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 Asmt Gripping – Many common wire diameters can be gripped with standard drill style chucks.

The MT torsion systems are supplied with precision torque cells that can measure torque accurately down to 0.

Keyless chucks W-MT01 offer a toothed profile that helps reduce slippage. Next Checking to see if you are a returning visitor…. Upon failure, the number of turns should be recorded. Total Turns Measurement – The total number of turns to fracture are directly measured by a digital rotary encoder and automatically recorded by the testing software.

ASTM A – 18 Standard Test Method for Torsion Testing of Wire

Specimen Lengths – Instron’s MT torsion testers feature an adjustable tailstock assembly that allows for easy adjustment of the test opening. 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. Software for Series Systems. Glossary of Materials Testing Terms. Lathe style chucks can be supplied for larger diameters and can also be modified to allow for clamping a wire with a 90 degree bend on the ends.

Contact Us View Accessories Catalog. Torque versus Rotation plots are automatically generated during the test and indicate where the wire yields and fractures.

Both testing standards require that a wire specimen be twisted about the longitudinal axis until it fails. By continuing to aastm our site, you accept our cookie policy.

Asm to Instron News! Our MT1 and MT2 torsion test systems offer an axial asfm assembly that provides a constant axial force and can be adjusted for different size specimens. Check this box to receive pertinent commercial email from Instron focusing on products, upcoming events, and more!

Additionally, some labs want to know the torque required for specimen failure and would also like to see a plot of torque versus the number of turns for the entire test. Speed of Twisting – The rate of testing can vary and both standards provide recommended ranges that are based on the wire diameter. Email addresses must contain the symbol.
