ASTM A and ISO address the requirements for simple torsion (twist) testing of metallic wire. Both testing standards require that a wire specimen be. This standard is issued under the fixed designation A ; the number 1 This test method is under the jurisdiction of ASTM Committee A01 on Steel,. Stainless . ASTM A covers torsion testing of wire. ASTM A provides knowledge of the ductility of a wire when under torsion loading. A torsional test machine with.

Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience.
ASTM A938 Torsional Test of Wire
Gripping Maintaining the rate of turning Applying a constant tensile force Accommodating various specimen lengths Shielding against broken specimen fragments Automatic turn counting Measuring and plotting torque Instron Aa938 Gripping – Many common wire diameters can be gripped with standard drill style chucks.
Bluehill Universal Brochure Bluehill Universal Software is built from the ground-up a9388 touch interaction and an intuitive user experience. MicroTorsion Series As the preferred solution for low-force torsion testing and component in-service simulation, the MT MicroTorsion Series test wires, fasteners, switches, and springs in the biomedical, automotive, and aerospace industries.
ASTM A ISO Torsion Testing Wire – Instron
Torque versus Rotation plots are automatically generated during the test and indicate where the wire yields and fractures. Specimen Lengths – Instron’s MT torsion testers feature an adjustable tailstock assembly that allows for easy adjustment of the test opening.
Software for Series Systems. Keyless chucks W-MT01 offer a toothed profile that helps reduce slippage.
Email addresses must contain the symbol. Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill. Upon failure, the number of turns should be recorded.

Challenges The challenges of testing wire to these standards are: Speed of Twisting – The rate of testing can vary and both standards provide recommended ranges that are based on the wire diameter. Both testing standards require that a wire specimen be twisted about the longitudinal axis until it fails.
Tests cannot be run when the door is opened and the rugged Lexan shield helps protect the operator from broken specimen fragments that may be ejected during failure.
How can we help you? Total Turns Measurement – The total number of turns to fracture are directly measured by a digital rotary encoder and automatically ast, by the testing software.
