I have been searching for ASTM/ISO standard procedure to determine the tensile properties of shape memory filament used for 3D printing. I have come across ASTM D638 but this procedure uses 3D printed dog bone specimen. I want to test the filament as it is. Another standard is ISO 23523-2021, but it is used for fiber-reinforced cementitious composites (FRCCs), but PLA/TPU does not come under the umbrella of FRCC. Any expert opinion is highly appreciated. Thank you.
