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.

Next Checking to see if you are a returning visitor…. Speed of Twisting – The rate of testing can vary and both standards provide recommended ranges that are based on the wire diameter. Subscribe to Instron News! Keyed chucks W-MTB provide smaller diameter clamping. Contact Us View Accessories Catalog.
Software for Series Systems. Email addresses must contain the symbol. 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 Solution Gripping – Many common wire diameters can be gripped with standard drill style chucks.
Upon failure, the number of turns should be recorded. 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.
Email addresses can only contain letters, numbers and the following special characters: Check this box to receive pertinent commercial email from Instron focusing on products, upcoming events, and more! The real-time measurement data can also be plotted graphically during the test.
Subscribe to Our Newsletters. 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. Specimen Lengths – Instron’s MT torsion testers feature an adjustable tailstock assembly that allows for easy adjustment of the test opening.
Please confirm that astn agree with our privacy and cookies policy to submit this form.
Our MT1 and MT2 torsion test systems offer an axial preload assembly that provides a constant axial force and can be adjusted for different size specimens.
Bluehill Universal Brochure Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. This plot will show where the wire yielded during the twist test, as well as the failure point and profile. 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.
Total Turns Measurement – S938 total number of turns to fracture are directly measured by a digital rotary encoder and automatically recorded by the testing software. 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.
Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. Challenges The challenges of testing wire to these standards are: Keyless chucks W-MT01 offer a adtm profile that helps reduce slippage.
Torque versus Rotation plots are automatically generated during the test and indicate where the wire yields and fractures. Bluehill LE for Basic Testing.
Guide rails enable the assembly to move freely in the axial direction while a test is being performed. How can we asttm you?
Both testing standards require that a wire specimen be twisted about the longitudinal axis until it fails. Aa938 materials testing software for static hydraulic, electromechanical and torsion testing systems – WBB. Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill.
The MT torsion systems are supplied with precision torque cells that can measure torque accurately down to 0.
