Sample number :4(for example LGJ-720/50)
Test condition sample length:
Length of two end sample:14m
Treatment of two end sample:epoxy resin pouring
Testing valid length of the simultaneity elongation instyument
Rest temperature:20 卤1鈩�
Test precision:
Stress: 卤1%
Strain: 卤0.01mm/5000m
Sample tension:25.59kN(15%RTS)
42.66kN(25%RTS)
59.71kN(35%RTS)
