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.

Both testing qstm require that a wire specimen be twisted about the longitudinal axis until it fails. Please confirm that you agree with our privacy and cookies policy to submit this form. Xstm 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 LE for Basic Testing. 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.
Torsion Testing Wire to ASTM A938 and ISO 7800
Upon failure, the number of turns should be recorded. 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. Universal materials testing software for static hydraulic, electromechanical and torsion testing systems – WBB.
Glossary of Materials Testing Terms. Torque versus Rotation plots are automatically generated during the test and indicate where the wire yields and fractures. Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill. Asym Training At Your Facility.
X938 chucks W-MTB provide smaller diameter clamping.
ASTM A ISO Torsion Testing Wire – Instron
Tests cannot be run when 9a38 door is opened and the rugged Lexan shield helps protect the operator from broken specimen fragments that may be ejected during failure. WaveMatrix 2 for Dynamic Testing. 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.
The MT torsion models are available with extended length if longer specimen lengths are required. x938
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: Email addresses can only contain letters, numbers and the following special characters: Guide rails enable the assembly to move ashm in the axial direction while a test is being performed.
Additionally, some labs want to know the qstm required for specimen failure and would also like to see a plot astmm torque versus the number of turns for the entire test. Software for Series Systems. This plot will show where the wire yielded during the twist test, as well as the failure point and profile. Axial Tensile Force – To prevent the wire from bending away from the axis of rotation, a small tensile load is required to keep the specimen straight during testing.
How can we help you? Email addresses must contain the symbol. 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.

Keyless chucks W-MT01 offer a toothed profile that helps reduce slippage. Bluehill Universal Brochure Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. Next Checking to see if you are a returning visitor…. Specimen Lengths – Instron’s MT torsion testers feature an adjustable tailstock assembly that allows for easy adjustment of the test opening.
The MT torsion systems are supplied with precision torque cells that can measure torque accurately down to 0. The real-time measurement data can also be plotted graphically during the test.
Speed of Twisting – The rate of testing can vary and both standards provide recommended ranges that are based on the wire diameter. Subscribe to Our Newsletters.
