Onsite Training At Your Facility. The MT torsion asym are supplied with precision torque cells that can measure torque accurately down to 0. Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill.

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

Email addresses can only contain letters, numbers and the following special characters: Bluehill LE for Basic Testing. Software for Series Systems. Speed of Twisting – The rate of testing can vary and both standards provide recommended ranges that are based on the wire diameter.

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 x938 test.

Torque versus Rotation plots are automatically generated during the test and indicate where the wire yields and fractures. Subscribe to Instron News!
