The case study for tension test PT in Korea

Tensile properties are the most fundamental properties for the mechanical structure design. Due to industrial development in all areas requires sophisticated and smart, lightweight, high-quality products continues to increase appetite. Therefore, designer was necessary more accurate mechanical properties. To meet these requirements, In the field of mechanical engineering has a lot of effort. In this study, several testing laboratory ware proficiency testing(PT) in Korea to the ability of the tensile test, to the reliability of testing machine and to assessment the skill level of a tester. Also propose each laboratory problems and improvements on the basis of PT test results.
