RC Series Dead Weight Creep & Rupture Testing Machine are designed and built for testing the creep properties and creep rupture strength on ferrous metal, nonferrous metal and their alloy that subjects to constant tensile load at a certain temperature at the specified time interval. It is designed according to “ high temperature creep & rupture strength GB/2039-1997” National Standard. Meanwhile, it conforms to ISO204/1997 International Standard and HB5151-96 Aviation Industrial Standard. It can offer liable test/inspection certificate for aviation Industry & other special materials property that should endure high temperature.
