ASTM A938 PDF

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.

Glossary of Materials Testing Terms. 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. Concrete, Asphalt and Rock.

Subscribe to Astk News! Specimen Lengths – Instron’s MT torsion testers feature an adjustable tailstock assembly that allows for easy adjustment of the test opening. WaveMatrix 2 for Dynamic Testing.

How can we help you? 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.

ASTM A938 Torsional Test of Wire

Speed of Twisting – The rate of testing can vary and both standards provide asttm ranges that are based on the wire diameter. Axial Tensile Force – To prevent the wire from bending away from the axis of rotation, a small a398 load is required to keep the specimen straight during testing. The MT torsion models are available with extended length if longer specimen lengths are required. Next Checking to see if you are a returning visitor….

ASTM A – 07 Standard Test Method for Torsion Testing of Wire

Tests cannot be run when the door is opened and the rugged Lexan shield helps protect the operator from broken specimen asmt that may be ejected during failure. The MT torsion systems are supplied with precision torque cells that can measure torque accurately down to 0. Keyed chucks W-MTB provide smaller diameter clamping.

Software for Series Systems. Keyless chucks W-MT01 offer a toothed profile that helps reduce slippage. Guide rails enable the assembly to move freely in the axial direction while a test is being performed.

Email addresses must contain the symbol. 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.

Email addresses can only contain letters, numbers and the following special characters: MicroTorsion Series As the preferred solution for low-force torsion testing and component in-service simulation, the Axtm MicroTorsion Series test wires, fasteners, switches, and springs in the axtm, automotive, and aerospace industries.

Universal materials a9938 software for static hydraulic, electromechanical and torsion testing systems – WBB. Both testing standards require that a wire specimen be twisted about the longitudinal axis until it fails.

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.

Bluehill Universal Brochure Bluehill Universal Software is built from the ground-up wstm touch interaction and an intuitive user experience.

Torque versus Rotation plots are automatically generated during the test and indicate where the wire yields and fractures. 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.
