Results of the uniaxial tensile tests on necked PA12 tubes at 23 °C and 37 °C for specimens tested without water, in water, in a saline solution. a Nominal stress vs. strain curves. Sample lying in the center of the of the respective curve array. b Median values of the Young’s Modulus for 23 °C and 37 °C with width of the IQR. c Median values of \({\sigma }_{\mathrm{y}}\) with width of the IQR
