NDW-500 Computer Control Electronic Torsion Testing Machine
NDW-500 series of computer screen torsion testing machine is used to do the torsion performance test metal materials, non-metallic materials, composite materials and shaft parts of components. The machine has the characteristics of stable and reliable operation, high adaptability to the environment, large measuring range, high resolution and high precision. Such as the material torsion damage, torsion shear modulus, multi-step torque loading and other tests. With the torque meter, it can measure the shear modulus, the provisions of non-proportional torsional stress.
Mainly applicable to the measurement of quality inspection; automotive, transmission machinery, bolt fasteners, metallurgical steel, machinery manufacturing, civil aviation, universities, research laboratories, commodity inspection arbitration, technical supervision departments, building ceramics, petrochemical and other industries Mechanical laboratories, is factories, schools and scientific research units ideal experimental equipment.
2.Standards
Test methods meet the standard GB10128-88 "metal room temperature torsion test method", ISO7800: 1984 "metal wire one-way torsion test method", ASTM A938-2004 "metal wire torsion test standard test method", EN, JIS torsion test Requirements. Replace corresponding accessories can also meet the GB943-1988, HB7595-2011, GJB358-1987 for bolts torsion test requirements.
