1. Introduction:
The WSC-300 microcomputer controlled tensile stress relaxation tester is mainly used for the tensile stress relaxation mechanical properties test of metal materials (such as steel strands, PC steel bars and steel wires) at room temperature.
The product meets the requirements of GB/T 10120-1996 Metal Stress Relaxation Test Method and GB/T5224-2003 Prestressed Concrete Strand and ASTM E328-1991 Material and Structural Stress Relaxation Test Method. Related requirements for stress relaxation tests.
