BS4449 Bar Computerized Tensile Testing Machine


BS4449 Bar Computerized Tensile Testing Machine

(300kN, 600kN, 1000kN, 2000kN, 0.5 Class)

1. Applications:

WAW-E Series Computerized Electro-hydraulic Servo Universal Testing Machine is newly designed for tensile and bending test of deformed and plain carbon-steel bars. It adopts four column and two screws structure, high stiffness. It uses high accuracy load cell to measure testing force, encoder to measure displacement of work bench, electric extensometer to measure extension. Close loop control software can auto get test tensile strength Rm, yield strength ReH/ ReL, max. testing force Fm, non-proportional extension Rp0.2, elongation rate A%, extension at max. testing force Agt, modulus of elasticity E, etc testing results. In testing standard, it conforms to international standards, like ASTM A615, BS 4449, ISO6892, ASTM E8, ISO15579-2000, ISO679, ISO7438-1985, JIS Z2241 and other international specifications.
