Microcomputer controlled tensile stress relaxation testing machine for steel strand
Application:
This machine is used to do stress-relaxation test of steel strand, galvanized steel wire, indented wire etc
metal materials. The host machine adopts horizontal structure, adjust work space by lead screw, and the
transmission system is inside the machine base, the machine has very high stiffness, which guarantee
the accuracy of test results.
Test standard:
--ISO15630-3: 2010 Steel for reinforcement and prestressing of concrete- Test methods part 3: prestressing steel
--ASTM E328-13: Standard test methods for stress relaxation for materials and structures
--ASTM A416 Standard specification for low-relaxation, seven-wire steel strand for prestressed concrete
