Abstract: Method for tensile testing of superplastic materials had been standardized as ISO 20032: 2007, which is based on JIS, Japanese Industrial Standard, H 7501 and H 7505. These standards specify the test specimens of S-and R-types. Recently, the working group organized by Osaka Science and Technology Center, Japan, proposed a revised version of ISO 20032 with several corrections. After systematic review and voting at ISO/TC (Mechanical Testing of Metals) 164/SC2 (Ductility Testing), the second edition of ISO 20032 was published in 2013. Now, a working group has been set for proposing a revised version of JIS corresponding to ISO 20032: 2013. This paper reports the constitution process of these ISO and JIS standards.
