing at extreme temperatures, are first presented. Then the proper specimen geometry is selected based on a set of FE simulations, targeting optimum performance in terms of minimum distortion and material flow in the grip region. Finally, tensile tests are conducted at wide-ranging conditions (deformation rates and temperatures), assessing the effectiveness of the methodology in resolving the targeted issues. To make sure that the developed grips, selected specimen geometry, and proposed methodology are all viable for most metallic superplastic materials, the aforementioned FE simulations and experiments are carried out using three alloys; Ti4Al6V titanium, 5083 aluminium and the AZ31 magnesium alloys. It is hoped that this work will be the prelude of
