Wire torsion testing machine for Metallic Materials

Principle

Unidirection torsion:the specimen even turn 360 degrees in one direction coil self axis,is for one time torision to recommended times,or specimen rupture

Bidirectional torsion: he specimen even turn 360 degrees in one direction coil self axis,is one time torision to recommended times,torsion in opposite direction the same times or specimen ruputure.

Main usage:Wire torision testing machine ,used to make torsion test for metallic wire with diameter0.1-10mm.,It can be used to measure the capacity of plastic deformation and display surfacial and interior defects in unidirection and bidirection torsion and interior defects in unidirection and bidirection torsion

Applicable Standard:Wire torision testing machine is apply to GB/T239-1999<metallic wire torision test methods>,also apply to ISO7800:2003< metallic wire unidirection torision test metho t;and ISO 9649:1990<metallic wire bidirection torision test metho t;.
